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. Photo: Rick O’Connor
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. Photo: Molly O’Connor
This tick was a hitchhiker on our trip through the dunes. Photo: Molly O’Connor
This track was found in the tertiary dune system and could be an adult turtle. Photo: Rick O’Connor
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.
This month there were many more plants flowering… it is true that April showers do bring May flowers. May not only brings more flowers but more tourists. Everyone is out enjoying the weather, including some wildlife. I was happy to include Florida Master Naturalist Paul Bennett on this hike and he was very helpful identifying plants. Thanks Paul!
Tent set up on Pensacola beach to protect from the sun. Photo: Rick O’Connor
Sign altering and educating folks that this is a sea turtle nest. Photo: Rick O’Connor
It is sea turtle nesting season all along the Florida Panhandle. The season begins in May and ends in October. This time of the season the females are heading up the beach looking for good nesting locations near dunes. There are five species of marine turtles that inhabit the northern Gulf and there are records of each species nesting here. They emerge at night and move towards the dunes where they excavate a deep cavity to lay about 100 eggs. The nest is covered and she returns to the water. The incubation period is between 60-70 days and the temperature of the nest determines the sex of the hatchling; the warmer eggs becoming females. It is illegal to disturb a sea turtle nest.
This tent was occupied when I was there but all too often they are left overnight so folks can return the same spot the following day. Tents and chairs are barriers for both nesting females and emerging hatchlings. If at all possible, remove these for the evening. In some counties it is required. Another problem is artificial lighting. Adult turtles are distracted, and many times abort the nesting activity due to bright lights. Most panhandle counties have a lighting ordinance that requires homes to use turtle friendly lighting. To learn more about the turtle friendly lighting program and local ordinances contact your county Sea Grant Agent at the local Extension office or visit http://myfwc.com/wildlifehabitats/managed/sea-turtles/lighting/.
This county sign marks a public snorkel reef and also educates everyone about lionfish. Photo: Rick O’Connor
Mangrove seed washed ashore. Photo: Rick O’Connor
Summer means swimming and in many local counties there are interesting snorkel reefs nearby. We asked that everyone keep an eye out for the invasive lionfish as they enjoy their day. If one is spotted be aware they do have venomous, though not deadly, spines and please contact your local Sea Grant Agent at the county Extension office to let them know. If you are in Escambia County you can log your sighting at www.lionfishmap.organd FWC has a lionfish app for reporting; http://myfwc.com/news/news-releases/2014/may/28/lionfish-app/
The seed is of a red mangrove tree. These are common coastal plants in south Florida and elsewhere in the tropics. The red mangroves drops their seeds (propagules) into the water to drift in the currents to new locations. They frequently wash upon our shores and sometimes take root, but they do not last during our colder winters.

The flower to the left is the Whitlow-Wort, or as some locals call it… “square flower”. The track is of a snake but could not find it so I am not sure which species. The weather warms quickly here along the Gulf coast. A few months ago we may have been able to find this animal but with the increasing heat they were in a cool place somewhere. Snake encounters this time of year are typically at dawn and dusk.

The milkweed bloomed a few months ago but here in May we find both the seed pods and, in the photo to the right, the “dandelion-like” seeds being released. This is one of the plants used by the migrating monarchs, which we should see later in the year.
Marsh Pink, a flower found in the wetter areas of the island.
Narrow-leaved Sagittaria. Another water loving plant.
Here are two of the many flowers we saw today. Both of these were found in the freshwater ponds located in the swale areas of the barrier island. The flower to the left is known as Marsh Pink. The one to the right is Narrow-leaved Sagittaria.
The yellow vine called “Love Vine”; correct name is Dodder.
It is good to see bees on the island.
This orange-yellow stringy vine is called “Love Vine” but there is not much love here; this is a parasitic plant called Dodder. This is the first we have seen of it this year and expect to see more. Many residents on the island believe it to be an non-native invasive plant but it is actually a native and quite common out there. I have also seen it in the north end of Escambia County.
We did see a few bees today and this is a good sign. There have been reports in recent years of the decline of our native bees and the impact that has had on gardening and commercial horticulture. In addition to seeing bees Paul and I also came across the famous yellow fly. These were encountered near the marsh on the sound side of the island. Loads of fun there!
The “bed” made by an unknown animal that has been frequenting this location all year. Photo: Rick O’Connor
This scat pile was near the location of the “bed” and along the drag marks made by this animal.
If you have been following this series since we began in January you may recall the strange “bedding” and drag marks we have encountered near the marsh (you can read other issues on this website). I have seen these drag marks, and apparent bedding areas, every month except last. I showed them to Paul and we are still not sure what is making them. Again, whatever it is seems to move from one body of water to another. We cannot find in foot tracks to help identify it… but we will!
The photo to the right is of a large scat pile approximately 15-16” across. It was relatively fresh and contained crab and shrimp shell parts. Not sure if it was left by the same animal that continually makes the drags but was in the same location so…
The pretty, but invasive, beach vitex. Photo: Rick O’Connor
Many of the plants on our barrier islands are blooming now, and so is this one. This is Beach Vitex (Vitex rotundifolia). It is an invasive/not-recommended plant. Currently we are only aware of 22 properties in Escambia County that have it. Sea Grant is currently working with the SEAS program at the University of West Florida to assist in removing them. If you believe you have this plant and would like advice on how to remove contact your local Sea Grant Agent at the county Extension office.
Bats are extremely beneficial, but they can be unwelcome guests when they choose to roost indoors, like this evening bat. Photo credit: LeiLani Davis.
Bats typically sleep during the day in natural structures such as trees and caves. In areas with few natural roost structures, bats may instead choose to spend their days in buildings.
Bats are beneficial because each bat consumes hundreds of insects per night. Bats save farmers billions of dollars annually by substantially reducing the abundance of insect pests. However, they can be unwelcome guests when they choose to live in buildings. The safe, humane, effective way to coax a colony of bats out of a building permanently is through a process called an ‘exclusion’.
A bat exclusion is a process used to prevent bats from returning to a building once they have exited. It is accomplished by installing a temporary one-way door. This one-way door can take many forms, but the most tried-and-true is simply a sheet of heavy plastic mesh screening (with small mesh size) attached at the top and along both sides of the sheet, but open on the bottom. The one-way door should be attached over each of the suspected entry/exit points bats are using to get in and out of the building.
It is illegal to harm or kill bats in Florida, but exclusions from buildings are allowed if you follow practices recommended by the Florida Fish and Wildlife Conservation Commission (FWC). According to Florida law, all bat exclusion devices must be left in place for a MINIMUM of 4 consecutive nights with temperatures above 50 o F before each entry point can be permanently sealed to prevent re-entry by bats. Also, it is unlawful in Florida to attempt to exclude bats from a building between April 15 and August 15, which is bat maternity season. This is when female bats form colonies and raise young that are unable to fly for their first few weeks of life. If bats were excluded during this time period, young bats (called pups) would die indoors.
For more information on how to conduct a bat exclusion, check out this video that features interviews with bat biologists from the University of Florida, FWC, and the Florida Bat Conservancy: How to Get Bats out of a Building.
Remember, bat maternity season in Florida runs from April 15 to August 15. If you have a colony of bats roosting indoors that you want to exclude, you must either act quickly or else wait until the middle of August to coax them out.
Digital devices have proliferated like kudzu in July, and new user applications for these devices are as common as armadillos. Untold hours and dollars are being spent by couch potatoes to defend artificial worlds from dragons, zombies and other imaginary invaders.
Meanwhile, real exotic aliens from air potatoes to monitor lizards are invading Florida.
Don’t panic; there is some good news. A group of new applications that can help citizen scientists identify, locate and manage invasive plant and animal species in Florida is available for free.
The first line of defense is identifying and mapping new occurrences of invasive species. Many, if not most, new infestations were established before anyone noticed or cataloged them, and effective control strategies depend on knowing the extent of new infestations.
The Early Detection & Distribution Mapping System (EDDMapS) has been available at http://www.eddmaps.org since 2005. In the words of its developers, Charles Bargeron and David Moorehead of the University of Georgia’s Bugwood Network, the system was designed to: “develop more complete local, state and regional level distribution data of invasive plants, identify “leading edge” ranges of new invasive threats, provide a means of implementing early detection and response, and help corroborate threats and refine invasive plant lists and management priorities.”
“IveGot1” was developed by this same group through a cooperative agreement with the National Park Service in cooperation with the Florida Fish and Wildlife Conservation Commission and the University of Florida Center for Aquatic and Invasive Plants. The application is now available on both Apple and Android operating systems. The app includes invasive plants and animals and allows direct reporting of sightings as well as back ground information on Florida’s most common invasive species.

At least two other apps useful for invasive species management are also available. “Invasive Plants in Southern Forests” is adapted from the US Forest Service book of the same name. This publication is available for download at http://www.srs.fs.usda.gov/pubs/gtr/gtr_srs062, but it’s a big file (33MB). In addition to its ID function, the app includes appropriate control methods for the over 100 invasive trees, shrubs, vines, grasses and forbs described. As of now, this application is only available for the iPhone platform.
The second app is for Florida’s most widespread invasive animal. Although pythons may be our most infamous invasive animal, they don’t have the distribution of the wild hog. “Squeal on Pigs” combines a location app and educational information to support states’ efforts to control wild hog populations and reduce their impacts on streams and crops.
Maybe you won’t reach Destroyer level in the real battle on air potatoes and Florida’s other invasive species, but moving from Angry Birds to Squeal on Pigs will raise your power level as a Friend of Real Florida.
Florida Black Bear visiting an easy food source. Photo by Jennifer Bearden
Florida Black Bear are the largest land mammals in the state of Florida. At birth they are smaller than a soda can but they quickly grow up to 250-400 pounds for males and 125-250 pounds for females. Even though black bears are large animals, they are not fierce killers nor are they cute and cuddly. Bears are like most other wildlife; if you don’t bother them, they won’t bother you.
In 1974, bear population numbers were extremely low and the Florida Black Bear was listed as a state threatened species. Today, we have increased bear population numbers 10 fold to about 3,000 statewide.

As urban areas have expanded into bear habitat, the number of bear/human interactions has increased. Bears are omnivorous with 80% of their diet coming from plants. Bears are fairly intelligent creatures that forage for easy food sources. Urban areas tend to attract nearby bears with food sources such as garbage containers, pet food dishes, and bird feeders. Bears become accustom to food sources near humans and lose some fear of humans and may even bluff charge humans to defend their food source. The best way to prevent this is to remove food sources.
Clean BBQ grills and store them in a secure building when not in use.
Take garbage to the curb the morning of pickup instead of the night before.
Store garbage cans in a sturdy building or other secure area.
Feed pets inside and store pet food securely.
Protect gardens and trees with electric fencing.
Hang wildlife feeders out of reach of bears and take them down if bears are in the area.
It is illegal to feed bears in Florida (Florida Administrative Code 68A-4.001(3)). In addition to being illegal, it isn’t smart. Feeding bears intentionally or unintentionally increases the likelihood of human injury, property damage and bear injury or death.
So what do you do if you encounter a bear?
Remain calm and don’t run!
Don’t approach the bear, instead give it space to retreat.
Back away slowly without looking the bear in the eyes.
Speak to the bear in a calm voice.
Bring children and pets inside.
Find a safe place then make a lot of noise to let the bear know it isn’t welcome – yell, bang pots and pans, raise your hands high and stand tall to scare the bear away.
