The Snake Watch Project is one that is helping residents in the Pensacola Bay area better understand which species of snakes are most encountered, where they are encountered, and what time of year. The project began in 2022 and over the last two years between 50-60% of the 40 species/subspecies of snakes known in the Pensacola Bay area have been encountered. The majority of these encounters have been in the spring, with garter snakes, black racers, banded water snakes and cottonmouths being the most common.

The 1st quarter reports cover the winter months, and you would expect fewer encounters – but encounters do happen. In 2022 there were only 6 encounters during the winter months. There was one mid-sized snake (between 12-24” maximum length), 2 large snakes (greater than 3’ maximum length), 1 water snake and 2 cottonmouths for a total of five species. In 2023 there was a significant increase in 1st quarter reports. There were 57 encounters (26% of the total for the year) and 13 species logged.
Two species of small snakes (less than 12” maximum length) were encountered three times.
Three species of mid-sized snakes were encountered nine times, this included an encounter with the eastern hognose snake.
Six species of large snakes were encountered 17 times. These include the rarely seen eastern kingsnake and Florida pine snake.
Three species of water snakes were encountered, including the green water snake.
The cottonmouth was encountered 10 times during the 1st quarter of 2023.
This increase in sightings may be more a result of more people interested in the project than a true increase in snake activity, but it does provide us with information on snake activity during the winter months. Eastern garter snakes, eastern ribbon snakes, banded water snakes, and cottonmouths were the most frequently encountered.

Snake encounters during the 1st Quarter of 2024 are down. This year 27 encounters occurred logging eight species. The cottonmouth continues to be the most encountered snake in our area and the only one who was encountered in double digits (n=11). Other species encountered included the eastern garter snake, eastern ribbon snake, gray rat snake, corn snake, southern black racer (encountered every month), eastern coachwhip, banded water snake (encountered every month), and the cottonmouth (also encountered each month this quarter).
We will continue to log encounters during the spring. If you see a snake, please let Rick O’Connor know at roc1@ufl.edu.
Cogongrass (Imperata cylindrica) is one of the most noxious weeds in the U.S. and has been a problem in the agricultural and timberland for decades. In more recent years it has been found on our barrier islands. Stands of cogongrass on the beaches are not as massive and dense as they are in the upland regions of our district, but now is the time to try and manage it before it does. And NOW is the time to identify whether you have it on your property or not – it is in seed.

Cogongrass produces blades that resemble St. Augustine but are taller and wider. The blades can reach a height of three feet and the color is more of a yellow green (lime green) than the deep green of St. Augustine. If you can touch the blade, you will notice that the midline of the parallel leaf veins is off center slightly and the edges of the blades are serrated – feeling like a saw blade when you run fingers from top to bottom. They usually form dense stands – with a clumping appearance and, as mentioned, it is currently in seed, and this is very helpful with identification.

The seeds are white, fluffy and elongated extending above the plant so the wind can catch them – similar to dandelions. These can easily be seen from the highway or riding your bike through the neighborhoods. As mentioned above, if you see seeds like this you can confirm the identification by examining the leaf blades. You can also send photos to your county extension office.

If the identification is confirmed the next step is to report the location on EDDMapS – https://www.eddmaps.org. You can also do this with the free app IveGotOne (which can be found on the EDDMapS website or any app store). HOWEVER, you cannot report private property without their permission.
The next step would be management. It is not recommended to mow or disturb the plant while in seed. Herbicide treatment is most effective in the fall. Many will mow the plant, allow the grass to resprout no more than 12 inches, and treat this with an herbicide. It is recommended that you contact your county extension office for recommendations as to which herbicide to use and how.
The negative impacts of this noxious grass have been an issue in the upland communities for decades. There have been few major issues with it in the coastal zone, but early detection rapid response is the most effective management plan to keep negative impacts from occurring. We encourage coastal communities to survey for cogongrass while it is in seed and develop a management plan for the fall.
What is 54 years old and growing better with age? Earth Day! Every year on April 22, we mark the anniversary of the birth of the modern environmental movement.
Prior to 1970, America and Americans lived with a host of environmental threats and concerns from automobile emissions due to leaded gas, industrial waste, and unchecked air pollution.
While a public awakening began to grow after 1962 when Rachel Carson published Silent Spring, it wasn’t until 1969 when a massive oil spill in Santa Barbara, California inspired long-term change.
Senator Gaylord Nelson, an environmentally conscious junior senator from Wisconsin, spearheaded the movement when he saw the potential to engage students to raise public consciousness about air and water pollution. He partnered with Denis Hayes, a young activist, to organize campus teach-ins and to scale the idea to a broader public.
April 22 was chosen as the date, a weekday falling between Spring Break and Final Exams, to maximize the greatest student participation. They branded the event Earth Day and promoted the event nationally. The first Earth Day inspired 20 million Americans, 10% of the population at the time, to participate and demonstrate against the harmful impacts of unsustainable industrial development.
This first Earth Day united groups that had previously been fighting individually against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness and the extinction of wildlife. It also let to the creation of the United States Environmental Protection Agency and many of the environmental protection laws we have today, including the Clean Water Act.
Today, Earth Day celebrations continue, both as protests and celebrations. Here in the Florida Panhandle, one way we celebrate Earth Day is by supporting beach cleanups. It is one avenue to give back to our communities and help take care of the environment that we love.
Why not take the time to celebrate 54 years of progress and tradition? Find a way to celebrate Earth Day this coming April 22, 2024.
In 2005 I was leading a field trip with high school students in a salt marsh on Santa Rosa Island near Pensacola Beach. As we explored a brackish water creek, we came across a three-foot red mangrove tree, prop roots and all. To say we were surprised and excited would be an understatement.
Most know that mangroves are trees that can tolerate seawater and grow along estuarine shorelines across the tropics, including south Florida. They can form dense forests that support all sorts of aquatic and terrestrial wildlife. They need calm protected waters to establish themselves but once established are excellent at protecting shoreline communities during hurricanes. However, they cannot tolerate cold weather, only surviving freezing temperatures for one or two nights.

Growing up in Pensacola we would often find red mangrove propagules (seedlings) washed ashore arriving from the tropical parts of the Gulf. They were generally on the Gulf side of Santa Rosa Island and Perdido Key but never germinated. If they were carried into the estuary, and found a protected lagoon to begin germination, they would not survive our winters. This is what made finding an established three-foot mangrove in a lagoon off Santa Rosa Sound in 2005 so surprising.

Historically mangroves were not found north of Tampa Bay. However, in recent decades they have become established as far north as Cedar Key. Trying to determine whether the mangrove we found was the northern most in Florida I found that they were also expanding along the east coast of Florida as far north as St. Augustine, and there were records in the Jacksonville area. Many attribute this to climate change. Our winters are milder than they were when I was a kid, and this may be leading to what many are calling the “tropicalization of northern Gulf of Mexico”. Not only mangroves, but other historically south Florida species, such as snook and bonefish, have been reported along the panhandle.
In 2017 I was leading another high school group on a field trip in a salt marsh in Big Lagoon State Park. We found a germinated seedling of a red mangrove doing very well. We explored more and found seven others in the nearby area. How many more were growing in the Pensacola Bay area?

We partnered with a research team from Dauphin Island Sea Lab who was looking into this as well. The team included extension agents and specialists from Florida and Mississippi-Alabama Sea Grant, as well as biologists from the National Estuarine Research Reserves in Mississippi, Alabama, and Florida panhandle. Each county/region selected 10 transect sites that had the highest probability of mangroves to monitor each year. Mangroves appear to be established on some of the Mississippi barrier islands, as well as in St. Joe Bay. Individuals have been reported from Bay County. A ninth mangrove was found in Escambia County but a hard freeze in 2018 killed them all. Since then, one young multi-year red mangrove was found on NAS Pensacola. It died in the hard freeze of 2023. Despite the hard freezes, those established in St. Joe Bay seem to be holding on. I decided to make a visit and see.

Wading out from the buffer preserve with Gulf County Sea Grant Agent Ray Bodrey, we found relatively large patches of mangroves, and seeds suggesting active expansion was ongoing. But I noticed the species we were seeing were black mangroves. I mentioned to Ray that what we had seen in Pensacola were red mangroves. He said that the red mangroves have a hard time here as well. Black mangroves are more tolerant of cold weather, and it is they who are establishing these large patches. There are reports of large patches of mangroves on the Mississippi barrier islands – and they are the black mangroves as well. I know that black mangroves have been established in the Chandeleur Islands in Louisiana for decades. I am convinced that if black mangroves seeds were to reach protected lagoons in Pensacola Bay, they would probably do well here as well.
I continue to conduct our transects each year in the Pensacola Bay area. I have a couple of trained volunteers helping me but could always use more. If you think you have seen a mangrove growing in the Florida panhandle, we would love to know and document their location. We know they are established in Gulf County, so our focus is now Escambia to Bay counties. If you think you have seen one, contact me at roc1@ul.edu or your county Sea Grant Agent.
