When you think of snails, you probably aren’t thinking about scary monsters that have been unleashed to terrorize us all. I’m here to warn you that you should. The channeled apple snail (Pomacea canaliculata) is a known agricultural pest that competes with native snail species. In our area (panhandle Florida, Hurlburt Field to be exact) this snail is consuming unknown quantities of plant material in our sensitive wetlands. If you didn’t know, Hurlburt Field Air Force Base is one of the last places on Earth where the endangered reticulated flatwoods salamander (Ambystoma bishopi) can still be found, and this endangered salamander relies on healthy wetlands and ephemeral ponds for breeding.

So why should you worry? Just think about how snails eat: snails have a tongue (a radula) with teeth-like structures (denticles) they use to rasp or drill into their food. Normally, nobody would really worry about what snails are eating; they’re snails, right? But, here comes the scary part: when there are many snails, all eating and breeding and growing and eating, they consume a lot of material. And, what once was a cute little snail in your 10-gallon aquarium becomes a rampaging menace when you dump your tank out in the ditch next to your house and the snail escapes into the wild!

Ok, let’s be honest, it’s not like snails are running wild. I mean, they’re as slow as…well…snails. But what we believe began as a dumped aquarium pet some years ago has become a large population that is expanding into our wetlands. Although it is currently not found in our salamander breeding ponds (whew!), if we don’t do something to stop it, it soon could be. Here we are in Florida, where we have many examples of dumped or escaped animals that are breeding and growing and eating and breeding with no population control. This is one heck of a great example of an invasive species.

So, what are we going to do about this creeping, slimy, menace? Well, in our case, we called our invasive species contractor, and this year we will begin a labor-intensive project to control this species’ population on Hurlburt Field. We could use your support! Please use the IveGot1 app or EDDMaps to report local encounters with channeled apple snails. And, please DO NOT release non-native wildlife into the wild!

All along the roadsides and in home landscapes in summer, a profusion of fluffy pink blossoms are adorning trees known as mimosa, or Albizia julibrissin. This native of China was introduced to home landscapes in this country in the 1700’s to enjoy the fragrant, showy flowers and fine, lacy foliage. However, there is a dark side to this lovely tree. After blooming, it produces an abundance of pods each containing 5 to 10 seeds. Seeds can be spread by wildlife and water; this is evidenced by the appearance of mimosa trees along the roadways, streams and in our natural areas. The seeds can also remain dormant for many years, allowing the trees to keep sprouting long after the mother tree is gone.

Mimosa has been categorized as an invasive exotic plant in Florida by the University of Florida IFAS Assessment of Non-Native Plants in Florida’s Natural Areas. This designation means that the tree has not only naturalized, but is expanding on its own in Florida native plant communities. This expansion means that our native plants in natural areas get crowded out by mimosa as it reproduces so prolifically.

The Florida Exotic Pest Plant Council (FLEPPC) publishes a list of non-native plants that have been determined to be invasive. Click here for the most recent 2017 list!

The first step in controlling this pest plant is to remove existing plants in the landscape. Cutting it down at soil level and immediately painting the stump with a 25% solution of glyphosate or triclopyr should do the trick. Further details and control methods can be found here.

There are some native trees that make excellent alternatives to mimosa such as fringe tree (Chionanthus virginicus), silverbell (Halesia carolina) and flowering dogwood (Cornus florida).

Paddle Sports, the Key to Unlocking Ecotourism

In the Panhandle, we are blessed to be surrounded by some of the most beautiful and ecologically diverse, fresh & marine water bodies on the planet. Paddle sports are the perfect way to experience. So, get out and explore!

The oldest form of paddle sports, canoeing, is a great way to explore our natural waterways. Canoeing is an ancient mode of transportation that dates to the late 19th century. This simple recreational activity involves a single-bladed paddle and the canoe. It’s best to have friend along for the canoe ride to share the adventure, and to make paddling a breeze. Fun fact, canoeing and kayaking became part of the Olympic Games in the summer of 1936.

Kayaking is a bit different than canoeing. In contrast, kayaks were first built thousands of years ago in the Artic. The first kayaks were built of driftwood and animal skin. Kayaks can be made of many different materials today, and inflatable crafts are gaining popularity. The sitting position of the paddler on a kayak is more centrally located than with the canoe, with legs in front and the paddler facing forward. This activity also requires a double-bladed paddle. Sizes and shapes will vary depending on the region and size of the paddler. Kayaking is great to couple with diving, snorkeling, or even fishing. Sites for these activities can often range for miles off the coastline or in remote river locations with no launching or wading point nearby. Not only is kayaking much cheaper than purchasing and maintaining a power boat, it’s an environmentally friendly and healthy way to navigate waters.

Paddleboarding is the new kid on the block. This is essentially stand up paddle surfing. Paddleboarders stand up right on boards and use a single-bladed paddle to thrust through the surf. This activity is usually performed on the open ocean. It’s especially fun in Florida bays. A paddleboard that is approximately 14’ in length is usually the recommended size for most settings. There are various types of boards that can be used, including surfboards. Most paddleboards are made of fiberglass.

As with any watercraft, a buoyancy aid or life jacket should be equipped on the person always. The participant should also have various other measures of safety gear. A whistle for signaling for help should be with all participants. For kayakers and canoers, rope is helpful to have when someone needs rescue. A diving knife and water shoes can be helpful when bottom terrain poses a threat. Proper clothing such as a rash guard or wet suit will help protect from the elements. Don’t forget your sunscreen any time of year!

For more information on paddle sports and ecotourism please contact your local county extension office.

Wildlife Food Plots for North Florida

About this time each year the minds of sportsman and wildlife aficionados turn towards the planting of wildlife food plots for use by wildlife  in fall, winter , and early spring.  There are many factors to consider when planting a fall food plot if you want to be successful in the endeavor.  Food plots can be  an effective method of providing food sources for game birds, deer, rabbits, raccoons, and other species.  The size of food plots vary according to landowner preferences and the requirements of the target wildlife species, but usually they are a minimum of 1/2 to 1 acre in size, with a maximum of 5 acres.

Location is a an important consideration when planning the plot as the most effective plots typically are located adjacent to sanctuary or escape cover that provides security for wildlife.  Food plots that meander along edges of of two or there converging types of cover, such as the edge created where pine plantations, hardwood bottoms, and agricultural fields intersect, are very attractive to wildlife and provide natural travel corridors, in addition to providing a high nutrition food source.

Successful planting of your crop begins with soil sampling.  Having the proper pH in your food plot is of paramount importance.  A pH of 6.5 is ideal for winter annual grasses and legumes in North Florida.  As an Ag Agent I have seen more food plot disasters because a landowner did not take time to soil test than any other reason.  The soil test will also guide you in applying proper fertilization to optimize productivity of your food plots.  Food plots are expensive  to establish and you want to avoid needless mistakes such as poor fertility that will yield poor results.

Preparation of a good seedbed is also very important as is selection of seeds that are adapted to our area.  UF/IFAS has developed some excellent resources that will assist you in selecting forages that do well in our area such as, A Walk on the Wild Side: 2013 Cool-Season Forage Recommendations for Wildlife Food Plots in North FloridaAnother Excellent reference is Establishing and Maintaining Wildlife Food Sources.

Now is the time to make your preparations for planting your successful cool season food plot here in North Florida! hopefully you will have the experience of seeing and enjoying wildlife as pictured in photo 2 and photo 3!

For more information on planting successful food plots this fall, contact your local UF/IFAS Extension office.

Trying to Solve the Marine Debris Problem

Since the early 1970’s, when Chief Iron Eyes Cody shed a tear on a television commercial, we have been trying to reduce the amount of solid waste found along our beaches and within our waters.   Though numerous agencies and civic groups, led by the Ocean Conservancy, have held beach and underwater clean ups over the last few decades, the problem still exist.

 

However, we can say this – the problems have changed. Many groups collect data while they collect the debris to determine what, and how much, has been collected.  This information can give folks an idea of what the major issues are.  Because of this data, aluminum can pull-tabs and glass bottles are not as common as they once were.  Communities saw they were a large problem and either removed them from the market or developed ordinances that banned them from beaches – this is certainly a success story.  There are agencies and researchers who compile solid waste data to let people know what they are throwing away.  Once we know this, we can be more effective at reducing marine debris.

 

Solid waste is not just a problem for coastal beaches; it is problem throughout society. Landfills will fill up, and communities will then need another location, or a new method, to dispose of it.  Though the human growth rate has declined from 1.23% to 1.11% in the last decade, we are still growing and are currently at 7.5 billion humans on the planet.  Each human will require resources to survive and, thus, will generate waste that will need to be disposed of.  According to a paper published in 1990, humans were generating about 550 pounds of solid waste/person/year, which generated 1.3 billion tons of solid waste each year.  In 2009 that increased to 2.3 billion tons.

 

So how much of this solid waste is being recycled?

 

According to the U.S. EPA, 258 million tons of municipal solid waste was generated in the United States in 2014. 89 million tons (34%) was recycled.  This is an increase from the 30% reported in many environmental science textbooks 10 years ago and <20% 20 years ago.  Some states are doing much better than the national average, Washington reports they are now recycling 51.4% of their solid waste, and some nations are recycling more than 90% – so things are improving but there is room for improvement.

What is the situation in the Pensacola Bay area?

 

A non-profit organization called Ocean Hour cleans selected beaches for one hour every weekend.  The team coordinates volunteers to help collect the debris by providing buckets, tongs, and gloves; they also dispose of the waste.  Part of their mission is to provide data on what they are collecting so that the community is aware of what their largest problems are.  Based on their data the top three items reported by volunteers for each year were:

 

Year #1 Item #2 Item #3 Item
2015

 

Cigarette butts Food wrappers Plastic bottles
2016 Plastic bottles Aluminum cans Cigarette butts

Foam

2017 (to date)

 

Cigarette butts Food wrappers Plastic and foam pieces

 

The graph produced from Ocean Hour’s data by Escambia County Division of Marine Resource Intern Ethan Barker, shows all of the items they have collected this year but the bulk of it is associated with smoking and eating. Marine biologist and artist Shelly Marshall used 1200 cigarette butts collected by the Ocean Hour team to create a 3-foot sea turtle she calls CIG.  She then used plastic bottles and plastic bottle caps, again collected by Ocean Hour, to create a 5-foot “bottle”nose dolphin called CAP.  Both of these pieces of marine debris art are displayed at different locations in the community, and at community events, to educate the public about our marine debris problems.

So what do we do about it?

 

That is really up to us. Again, agencies, researchers, and non-profits have been reporting on the problem for almost five decades now.  We will continue to produce waste, not much can be done there, but the question is what we will do with it.  The obvious answer is dispose of properly and recycle when we can.

 

Cigarette Butts

  • If you are a smoker, please dispose of your cigarette butt properly. There are “pocket ash trays” some folks use to keep the butt with them until they can find a place to dispose of it.

Food Wrappers – Foam

Much of the debris is related to eating – wrappers, plastic film, foam cups, straws, etc. Much of what we find is associated with this activity.

  • You can use your own cup and not the foam cups provided by food establishments
  • You can bring your own container to take leftovers home
  • If you have to purchase food and drink with all of the wrappers and foam, and I understand that there are times you must, then do your best to dispose of properly.

Ocean Hour will continue their efforts to remove the debris from area beaches. If you can, volunteer to help now and then.  You can find their schedule at https://www.oceanhourfl.com/.

 

If Ocean Hour is not conducting a clean up in your area, consider having your own. The Ocean Hour team can assist with the logistics of how to conduct one.

 

Again, we are not going to stop waste production – but maybe we can do better with waste disposal.

With Hurricane Season Approaching, Are You Prepared for an Evacuation?

Hurricane season begins this year on June 1st and ends November 30th. As Floridians, we face the possibility of hurricanes each year. This simply goes with the territory. During these months, it’s important to plan for the threat of a hurricane, and at the same time hope, it never happens.

First and foremost, you may be asked to leave your home in emergency conditions. Emergency management officials would not ask you to do so without a valid reason. Please do not second guess this request. Leave your home immediately. Requests of this magnitude will normally come through radio broadcasts and area TV stations.

The most important thing to keep in mind is to have your own, up to date plan for a possible evacuation. The University of Florida has developed, “The Disaster Handbook” to help citizens plan for safety. The handbook includes a chapter dedicated to hurricane planning. The chapter can be downloaded in pdf at http://disaster.ifas.ufl.edu/chap7fr.htm.

Utilizing the 15 principles below will assist you in your evacuation planning efforts:

  1. Know the route & directions: keep a paper state map in your vehicle. Be prepared to use the routes designated by the emergency management officials.
  2. Local authorities will guide the public: Stay in communication with local your local emergency management officials. By following their instructions, you are far safer.
  3. Keep a full gas tank in your vehicle: During a hurricane threat, gas can become sparse. Be sure you fill your tank in advance of the storm.
  4. One vehicle per household: If evacuation is necessary, take one vehicle. Families that carpool will reduce congestion on evacuation routes.
  5. Powerlines: Do not go near powerlines, especially if broken or down.
  6. Clothing: Wear clothing that protects as much area as possible, but suitable for walking in the elements.
  7. Disaster Kit: Create a kit complete with a battery powered NOAA weather radio, extra batteries, food, water, clothing and first aid kit. The kit should have enough supplies for at least three days.
  8. Phone: Bring your cell phone & charger.
  9. Prepare your home before leaving: Lock all windows & doors. Turn off water. You may want to turn off your electricity. If you have a home freezer, you may wish not too. Leave your natural gas on, unless instructed to turn it off. You may need gas for heating or cooking and only a professional can turn it on once it has been turned off.
  10. Family Communications: Contact family and friends before leaving town, if possible. Have an out of town contact as well, to check in with regarding the storm and safety options.
  11. Emergency shelters: Know where the emergency shelters are located in your vicinity.
  12. Shelter in place: This measure is in place for the event that emergency management officials request that you remain in your home or office. Close and lock all window and exterior doors. Turn off all fans and the HVAC system. Close the fireplace damper. Open your disaster kit and make sure the NOAA weather radio is on. Go to an interior room without windows that is ground level. Keep listening to your radio or TV for updates.
  13. Predetermined meeting place: Have a spot designated for a family meeting before the imminent evacuation. This will help minimize anxiety and confusion and will save time.
  14. Children at school: Have a plan for picking up children from school and how they will be taken care of and by whom.
  15. Animals and pets: Have a plan for caring for animals and shelter options in the event of an evacuation. For livestock, contact your local county extension office.

Following these steps will help you stay safe and give you a piece of mind, during hurricane season. Contact your local county extension office for more information.
