Do you have any exotic pets you can no longer care for? Would you like the opportunity to surrender those pets without any penalties or fines? Then join the Florida Fish and Wildlife Conservation Commission (FWC) and Gulfarium Marine Adventure Park for an Exotic Pet Amnesty Day on Oct. 3 in Fort Walton Beach.
This free event is open to the public and will be held in front of Gulfarium Marine Adventure Park, 1010 Miracle Strip Parkway SE, Fort Walton Beach. Admission to the park is not included. Surrendered animals will be accepted between 10 a.m. and 2 p.m. These animals will be checked by a veterinarian and made available for adoption by experienced individuals who are capable of caring for them.
Animals that will be accepted for surrender include reptiles, amphibians, mammals, birds, fish and invertebrates. Domestic animals, such as cats and dogs, will not be accepted. For each animal surrendered, individuals will receive two free admission passes to the Gulfarium.
Animals will be available for adoption after 2 p.m. Exotic pet adopters must be experienced and must have already applied and been approved by the FWC prior to the event. Potential adopters need to bring their acceptance letters with them. People can find adopter applications at MyFWC.com/Nonnatives. Becoming an adopter is free, but people are required to register a minimum of five days prior to the event to adopt an animal.
Experts from the FWC, Gulfarium Marine Adventure Park and other local organizations will be on hand with information about caring for exotic pets, responsible pet ownership and potential ecological impacts of invasive species in Florida. Families can enjoy the opportunity to see several species of exotic animals and participate in crafts and games.
For additional information about this event, call the FWC’s Exotic Species Hotline at 888-Ive-Got1 (888-483-4681). Exotic pet owners who cannot attend this event may call this number for assistance in finding a new home for their animal.

Vampires of all types and genetic modifications are hot topics these days, and a common, but uncommon looking and acting Florida weed may have combined the two subjects. Dodder, a native invasive, parasitic plant, reproduces by seed but does not have enough leaves or chlorophyll to feed itself. Its thin, golden vines and tendrils must attach to a host plant in the seven to ten days it takes the plant to exhaust the carbohydrates in its small seed. Once dodder attaches to a plant, it connects to the inside of the host using small structures called haustoria which press into the stem and begin to draw nutrients from the host. At this point the dodder roots atrophy.
Single dodder plants are not a big issue, but once enough plants build up in an area large mats of vines can reduce growth and vitality of the host. (See photo) Frequently, the pest has reached this stage before it’s noticed, leaving the problem of treating a rootless, nearly leafless plant that is wrapped around a more desirable plant. Not only are the typical routes of herbicidal entry minimized, the hosts are at as much risk as the pest. Hand removal may be practical in small outbreaks, but the plant can reemerge from any small piece left attached to the host. In most cases, the solution is to destroy the host and the dodder and apply a pre-emergent herbicide to stop germination from any seeds remaining in the soil.
What about the GMO angle?
Work published last year in the journal Science by Jim Westwood of Virginia Tech reveals the dodder plant exchanges messenger RNA with tomato and Arabidopsis plants when it extracts the juices from the host plant. Scientists speculate this exchange of genetic material makes the host plant less resistant to attack by the parasite and that this holds promise for learning more about controlling other parasitic plants.
If plants are exchanging messenger RNA, a critical part of protein and gene synthesis, what other genetic exchanges are occurring naturally without our knowledge? Scientific progress hinges on unpredictable events and sources. Learning more from a “vampire weed” that has no easy means of control may be one of those.

Cogongrass seedheads are easily spotted this time of year.

We are well into spring and a wide variety of plants are showing off their colorful blooms. As lovely as most of the blooms are, some springtime colors are an unwelcome sight. Such is the case with the showy, white seedhead that is produced by Cogongrass (Imperata cylindrica). The presence of Cogongrass – a highly aggressive, invasive, perennial – in Florida is not news; it has been in Florida since at least the 1930’s. However, the white seedhead that it produces in the spring makes it easier to locate and identify. When the seedhead is not present, the somewhat boring looking grass has the ability to blend in with its surroundings. This makes it harder for un-expecting landowners to identify the new/small infestations which are much easier to eliminate than are larger, well established infestations.
While cogongrass spreads primarily by rhizomes the seedheads can make new infestations easier to find.

Controlling cogongrass is not easy but it is necessary. If left uncontrolled cogongrass will continue to aggressively spread, displacing other desirable vegetation. Generally speaking, control is a multi-year process. Because the specific recommendations for controlling cogongrass can vary somewhat by situation it is highly advisable that you contact a UF/IFAS Extension Agent in your county if you suspect that you have cogongrass on your property.
The following description of cogongrass from UF/IFAS Center for Aquatic and Invasive Plants should help you identify cogongrass, even if the seedheads are gone.
“Cogongrass is a perennial that varies greatly in appearance. The leaves appear light green, with older leaves becoming orange-brown in color. In areas with killing frosts, the leaves will turn light brown during winter months and present a substantial fire hazard. Cogongrass grows in loose to compact bunches, each ‘bunch’ containing several leaves arising from a central area along a rhizome. The leaves originate directly from ground level and range from one to four feet in length. Each leaf is 1/2 to 3/4 of an inch wide with a prominent, off-center, white mid-rib. The leaf margins are finely serrated; contributing to the undesirable forage qualities of this grass. Seed production predominately occurs in the spring, with long, fluffy-white seedheads. Mowing, burning or fertilization can also induce sporadic seedhead formation. Seeds are extremely small and attached to a plume of long hairs.”
This is the time of year when cogongrass is the easiest to identify. Take advantage of this opportunity to locate new infestations and work with your county agent to develop a control plan. Once a plan is in place, follow it to the end. Stopping after the first year will practically ensure that control will not be achieved.
