Natural Notes: Birds and Habitats of the Florida Panhandle

Introduction
This spring I decided to take a break from Chicago's icy and cold weather and venture down to the Florida Panhandle (figure 1).  It was perfect timing for seeing migratory birds (and resident birds) making their way back up north. Florida in general is well known for its bird life, as its warm and swampy landscape provides a haven for birds and other wildlife.  Most people are accustomed to thinking of Florida as a landscape of high rise condominiums, tacky beach-themed restaurants, and swaying coconut trees.  The panhandle of Florida, however, looks much different overall than the southern part of the state.  For one thing, it is over 300 miles further north than the near-tropical regions of Miami and the Keys.  Secondly, outwash from the Appalachian Mountains and accumulated marine deposits allow for the presence of hills and even cliffs in this region of the Sunshine State.  And you won't find any coconut trees (Cocus nucifera) here, as wintertime temperatures can sometimes drop below freezing with an even colder windchill.  The Florida Panhandle is truly more of a subtropical environment.

That being said, the pandhandle of Florida does have a lot of similar vegetation communities, and this diversity makes the entire region a 'bird heaven'! During my trip my friends and I explored several different habitats in the numerous protected areas across the Florida Panhandle.  Please note that this blog post does not provide an official list of all of the plant communities found or described in this region.  

Some Common Habitats in the Florida Panhandle
Being along the gulf coast, one of the most common habitats we explored was the coastal salt marsh community (figure 1).  These shoreline wetlands are often dominated by Saltmarsh Cordgrass (Spartina alterniflora) as well as various species of rushes (Juncus spp.).

The vegetation in this community is highly tolerant of salty water, as ocean water mixes with fresh water to form a salt-fresh mix known as brackish water.  Many species of crabs and mollusks inhabit these areas, making it a prime destination to see a diverse array of birds that feed on the plant and animal material found in saltmarshes.  

One of my favorite areas we explored, although not as diverse as far as birds are concerned, were the palm hammocks (see figure 2).  Saw palmetto (Serona repens), a low-growing shrub palm, is the dominant understory plant, 20-60 foot tall sabal palms (Sabal palmetto) grow at mid-level in the canopy, and slash pines (Pinus elliotti) tower above the palms in the overstory.

Viewing the palm hammocks almost feels like looking into the past at the Jurassic period when the last major group of dinosaurs ruled the earth and monocots (primitive flowering plants) like palms and sedges dominated the vegetation communities.  

Of course, the beach and sand dune environments make the Gulf Coast a famous vacation destination (see figures 3 and 4).  Ghost crabs tunnel through the sand hiding from beach-goers and then come out at night in vast numbers to feed.  Sanderlings (Caladris alba) run up and down the swash zone of the beach (where the waves level out onto the sand) probing for tasty mollusks and crustaceans (see figure 5).  Dunes composed of bright-white quartz-based sand have sparse vegetation with sea oats (Uniolia paniculata) and occasionally even a prickly pear cactus (Opuntia sp.) (figure 6).

The dune areas were also covered with ample amounts of lichen, a mix of algae and fungi that thrives on nutrients from the air.  Lichens are visible in figure 6 as a crusty material growing around the cactus.  

In between the saltmarshes and beach areas, and out of direct wind and salt spray, are the maritime forests.  Southern Live Oak (Quercus virginiana), which is also found in a stunted form along some of the sand dunes, are often fond here as are Lobolly pines (Pinus taeda) and sometimes longleaf pine (P. paulstris).  Spanish moss (Tillandsia usneiodes), which is actually a bromeliad in the same family as pineapple, hangs from live oaks and other trees as an epiphyte, using nutrients and moisture from the air to photosynthesize (see figure 7).

Further inland, the landscape consists of southern hardwood forest and longleaf pine barrens, but we did not explore these areas in depth.  

Something I noticed with all of the plant communities we went through was the active use of prescribed burns by land management agencies.  A prolonged drought in an area with lots of pine trees shedding needles makes the Panhandle very vulnerable to wildfires.  Small, controlled burns allow excess leaf litter (otherwise great fuel for a wildfire) to be burned up while maintaining a diverse native plant community.

I would like to thank my colleagues and friends Jessica Orlando and Kathleen Mahoney for chauffeuring me around the Florida Panhandle and rekindling my naturalist spirit.  I would also like to thank my aunt in-law Diana Brooks for taking me to one of my Grandmother's favorite spots:  the Birmingham Botanical Gardens.
