Palmer amaranth can reach heights up 10 feet and signal real trouble for hunters, farmers, and land managers. Loaded with numerous small seeds, mature plants and “offspring” are difficult to control. Photo Courtesy of University of Florida / IFAS
Deer feeders are common in North Florida, and “deer corn” is sold in multiple markets. Cross-roads convenience stores sell it in plain brown bags and big box stores in town sell it in camouflage bags with three color pictures of giant bucks on the front. With the high price of corn in 2012, many hunters saved a few dollars buying “combine run” corn from local farmers or corn screenings from grain elevators. The corn’s no different, however, either product can contain weed seed, especially Palmer amaranth. These weeds can mean big trouble for farmers and hunters.
Palmer amaranth is a species of pig weed, but it’s not your granddaddy’s “careless weed”. It’s taller than either red root pigweed or spiny pigweed, and is becoming resistant to several herbicides, most notably glyphosate (“Roundup”). Amaranth seed are small and plentiful (1 to 1.5 millimeters in diameter) and easily can fit in the nooks and crannies of grain harvesting and handling equipment.
Palmer amaranth first true leaves have small notches on the end and can serve as an identifying characteristic. Photo Courtesy of University of Florida / IFAS.
Once Palmer amaranth seed make it into a deer feeder, there’s a huge opportunity for seedlings to take root in places under the radar of typical scouting and control measures. If these seedlings are herbicide resistant, you’ve done far more harm to the landowner than any savings on corn cost can offset. Conservative estimates indicate herbicide costs have at least doubled due to herbicide resistant weeds. Do your local farmer a real favor; scout and control weeds coming from your deer feeder.
Further information on identifying and controlling Palmer amaranth is available from your county Extension agent or at http://edis.ifas.ufl.edu/ag346
Feeding corn to deer and turkey is permitted by the Florida Fish and Wildlife Conservation Commission as long as the following restrictions are met. “Resident game and wild hogs may be hunted in proximity of year-round game-feeding stations on private lands, provided the feeding station has been maintained with feed for at least six months prior to taking resident game,” and “Wild turkey may not be taken if the hunter is less than 100 yards from a game feeding station when feed is present.” See General Information regarding Feeding Game at http://myfwc.com/hunting/regulations/general-information

It seems everyone in the Panhandle is talking about the invasive lionfish. This non-native member of the scorpionfish family was first seen in U.S. waters in 1989 near Ft. Lauderdale. Over the last two decades, much has been learned about the biology and potential impacts of lionfish in our waters; For additional background information you can read more at these websites http://myfwc.com/wildlifehabitats/nonnatives/marine-species/lionfish and http://escambia.ifas.ufl.edu/marine/2012/08/17/the-invasion-of-the-lionfish
This past October, the Florida Fish and Wildlife Conservation Commission held the first state lionfish summit in Cocoa Beach. Researchers, fishery managers, divers, fishermen, and the general public received research updates, discussed current issues, and provided input regarding future management needs. Here are a few of the interesting highlights from the summit.

What are the potential problems?
- Several theories on how lionfish were initial released into state waters have been suggested. However, research results now indicate a single introduction of lionfish in Florida initiated the invasion into the Western Atlantic presumably from just a few aquarium specimens.
- Sixty-thousand lionfish continue to be imported into the state each year.
- Compared to native Pacific population, Florida densities of lionfish are much higher; 400 fish/hectare in Florida compared to 80 fish/hectare in the Pacific. On average, invasive Atlantic Lionfish individuals are larger than the native populations in the Pacific basin.
- Studies from Pensacola showed that lionfish population has doubled annually since 2010 and lionfish densities are highest on artificial reefs.
- Invasive lionfish have no natural predators and may spawn 30,000 – 40,000 eggs every 2 to 4 days.
- Another potential problem reported are records of lionfish entering the Loxahatchee and Indian Rivers; indicating that they are able to move into brackish water.
What are the negative impacts?
Young lionfish feed primarily on crustaceans and when they are older they prey on reef fish. Research and stomach analysis indicate 70 different reef fish species as potential prey. Lobster fishermen in the Keys found lionfish are the leading by-catch species and have reduced lobster harvest by as much as 50%. Another study indicates lionfish on natural reefs they prefer blennies. However, on artificial reefs they feed on small snappers, sea bass, and groupers. Finally, an interesting study compared primary reef predators. Reefs with only grouper there was a 36% decrease of juvenile fish while reefs with lionfish the decrease was 94%.
What can be done?
Several reports indicate that collecting tournaments are effective; Lad Akins of Reef Environmental Education Foundation (www.reef.org) reported a 69% reduction of lionfish from one event in Key Largo. Another study had similar results but indicated that some spear fishermen were more successful than others, suggesting training may be required to increase efficiency.
Other reports indicate that work where native fish were introduced and conditioned to consume lionfish have led these native predators to follow and even bite divers thinking that “free food” may be available; it was suggested that this idea not be pursued.
Locally, lionfish rodeos sponsored by Emerald Coast Reef Association occur frequently in Okaloosa County. Escambia County Marine Resources hosted a pilot event this summer. Escambia will begin a full lionfish control program in 2014. If you have questions or comments, please contact your local UF/IFAS natural resource or Sea Grant Extension Agent.
Please note: UF/IFAS and Florida Sea Grant does not organize volunteers to participate in local lionfish control events; this is done by independent community groups. UF/IFAS and Florida Sea Grant provides this information about food safety concerns associated with eating lionfish. Click here for more information.

Beach vitex expands its woody rhizomes aggressively; it can actually grow over sidewalks and driveways.
It’s actually a pretty plant, this Beach Vitex (Vitex rotundifolia), and it is very good at stabilizing eroding dunes. In the 1990’s, the state of South Carolina planted this shrub to help restore dunes lost during hurricanes. It was selected because of salt tolerance, production of woody rhizomes (runners) that extend over 60 feet to trap sand, and the beautiful purple flowers that attract beneficial insects; it seemed perfect! However, folks along the Atlantic coast had no idea how invasive it would become a few years later. Residents discovered that it chokes out many of the native species such as sea rocket and sea oats producing an area of only this plant.
It is now causing problems for sea turtles. As you can see in some of these photos, the plant grows over the fore-dune, blocking access for nesting. Beach Vitex grows so aggressively that during the 60 day incubation time many turtle nests are overgrown, entrapping the hatchlings. Some have been found dead, entangled within the rhizome mats. The Beach Vitex “invasion” has become so bad that South Carolina developed a Vitex Task Force to deal with the problem.
This yard on Pensacola Beach has become overrun by vitex.
Is this a problem for Florida?
According to the records the Early Detection and Distribution Mapping System EDDmaps.com, Beach Vitex is distributed northward to the Chesapeake Bay area and south to Jacksonville. It is found in coastal Alabama and there is one record of the plant in Escambia County.
With so few records in Florida it is not currently listed as an invasive species in our state and there is no program set up to control it. However the Sea Grant Extension Agent in Escambia County, Rick O’Connor, was alerted in 2013 that vitex was in Gulf Breeze, Florida (Santa Rosa County) and possibly on Santa Rosa Island (Escambia County).
Please circulate to area residents to provide visual identification of Beach Vitex. Contact your Extension Office for control options and help reduce it’s impact on native species.
A “Wanted Poster” was developed by O’Connor to post in the coastal communities of Escambia and Santa Rosa counties to see if the plant was more common than the records indicated. At this time, six properties on Santa Rosa Island have confirmed records of Vitex and two more will be surveyed soon. The wanted poster program was published in the local newspaper which reached the east coast of Florida. Reports from that coast indicate that it has extended south into Volusia County. Okaloosa/Walton Sea Grant Agent Brooke Saari is posting the wanted poster in those counties to see if the plant has reached their coasts.
The owner of this yard mowed the vitex. However the woody rhizomes are still present. They will need to either dig this up or use multiple chemical applications to completely remove.
Anyone along the coast of the Florida Panhandle who feels they may have this plant can contact either Rick O’Connor (850-475-5230; roc1@ufl.edu) or Brooke Saari (850-689-5850; bsaari@ufl.edu) and we can confirm identification. The plant is not currently listed as invasive in our state and removal is not required. However, based on the experience in the Carolina’s and other invasive species, if you wish to eradicate this plant doing so early is important. It is much less labor intensive and less costly when there are few plants. If you do choose to remove it please contact your local Extension office first. We can provide methods of successful removal. We would also like to photograph and log the record on EDDmaps.

Summer is a time to bask in the sunshine for many of Florida’s wildlife species.
Each of Florida’s seasons are characterized by a variety of amazing and beautiful wildlife activities. Below is a list of some notable native wildlife behaviors occurring in July and August around the state.
July
Birds
- Shorebird migration starts in mid-July, peaking in August.
- Swallow-tailed kites begin gathering as do purple martins and tree swallows in preparation for migrating south for the winter.
- Look out for nesting shorebirds, and keep your vehicles and dogs from disturbing them.
Reptiles
- Later this month, young alligators and crocodiles will begin to hatch.
Mammals
- Baby raccoons, foxes, armadillos, possums, and bobcats leave dens and begin following parents.
Plants
- Sea oats flower along the Atlantic and Gulf.
- Scrub morning glory and butterfly weed begin to bloom.
Of Special Historical Note:
August
Birds
- First flocks of blue-winged and green-winged teal arrive to winter on Florida lakes and wetlands.
- Yellow warbler migration begins.
Mammals
- Two-year old black bear cubs will wean from their mothers.
- Short-tailed shrews will begin a second round of breeding for the year.
Reptiles
- Young sea turtles are hatching so avoid marked sea turtle nests and turn off lights to reduce light pollution.

Insects
- Thousands of great southern white butterflies can be seen migrating through coastal areas.
Invertebrates
- Corals along the Keys spawn at the full moon
More of these “happenings” for the calendar year can be found at the University of Florida’s Wildlife Extension Website: Wildlife Happenings.
Also at the Wildlife Extension website are a number of interesting resources to learn not only about our native wildlife, but our non-native/invasive wildlife as well. For example: can you distinguish between the invasive Cuban treefrog and our native species? The Cuban treefrog is well established in central and south Florida and has been documented in Bay and Leon Counties in north Florida. Be on the lookout for this alien treefrog!
Natural habitats invaded by Cuban Treefrogs include pine forests, hardwood hammocks, and swamps. In urban and suburban settings they are most commonly found on and around homes and buildings, and in gardens and landscape plants – Image by Dr. Steve A Johnson 2005.
On the flip side, did you know that our “own” American Bullfrog is invasive in other countries throughout the world? Also, current research is investigating the observations that mating calls of some non-native frogs may interfere with the dynamics of native frogs’ calling behavior. These and other up-to-date facts can be found in the UF/IFAS Invader Updater newsletter. The current issue has articles on the suckermouth catfish, Cuban treefrog, lampreys, and the recent record-sized python caught in south Florida.
Focusing back to our own unique native wildlife, you may find, as I did, this UF website of Frogs & Toads of Florida of interest to you. It has beautiful pictures of each species as well as an audio recording of its distinctive call. So, turn up the volume on your speakers and listen to a sampling of the chorus that serenades Floridians each night. Click Here to listen to the call of the Squirrel Treefrog.

National Invasive Species Awareness Week: March 3rd – March 8th
March 10th: Palmer Amaranth (Palmer amaranth) & Nutria (Myocastor coypus):

Palmer Amaranth: Palmer Amaranth, a type of pigweed, is invading the Southeast. It is a very troublesome weed for us because it is fast growing, produces a lot of seed and easily develops herbicide resistance. Palmer is a summer annual weed that can grow up to 10 feet tall. Each female plant can produce up to 500,000 seeds. Populations of this weed have developed resistance to 4 different classes of herbicides, including glyphosate or “Round-Up”. There are other types of pigweed in Florida, such as spiny and redroot pigweed, so you must be able to positively distinguish Palmer Amaranth from others.
Here are the main differences:
1. Petioles (or stalks joining leaves to the stem) are as long or longer than the leaf blades.
2. The plant has long terminal inflorescence (cluster of flowers on top of the stem).
3. They have prominent white veins on the lower surface of the leaves.
4. They have hairless leaves.
5. They are faster growing than other pigweeds.
If you have identified palmer amaranth in your field, treat with glyphosate. If the pigweed survives, then quickly hand-weed the female plants as soon as possible. Even if just a few plants survive this year, next year you could have thousands more. Palmer Amaranth is very difficult to control but by employing sound IPM principles it can be managed. Refer to http://edis.ifas.ufl.edu/ag346 for identification and control measures.

Nutria: This large rodent resembles a beaver but has a round tail. They are originally from South America and were brought to the United States for the fur business. Nutria are completely vegetarian and feed on both land and aquatic plants. Their small forelimbs are used to dig out roots and rhizomes and they can eat their own weight in plants each day. Feeding occurs anytime but is most often at dawn and dusk. From their initial release in Louisiana they have spread all over the Gulf coast. There are reports of them in the Chesapeake Bay area, Ohio, and along the Oregon coast. They become sexually mature very quickly (4-9 months) and have a short gestation period (130 days). Breeding year around a single female can produce 2.5 litters each year so in a short period of time high numbers of nutria can completely clear a densely vegetated area. Another problem with them is their ability to burrow into dikes and levees, making them weaker. Their occurrence in Florida has been spotty, with 45 individuals being recorded. There are records in all Florida panhandle counties except Bay.
