The Florida Panhandle is fortunate to have an abundance of salt marsh habitat fringing many of our coastal environs. Although this habitat may not receive the appreciation it deserves by those seeking a white-sandy beach, it is intricately linked with many of the natural treasures we are blessed with. Salt marshes occur in the ecotone where the land connects with the salty water and they are occupied by a special assemblage of salt-tolerant, hydrophytic plants that provide benefits on many levels. Literally, levels that stretch vertically from the substrate to the tops of the grasses, and horizontally as the plant species are arranged into different zones depending on water depth. These habitats typically occur in coastal areas of lower wave energy, where the marsh plants can establish and thrive. Often this is in our bays and estuaries that are afforded some protection from storms that blow in from the open Gulf. Looking from the land outward, the classic salt marsh vegetation zones begin with the high-marsh which only gets inundated during extremely high tides. This area is dominated by a grass called marsh hay (or salt meadow) cordgrass (Spartina patens) that grows in wiry-leaved clumps. You can also find salt grass (Distichlis spicata) which has shorter, flat leaf blades that project from the stem at a distinctive angle. The mid-marsh zone is typically in and out of the water on daily tides and is usually dominated by a species of rush called black needlerush (Juncus roemerianus). The low-marsh grows in an area that stays under water much of the time and is inhabited primarily by smooth cordgrass (Spartina alterniflora) in our Gulf Coast marshes.
Ecologically speaking, you might deduce that salt marshes are not incredibly diverse, at least as far as plant species inhabiting them. However, the structure, cover and vegetative food components that are available here support a tremendous assortment of animals; some that we depend on for seafood, some that our seafood depends on in a complex food web, and others that are simply a pleasure to know about. Many utilize these grassy nearshore areas during the juvenile portion of their life cycle. Baby crabs, shrimp and fish find many of their needs met here. Just spend a few minutes quietly observing in this habitat and you’ll be amazed when you notice the baby mullet, spotted sea trout, redfish, killifish, fiddler crabs, and a host of other creatures going about their “marshy” business. It is also a special treat to conduct a nighttime investigation with a flashlight here. Just wear protective shoes as oysters often grow in these places.

One group of animals that depends on this habitat is our coastal bird life. In fact, there is a subset of birds here that has been dubbed with the title “secretive marsh birds,” because they rarely come into the open where people can see them. This group includes several species of rails, bitterns, gallinules and others. Scientists have been concerned about declines in many of these species so standardized methods have been developed to survey them using broadcast recordings to elicit vocalizations that can be counted by researchers. There are also many not-so-secretive marsh birds that find their needs met in our marshes. Harriers visit during the winter months, blackbirds and sparrows find nesting cover here, and egrets, herons and kingfishers dine on the fish and invertebrates that are abundantly plentiful during key stages of their nesting and chick raising cycles.
Last but not least (in my book) are a couple of reptiles that can be found in our saltmarshes. The gulf salt marsh snake (Nerodia clarkii) uses the marsh for cover and to find its preferred diet of small fish, crabs, shrimp and other invertebrates. They spend their days generally hiding under debris, being more active at night. They can be recognized by their four lengthwise yellowish stripes and the fact that you aren’t likely to find another snake in the saltmarsh. However, I have seen a cottonmouth or two spending time here, so be careful. The other unique reptile we can find in select areas of our marshy coastline is the ornate diamondback terrapin (Malaclemys terrapin macrospilota). These charismatic coastal turtles are sexually dimorphic, with males only reaching about five inches and females growing to around eight inches. The yellow centers on the dark scutes of the back are a definitive identification feature, along with very pale gray skin that may be speckled with black dots. Terrapins feed primarily on mollusks and crabs and use the adjacent upland areas for laying their eggs. Terrapins have suffered dramatic declines throughout their range because they are attracted to bait in crab traps and can be trapped and drowned. There is a simple conservation solution though. If you are in an area that terrapins frequent you can install a rectangular exclusion device in your trap funnels that will keep out terrapins but let crabs through. Awesome invention!
Ornate Diamondback Terrapins Depend on Coastal Marshes and Sea Grass Habitats
Take some time to visit our incredible coastal marshes and appreciate the diversity of life they provide us, along with the most profound serenity of any beautiful, wide-open vista that you’ll ever find anywhere.

The Annual Tupelo Honey Festival will be held on Saturday, May 21st from 9 AM – 4 PM at Lake Alice Park in Wewahitchka. It’s an exciting event, and your chance to take part in this local delicacy. Area honey producers will be on hand, selling their honey in a variety of sizes. There will also be food, art & crafts, and live music.
For decades, tupelo honey has been synonymous with Gulf county. The pollen from the tupelo gum tree (Nyssa ogeche), produces some of the finest honey in the world. The common name “tupelo” is derived from language of the Muscogee Nation, also known as the Creek Indian Nation. The meaning of the word is “swamp tree”, as this tree flourishes in areas of wet soils and seasonal flooding. Gulf county, especially in the Dead Lakes and Apalachicola river region, provides prime habitat for one of the largest tupelo forests on earth.
The tupelo pollination process kicks off during April. The tupelo bloom begins to form as a small bud. Within a few weeks, the bud explodes into a cluster of many nail or spike like attachments. At this point, honeybees begin to descend and capture the pollen.

The tupelo bloom season lasts from approximately mid-April to the end of May. This is an anxious time for beekeepers. Tupelo blooms are very temperamental and delicate in nature. For this short period, beekeepers hope for little wind or rain and no cold temperatures, as any of these factors can decimate tupelo honey production. Regardless of seasonal impacts, the demand for Gulf County’s tupelo honey never subsides.
A bonus to honey’s great taste, is the medicinal value. Honey has been used for medicinal purposes throughout time and cultures. Ancient Egyptians used honey in the embalming process, wound dressing and treatment for burns. Honey can be used as an antimicrobial agent. This is mostly due to low concentrations of hydrogen peroxide produced naturally from sugar compounds. Honey contains large amounts of sugars, approximately 97%. Most of the sugar content is glucose and fructose. Honey also contains smaller amounts of vitamins and minerals.
The color of honey is a factor when grading content. Generally, a darker honey will have a higher concentration of polyphenols. This means the honey is higher in antioxidants and anti-inflammatory properties. Exposure to area honey has been thought to help people who suffer from area specific seasonal allergies. However, there is no consensus among the scientific community to support the claim. Though there is research supporting honey as medicinal purposes, please consult with your physician before using as a medical treatment.
Enjoy tupelo honey and see you at the festival!

Summertime and swimming at the beach just go together naturally in Florida with our state’s more than 1,000 miles of coastline. Many fond memories are created along these salty margins and the Panhandle region of the state has some of the top-rated beaches in the world. It is a great place to experience a relaxing, cool dip in the Gulf of Mexico on a balmy summer day. One thing to be aware of though is the possibility of an encounter with one of the Gulf’s “stinging” inhabitants and what to do if this occurs.

There are actually several different organisms that have the capability to sting. This is primarily their mechanism for capturing food but it may also serve to deter predators. Most belong to a group of organisms called “Cnidarians,” which includes the jellyfish. Most jellyfish are harmless to us and are important food sources for many other marine creatures, including some sea turtles, fish and even other jellies! Some species are even dried, shredded and eaten by humans. However, there are several types of jellyfish that will inflict a sting when brushed against and some that are actually a serious hazard. Keep in mind that people also react differently to most venoms, exhibiting varying degrees of sensitivity. The most dangerous types include some of the box jellyfish species (visit HERE for general map of worldwide jellyfish fatalities), and the blue-colored Portuguese man-o-war, which is sometimes common on our shores after sustained southerly winds during summer. A few of our locally common species that cause pain but of a generally less-severe nature include the moon jelly, sea nettle, and cannonball jellyfish. We even have some species of hydroids that look very much like a bushy brown or red algae. They are usually attached to the bottom substrate but when pieces break off and drift into the surf they can provide a painful encounter.
If you are stung there are a couple of things you can do to help and a couple of things you should not do. First, move away from the location by getting out of the water so you don’t encounter more tentacles. Carefully remove any visible tentacle pieces but not with your fingers. You should also change out of swimwear that may have trapped pieces of tentacles or tiny larval jellyfish against the skin. Do not rinse the area with fresh water as this causes the remaining stinging cells to fire their venomous harpoons. If symptoms go beyond a painful sting to having difficulty breathing or chest pain you should immediately call the Poison Information Center Network at 1-800-222-1222 or call 911.
Another thing to watch for in areas where public beaches display the beach warning flag system is a purple flag. This flag color at the beach indicates dangerous marine life and quite often it is flown when jellyfish numbers are at high levels. All of this is being written, not to scare you away from our beaches, but to help you enjoy our beautiful coastline with a little better understanding of what is out there and what to do if you happen to have a brush with a jellyfish. The vast majority of encounters are a minor irritation in an otherwise pleasant experience.

Invasive species are non-native or exotic species that do not naturally occur in an area, cause economic or environmental harm, or negatively impact human health. These invasive species have become the number one threat to biodiversity on protected lands. However, invasive species do not know boundaries, and as a result, public, private lands, natural and man-made water bodies, and associated watersheds are affected. National Invasive Species Awareness Week (NISAW) is February 21-27, 2016.
It is estimated that Florida Agriculture loses $179 million annually from invasive pests (http://www.defenders.org/sites/default/files/publications/florida.pdf). Generally, eradication of an invasive species is difficult and expensive. Most of the mitigation efforts focus on control rather than eradication.
EDDMaps (Early Detection and Distribution Mapping System), a web-based mapping system for reporting invasive species, currently has 667 different invasive plants reported in Florida. Many invasive insects, animals and diseases have also landed in Florida. Some famous invasive species in Florida include cogongrass, wild hogs, red imported fire ants, Chinese tallow, and lionfish.
For National Invasive Species Awareness Week, the University of Florida IFAS Northwest Extension District will highlight two invasive species each day. There are a couple of ways to receive this information each day of NISAW:
You can help us control invasive species in several ways. First, always be cautious when bringing plants or plant materials into the state. Plants or even dead plant material can harbor weeds, insects and diseases that can become invasive in our state. Second, when you see something suspicious, contact your local extension agent for help identifying the weed, insect or disease. Third, you can volunteer your time and effort. Invasive species control is difficult and requires a cooperative effort for funding and manpower. The state has several Cooperative Invasive Species Management Areas (CISMA) in which public and private organizations work together to control invasive species in their area. These CISMAs hold work days in which volunteers can help remove invasive species from the environment.
For more information about NISAW or invasive species, contact your local county extension agent.

As summer browse dwindles the habitat improvement associate with wildlife food plots becomes even more evident.

Improving habitat can benefit the quantity and quality of wildlife on a piece of property. One common method for improving habitat is the establishment of food plots. Food plots are simply areas that are managed for the production of forages that help meet the nutritional requirements of the desired wildlife species.
The implementation of food plots has gained popularity largely through its association with hunting, specifically white-tailed deer hunting. Food plot establishment and hunting success can be directly related; attracting game to a specific area via the establishment of a highly desirable plant species. That said, rarely are food plots which are planned and utilized only as attractants very successful. Truly successful food plots are developed with yearlong habitat improvement in mind; improved hunting on the property is a by-product of the improvement in habitat.
Successful implementation of wildlife food plots takes planning and consideration. Many factors must be considered;
- Site selection: Factors like size, shape, soil characteristics, and location can greatly affect the potential success of a food plot.
- Nutritional demands of wildlife: Throughout the course of the year the nutritional demands of wildlife change. Wildlife, especially deer, will show preferences for different plants at different times of the year based largely on the nutritive value of the plant. Successful food plots seasonally match the nutrition offered to the nutrition need by the wildlife.
- Plant selection: Selecting the best species and varieties to plant in a food plot is a decision that tends to get a lot of attention, and rightfully so. Plantings should be selected based on how well they are adapted to the site, propensity of wildlife to utilize them, and how well they fit into the yearlong rotation. It is always advisable to plant a blend of multiple species, planting windows and persistence of the plants must be considered when formulating these blends.
- Agronomic practices: If all other factors are considered and appropriately addressed the success of a food plot is still dependent on the ability of the land manager to effectively plant and manage the crop(s). Soil fertility, weed control, planting depth, seeding rate, etc. all need to be correctly addressed to have a successful food plot.
Planning and hard work are prerequisites for successful food plots but when everything comes together seeing the benefits they provide can be a truly rewarding experience. If you are interested in learning more about successfully improving wildlife habitat through the implementation of food plots please consider attending Wildlife Food Plot Fundamentals. This workshop will be at the Washington County Agricultural Center on Thursday October 8th beginning at 6:30pm. Please see the flyer for more details, for questions or to register contact Mark Mauldin with UF/IFAS Extension, Washington County (850-638-6180, mdm83@ufl.edu).

I am not going to lie… I skipped August… It was hot…
September however was nice. The day I made the hike the skies were clear and the temperature was 75°F! wonderfully… truly wonderful.
If you are like me you probably begin your day around the same time – and have probably noticed that it is darker when you get up. September 22 is the fall equinox and the length of our day will be exactly 12 hours of daylight and 12 hours of darkness. We then enter the “dark side” of the calendar year – the days will become shorter… and already have. As we move into autumn on our beaches we will notice some changes. One, fewer visitors, but we will also notice changes in wildlife.

Many counties in the panhandle have lighting and barrier ordinances to protect wildlife and workers.

As you can see in the photograph the scarp of the shoreline is becoming more pronounced. As the sun begins to spend more time below the horizon the winds shift, the waves change, sand is moved more offshore and the shape of our beach changes as well. You may have noticed the purple safety flags have been flying a lot recently. These mean “dangerous sea life” and we have been seeing a lot of jellyfish as the summer comes to a close. Today I noticed a lot of ghost crab holes. These guys are always around but their presence seems more noticeable this time of year – possibly due to more available food. Over the last six months I have been working with CleanPeace and the Escambia County Division of Marine Resources monitoring marine debris. Our objective is to determine what the major local debris issues are and develop an education program to try and reduce these problems. Cigarette butts have been consistently the #1 item since January. Many of you probably remember the “Keep Your Butt off the Beach” campaign a few years back… apparently did not worked well. We will have to educate locals and visitors to please take their cigarette butts with them. For those in Escambia County you will now notice the new Leave No Trace signs. The Escambia County Board of County Commissioners passed a new ordinance this past month that requires all residents and visitors to remove items from the beach overnight. Not only have these negatively impacted nesting sea turtles they have become a hazard for evening work crews and the general public. Most panhandle counties have some form of “Leave No Trace”. Please help educate everyone about their ordinances.

Fall is the time of the monarch movement. Typically they begin to show in numbers after the equinox but we did see a few on the island this week. Be ready, next month should be full of them. The sandspurs were beginning to develop their spiny seed pods. I would caution all to check their shoes and clothing before leaving the beach this time of year to avoid carrying these seed pods home and distributing them in your yard… uncool.

We did see evidence of snake movement this week. There are several species, including the Eastern Diamondback Rattler, which will breed in the fall as well as the spring. I expect to see more activity as the days grow shorter. The dragonflies were very active this month. Actually my wife witnessed two of them consistently pestering a monarch butterfly until the butterfly moved away. I have seen armadillo activity every month of the year so far, this month was no different. The islands seem full of them. This lone Chinese Tallow has formed a small dune where other plants have established and many creatures have taken up residence. At this time there are no other Tallow in the area, and this one will need to be removed before the spread begins. But it is an interesting paradox in that there was an armadillo burrow found here and the sea oats have utilized this dune as well. Invasive species are a problem throughout the state and many have caused with economic or environmental problems – or both! Though this tree has participated in establishing a much needed dune on our hurricane beaten island – native plants do the same and should be favored over non-native. We will have to remove this tree.
An unknown track; possibly of a turtle hatching.

This tick was a hitchhiker on our trip through the dunes.

This track was found in the tertiary dune system and could be an adult turtle.

This small track has the appearance of a “turtle crawl”. It certainly is not a sea turtle, in the middle of the dune field for one thing, but there are several freshwater ponds on our islands that harbor a variety of “riverine turtles”. I know that Cooters, Sliders, and Snappers live on Santa Rosa Island. Terrapins are found in salt marshes. Not sure if this is a turtle but all should be aware that now is hatching time. Many turtle nests began hatching about a month ago and young turtles can be found in a lot of locations. The track in this picture is from a very small animal.
Ticks… yep ticks… It is hard to do a lot of fun outdoor activity in the southeast without encountering these guys. They like to sit on top of tall grass and wait for a mammal to come rummaging through. After each hike we always do a “tick check”. I typically wash my hiking clothes AS SOON AS I GET HOME – in case they are harboring within… I would recommend you do the same. We have been following the “mystery track” since January. This “bed” we have seen each month is in the same location. I thought I had solved the mystery in July when I found armadillo tracks all around it but this month suggest this is not an armadillo. We are not sure what it is – we are leaning towards alligator or otter (both of which can be found – and have been found – on our islands). We will continue to monitor this and hopefully find the sculptor.

The seagrass in the sound looked very thick and healthy this month. I have seen horseshoe crab here over the summer and Sea Grant conducted a scallop survey in Santa Rosa Sound and Big Lagoon within Santa Rosa and Escambia counties in August. We found no live scallop but plenty of dead ones – and some of that shell material was relatively “new”. Since scallops only live a year or two this is a good sign. There has been plenty of anecdotal evidence of live ones in the area. REMEMBER THAT IT IS ILLEGAL TO HARVEST SCALLOP WEST OF PORT ST. JOE AND ONLY FROM JUNE 27 TO SEPTEMBER 24 (Learn More). We will continue to conduct these surveys each summer to determine if our area would be a good candidate for a scallop restoration project.
As the days shorten and cool – I am expecting more wildlife activity to begin. Until next month.
