Beginning this month we will be posting a series of natural resource articles high lighting Florida’s Panhandle. The photographs and hikes presented in this series are from Escambia and Santa Rosa counties but the same natural places can be found anywhere between the Perdido and Apalachicola Rivers. We hope our readers will visit these places and DISCOVER FLORIDA’S PANHANDLE on their own. This year we will begin at the Gulf of Mexico and visit our BARRIER ISLANDS. We will visit the same location on Santa Rosa Island in Escambia County each month over the course of a year. During this series we should see how things change each season and learn more about our natural places.

Here is the Gulf of Mexico. The northern Gulf is primary sand but their are areas of hard bottom that provide habitat for many of our commercial important fisheries. 450 feet off the shore from this photo is an artificial reef placed by Escambia County for residents and visitors alike to explore. These reefs attract a variety of reef fish and sea turtles and are great for wildlife viewing. Notice how low the sun is in the sky on this winter morning. The shortest day of the year was December 21 (when the sun was it’s lowest) and will be “climbing” as this series continues. Many beach residents use this as their clock!
Our barrier islands are considered the “world’s whitest beaches” and this is because of the high amount of quartz deposited here. In this photograph you can see the water is farther from shore than usual. This is due to the strong north winds blowing water offshore; this happens every winter – but provides feeding opportunities for shorebirds. The sand fencing is used by many of our counties to “kick start” dune restoration.

Beyond the primary dune on this portion of the island you will find low areas known as swales. These “depressions” will fill with water during rain events and provide much needed freshwater for the organisms who live out here. Barrier islands are xeric environments (meaning “desert like”) and freshwater habitats are very important for many creatures. Some of these ponds are ephemeral (meaning non-permanent) and dry up during some periods of the year.

Where the primary dune and swales end the secondary dune fields begin. Because of the primary dunes there is less wind and salt spray which allows different species to take root. The secondary dunes are often identified by their small round shrubs – such as goldenrod and beach heather. These larger plants will trap larger amounts of sand producing larger dunes. On the secondary dunes I usually find lots of tracks. Identifying tracks is difficult (especially in soft sand) but fun. Most of what I saw this winter day were mammals. Raccoons, opossums, and armadillos are very common. Skunks were once common but have been scarce since the hurricane years. Below are tracks of a canine. Many people bring their dogs to the beach but coyote and fox are also found here. These tracks measured about 3.5″ and more round than triangle shaped; suggesting this is a dog.

This secondary dune supports a saw palmetto. Many forms of wildlife depending on these shrub areas.
These unidentified canine tracks are probably of a dog; though coyotes are on our islands
Beyond the secondary dunes are the largest dunes on the island, some measuring over 50′, these are the tertiary dunes. With the secondary dunes blocking wind and salt spray larger plants still are allowed to grow. Here we find actually trees; pine, live oak, magnolia to name a few. With the loss of primary and secondary dunes the tertiary dunes are exposed to the wind and salt spray of the Gulf side, which puts them at risk. This is why sea oats and primary dunes are protected in most counties.

Tertiary dunes are the largest dunes on the island; some reaching over 50′.
Tertiary dunes support trees such as this magnolia and yaupon holly.
The large field of tertiary dunes blocks enough wind that forests and salt marshes can establish themselves on the back side of the island. Here the diversity and abundance of wildlife increases. We have found not only the mammals already mentioned but snakes, freshwater turtles and terrapins, and a variety of birds. This winter day I found several small woodland and mocking birds. Some of our islands have deer and alligators.
From atop a tertiary dune you can view the maritime forest, salt marsh, and sound beyond. Photo: Rick O’Connor
Within the maritime forest you will find a variety of plants and animals.
Holly’s are famous for having the bright red berries around Christmas time. Here in January the berries are still found on some of them.
Between the maritime forest and the salt marsh you may find freshwater ponds. Like the swale ponds, these places are great places to find wildlife. Though I have not seen them in many years I have found alligators in this area. These ponds support populations of amphibians and small fishes.
This freshwater pond has bull minnows, amphibians, snakes, and – in the past – alligators. Photo: Rick O’Connor
With the dunes blocking offshore winds trees can grow much larger on the back side of the island; like this live oak.
This pond supports a stand of green algae which supports many of the aquatic animals that visit here.
On this winter day I primarily saw bird life. The air temperature was 39 F and the wind was out of the north. Many of the mammals move at night and the reptiles, being cold blooded, were hibernating somewhere; the bird life however was pretty active. Many woodlands birds were out feeding on seeds and berries, herons and egrets were in the marsh hunting fish in the shallow waters, and shorebirds were picking through the beach wrack and some were diving.

This unusual drag was found between the salt marsh and the sound side shoreline. It looks like a turtle crawl but at his time of year more probable something being dragged by something.
Armadillo tracks can be identified by their “tail drags”.
Salt marshes are one of the most productive systems on earth; and the target for another FLORIDA’S PANHANDLE series. Crabs, shrimp, mollusk, worms, terrapins, fish, and birds are some of the wildlife that call this place home – and maybe we will find some as this series continues into the warmer months. Today I found pelicans, herons, and egrets here eating.

The muck of a salt marsh. This rich organic mud is very loose and the hiker can quickly sink! Notice the tracks of a predator.
Notice the low water levels typical of winter. This congregates fish into smaller pools and makes it easier for birds and mammals to catch them.
The Sound side of the island has wind but less wind than the Gulf side. The wave energy here is also lower supporting seagrass and oyster communities. Like the marsh these places are very productive; though all I really saw moving on this cold winter morning were the birds. There are two species of seagrass common to our sounds; turtle grass and shoal grass. However there have been reports of more tropical species appearing. We may find some when the water warms up. These waters support at least 100 species of fish and many invertebrates we enjoy eating.
The darker areas in the water are seagrasses. Photo: Rick O’Connor
I found this along the shore last winter. These are cannonball jellyfish.
This is a sea nettle. This species of jellyfish has a more painful sting. I only saw one of these today but saw several cannonballs.
People find this “sea foam” frequently when they visit the beach. It is formed when the winds pick up and there are nutrients in the water. It was up and down the beach today.
It is not uncommon to find dead fish along the shore after a hard freeze as we have had in recent weeks. When it warms these dead fish will attract scavengers including cottonmouths. Maybe we will see one later in the year.
There was very little trash on the island today but it was there. These pieces of debris can cause serious problems for coastal wildlife. We will discuss this issue more as this series moves on.
Well, for January we found the beach to be cold and windy. Very little wildlife was out to be viewed other than birds and the numerous tracks in the dunes, but as the temperatures warm we will see more. Take some time to visit our barrier islands and enjoy them. Until February.
The commercial and recreation stone crab season has opened! Now is the time to enjoy local stone crab claws. Whether you catch them yourself or buy from a local seafood market, the delicious meat is worth the effort and cost.
There are 2 species of stone crab found along the Gulf Coast. The Florida Stone Crab is found in the southern part of the state, while the Gulf stone crab is found from the Western Panhandle to Mexico.
Stone crabs can be found in holes along oyster reefs, rock jetties and shorelines lined with riprap. Adult stone crabs feed on oysters, mussels, clams, worms and other crustaceans.
Recreational harvesters must have a valid Florida Saltwater Fishing licence and are limited to 5 traps that meet the specifications set by FWC. Maximum trap size is 2″x2″x2″ and traps must have a degradable panel that is 5 ½ inches by 3 ½ inches and is made of cypress or untreated pine slat no thicker than ¾ of an inch. These regulations are to protect marine life from ghost fishing, when traps are abandoned or lost.
The recreational bag limit is one gallon of claws per person or 2 gallons per vessel or which ever is less. Only one crab claw should be taken. Crabs are released alive with one claw intact and are able to feed and defend themselves, which allows the crab to be caught again in the future. The claw that was removed will grow back each time the crab molts. Claws must be 2 3/4 inches in length from the tip of the claws to the first knuckle.

Watch the following video from FWC to learn how to harvest a claw correctly without injuring the crab.
Stone crab claws can be enjoyed cold or hot, in the shell or peeled and in many different dishes. Enjoy stone crab claw meat with mustard dipping sauce, in soup and bisque, crab cakes, salads, etc. Many recipes can found on-line.
Use a butter knife, mallet, claw cracker or hard spoon to crack the shells. If you want to prevent shell from flying around, cover the hand that will hold the claw or the surface that the claw will be cracked on with a dish towel. Gently tap the sections of the claws, until they are cracked, be careful not to break the shell into the meat.
Check out this video to learn how to crack stone crab claws:

Spring is a dynamic time for wildlife. If you enjoy watching nature, now is a fantastic time to get outdoors to see some interesting activity. March is also one of the best times of year to do some active management on your property to enhance the habitat you provide for wildlife.
Purple martins select nest sites during February-March in the Panhandle, so now is your last chance to make martin housing available. Photo by Sarah Friedl.
Because of its position just north of the Gulf of Mexico, Florida is the first landmass where many exhausted birds can rest after migrating northward to the U.S. from South and Central America. The strenuous northward migration is now underway for many species of birds. That means this is one of the most interesting times of year to visit your local natural area with a pair of binoculars. A trip to St. Marks National Wildlife Refuge or your nearby State Park or Wildlife Management Area could result in a glimpse of several migratory species that are rarely seen in the area.
Purple martin scouts began their migration from South America to the Panhandle nearly four weeks ago. If you have purple martin housing and have not yet cleaned out last year’s nesting material, now is your last chance to do this. Wash out your housing with soap and water. If you take your martin housing indoors during the fall and winter to protect it from harsh weather or if you plug the entrances to prevent use by other species, don’t wait any longer to make your housing available to martins or you’ll miss out on attracting them this year. Older martins remain extremely faithful to the exact same nesting site, so will want to return to the housing you provided them last year. In contrast, yearling martins that hatched last summer tend to return to the same area they were born in Florida about 4-6 weeks later than the older scouts. These yearling birds are generally the ones who adopt new housing and start new colonies. Therefore, this week is the ideal time to put up new purple martin housing in the Panhandle.
Eastern bluebirds are resident all year round, but March is when they begin nesting in the Panhandle. Because bluebirds have a habit of nesting several times each year, it is possible that birds will adopt new houses erected later in the spring. However, the sooner you make new bluebird houses available, the greater the chances you’ll attract nesting birds. When deciding where to locate new bluebird houses, remember that bluebirds are territorial and will not let another bluebird nest within ~100 yards of a nest site they’ve already chosen.

Deer grazing test plots at the NFREC in Quincy. Food plots can benefit deer year round, not just during hunting season.
To the chagrin of hunters across the panhandle deer season has drawn to a close. As the days lengthen and temperatures begin to climb, many of the area’s outdoorsmen (and women) shift their focus to a more aquatic nature. However, those sportsmen, who will place a premium on antler size in the fall, should not neglect the nutritional needs of the deer herd during the spring and summer months.
There is a well-documented correlation between deer nutrition and antler growth. Antler growth is suppressed when adequate nutrition is not available. Antler growth requires a large amount of energy and protein. The energy requirements for antler growth can generally be met by the deer’s natural environment. However, some natural environments may not supply enough protein to maximize antler growth. Nutrition is only one of several factors effecting antler growth but it is perhaps the easiest of those factors to alter.
Source: Mississippi State University, Forest & Wildlife Research Center http://www.fwrc.msstate.edu/pubs/antler.pdf
As with all animals, a deer’s nutritional demands change over time. The suppressing effect of insufficient protein in the diet is most evident in younger bucks. This is because the bodies of immature deer are still growing. The processes of growth and development demand protein. When antler growth is added to the equation the protein demand of a young buck can easily exceed what is provided by it natural environment. Research indicates that young, growing deer during antler development need a diet that is approximately 16% crude protein in order to maximize antler growth. Mature bucks can maximize antler growth with as little as 10% crude protein.
Planting and maintaining warm season food plots is a good way for a deer herd manager to help prevent any nutritional limitations to antler growth. Food plots are often thought of in terms of their ability to attract deer to a specific location during hunting season. However, if properly utilized food plots can have a lasting positive effect on an area’s deer herd and other wildlife. Follow the links for the basics on food plot establishment and soil fertility management.
If your goal is to increase the amount of protein available to the deer herd then legumes are your best bet. Some warm season legumes that do well in the panhandle include Aeschynomene, Alyceclover, Cowpeas, Soybeans, Lablab, and Perennial Peanut. It is important that you select species and varieties that are suited to the conditions (especially soil properties) of the area you intend to use them. It is also recommended that you plant a variety of species in any food plot.
The species listed vary in terms of grazing tolerance and recommended planting technique. Contact your county’s extension office for more details.
Legumes provide high amounts of protein to deer and other wildlife because they contain relatively high amounts of nitrogen. Due to a symbiotic relationship with a specific type bacteria, legumes are able to utilize atmospheric nitrogen. Other plants are dependent solely on soil nitrogen. To ensure that the proper bacteria is available to the legume it is important to inoculate legume seeds prior to planting. Inoculants are available through most seed dealers. Be sure that you get the proper inoculant for the species you are planting. Aeschynomene, Alyceclover, and Cowpeas all require the inoculant for the cowpea group. Soybeans and Lablab each have a species specific inoculant. Perennial Peanut does not require inoculation because it is not planted from seeds. Additional information about inoculants, planting techniques, and fertilization is available from your county’s extension office.
Planting food plots does not guarantee any additional antler growth but it is one way to help alleviate a possible limiting factor. Habitat improvement and additional available nutrition can benefit the entire ecosystem. If you want to get the most out of your property, in terms of deer production, it is important to provide the deer what they need all year long, not just during hunting season.
March 5th: Torpedo Grass (Panicum repens) & Hydrilla (Hydrilla verticillata)
Torpedo Grass Photo Credit: Graves Lovell, Alabama Department of Conservation & Natural Resources, www.bugwood.org
Torpedo Grass: Torpedo grass (Panicum repens) is an invasive weed that invades lawns, flowerbeds, landscapes and wetlands. Even if introduced into a small area, this weed can rapidly spread to become a monoculture and crowd out native vegetation. Its name is derived from the hard, sharp point of the rhizome that looks like a torpedo.
Native to Africa and Asia, Torpedo Grass was introduced to the United States around 1876, primarily through seed used for forage crops. The real infestation came in the early part of the 20th century when the USDA imported and distributed seed for planting pastures as forage for cattle. It proved to be inferior for use as a forage crop. Now it is found in the Gulf South from Florida to Texas and in other coastal areas around the world.
Torpedo grass is nearly impossible to completely eliminate, so management of it is not a matter of how to get rid of it completely but instead how to prevent it from taking over an area. The only way that this can be accomplished is with repeated and frequent efforts. You will have to scout regularly and any time torpedo grass is seen, promptly take action. Prevention of torpedo grass centers on removal of the entire plant, as the plant can regrow from fragments left behind in the soil. There are few control options for torpedo grass. Options will depend on its location and surrounding vegetation. For management in lawns please refer to http://edis.ifas.ufl.edu/ep387 for specific herbicide controls based predominate lawn species. For management of invasive species in natural areas, refer to http://edis.ifas.ufl.edu/wg209 for a comprehensive list of species and their controls. As always, refer to instructions on herbicide label to ensure proper usage.

Hydrilla:Hydrilla is a perennial submerged plant that grows in dense mats up to the surface of freshwater habitats, including ponds, lakes, springs, and rivers. Growing at the rapid rate

of an inch a day and up to 25 feet long, hydrilla shades out beneficial native plants and clogs waterways, preventing flood control, boating, and fishing. In dense populations, the plant can alter oxygen levels and water chemistry and survive in a wide variety of nutrient conditions, sunlight availability, and temperatures.
Originating in Asia, it was introduced to Florida (likely through Tampa and Miami) in the 1950’s as part of the worldwide aquarium trade. Hydrilla has become a very expensive problem for the state. Millions are spent annually on chemical and mechanical treatment simply to maintain the plant. Adding to the problem is the fact that it is still available commercially, even though it has been placed on the US Federal Noxious Weed List. In the United States, the plant is found as far north as Connecticut and west to California and Washington.
Methods of control include mechanical harvesters and chopping machines (although fragments of hydrilla left in the water can regrow), introduced insects and fish (particularly the Chinese grass carp), aquatic herbicides, and lake drawdowns. Hydrilla is often transported from one body of water to the other by unknowing boaters moving fragments of the plant left on boats, trailers, or live wells, so learning to identify the plant and cleaning boats before leaving the ramp are helpful in prevention. Visit the Extension Hydrilla IPM site for more helpful tips.
