Barrier Island Wildlife in the Florida Panhandle; Part 3 Here They Come

Barrier Island Wildlife in the Florida Panhandle; Part 3 Here They Come

The classic model of ecological succession begins with new land.  This could be new land formed by a sand bar, or a new landscape formed after a volcanic eruption, but new land none the less.  Then the pioneer community begins.  Based on the model, the plants need to be first, herbivores cannot survive unless there are plants already present.  When we teach students about maintaining aquaria, we actually begin with the bacteria community needed to breakdown the organic waste from the plants and animals when they arrive.  So, some would say “begin there”.  As the pioneer plant communities form, the pioneer herbivores arrive.  This would be followed by more advanced communities of plants and then more advanced communities of animals, until you reach the climax community.

But science understands that it is more complicated than that.  Each new member of the community would make chemical and physical changes to the environment that could allow new species to thrive while other existing ones die off.  Then those would make changes as well and the process is ALWAYS changing.  That there is never a true climax community, change is happening all of the time.  Then there was the case of Mt. St. Helens. 

St. Helens erupted in 1980 destroying 229 square miles of habitat.  This new landscape gave ecologists an opportunity to witness ecological succession firsthand.  Like everyone, they expected the pioneer plant community to arrive first, and so on.  But in some areas, it was the carnivores that arrived first, completely against the classic model.  These carnivores apparently survived the blast and began to wonder the new landscape.  How did they survive?  They survived by feeding on each other.  But eventually the pioneer plants did arrive, all creatures “got in line” and the world was good once again.  The interesting thing was it did not happen the way they thought it would.  It also shows the resiliency of life.

So, how did this process unfold on our barrier islands?  I do not know.  You would guess that it unfolded the way the model suggests – pioneer plants first, pioneer animals, more complex plants, more complex animals, barrier island ecosystem.  But as we have seen, there are several ways it could have started. 

What we do know is that the animals who made it to the islands had to do so by either swimming, flying, or walking.  For those who reached our islands on foot – beach mice, ants, etc.  this must have happened at a time when the island was still connected to the mainland.

For the swimmers, short swims like Indian Pass could be achieved by several species.  Deer and other small mammals may have been able to do this.  I have seen bears swim and assume coyotes could make short swims.  As the island continued to move with the tide and currents, the distance to the island would have increased.  The pass across the mouth of our estuaries, or across the intracoastal waterway, is now daunting for many of these swimmers – but not all.  I have seen eastern diamondback rattlesnakes swim across the ICW and have heard bears can still make this trip.  For the flyers, these distances do not seem to be an issue.  They easily, and often, do so.

If you imagine the early days of an island being low elevated sand, the new wildlife arrivals would face a daunting landscape.  Burrowers, such as ghost crabs, could easily make a living here.  Their burrows protect them from the elements and being scavengers, they would feed on anything the Gulf washed ashore – something they still do.  Sea turtles and shorebirds could easily use the sand bars for nesting, and probably preferred it due to the few predators around.  But eventually, the pioneer plants would become more established, allowing selected herbivores (who could survive in low elevation sand) to move in.  Next the dunes would form, providing new habitat (read part 2 of this series).  Additional herbivores, if they could reach the island, could now become established and at some point, the carnivores would enter the picture.

There would initially be a finite amount of space for inhabitation and competition for that space and its resources would be high.  Some would be more adapted to the environment than others, or physically stronger, or have a higher reproductive rate, to give them an edge over the others and the island wildlife community would begin.  This community would include such things as insects, worms, amphibians, reptiles, birds and mammals.  The marsh habitat would include aquatic species such as snails, clams, crabs, shrimp, and fish.  All would have had to be able to reach the island, find a suitable habitat for their needs, find suitable food, and out compete others who had made the trip across as well.  I was asked once as a college student – “who is a rhinoceros’s greatest competition?”  It was an oral exam, and I was very nervous.  My mind began reeling in all directions trying to think of what a rhino would have to compete for and WHO would be their greatest competitor.  And then, with a little discussion from my professors, it dawned on me.  Their greatest competitor would be another rhino.  The other rhino would be seeking the same resources, habitat, and mates as the original one.  Your first problem is with your own kind.  And so, it would be for barrier island wildlife.

With the arrival of humans, with their bridges and boats, additional creatures would be able to reach the islands and play a role in the competition, but that is another story, and we will discuss this more down the road.  In Part 4 we will look at the species that have inhabited the beaches of our barrier islands. 

Barrier Island Wildlife in the Florida Panhandle; Part 2 The Habitats

Barrier Island Wildlife in the Florida Panhandle; Part 2 The Habitats

The habitats of a barrier island are defined and driven by the plant communities there.  Seeds from the mainland must first reach the new island and they can do so using a variety of different methods.  Some come by wind, some by water, some by birds and other wildlife.  Some of these germinate, some do not.  Those that do, do so on a sandy island with little or no relief and must deal with the winds off the Gulf, which has salt spray.  Many of these mainland plants cannot tolerate this and never make it.  But some can… and do. 

The dune fields of panhandle barrier islands are awesome – so reaching over 50 ft. in height. This one is near the Big Sabine hike (notice white PVC markers).

These early plant communities are known as the pioneer community – meaning the earliest settlers.  In the process of succession pioneer communities are made of creatures that can tolerate the harshest conditions, the early days of ecosystem development.  There are usually few nutrients, extreme climatic conditions, and for the animals, few prey to select from.  But these pioneers are adapted to survive in these conditions and over time alter the conditions so that other creatures can move in. 

For the barrier islands, grasses seem to be the plants who do best in the early stages of succession.  Though small shrubs and trees may reach the island, the high winds and salt spray will not allow growth.  There are numerous species of grasses that can live here, the most famous are the sea oats (Uniola paniculata).  This grass can be found on the smallest of barrier islands.  Their fibrous root system runs beneath the ground sprouting new grasses all over.  Their seed heads blow with the wind starting new populations of plants on other locations and the landscape is soon dominated by them.  However, there are other species as well.  Panic grass (Panicum amarium), salt hay (Spartina patens), and beach elder (Iva imbricata) to name a few.  All these grasses can tolerate the wind and salt spray as well as the low nutrient, low rainfall often found on these islands.  They also all have fibrous roots systems that not only connect grasses across the land scape but also trap blowing sand – forming dunes. 

The primary dune is dominated by salt tolerant grasses like this sea oat. Photo: Rick O’Connor.

The dunes closest to the Gulf are dominated by grass due to the higher winds and salt spray there.  These are called the primary dunes and create one of the first habitats on the island for wildlife.  The primary dunes vary in height and how far from the Gulf they range but they do form a wind break for portions of the island landward of the Gulf. 

Here smaller shrubs and plants like seaside golden (Solidago sempervirens) and seaside rosemary (Ceratiola ericoides) can grow.  With less wind their seeds will germinate and survive.  What wind is still there forces the plants to grow in a round shape resembling green sheep on a white field, instead of white sheep on a green field.  My professor referred to them as “beach sheep”.  This area of the barrier island is called the secondary dune and includes other species such as false rosemary (Conradina canescens), square flower (Odontonychia corymbosa), and sandhill milkweed (Asclepias humistrata).  Though they cannot tolerate the high winds as grasses do, they do have to tolerate climatic extremes and low rainfall. 

Small round shrubs and brown grasses within the swales are characteristic of the secondary dune field. Photo: Rick O’Connor

These secondary dunes vary in elevation and can become taller than the primary dunes.  In the low areas between dunes are areas where freshwater water can collect and form ephemeral ponds.  These areas are known as swales and create unique habitats much sought after by some wildlife.  More bog like plants grow here such as water dock (Rumex orbiculatus) and marsh pink (Rhexia nashii) but also includes the carnivorous plants like the sundew (Drosera rotundifolia).  There are many insects who used these ephemeral ponds and many spiders and sundews to take advantage of this. 

Behind the larger secondary dunes, the wind is even less, and the dune wind breaks higher.  Here trees can germinate, if they can tolerate the climatic conditions, and grow.  Though the species that grow out there are some of the same you find on the mainland, here they grow differently.  Barrier island trees tend grow out, not up, to avoid direct contact with wind and salt spray.  And, when they do reach the wind the portion of tree directly facing the wind tends to be stunted in growth, giving it the appearance that someone has “combed” the tree back towards the bay – something they call wind sculpting.  Trees that seem do well in what they call the tertiary dune include sand live oak (Quercus geminata), pine (Pinus sp.), and magnolia (Magnolia grandiflora).  Yaupon holly (Ilex vomitoria) and even cactus like the prickly pear (Opuntia humifusa) and the devil’s joint (Opuntia pusilla) can be found growing here.

Tertiary dunes are some of the largest on the island, with elevations reaching 50 feet or more.  These provide excellent wind breaks from the Gulf and allow the formation of salt marshes along the bay side shoreline.  Marshes are habitats dominated by grass, but these grasses must be able to tolerate periods emersed in salt water, at least at high tide.  Close to the dunes the marsh is dominated by dense stands of black needlerush (Juncus roemerianus).  In some locations within the needlerush marsh are areas of bare sand known as salt pans.  These are low areas within the marsh where water remains when the tide recedes.  These small marsh ponds begin to evaporate in the intense sunlight and the salinity increases to a level where it kills off much of the plant life leaving an area of bare sand.  These salt pans are used by some wildlife on the islands.  Eventually you will reach the waters edge where smooth cordgrass (Spartina alterniflora) grows.  This marsh grass can tolerate water for longer periods than needlerush and supports both island wildlife and estuarine fisheries.

As you can imagine, the process of establishing the pioneer community of grasses on a new, small sand bar, to an island filled with dunes and vegetation takes time – years, decades, maybe centuries – but eventually it will reach what we call the climax community and provides a variety of habitats to support wildlife. 

In part 3 we will begin to look at how animal species colonize the islands as these habitats form. 

Barrier Island Wildlife in the Florida Panhandle Part 1 – The Island

Barrier Island Wildlife in the Florida Panhandle Part 1 – The Island

There are a lot of cool and interesting creatures that live on the barrier islands of Northwest Florida.  The conditions out there require they make changes and adaptations different from what they would do in a more upland or wetland environment.  Some creatures are unique to these beach and dune systems and found nowhere else.  But to begin this series lets first look at the islands themselves. 

The white beaches of the Florida panhandle are primarily quartz. Photo: Rick O’Connor.

The name barrier island comes from the fact that they do serve as a barrier between the open Gulf of Mexico and the mainland of the Florida panhandle, protecting coastal communities from storm surge and waves of the all too frequent hurricanes and tropical storms.  They are basically sandbars formed with sands from the Appalachian Mountains.  There the wind, rain, and temperature erode the granite rock into its mineral components and wash them downstream.  First in the fast-moving mountain streams, then into creeks, into rivers which eventually discharge into the Gulf.  The different minerals settle out based on their size, type, and densities.  Quartz is one of the less dense and is the dominant mineral forming the coastal barrier islands, making them some of the whitest beaches on the planet. 

When these quartz sands reach the Gulf, they encounter longshore currents that are formed from the winds blowing across the open water.  In this part of the Gulf of Mexico these currents tend to move from the east to the west in most cases.  As the rivers reach the passes that connect the estuaries to the open Gulf and the longshore currents move the sand into long thin spits at the mouth of the bays running parallel to the coastline.  In some cases, the sand bars form perpendicular to the coastline, and we call them capes.  Initially still connecting to land, many creatures can venture out on these sand spits searching for food.  Some of the sand spits are very small and seem to come and go as the winds and waves move them.  At times these smaller spits may actually close off the opening into the bay as they once did on Perdido Bay and still do with the Walton County dune lakes.  In other cases, the spits accumulate more sand, become long and can eventually break contact with the mainland forming an island.

At first these islands can be nothing more than sand bars.  Barely above sea level, moving and changing very quickly, sometimes disappearing and reappearing in slightly different locations after storms, such as Sand Island off Dauphin Island Alabama.  In others they are larger, harder to move quickly and may be vegetated so that movement is slower and the island more established, such as Santa Rosa Island near Pensacola.  The creatures on any of these islands will need to be able to adapt to the new conditions.  Some will be able to leave and return the mainland when they need or want to.  Birds are very common on all forms of barrier islands due to the fact they can fly.  In some cases, the distance from the mainland is not a far swim for those who can, such at Indian Pass near St. Vincent Island.  In some cases, the distance may not be as close and the currents between very swift during tide changes making crossing more difficult.  In these cases, the creatures who find themselves on these islands must adapt to the new conditions or risk losing their populations entirely. 

Island conditions can be tough.  There is a lot of wind, and this wind carries salt spray.  There is little cover from the intense sun during the summer months.  Needed freshwater can be hard to find.  Some islands will develop freshwater systems, but others will not.  And then there is the fact that it is an island.  Thus, a finite amount of resources and space for each species, and, at times, fierce competition for those. 

In Part 2 we will explore the different habitats that developed on these islands that available for the different wildlife that exploit them.

Can We Eradicate Cogongrass from the Panhandle Barrier Islands?

Can We Eradicate Cogongrass from the Panhandle Barrier Islands?

Most of us have heard of invasive cogongrass (Imperata cylindrica).  It arrived in the early part of the of the 20th century near Mobile Alabama and has spread across the lower southeast.  It is an aggressive growing grass with serrated leaves and silica imbedded in its tissue.  This makes it very undesirable for livestock and a threat to pastureland across the region – though there are reports of wild hogs consuming it.  It can also invade timberlands where it burns hot during prescribed fires to a point where it can kill the trees you are trying to manage.  It is considered one of America’s worst noxious weeds.

The abundance of this grass across the uplands of the Florida panhandle would indicate that it is far too established for eradication to occur.  But what about the barrier islands?  Is it a threat there and, if so, can it be eradicated?

I personally have seen the plant growing on Perdido Key in western Escambia County.  I know of two locations where it currently resides.  One is on public land, the other private, but we have not conducted a proper survey of the distribution on the Key at this point.  Something we plan to do in 2023. 

I also know it is found along Highway 98 at Gulf Islands Naval Live Oaks near Gulf Breeze in Santa Rosa County.  I am not sure how many records the National Park has of the plant, or how widespread it is on the Gulf Breeze peninsula, nor do I know if it is on Santa Rosa Island/Pensacola Beach.  Again, surveys are planned for 2023.  We obviously need to know this before we can answer the question. 

As of Nov 27, 2022 – there are 82,106 records of cogongrass in the U.S. – all are in the lower southeastern portion of the country.  There are records as far north as North Carolina and as far west as the LA/TX line.  Alabama is completely covered, as is much of the Florida panhandle. 

As far as barrier islands, it is found on each of those within the state of Mississippi (10 records total).  There are eight records on Dauphin Island AL, 16 on Ft. Morgan peninsula, eight in Gulf Shores AL proper, and nine in the Orange Beach AL area. 

In Florida there are five records on Perdido Key proper, 13 more along the north shore of Big Lagoon, 125 along coastal NAS Pensacola, seven at Ft. Pickens on Santa Rosa Island in Escambia County, seven more at Naval Live Oaks in Gulf Breeze, six on Eglin property on Santa Rosa/Okaloosa Island, and 32 on Okaloosa Island between Ft. Walton and Destin.  Here the western panhandle islands end.  Between Perdido Key, Santa Rosa, and Okaloosa Islands proper – there are 50 records of the grass. 

Along the coast between Okaloosa Island and Shell Island in Bay County, there are 44 records.  There are no records on Shell Island itself but there are 86 records on Tyndall AFB.  There is one record on Cape San Blas in Gulf County, one on St. Vincent Island and another along Highway 98 just west of Apalachicola in Franklin County.  The barrier islands between Apalachicola and Bald Point have no records. 

Based on this, the islands at the far eastern end of the panhandle should easily be able to eradicate these plants.  The islands on the western end have more work to do, but a total of 50 records ON THE ISLANDS should be doable.  This, of course, is based on the number of records being accurate, and I am sure they are under reported. 

Step 1 – conduct surveys

As with beach vitex, the first step is to accurately survey our islands to determine how widespread the problem really is, and then develop a management plan to possibly eradicate them. 

Step – management

There are currently no known biological controls for this invasive plant. 

Repeated disking and deep plowing have been shown to be effective in agricultural lands where it is possible to do.  Mowing and/or burning when not in seed AND THEN CHEMICAL treatment has also had success.  This should be done in the fall.  Mechanical management alone has not been effective. 

The chemical active ingredients of choice are glyphosate and/or imazapyr.  As mentioned in the beach vitex article, imazapyr has a much longer soil activity and replanting cannot be achieved for several months.  Replanting with native plants has been found to help control cogongrass but to do so quickly would require the use of glyphosate.  In all studies, one chemical treatment was not enough. 

This is a very tough noxious weed and early detection – rapid response (EDRR) is crucial at eradicating this species.  We will begin Step 1 in Escambia County this year.  If there are groups in other counties interested in doing the same, let us know and we will help where we can (roc1@ufl.edu).   

Weekly “What is it?”: Coastal Plain Honeycombhead & Gulf Coast solitary bee

Over my years of leading people on interpretive trail hikes, I have learned it is particularly important to know the names of whatever happens to be in bloom. These flowers are eye-catching, and inevitably someone will ask what they are. In fact, one of my favorite wildflower identification books is categorized not by taxonomy, but by bloom color—with a rainbow of tabs down the edge of the book for easy identification.

In our coastal dunes right now, several plants are showing off vibrant yellow blooms. Seaside goldenrod, coreopsis, and other asters are common. Rarer, and the subject of today’s post, is the Coastal Plain Honeycombhead (Balduina angustifolia). It has bright yellow flowers, but often gets more notice due to its unusual appearance when not in bloom. The basal leaves are bright green and similar in shape and arrangement to a pine cone or bottlebrush (albeit a tiny one), sticking straight up in the sand. The plants are typically found on the more protected back side of primary dunes or further into secondary dunes, a little more inland from the Gulf.

The plant plays a special role in beach ecology, as a host plant for Gulf fritillary butterflies and the Gulf Coast solitary bee (Hesperapis oraria). The bee is a ground-dwelling pollinator insect that forages only in the barrier islands of Mississippi, Alabama, and Florida. The species is currently the subject of a University of Florida study (they’re out at Ft. Pickens right now), as the endemic bee’s sole source of nectar and pollen is the honeycombhead flower. As of publication date, no bee nests have been discovered. Researchers are interested in learning more about the insect’s life cycle and nesting behaviors to better understand and protect its use of local habitats. Based on closely related species, it is believed the Gulf Coast solitary bee builds a multi-chambered nest under the soft sands of the dunes.

While the honeycombhead plant is found in peninsular Florida and coastal Georgia, the bee has been identified only in a 100 km² area between Horn Island, MS, and St. Andrews Bay, FL. Luckily for the bee, large swaths of this land are preserved as part of Gulf Islands National Seashore and several state parks. Nonetheless, these coastal dune habitats are threatened by hurricanes, sea level rise, and development (outside the park boundaries). Due to its rarity and limited habitat, a petition has been submitted to the Fish and Wildlife Service for protection under the Endangered Species Act.unfilled heart 0

Wildlife on Our Barrier Islands in August

Wildlife on Our Barrier Islands in August

It has been a few months since we have posted an article on the changing wildlife over the course of a year on our barrier islands.  I took the month of June off and just could not schedule a hike in July.  But it is now August, and we DID get out this week. 

This is no surprise… it is hot and humid.  I think everyone has noticed this.  We are also in the rainy season.  Based on the NOAA site I track, we are currently at 45.73” for the year.  This is an average of 6.53 inches a month which would lead us to an annual amount of 78” if we keep that pace.  This would be another wet year. 

This rainfall does a lot to cover up tracks I am looking for.  It will spook some creatures into hiding waiting out the weather, but there are plenty of others who enjoy the rain and are more on the move. 

This rainbow indicates how wet this part of the year can be on our barrier islands.

Today I took my grandson with me on the hike.  He loves the outdoors and reptiles and amphibians especially.  We began, as we always do, walking a section of the Gulf beach to see what we could see. 

We immediately encountered a sea turtle nest.  I understand that it has been a good year for sea turtles in our neck of the woods.  The turtle patrol had roped this one off, but I did see human footprints inside the roped section.  We encourage people NOT to do this.  Compacting the sand can be a problem and if they hatch and detect vibrations they may not emerge.  It is cool to see one, but do not go past the roped section. 

The sea turtle patrols mark the nest with stakes and rope. People should not enter beyond the roped section.

We always search the wrack line for cool things and today we ran into a few.  First, there were hundreds of small dead anchovies washed ashore.  I am not 100% sure what happened but I am guessing a strong storm came and washed them in.  Anchovies are a great source of food for many marine fish and these dead ones will certainly feed the numerous birds and ghost crabs that live along the shores.  Anchovies play an important role in the ecosystem and, even though these were dead, it is nice to see them. 

We did find several catfish heads.  Saltwater catfish are not prized by Gulf fishermen.  Many prefer to cut their heads off and leave them on the beach.  The thing is that this does little to deter the population of this unpopular fish and the spines can be dangerous for beach combers walking barefoot.  But the ghost crabs usually collect and feed on them. 

The serrated spines of the hardhead catfish are still on this discarded head. beach combers should be careful when walking near these.

We also found a few comb jellies.  These are members of a different phylum (Ctenophora) than the classic jellyfish (Cnidaria).  They lack stinging cells and move using their rows of ctenes (cilia) that resemble the bristles of a comb as you run your finger over it.  This is where it gets its common name.  They do produce blue colored bioluminescence in the evening and are beautiful to watch.

Comb jellies do not sting and they produce a beautiful light show at night.

As we crossed the road and enter the dunes, I explained to my grandson how the foredune is dominated by grasses.  These plants can tolerate the strong winds off the Gulf and the salt spray as well.  On the other side of the road, you enter in the secondary dune field.  This region is a mix of grasses and small shrubs, which can grow due to the primary dunes blocking some of the strong Gulf winds. 

Today we saw several species of flowers in bloom.  Different plants bloom at different times of the year and it is neat to see who is blooming at different times.  The low swale areas were full of growing plants and flowers.  There were plenty of sundews and ground pine.  Some standing water but much was dry.  We did find a plant in one of the wet swales I did not know.  I am listing it here as redroot but I am not confident in that identification and would love if someone who knows it will share its name.    

This once barren flat of sand is now full of grasses and flowers.
This common secondary dune plant is what I call “square flower”.
I am not sure what type of plant this is. I am calling it red root and hope someone with a better identification will let us know.

There were numerous tracks of armadillos but little else from the animal world.  Again, the rains wash them away.  The milkweed was still blooming awaiting for the now listed monarch butterflies.  And the beach side rosemary was releasing its characteristic odor that says “Pensacola Beach” to me.  The plants looked great and seem to enjoy the rain.  FYI – we did get rained on during the hike, but not too bad.  We had seen the parasitic dodder earlier in the year and the vine was still evident in August. 

Though many of the tracks were washed away in the rain, some are still there. The animals are still moving.
We first saw milkweed blooming in April. Here in August some are still in bloom.
Seaside rosemary is one of the more aromatic plants on our barrier islands.
Dodder is a parasitic vine often called “Love Vine”.

In the tertiary, or back dunes, is where I always hope to find tracks or animals of some kind.  Today there was little evidence of any.  There were raccoon tracks moving along the edge of tallest dunes and along the trails leading to Santa Rosa Sound.  But not much else.  The pines were bearing their cones and the sweet bay magnolias had their young blossoms forming.   

Many of the pine trees growing in the back dunes are now producing cones.
Sweet bay is in the magnolia family and produces a similar blossom.

One species my grandson did not enjoy were the numerous devils’ joints.  This branching cactus has very sharp spines and were all over the back dunes.  We had to stop and remove them several times.  He definitely wanted to find a different way back! 

The Devil’s Joint is not one of the more pleasant plants to encounter in our dunes. We encountered plenty today!

We did reach the Sound and walked along its edge towards the old fish hatchery.  He saw TONS of fish (as he put it) and the grass looked thick and healthy.  We did get to explore and talk about the old fish hatchery.  And then headed back towards the Gulf and our truck. 

I think we got started a bit late to see a lot of the wildlife.  This time of year, they will be hunkered down somewhere early in the morning to prepare for another hot day.  With the overhead clouds I was hoping to see some movement, but we did not.  We will try earlier in the day in September. 

I hope you get out and explore our barrier islands.  They are fascinating places.  But plan to get into the water this time of year.  We did.  It was hot.  We went snorkeling and saw numerous pinfish, a flounder, and snapper, and a nice sheepshead.  This is a good way to spend the hot parts of the day.  Let’s see what September may bring.
