Gulf Specimen Marine Lab founder Jack Rudloe feeding nurse sharks.

If there’s one thing we have learned in 3-plus years of doing this project, it’s that everything eats blue crabs.  If you’ve watched our videos over the years, you’ve seen a gull eating one on Saint George Island.  You’ve seen (and heard) a loggerhead turtle crunch into one.  And in the video above, two octopi wrestle for the tasty treat at the Gulf Specimen Marine Lab in Panacea, Florida (That turtle shot was taken there as well, a few months back).  Lab founder Jack Rudloe spent some time with us, feeding sharks, hermit crabs, and various fish species.  It gave us a great chance to see many of the species that we cover in this blog, and many that we don’t, in action.

In the 50 years since Rudloe founded Gulf Specimen, the facility has served an eclectic range of services.

Its aquarium features many of the small critters that we’ve chronicled Randall and David studying in Alligator Harbor, Saint Joseph Bay, or Wakulla Beach.  You won’t see any orcas doing backflips for a fish treat.  These are the creatures of our coasts, many of them common (like fiddler crabs), some of them rare (like a white blue crab).  If it’s safe to touch the animals, you can (consult the signs on the tanks).

Loggerhead at Gulf Specimen Marine LabFor almost as long as its been open, Gulf Specimen has run a Sea Turtle Program to rehabilitate injured loggerhead and Kemp’s Ridley turtles.  They release 15-20 a year, many of which have swallowed fishing hooks.  The turtle in the aforementioned video is Allie the Loggerhead, released after a year in their care (full story here).  The loggerhead that tries to eat our GoPro camera in the video above is Little Girl, who is on display right now.

And then there’s the reason the lab was originally created, to provide specimens of animals to researchers, both medical and academic.  This keeps animals coming in and going out, so that the critter lineup remains somewhat fluid.

In their outreach in education initiatives, their goals mirror our own on the In the Grass, On the Reef project, only in a more up close and tactile manner.  They want you to know about the critters and their habitats, the threats facing them, and the benefits they provide us.  With their Seamobile, they can take that mission (and the critters) on the road to events like the St. Marks Stone Crab Festival.  After people crack open their claws, they could go and learn about the world their food had inhabited.  After the last year we have learned that this food only gets on your plate when there is a balance between these animals and their environmental conditions.  Sometimes, that balance is off, whether it is an overabundance of oyster drills in Apalachicola or, as we see in the video, octopus in crab traps.  It’s one thing to hear that crabs are being eaten.  It really comes alive, though, when you see it happening.  That’s mission we share with the Gulf Specimen Lab.

Over the next few months, we’ll be seeking out others who work to bring the big, wild, messy outdoors to you.  Is there anyone that you think we should be talking to? Let us know!

What is that octopus hiding under its tentacles?

Alex Reed inspects rubble from the Alum Bluff landslide.

It’s amazing to see how much can change in one year on the Apalachicola River.  I’ve previously mentioned the smaller sand bars and higher water.  But the most striking visual difference is in the face of Alum Bluff, probably the iconic image of the upper river. In part 1 of this adventure, we approached it from land to be rewarded with possibly the best view of the river and the forest around it.  In part 2, we kayak up to it.  Last year, we camped there and had activities in the evening and following morning that kept me from just being able to hang out and enjoy the bluff from my boat.  As I did so this year, Alex Reed, our co-captain as well as a geologist, was inspecting the rubble from a landslide that occurred earlier in the year.  Some of the rocks unearthed were millions of years old.

A few miles down the river, we explored an area that had been on my mind as RiverTrek approached.  I was hoping that this year’s rain would let us penetrate deeper into Sutton Lake, a place that Dan Tonsmeire calls the “quintessential” backwoods swamp.  That’s my favorite part of the video, as we make our way well past where we did last year.  As you paddle the big, wide Apalachicola, you pass so many creeks, sloughs, and other side channels.  Behind the trees could be an Aspalaga Blue Spring (where we hiked in part 1), any branch off of the river might take you back to a dark, canopied swamp like Sutton Lake.  The more I paddle the river, the more I am aware of how little of the basin I’ve actually seen.

It’s a lot to fit into two videos.  I want to show you the river; that’s why I go.  But we paddled with a lot of interesting people with some interesting stories, many of which I couldn’t fit into the videos without making a full blown program of it (maybe I should do that… would any of you watch it?).  Here are a few interesting bits  about my fellow RiverTrekkers:

George Blakely and Zone 5

Zone 5 in a Personal Floatation DeviceIn several shots, you see a dog running across the mouth of a cave, down a steep path, or sitting calmly in a canoe.  That’s Zone 5, a rescue dog that accompanies George Blakely on his adventures (she even has her own pink personal flotation device).  George explains where he got such a cool name.

“In photography, Ansel Adams, he had his own system for the different tones, zones zero through nine.  Zone five is middle grey.  When she runs really fast, which she does frequently, except when she’s in the canoe, she’s middle grey.”

Todd Engstrom

Todd Engstrom recounts his search for the ivory billed woodpecker along the Apalachicola River.

Todd Engstrom recounts his search for the ivory billed woodpecker along the Apalachicola River.

Todd is an ornithologist with a unique history with the Apalachicola.  He was sent to look for evidence of a bird that was thought to have been extinct for several decades.  The ivory billed woodpecker is one of the largest species of woodpecker in the world, measuring about 20 inches long.  When one was thought to have been sighted in Arkansas (a sighting that is now in doubt), The Cornell Lab of Ornithology sent Todd to scour likely habitat in the Apalachicola River basin.  As opposed to the red cockaded woodpecker, which prefers upland forests, the ivory billed prefers lowland, old growth forests.  Todd spent four months searching, from Lake Seminole to the bottom of the river.

“As a consequence of that, I was camping out, boating on the river, going to field sites.  Just really enjoyed it.  Fell in love with it.”

Su Ecenia & Jill Lingard

In the video, Georgia mentions that this year’s group smashed the fundraising record for RiverTrek (after last year’s group raised more than any other group combined).  Su raised the most money, over $5,500.  Jill, despite living out of the area in Gainesville, had the most individual donors with over 40.  That provides much needed funds for the Apalachicola Riverkeeper.  Jill was one of three paddlers from outside of Tallahassee or the surrounding area.  Scott Keyes is from Naples, and Mim Duncan is from Sebastian.

Chris Robertson

Chris is a returnee from RiverTrek 2012, and one of our co-captains.  For him, a highlight of the trip came on the third morning.

“It was the time of the trip when you could finally let go of everything that goes on back in the quote-unquote real world, and just kind of immerse yourself in the river and what you’re doing.  When you reach that point, it’s very emotionally and spiritually recharging.”

Just me and the river on RiverTrek 2012, somewhere between Estiffinulga and Wewahitchka.

I get was Chris is saying.  After a couple of days, the trip starts to feel like your reality.  You’ve woken up a for couple of mornings where you stick your head out of your tent and see the river.  Last year, I had a similar experience on the third day.  I spent some time paddling alone, where the only visible signs of civilization were within my kayak.  One of my favorite things about the trip is the people, but I treasured my one-on-one time with the river.

Who knows what my next adventure on the Apachicola River Basin will be.  RiverTrekker Mike Mendez has talked about an extended trip starting on the Flint or Chattahoochee.  Doug Alderson is mulling a hiking trip in the many protected lands around the river.  I’ll be planning other EcoAdventures around the area, all the while knowing that there is some corner of the river basin that needs to be further explored.

Next on In the Grass, On the Reef

The Gulf Specimen Marine Lab takes their critters on the road.  Meanwhile, back at their aquarium, tentacles are a-flailing over a tasty treat and marine megafauna try to eat our GoPro camera.  Also, I begin a new adventure as a member of the Florida Greenways and Trails Council.  I’ll give you the lowdown as the Council looks for ways to connect existing trail systems and create more opportunities for the kind of multi-day EcoAdventure featured in our RiverTrek videos.

Planning Your Own Apalachicola River Kayak Camping Adventure

The Apalachicola Blueway is managed by the Apalachicola Riverkeeper, and the trail was mapped and the Blueway Guide created by Florida DEP’s Office of Greenways and Trails.

Part 2 of the RiverTrek 2013 Adventure is now online. Witness some of the long term damage done to the river, and tag along as we take advantage of this year’s higher water to paddle into one of our area’s “quintessential” swamps. If you missed Part 1, catch it here.

Rob Diaz de Villegas WFSU-TV

After having partaken in the last couple of RiverTrek paddles down the Apalachicola River, I have to commend Georgia Ackerman and Doug Alderson for the work they put in to planning the trips.  A dozen paddlers of multiple experience levels paddle 107 + miles (once you factor in side trips) over five days, camping along the way.  Even a relative newbie like me can tag along and find myself alive in Apalachicola five days later.

You’re in good hands having expert paddlers like Doug and Georgia in charge.  But, thanks to a lot of hard work by Doug, any moderately experienced paddler has the tools to plan their own RiverTrek.  Where do you camp?  Where can you refill your water?  On what sand bar can you have a Jetboil tea party?  All of those questions are made clearer with the Apalachicola Blueway Paddling Trail guide.

Choose your adventure

The River Styx. Incorporating creeks and tributaries into your Apalachicola River adventure can give you a more intimate feel for the river.

Every year for RiverTrek, paddlers have to find a way to extricate themselves from work and family obligations for five days to paddle the entirety of the Apalachicola River.  But not every trip has to eat your whole week.  Consulting the handy dandy Apalachicola Blueway Trail Guide, you’ll see that there are multiple locations to put in and take out along the river.

Last year for a RiverTrek warm up paddle, I accompanied some of my fellow trekkers on a trip from the River Styx to Owl Creek.  This was an 18 mile day trip that let us see a couple of side channels as well as the river itself.  This year on the Trek, I was extracted at Estiffinulga after two days of paddling and one night of camping.  You have a lot of options, especially if you factor in the many creeks and tributaries in the lower river, in the Apalachicola Wildlife and Environmental Area (Watch our EcoAdventure in the Apalachicola WEA).

Once you know how many days you’ll be able to spend on your trip, decide how many miles you’re able to do a day.  This year, we averaged just over 20 miles a day at about 5 – 6 miles an hour, and we did 4 miles an hour with last year’s record low flows.  Of course, you’ll want to make sure that there’s a place for you to sleep at the end of the day…

Camping

Estiffinulga Breakfast

Breakfast on the Estiffinulga sand bar on RiverTrek 2012. Look at how big it is! The Apalachicola is full of high, wide sand bars…

In Part 1 of our video, our trip leaders found the Alum Bluff sand bar too small for sixteen campers.  No problem.  There was another high, wide sand bar just a mile to the north, and it wasn’t even on the trail map as a campsite.  The upper Apalachicola has numerous such sand bars, which gives you flexibility in planning your trip.  Once you get past Wewahitchka at mile 42 (mile markers start at 106 at the Woodruff Dam and work their way down to 0 at Apalachicola), there are less options directly on the main channel.

This year, we had some rain and the Army Corps of Engineers had more water to release from the Woodruff Dam.  That means that the river rose a little overnight, and so we had to pull our kayaks a little further up on the bar.  Which brings me to…

Staying high and dry

Estiffinulga Sand Bar Camp Site

…Estiffinulga sand bar on RiverTrek 2013. For all I know, the spot where the breakfast table is in the picture above is under my kayak here. Checking the U.S. Geological Survey’s river gauges can give you an idea about how big some of these sand bars might be.

RiverTrek occurs in October every year, during the river’s low water season.  The high water season begins in late February and continues through May.  It’s usually lowest in the fall.  This means that, typically, there are more sand bars exposed for camping then.  Typically.  Whereas last year, drought conditions kept the sand bars as exposed as they’ve ever been, this year’s rain has left them much smaller.  That’s the beauty of the outdoors.  I went on the same trip two years in a row, and things looked different in a lot of places.  But how can you know what to expect when you plan your trip?

For best camping conditions, the Blueway Guide recommends that the US Geological Survey gauge at Chattahoochee remains below 44 feet, and below 5.5 feet at the USGS Sumatra gauge.  Looking at the gauge info at the link above, I see that Chattahoochee was around 42.5 with a spike to 43.5 (when water is released from the dam) for the first day of RiverTrek.  At that height, Alum Bluff was too small for our group and Estiffinulga sand bar (the day 2 camp site) looked nice and cozy.  Within a couple of days, the gauge readings swelled to near 44 feet.

Bring all the gear you will need

The Florida Department of Environmental Protection’s Office of Greenways and Trails (where Doug works) has compiled some helpful checklists to make sure you bring everything you need for kayak camping trip.  The bar on the right side of their Florida Circumnavigational Saltwater Paddling Trail web site has links to safety tips and a recommended gear list.  You could also watch this short video we did with Georgia and her husband and RiverTrek alum Rick Zelznak, on packing for kayak camping.  In about five minutes, they give you a quick rundown of what to bring, how to organize it in your dry bags, and how to fit it all into your kayak (this was based on Georgia’s RiverTrek 2011 experience).

Plan your route.  Check the river gauges.  Make sure you have all the gear you need, and that you can fit it into your kayak or canoe.  Experience one of Florida’s great rivers.

We work hard on these videos, but it’s never the same as being there.

Video: Kayaking in, and hiking around, the Apalachicola River.

Last year’s RiverTrek kicked off a year where we made the Apalachicola River and Bay a focus of the In the Grass, On the Reef (IGOR) project.  As with this year’s video, last year’s was a two-parter.  Watch Part 1, Days 1 and 2, here.  Watch Part 2, Days 3 through 5, here.  In Part 2, we looked at how low river flows last year precipitated the crash of the Apalachicola Bay oyster fishery.  Shortly after, IGOR team member Dr. David Kimbro began investigating the oyster stocks more closely.  You can follow that research here.

This video focuses on a 5-day kayak and canoe adventure down Florida’s longest river.  RiverTrek is a fundraiser for the Apalachicola Riverkeeper.  Riverkeeper staff and volunteers have been an immense help in producing our Apalachicola videos and in getting them seen.  Thank you to Dan, Shannon, Tom, Georgia, Doug, and everyone else for allowing us to be part of the adventure.

Sunset on the northern Apalachicola River, from our day one camp site.

Getting back on the Apalachicola River for RiverTrek 2013 felt a little bit like rekindling a fling that was cut short. Last year we had a couple of good dates.  On the first one, we got coffee- kayaking from the River Styx to Owl Creek for 18 miles of getting-to-know-you.  Then the second date, RiverTrek 2012, was a crazy all night- all week- affair where we did just about everything.  Spelunking at Means Creek, climbing the tallest river bluff in Florida (Alum Bluff), climbing Sand Mountain- all while getting to experience the entire river channel.  How do I follow up on that amazing date?  By spending a lot of the next year in Apalachicola Bay following oyster research.  Is that like dating someone’s sister?

I swear I was thinking about you the whole time I was with her.  I can’t help but to think about you when I’m with her, especially with all that has happened over the last year.  The truth is, I’ve thought about you quite a bit since I last saw you.

Aspalaga Blue Spring

Aspalaga Blue Spring lies just a mile off of the Apalachicola River, at mile marker 98. From a sand bar on the west side, one would bushwhack a mile into the woods to find it.

And then, finally, there I was again for RiverTrek 2013.  The Apalachicola seemed familiar, yet different, like a friend you haven’t seen for a little while.  The face is the same, but a little older.  The hair is different; they have gained or lost weight.  After last year’s drought and record low flows, higher water this year made for a slightly different feel.  As you can see in the video, we had choices to make about where we would sleep the first night, as the Alum Bluff sand bar was much more submerged than it was last year.

You’re looking good this year.  You’re looking fuller, faster.

More water is flowing in the creeks and sloughs.

No, I didn’t think your sand bars looked too big last year.  I like your sand bars.  I always think you look good.

Coming out of a cave on Means Creek

My fellow RiverTrekkers wait for me as I prepare to climb out of a cave on Means Creek. This group paddled to raise money for the Apalachicola Riverkeeper, an organization that advocates for Florida’s share of water in the Apalachicola/ Chattahoochee/ Flint basin. Over the last few decades, many have fought for the Apalachicola, which is downstream of the other two rivers.

It’s not an exclusive relationship.  Just as I explore and make videos on Slave Canal or Lake Lafayette, many others have a relationship with the Apalachicola River.  Many people have a much deeper connection with her than I do; I know my place.

The thing is, you worry us sometimes.  I mean, you’re amazing.  You’ve put up with a lot, and you’ve been mistreated.  You’ve been starved and scarred with dykes.  Yet you do so much for so many people.  

A lot of the time, we don’t appreciate something until we’re in danger of losing it.  The crash of the Apalachicola Bay oyster fishery was an eye opener for a lot of people as to how reliant the Bay is on the river flow.  But this is a fight that has been waged for decades, between Florida, Georgia, and Alabama, and against the Army Corps of Engineers’ policies in managing the river and its flow.  In this video, Part 1 of 2, we explore the area around the river, bushwhacking through the woods to clear, cool springs and climbing in the bluffs above the river for a better vantage point.  Next week, in Part 2, we take a quick look at the decades long struggle with the Corps, and see that oyster beds aren’t the only habitat that need fresh water.  And we kayak into the “quintessential” cypress/ tupelo swamp- Sutton Lake.

Soccer Balls, Bucky Balls, #sciooceans, & Purple Gallinules

Rob Diaz de Villegas WFSU-TV

Dr. Harold Kroto has a soccer ball.  Drs. Randall Hughes and David Kimbro have WFSU-TV (and me).  IGOR associate producer Rebecca Wilkerson produced the video above, the first SciTalk, our new video series on how scientists talk to people who aren’t scientists, about science.  It stars Dr. Kroto, a Nobel Laureate for his co-discovery of buckminsterfullerenes.  And hey, how about that, bucky balls look exactly like soccer balls!  For Kroto’s audiences, this is the gateway to the complex chemistry of carbon composites, made simple and clean.

Simple and clean is not so much our approach to communicating science.  We do ecology, and ecology has a lot of connectedness.  A river carries fresh water and nutrients (our participation in the RiverTrek paddle down the Apalachicola the last couple of years).  If that water doesn’t flow, there can be problems with oysters in the bay (our coverage of David’s research into the failure of Apalachicola Bay reefs).  When the oysters die, the seafood industry crashes (how we incorporated oystermen into our coverage of David’s research).

Old Growth Cypress and Ogeechee Tupelo in Sutton Lake, off of the Apalachicola River on RiverTrek 2013.

How about a kayak adventure as a way to communicate ecology? On this year’s RiverTrek (also this past week), we explored ecosystems other than oysters that are affected by low water flow. This is Sutton lake, which runs off of the Apalachicola River. With last year’s record low flow, we never got to paddle to these old growth cypress and ogeechee tupelo trees further off the river. In our upcoming RiverTrek 2013 videos, we get deeper into this and other ecosystems surrounding the river. Look for a two-part EcoAdventure in November.

We don’t have a soccer ball.  We have a soccer stadium.

Sometimes you can shrink a research topic down into a icon; sometimes you zoom out and look at the world around it.

Our first SciTalk video happened to air the same week as Science Online Oceans, a conference where marine scientists are hard at work trying to get you (the nonscientists reading this) to care about ocean science.  I moderated a discussion on scientist/ filmmaker collaboration (follow the online side of that discussion at #sciofilmmaker), and attended a few very helpful sessions where I gained some knowledge I’d like to use.  Technology offers some tantalizing opportunities, but new gadgets and web tools aren’t an automatic guarantee that people will pay attention to and absorb your message.  As you can tell from the hashtags, for instance, ScioOceans is a Twitter-heavy affair. But who’s seeing our tweets?  And I would love to set up a virtual field trip to an oyster reef for school children using a Google Meetup.  There are so many new tools, and yet, watching the video above, I can’t help but notice how engaged the kids look as they build bucky ball models.  Dr. Kroto is doing a good deal of outreach in person, with a soccer ball.  In the end, the content of the message is still more important than the device that delivers it.

We will continue our SciTalk videos (not the newest technology, but still effective), looking at what scientists, educators, and community organizations are doing to make science interesting.  We’ll also continue exploring our local ecology.  Look for a two part RiverTrek 2013 EcoAdventure.  The water was higher on the Apalachicola this year, and we’re exploring more of the area around it.

Of course, when you’re communicating ecology, flashy animals are always a big help.  So I leave you with this purple gallinule, spotted on our ScioOceans Everglades field trip (#scioglades).

Rob Diaz de Villegas WFSU-TV

Sunrise at Piney Z. LakeAs you can see in the video, a sunrise is always worth getting up for.  All the better if a sunrise that beautiful is a mere fifteen minutes from my house.  Moments before the sun peaked over the tree line to gaze at its reflection in Piney Z. Lake, we heard a ruckus of birds as they flew overhead.  We came to the Lafayette Heritage Trail Park for kayaking, mountain biking, and an airboat ride, but the reason you schedule a shoot at that time is for lighting and wildlife.  Florida Fish and Wildlife biologist Michael Hill told us that they’re getting the park onto the Great Florida Birding and Wildlife Trail.  My favorite critter of the day was the juvenile green heron you see at 0:32, but it was also fun to see anhinga, gators, and the occasional osprey.  The park also has gallinules, wood ducks (you can see a couple of wood duck boxes in the video), and over three hundred wood stork nests (located on Lower Lake Lafayette).

Tussocks on Lower Lake Lafayette

The Lower Lake Lafayette portion of the paddling trail is currently clogged with tussocks. When the water gets low, dead plant material accumulates and traps seeds. The seeds grow in these mats, which become floating islands when the water gets higher. The dead vegetation you see in this photo is a result of herbicides, the first step in clearing the trail.

My wife and I have been hiking the multi-use trails in the park pretty much since it opened a few short years ago.  We usually start in Tom Brown Park, make our way along Upper Lake Lafayette and then to Piney Z. Lake.  If we have the time, we head along the dam separating Piney Z. and Lower Lake Lafayette, and across the train tracks into the J.R. Alford Greenway.  Walking all that way, you get to wondering about the dams separating the lakes and the “fishing fingers” on Piney Z.  Those are remnants of the Piney Z. Plantation, which added the earthen dams and dykes in the 1940’s.  The fingers are an interesting feature, letting you walk towards the center of the lake and offering some nice views of the dykes that the City of Tallahassee turned into small islands when they made the park.  All of that damming has altered the hydrology of what was once a singular Lake Lafayette.  This is why the paddling trail on Lower Laffayette has been closed for the last year, as our recent big bad drought lowered the lake and caused it to become choked with vegetation.  The trail will soon be cleared and will open by Thanksgiving 2013.  Thanks to Michael and his airboat (and to Liz Sparks for setting us up with him), we were able to get a unique look at the lake and its floating islands of vegetation, called tussocks.  The dams prevent the Lake’s normal drought cycles, and so the trails require some extra maintenance.

Ardisia crenata

Ardisia crenata, and invasive plant found in the Lafayette Heritage Trail Park.

On land, the multi-use trails need maintenance as well, and there is one thing that any of us who use the park can help with.  Chuck Goodheart, who manages the trails, is looking for help with invasive plant species, in particular, Ardisia crenata.  This plant threatens to overtake native plants within the park.  The city had spent thousands of dollars to try and eradicate it, only to have it return.  Now they’re turning to people who use the trail.  People have learned to carry bags when they walk their dogs; we can likewise bag and remove the plants and their berries when we see them in the park.  In fact, there are bags for dog waste near the Piney Z. parking area.  If people buy into it, it should be a cost effective approach.

I want to thank Chuck for riding his bike on camera after recently having surgery on his foot.  And I want to thank Georgia Ackerman for once again lending me a kayak.  Todd Engstrom and I both got to try out the kayaks we’re taking on RiverTrek 2013, which is- oh my! – two weeks away.  Todd, Georgia, and Liz are a great group to paddle with.  RiverTrek gets me thinking about the connection between the Apalachicola River and Bay, and the bay’s ever important estuarine ecosystems.  This dynamic is at play on Lower Lake Lafayette, which flows into the St. Marks River, which itself flows into the St. Marks Refuge with its vast marshes.  Upper Lafayette has a sinkhole that drains into the Floridan aquifer, the source of water for most of north Florida and parts of South Georgia.  The aquifer also feeds springs that feed rivers that ultimately feed the Gulf.  Nature has this “six degrees of Kevin Bacon” thing going on, especially when it comes to the way water moves.  That includes rain and everything it carries with it from the roadways and lawns in the developed areas around Lake Lafayette. (Watch as David Kimbro explains the natural- and unnatural- nitrogen cycle, and how oysters can help). In all the years I’ve been coming here, I had no idea about this, or the why the dams were there or what their effect on the lake is.  I’m glad I had this “closer to home” EcoAdventure to get to know a familiar place a little better.

Notes From the Field: Panama, Where Oysters Grow on Trees

A couple of months ago, we looked at the increasing number of mangroves surviving north of their range in Gulf coast marshes and wondered how it might change that habitat. On a research trip to Panama, Tanya Rogers got a good look at how mangroves interact with many species found in North Florida. There, oysters grow on trees.

Tanya Rogers FSU Coastal & Marine Lab/ Northeastern University

Installing predator exclusion cages in the rocky intertidal at Punta Culebra, on the Pacific coast of Panama.

Travel 1,100 miles due south of Miami, and before you know it you will collide with the Caribbean coast of Panama. Take a look around these shores and what will you find? Not just coral reefs as you might expect, but also seagrass beds, mangrove forests, and oysters – many of the same species, in fact, that are found in Florida, but arranged a bit differently. What are these oysters, seagrasses, and mangroves up to in the tropical parts of the world?

For a brief stint this summer I worked with Dr. Andrew Altieri at the Smithsonian Tropical Research Institute in Panama, exploring ecological questions similar to those we’ve been investigating in Florida. Dr. Altieri, much like my advisor, Dr. Kimbro, is interested in the ecology of marine communities, particularly the role of foundation species and the effects of environmental stress vs. consumers/predators in determining what grows where. In the mangroves, as well as on the rocky shores of the Panamanian Pacific coast, I helped set up several experiments using the same sort of experimental techniques as we used in Florida (cages, transplantation, etc.) to answer questions about species interactions in tropical environments. I hope I have the opportunity to return to Panama in the future as part of my graduate research.

Setting up a mangrove root transplant experiment in Bocas del Toro, on the Caribbean coast of Panama.

One interesting thing about the oysters in Panama (on the Caribbean side anyway) is that they grow almost exclusively on mangrove prop roots, and instead of one species, you can find up to five oyster species co-occurring. The oysters grow near the water’s surface, and below them the submerged roots can host an astonishing diversity of other marine invertebrates, including sponges, tunicates, anemones, and tube worms. I found it fascinating to swim below the mangroves, the roots like a maze of stalactites bedazzled with life of all colors and textures, fish darting through the labyrinth, the occasional crab deciding to take refuge on your head. Be on the lookout though for stinging box jellies, for they also enjoy these galleries. Just as in Florida, the mangroves and seagrass beds (which often border the mangroves), are important nursery habitats for juvenile fishes, which later venture out to the coral reefs.

RiverTrek 2013 Preview: A Year in the Apalachicola River and Bay

Rob Diaz de Villegas WFSU-TV

RiverTrek paddlers are raising funds for the Apalachicola Riverkeeper, an organization whose mission is to “provide stewardship and advocacy for the protection of the Apalachicola River and Bay, its tributaries and watersheds…” (participating media members do not raise funds).  At the end of the paddle, on October 12, there will be a reception in Battery Park in Apalachicola.  There, people can greet the paddlers and bring non-perishable food items in benefit of Franklin’s Promise.  Franklin’s Promise aids the families affected by the failure of the Apalachicola Bay oyster reefs.

IGOR chip- gastronomy 150“The Good Lord giveth, and Georgia and the Corps taketh away.” Those words were spoken by Jon Steverson, Executive Director of the Northwest Florida Water Management District.  He was testifying before Florida senators Bill Nelson (D) and Marco Rubio (R) during a special field hearing to address the collapse of the Apalachicola Bay oyster fishery.  The high-profile event, held two weeks ago in Apalachicola, marked almost one year into a particularly turbulent era for this region.  Just one year ago, I was preparing to kayak the Apalachicola River for RiverTrek 2012.  The winter bars in the bay were just days away from opening.  When they did, a lot changed, including the nature of the RiverTrek videos we were to make, and the In the Grass, On the Reef project as a whole.

As I prepare to cover RiverTrek 2013 (October 8-12), the answers to the Apalachicola’s water flow problems remain elusive, and frustration remains high.  Much of that frustration is aimed, as one might gather from the first sentence of this piece, at the state of Georgia and the Army Corps of Engineers.  Thirteen days into the job as Mobile District Commander, Colonel Jon Chytka absorbed decades of displeasure at the Corps’ management of the ACF basin.  “I’m going to try to find out why they sent you,” said Senator Nelson, “Why didn’t they send the generals that I’ve been talking to?”  Part of the frustration stems from the rigidity with which the Corps follows the ACF Water Control Manual, and their interpretation of the authority granted them by congress.  The economic impact of fresh water on Florida’s seafood industry is not given as much weight as its economic impact on Georgia agriculture.   The Endangered Species Act of 1973 is the only guarantor that the river flow is not set below 5,000 cubic feet per second (cfs), which is how low it stayed for 10 months starting May 1, 2012.  That qualifies as the lowest river flow in recorded history, and only endangered mussels and gulf sturgeon kept it from being lower.  Senator Rubio asked whether the Apalachicola oyster would qualify for such protection.  Crassostrea virginica, the common oyster, is the main oyster species found on the east coast of this country and in the Gulf of Mexico.  The oysters you see on the fringe of the coast are the same species as the larger ones harvested from the floor of the bay.  Apalachicola oysters are the same species as Chesapeake oysters.  To the letter of the law, and despite massive decline in oyster reefs worldwide, it is not an endangered species.

This oyster was retrieved from Dr. David Kimbro’s oyster experiment in Apalachicola Bay. They found it dead, with its meat having been eaten. Like many of the dead oysters they’ve found, it has oyster drill egg sacs growing on it. Each of the sacs (here growing on the “chin” of the oyster) contains 10-20 drills.  Low freshwater input to the bay increases its salinity, making the bay hospitable to oyster predators such as drills, crown conchs, and stone crabs.

A further source of frustration with the Corps is the speed with which the Manual is being updated.  As Col. Chytka pointed out, the process began in 2008 and was complicated by lawsuits, the amount of input from stakeholders in the affected states (over 3,000 comments), and the “technical complexities” of the system.  He projected that a draft of an Environmental Impact Statement would be ready in the Summer of 2015, after which they’d reopen it to comments and then finalize by 2016.  The oyster industry may not have that kind of time.  “I don’t see any hope for the near future,” said Shannon Hartsfield, President of the Franklin County Seafood Workers Association. “We don’t have a near future.”

The best-case scenario for the bay, as determined by the University of Florida’s Oyster Recovery Team, is full recovery within a couple of years.  That’s dependent on being able to place a significant amount of oyster shell at the bottom of the bay.  So far, Hartsfield estimates that they’ve covered 35-40% of Cat Point, historically one of Apalachicola’s most productive bars.  By the end of the current shelling project, he believes that they’ll have covered 50% of another of the bay’s main bars, East Hole.  So, in addition to fresh water, oysters will still be lacking adequate substrate where spat could settle.  Additional funding will be needed to cover the bars fully.  There is, though, a glimmer of hope.

While frustration has remained high, so too has passion for the ecosystem and compassion for the people affected.  Says Hartsfield, “This is the first time, ever, out of all this disaster that Franklin County has experienced in the commercial (seafood) industry, that we’ve had any recognition.  And we appreciate it greatly.”  That recognition drew dozens to the steps of the Franklin County Courthouse that day to show support.  It has drawn researchers willing to work with oystermen to find solutions.  It has drawn a steady stream of regional and national media.  And it drew the United States Senate to a fishing town on Florida’s Forgotten Coast.  At the very least, lot of people are invested in finding a solution.

RiverTrek paddlers make their way to Sutton Lake, off of the Apalachicola River.  Last year, the water was too low to paddle to where the largest cypress trees in the Apalachicola watershed are found.  With a year of healthy rainfall, this year's paddlers will have better opportunities to explore the creeks and sloughs branching off of the river.

RiverTrek paddlers make their way to Sutton Lake, off of the Apalachicola River. Last year, the water was too low to paddle further into the lake, where the largest cypress trees in the Apalachicola watershed are found. With a year of healthy rainfall, this year’s paddlers will have better opportunities to explore the creeks and sloughs branching off of the river.

I’m one of the media members who have found themselves returning to cover the crisis, and it started with 105 miles of paddling.  Last year at this time, RiverTrek was to be a different perspective on our local ecology than our marsh, oyster reef, and seagrass videos.  A change of pace.  Instead, it kicked off a year of content that connected the river with the coast, and with the people who care for and rely on these resources.  I now find myself getting ready for this year’s journey with a better knowledge and feel for the story, but with much less certainty about the outcome.  RiverTrek will end after five days.  For this other, much larger Apalachicola adventure, we’ll all just have to keep on paddling.

Seagrass Wrack in the Salt Marsh – Blessing or Curse?

2-Minute Video: Seagrass wrack kills part of the marsh, but do its benefits outweigh the destruction?

Our videos to date have centered on biodiversity in the marsh and how it can make a marsh stronger against disturbances. As we see in this video, at least one type of disturbance might actually promote genetic and/ or species diversity.

This time of year if you look around salt marshes in our area, you’ll probably see a strip of dead plant material, or “wrack”, resting on top of the salt marsh plants around the high tide line. Look closer, and you’ll see that it’s mostly made up of seagrass leaves that have either been sloughed off naturally (seagrasses produce lots of new leaves in the summer and shed the old ones) or, occasionally, uprooted by boats driving through shallow seagrass beds. Look even closer (say, by picking it up), and you may just find a harmless marsh snake (or worse, a cottonmouth!) – in our experience, they like to hang out in the cool, moist areas under the wrack.

So is this wrack “good” or “bad” for the salt marsh? As with many things in life, the answer depends on your perspective. If you’re a snake or other critter that likes the habitat provided by the wrack, then it’s probably a good thing. On the other hand, if you’re one of my crew who finds that snake, and particularly if you’re Robyn who REALLY doesn’t like snakes, then it’s most definitely a bad thing. Or, if you happen to be the plant that the wrack settles on top of for long periods of time, then it’s a bad thing, because many of those plants die. But, if you’re a seed that is looking for a good spot to germinate in the marsh, then the bare spot created by the wrack is likely a good thing.

Bare spot left in salt marsh left by seagrass wrack.Last fall, David and I teamed up with Dr. Peter Macreadie from the University of Technology Sydney to find out how the bare “halos” created when wrack mats smother the underlying marsh plants influence the marsh sediments. It turns out, these bare areas store less carbon in the sediments than the nearby vegetated areas, which makes them less valuable as “sinks” for carbon dioxide. But as I mentioned earlier, the bare areas can also serve as a good spot for new plant species (or new genotype of a given species) to start growing, potentially increasing the overall diversity of the salt marsh. And as the seagrass wrack decays, it can provide valuable nutrients to the marsh sediments that support future plant growth. So what is the net outcome of all these good and bad effects?

We decided to do an experiment to answer that very question. As Ryan and Meagan will attest (along with almost everyone else in our labs who we enlisted to help us), this was a very labor-intensive experiment. First, we had to figure out how much wrack is typically in a given area of marsh. Then, we had to collect a lot of wrack, weigh it, assemble it into bags that could be “easily” moved to our experiment, and add it to cages that would help hold it in place. We’re talking ~1.5 tons of wrack picked up and moved to various spots!

FSU Coastal and Marine Lab technician Megan Murdock spin dries seagrass wrack for an experiment at the Saint Joseph Bay State Buffer Preserve.To make matters even more interesting, we had to soak the collected wrack in water to make sure it was all the same wetness, and then spin it around in mesh bags (think salad spinner on a very large scale) for a set amount of time to make sure we could get a consistent weight measurement on each bag. Anyone driving past the SJB Buffer Preserve in early September of last year must have wondered what craziness we were up to! And since we were interested in whether the length of time the wrack sits in one place influences its effects, or whether the number of times that wrack sits in a particular area matters, we moved all of this wrack around in our cages every 2 weeks for 3 months to mimic the movement of natural wrack by the tides. And then we measured everything we could think of to measure about the marsh.

We’re still going through all the data to determine the net outcome, but as expected, whether the wrack is a blessing or curse depends on who you are:

  • Juvenile blue crabs seem to like hanging out in the wrack (which is a much nicer surprise to find than a snake, even when they are feisty!)
  • Fiddler crabs also appear to like the wrack, with greater burrow numbers when wrack is present.
  • Contrary to our expectation that wrack would kill cordgrass and allow other plant species to recruit into the marsh, it looked like cordgrass actually did better in the wrack cages!
  • Sea lavender, a marsh plant with very pretty purple flowers, does not do so well when covered with wrack (Learn more about sea lavender and its relationship with mussels).

More to come once all the data are analyzed…

Apalachicola Oyster Research: SHARK WEEK

Since they’ve deployed their experimental cages in Apalachicola Bay, David Kimbro’s crew has had some go missing, while others have been found in this condition.  Missing buoys make potentially unharmed cages nearly impossible to find.  Until just yesterday, there have been no leads as to the identities of possible culprits.

Shark week? In Apalachicola Bay, oyster drills like this one are the animals that have inflicted the most damage.

I’ll eventually get to how our research on Apalachicola Bay oysters ties into shark week. But first, let me tell you about my history with the annual Shark Week, which is put on by the Discovery Channel. Growing up as a surfer in North Carolina, the best time to surf was in the late summer and early fall. After many warm months of zero waves in the spring and summer, we lived for tropical storms that would make their way into the south east….but not get too close. I hated those suckers that got too close, because fun waves would quickly turn into pigs being on the roof and lots of misfortune for my fellow North Carolinians.

Getting to the point, every August, I was barraged by the Discovery Channel with interesting stories about sharks. Cool… but as soon as the waves start coming up, I’d have all of these thoughts about sharks circling through my head. In fact, in the line-up the next morning, it was looked down upon to talk about the previous evening’s episode of Shark Week. Now, sharks are awesome and they are critical to the health of our marine environments, but I don’t like to think about them when I’m waiting for a wave.

Okay, enter our research on Apalachicola Bay’s oyster reefs. It has been a very wet summer and the waters are very murky… you can’t see squat under water. But that doesn’t deter us, because we have been full throttle this past year and especially this summer on the monitoring and experiments.

Disclaimer: the pronoun we = Nikkie and Hanna, who have to do all the diving and data collection. To be honest, I couldn’t have asked for a better graduate student and employee to lead this research project.

Now, another disclaimer is that Nikkie DISLIKES not being able to see under water. So, for all of the sites that I can’t free dive to collect the data (my scientific diver certification expired…next on the to-do list to fix), I would serve as shark/alligator bait by swimming on the surface of the water for 1/2 hour while others collected data below.

To be honest, I’ve skewered Nikkie about her fear and about needing me to serve as bait. BUT… then I got an email today from the crew, which happens to be the first mission since I departed from Florida for Massachussettes. This week, my lab is undergoing a Herculean effort to set up another experiment. In doing so today, they solved mystery of who/what has messed with all of our previous experiments and they simultaneously confirmed Nikkie’s fear. These experiments are protected by welded cages and marked with buoys, which have frequently and unfortunately gone missing. This is bad for our research funds, our time and for the data we need to understand Apalachicola and its oyster reefs.

So, in the spirit of the board game Clue...who dunna it?

Freaking sharks. Given Nikkie’s significant fear and my discounting of that fear, I sure felt bad getting this message from Hanna and Nikkie today. But hey, that’s what team Kimbro does for Apalachicola oysters!

(Edit 8/11/13.  FSU Coastal and Marine Lab’s Dr. Dean Grubbs IDs it as a bull shark.  Read more on this fact sheet from NOAA, from which we leave you with this quote: “Bull sharks are one of the three top sharks implicated in unprovoked fatal attacks throughout the world.”- Rob)
