Most plant and wildlife communities in Florida are adapted to periodic fires. For thousands of years, fires were ignited naturally, and frequently, by lightning. In fact, Florida has the greatest number of lightning strikes of any state in the country. About 1,000 lightning-set fires are documented in Florida each year.
Today, due to the many people living in Florida, the vast majority of fires naturally ignited by lightning are quickly suppressed by trained personnel. This is done to reduce the loss of human life and property. Although helpful to human safety in the short term, suppression of fire from natural areas for long periods of time can be problematic for all the native plant communities and wildlife that are adapted to periodic fire, and ultimately dangerous for humans as well. The longer our natural areas go unburned, the greater the accumulation of vegetative material that could serve as fuel for fire, and the greater the possibility of uncontrollable wildfires devastating natural areas, homes, and buildings when lightning strikes.
PRESCRIBED FIRES are an important tool: they are a safe alternative to wildfires. Prescribed fires are intentionally set under favorable weather conditions with the goal of stimulating the ecological benefits produced by natural wildfires. By selecting safe conditions for these burns and by preparing for them in advance by creating barriers to halt the spread of fire past desired borders, trained personnel have much more control over the results of these fires. The reason we often see and smell smoke in the spring is because this is the most popular time of year to use prescribed burning as a forest management tool.
Below are some of the benefits fire provides to the health of the many plants and wildlife that naturally occur in our state.
- Fire maintains required habitat conditions for many of Florida’s plant and wildlife species.
- Fire promotes fruit production of many woody plant species.
- Fire promotes flowering of herbaceous (non-woody) plant species.
- Fire promotes diverse herbaceous plants that serve as food for insects and wildlife.
- Fire scarifies seeds, breaking down their hard seed coats and promoting germination.
- Fire prepares sites for seeding or planting of species that require bare mineral soil.
- Fire creates growing conditions required by some cone-bearing trees. It reduces leaf litter on the soil surface, increases nutrient reserves, and canopy openings so that sunlight can reach the forest floor.
- Fire releases nutrients bound up in dead organic matter, ultimately increasing palatability, digestibility, and nutritional value of growing plants for wildlife.
- Fire can improve the quality of forage for grazing livestock.
- Fire changes the density of trees in the forest, creating space for some wildlife species.
- Fire removes hardwood thickets and vines in the understory of pine forests, making these areas more suitable for some wildlife species.
- Fire controls insect pests and diseases that afflict pine trees.
- Fire increases the rate of nutrient cycling of some elements and elevates soil pH.
- Fire creates a diverse habitat conditions when fires are patchy, leaving pockets of unburned areas.
- Fire reduces the risk of severe, high intensity wildfires that could cause harm to native plants and wildlife by preventing the accumulation of highly-flammable, dead vegetation.
The last week in January has been designated as Prescribed Fire Awareness Week in Florida. Early February has been designated as Prescribed Fire Awareness Week in Georgia. March is Prescribed Fire Awareness Month in South Carolina. Why are so many southern states making a big deal about prescribed fire? It is because we have recognized the importance of safe fires for both the health of our native plants and wildlife as well as the safety of our human residents and visitors. If you see or smell smoke in a nearby natural area, it might well be coming from a prescribed fire intended to benefit our natural plants and wildlife as well as our safety.

Along the Chipola River in Florida’s Panhandle, farmers are doing their part to protect critical Shoal Bass habitat by implementing agricultural Best Management Practices (BMPs) that reduce sediment and nutrient runoff, and help conserve water.
Florida’s Shoal Bass
Lurking in the clear spring-fed Chipola River among limerock shoals and eel grass, is a predatory powerhouse, perfectly camouflaged in green and olive with tiger stripes along its body. The Shoal Bass (a species of Black Bass) tips the scale at just under 6 lbs. But what it lacks in size, it makes up for in power. Unlike any other bass, and found nowhere else in Florida, anglers travel long distances for a chance to pursue it. Floating along the swift current, rocks, and shoals will make you feel like you’ve been transported hundreds of miles away to the Georgia Piedmont, and it’s only the Live Oaks and palms overhanging the river that remind you that you’re still in Florida, and in a truly unique place.
Native to only one river basin in the world, the Apalachicola-Chattahoochee-Flint (ACF) River Basin, habitat loss is putting this species at risk. The Shoal Bass is a fluvial specialist, which means it can only survive in flowing water. Dams and reservoirs have eliminated habitat and isolated populations. Sediment runoff into waterways smothers habitat and prevents the species from reproducing.
In the Chipola River, the population is stable but its range is limited. Some of the most robust Shoal Bass numbers are found in a 6.5-mile section between the Peacock Bridge and Johnny Boy boat ramp. The Florida Fish and Wildlife Conservation Commission has turned this section into a Shoal Bass catch and release only zone to protect the population. However, impacts from agricultural production and ranching, like erosion and nutrient runoff can degrade the habitat needed for the Shoal Bass to spawn.

Shoal Bass habitat conservation and BMPs
In 2010, the Southeast Aquatic Resources Partnership (SARP), the National Fish and Wildlife Foundation and a group of scientists (the Black Bass Committee) developed the Native Black Bass Initiative. The goal of the initiative is to increase research and the protection of three Black Bass species native to the Southeast, including the Shoal Bass. It also defined the Shoal Bass as a keystone species, meaning protection of this apex predators’ habitat benefits a host of other threatened and endangered species.
Along the Chipola River, farmers are teaming up with SARP and other partners to protect Shoal Bass habitat and improve farming operations through BMP implementation. A major goal is to protect the river’s riparian zones (the areas along the borders). When healthy, these areas act like sponges by absorbing nutrients and sediment runoff. Livestock often degrade riparian zones by trampling vegetation and destroying the streambank when they go down to a river to drink. Farmers are installing alternative water supplies, like water wells and troughs in fields, and fencing out cattle from waterways to protect these buffer areas and improve water quality. Row crop farmers are helping conserve water in the river basin by using advanced irrigation technologies like soil moisture sensors to better inform irrigation scheduling and variable rate irrigation to increase irrigation efficiency. Cost-share funding from SARP, the USDA-NRCS and FDACS provide resources and technical expertise for farmers to implement these BMPs.

By working together in the Chipola River Basin, farmers, fisheries scientists and resource managers are helping ensure that critical habitat for Shoal Bass remains healthy. Not only is this important for the species and resource, but it will ensure that future generations can continue to enjoy this unique river and seeing one of these fish. So the next time you catch a Shoal Bass, thank a farmer.

It has been one crazy year in the world of natural resources in the Florida panhandle. I guess the top stories would be the red tide and, of course, Hurricane Michael. Both had an impact environmentally and economically in the area.

We did not see the red tide in the panhandle until late summer. The folks in southwest Florida had been dealing with it since late winter. Down there, large fish kills were driving away tourists and halting the charter fishing industry. People began canceling their hotel reservations and moving to the east coast of the state, which eventually had red tide as well. One report showed a 6% decrease in tourism for that region, may have been more. It was certainly devastating and there is now a bill in U.S. congress to fund red tide research and monitoring. They are wanting to be able to predict them better, and possibly reduce their impacts.
Here in the panhandle the economic impact was not as large. One, it came later in the year – beyond our busy season, and two Hurricane Michael occurred, which had a far greater environmental and economic impact. That said, FWC will continue to monitor for red tide and hope it will not be a story this year.
Hurricane Michael was huge as far as environmental and economic impacts for the natural resources in the region. Charter captains either had no boats, no crew, no marina, or no customers – in some cases, all of the above, and business suffered. For some fishing interest, we were past the closed season but for divers, and other fishing interest, the loss was definitely felt.
It was no different for the commercial fishing industry. In addition to boat, crew, and marina issues, oyster cages in the Apalach area were tossed up on beaches or lost all together. Product leaving the area, if you could harvest, was okay – but for those looking for local seafood in the area you had the problem with closed restaurants and seafood markets.
Here is an example of the damage to local marinas and vessels that service our local fisheries. Unseen is the economic damage to fishing crews and supporting shore base businesses such as seafood processors, bait and tackle shops, and tourism related businesses. (Photo by Allen Golden).
Above the coast, there were problems with downed trees – making commuting impossible and, in some cases, costing landowners a lot of money. Pecan orchards were hit hard, as were some of the timber interest. There were reports of livestock loose due to crushed fences from downed trees. Those they could hold on to did not have barns to put them in and feed was in low supply.
Then you had to be concerned about the quality of the water. Excessive rain equals high levels of bacteria, even in private wells there could be contamination. With time all things tend to return. Some local residents may be restoring their natural resources for some time, others may be back in business now. It was a tough hit for the area this year.
Other natural resource notes for 2018 include bear sightings. This continues to be an issue in the panhandle, particularly in Santa Rosa County. There have been manatees visiting the Big Lagoon area of Pensacola Bay during the last two years – something they do not often see. Also, in the Pensacola area has been an increase in calls about venomous snakes. Hard to say if there are more snakes than there once were, or whether they are becoming more visible, but it was a story that we will continue to watch this year.
At the 2018 FWC lionfish summit it was mentioned that lionfish are harder to find in waters shallower than 120’, this is good news. The story is not over yet but seems the harvesting we have been doing has helped. We will be having a regional lionfish workshop February 19 in Ft. Walton Beach for those interested in learning more about this issue. That will be followed the next day with a workshop on local artificial reefs. Registration information will be posted soon.

As we now look at 2019 there will certainly be new natural resource stories. There are a couple of bills recently introduced at the state level dealing with septic tank inspections, lawn fertilizer, maintaining our springs, and sewage spills designed to help improve water quality – we will see what happens with those. There is much discussion on coastal resiliency and how to reduce the impacts of future hurricanes and we will continue to monitor changes in our area such as invasive species and mangrove distribution.
If you have a topic you would like to see an article about, please let us know. We hope you had a great holiday season and we look forward to a good new year.

The week prior to Halloween is officially designated as National Bat Week. In honor of this event, it’s worth considering some of the benefits bats provide to us.
Did you know there is a species of bat that lives nowhere in the world but within our state? It’s called the Florida Bonneted Bat, and occurs in only about 12-15 counties in south and central FL. These bats are so mysterious that we’re currently not even sure exactly where they occur. They are so rare that they’re listed as a federally endangered species.

These bats were named for their forward-leaning ears, which they can tilt forward to cover their eyes. With a wingspan of 20 inches, they are the largest bats east of the Mississippi River: only two U.S. species are larger than they are, and these both occur out west.
We have been investigating the diet of Florida Bonneted Bats. To do this, we captured bats in specialized nets, and then collected their scat (called guano). Next, we processed the scat in a laboratory using DNA metabarcoding to determine which insect species the bats had recently consumed.
We found that the bats eat several economically important insects, including the following:
- fall armyworm (Spodoptera frugiperda)
- lesser cornstalk borer (Elasmopalpus lignosellus)
- tobacco hornworm (Manduca sexta)
- black cutworm (Agrotis ipsilon)
These insects are pests of corn, cotton, peanut, soybean, sorghum, tobacco, tomato, potato, and many other crops.
Furthermore, the bats did not eat these insect pests infrequently. In fact, 86% of the samples we examined contained at least one pest species. On average, each sample contained three pest species! This tells us that Florida Bonneted Bats should be considered IPM (Integrated Pest Management) agents.
Currently, a new student has begun investigating the diets of bats more commonly found in northern Florida, southern Georgia, and southern Alabama. By the time Bat Week 2019 rolls around we’ll have details on which insect pests these bats could eat on your property.
If you’re interested in helping bats or incorporating them into your Integrated Pest Management efforts, consider creating roosts for them (places where the bats can sleep during the day). Bats roost not only in caves, but also in cavities in trees, in dead palm fronds, and in bat houses.

The Wacissa River offers paddlers the opportunity to see north Florida unfiltered.
Being off the beaten path has many advantages. In the case of a spring-fed river, it translates to less pressure from human use and a great opportunity for those who do visit to experience the “real Florida”.
The Wacissa River, located in the southern half of Jefferson County, Florida, is near the crossroads identified as the town of Wacissa. There is a blinking light, a post office, and two small convenience stores where beer, ice and snacks can be purchased.
Access to the river is about two miles south of the blinking light on Florida 59, just after the state road veers to the southwest. The blacktop spur quickly become a dirt parking lot after passing several canoe and kayak rental businesses.
A county maintained boat landing with pick-nic tables, a manmade beach, and a tiny diving platform with a rope swing are the only signs of civilization. The cold, clear water extends to a tree line several hundred yards south of the landing with the river moving to the southeast.
The river emerges crystal clear from multiple limestone springs along the first mile and a half of the 12 mile waterway. The adjacent land is flat and subject to being swampy, especially in wet years like 2018.
The river terrain stands in contrast to the Cody Scarp just a few miles to the north. This geologic feature is the remnants of an ancient marine terrace and is hilly, rising 100 feet above the river in some spots.
Cypress, oak, pine, and other trees cover the bottomlands adjacent to the river. The river quickly enters the Aucilla Wildlife Management Area which results in a wide variety of animals, birds, amphibians and reptiles.
The wildlife viewing varies by season. Many migratory birds use the river’s shelter and resources on their annual trips.
Canoeing and kayaking are popular in the gentle current. Powerboats and fan boats can use the area also, but must be on constant alert for shallow spots and hidden snags.
For the adventurous paddler who wants to follow the river’s course, there is a debarkation point at Goose Pasture Campgrounds and another near St. Marks after the Wacissa merges with the Aucilla.
Be prepared when taking this journey. This is the real Florida, no fast food restaurants or convenience stores. Only clear water, big trees and the calls of birds will be found here.

Bumble bees and other pollinators often visit the vast fields of cotton flowers in north Florida’s agricultural lands. Although cotton is mainly self-pollinating, pollination by bees can increase seed-set per cotton boll. Note the pollen grains stuck on each bee. Photo by Judy Biss
Beekeeping is thriving in Panhandle Florida and the importance of honeybee health and pollination is frequently in the news. As much as 1/3 of our food supply depends on the pollinating activities of honeybees, and because of this fact, pollinator protection was formally recognized at the federal level in 2014 when the President of the United States signed the memorandum called: Creating a Federal Strategy to Promote the Health of Honey Bees and Other Pollinators.
The goals of this policy are to increase and improve pollinator habitat for not only managed European honeybee colonies, but also native bees, birds, bats, and butterflies – all of which are vital to our nation’s economy, food production, and environmental health.
So, of the variety of pollinating insects and animals, what are some of Florida’s native pollinating bees? What do they look like and what are their characteristics? Let’s take a look at a few. Follow the links provided for additional, fascinating details. I will start with one of my favorites, because it happens to pollinate one of my favorite fruits. Blueberries!

While managed honeybees can pollinate blueberries, the Southeastern blueberry bee, as well as bumblebees, are much more efficient pollinators of this crop. These bees “sonicate” the flowers to release more pollen. Sonication, or buzz pollination is caused by the bee’s high-speed wing beats vibrating the flower causing pollen to fall onto the bee. As we will see with many of our native bees, the Southeastern Blueberry bee is a solitary bee meaning it does not live in colonies like the European honeybee. The Southeastern Blueberry bee digs burrows in the ground where they lay eggs that hatch the following year to start the cycle over again.

Blue orchard bees are native to the United States and Canada, and are important pollinators of a variety of fruits including blueberries. They are solitary bees most active in the early spring and summer. They are part of a group of bees called mason bees that use holes or tube-like structures to nest in. Some garden supply stores now carry native bee nesting cavities such as stacks of bamboo or blocks of wood with holes of varying sizes that you can use to attract these native pollinators to your backyard.
Many native pollinating bees, such as the mason bees, are solitary in nature and can be attracted to your backyard by providing nesting habitat. Bee nesting “houses,” such as this block of wood with pre-drilled holes, are available for sale more frequently now in garden supply stores. Note the cavities that were used indicated by the mud-like plugs. Photo by Judy Biss

A few years ago, our office received a call about a number of bees flying around a large pile of fill dirt in one of our local parks. It turned out to be the nesting site of these fascinating bees. These bees are solitary, yet gregarious. Solitary in that the female builds her own burrow in the ground in which to lay her egg; gregarious in that they tend to congregate together to build their individual burrows. They are pollinators of a number of plants, including fruits and vegetables.

Bumble bees are among the most recognizable of insects. They are large, colorful, and a wonder to watch. They are also important pollinators of both native plants and agricultural crops. Bumble bees are so effective at pollinating important food crops, they are raised commercially and sold to pollinate produce such as tomatoes, peppers, cranberries, and strawberries. Blueberries and other commercially important food crops benefit from the bumblebees’ ability to “sonicate,” or “buzz pollinate,” as described above. They are social bees forming small colonies (50 – 500 individuals) in the ground or empty cavities, which only last one season.
Leafcutting bees are a group of important native pollinators found throughout the world, including North America. In Florida, there are approximately 63 different species of leafcutting bees, one of which is Osmia lignaria listed above (Blue Orchard Bee). As the name implies, these solitary bees cut neat circles from broadleaf deciduous plants which they use to build their long tubular nests. While their leaf cutting capabilities can sometimes decrease the esthetics of some common landscape plants, their actions will not harm the plants. They are pollinators of wildflowers and many of our fruits and vegetables.

Sweat bees are important pollinators for many wildflowers and fruits and vegetables, including peaches, plums, apples, pears, alfalfa and sunflower. This family of bees (Halictidae) contains one of the largest genera of bees in the world, displaying a wide range of social, nesting, physical, and foraging characteristics. In Florida, there are 44 species of sweat bees.
So, the next time you are walking in the garden, or hiking in Florida’s beautiful woodlands and pastures, slow down to catch of glimpse of these busy and critically important insect pollinators. I for one am quite grateful for those bees that help produce an abundance of food… especially blueberries!
