Payments for sequestering carbon in forests can be an important supplemental income source in the southern US which includes one-third of the contiguous US forest carbon stocks and supplies 16% of the world’s wood. It is difficult to understand the carbon market and certification options available to Florida forest landowners and the possible risks of participating in them. To address this need, UF/IFAS forest management specialists provide this overview of forest carbon markets in the United States as of 2014 and compare key features of the four major carbon offset certification options. This 9-page fact sheet was written by José R. Soto, Francisco J. Escobedo, and Damian C. Adams, and published by the UF Department of School of Forest Resources and Conservation, July 2014.

Waterhyacinth: Florida's Worst Floating Weed
Waterhyacinth is one of the world’s worst aquatic weeds and is Florida’s most intensively managed floating plant. Dense mats formed by this species interfere with human uses of water bodies and disrupt ecosystems by preventing penetration of light and oxygen into the water column. This attractive, free-floating aquatic plant grows throughout the year in southern Florida but often dies back during the winter in the northern parts of the state. Waterhyacinth is cultivated as a water garden and pond plant, but cultivation, sale, and possession of this noxious weed is prohibited in Florida. This 5-page fact sheet was written by Lyn A. Gettys, and published by the UF Department of Agronomy, September 2014.

Facts about Wildlife Diseases: Pseudorabies
Pseudorabies primarily affects swine, but cattle, sheep and other mammals are susceptible to infection. Humans are not at risk. The superficial symptoms of this viral disease resemble rabies symptoms, thus the name pseudorabies. Although eliminated in commercial animals, feral swine populations in the United States continue to circulate the disease and provide a reservoir for outbreaks. Texas, Oklahoma, Florida, and Hawaii all have dense populations of feral swine with a high prevalence of pseudorabies. Feral swine, therefore, pose a serious risk to commercial swine operations, livestock, companion animals, and wildlife.

Adaptation Approaches to Sea-Level Rise in Florida
There is consensus among the scientific community that climate change is occurring and will have far-reaching effects on our global ecosystems and human systems. In Florida, adaptation to climate change is occurring in both natural and human systems. As coastal communities prepare for sea-level rise, they can use several strategies to integrate natural adaptation processes into their planning processes. By taking a proactive approach to adaptation rather than a reactive one, communities will be able to better protect the resources upon which they depend. This 4-page fact sheet was written by Ondine Wells, Whitney Gray, and Paul Monaghan, and published by the UF Department of Agricultural Education and Communication, July 2014.

Alligator Abundance and Hydrology (2003–2013): What Long-term Monitoring Can Tell Us about Everglades Restoration
The American alligator is a powerful indicator for Everglades restoration. It responds clearly to environmental change and is easy and inexpensive to monitor. As top predators and ecological “engineers,” alligators affect nearly all aquatic life in the ecosystem. Thus, trends in alligator populations can tell us whether restoration projects are successful. Alligators may be monitored for both short-term responses (body condition) and longer-term responses to ecosystem change (abundance). This 3-page fact sheet discusses trends in alligator abundance. It was written by Rebecca G. Harvey, Jeff Beauchamp, Robin Bijlani, Frank J. Mazzotti, and Laura A. Brandt, and published by the UF Department of Wildlife Ecology and Conservation, July 2014.

Hydrellia fly parasitic wasp Trichopria columbiana Ashmead (Insecta: Hymenoptera: Diapriidae)
Trichopria columbiana is a parasitoid of Hydrellia fly species. Depending on the ecological role of the host species, it can have a positive or negative effect on biological control. Some Hydrellia species feed on the invasive aquatic weed hydrilla. After its introduction into the U.S. by the aquarium industry in the 1950s (Langeland 1996), various control methods, including biological control, were developed and used to manage infestations. Classical biological control studies were initiated in the 1970s, which led to the release of four insects in the U.S., two of which were the leaf-mining ephydrid flies, Hydrellia pakistanae and Hydrellia balciunasi. Despite successful establishment and range expansion of the Asian hydrilla leaf mining fly, Hydrellia pakistanae, population levels of the insect and associated plant damage have remained low. One of the potentially limiting biotic factors is parasitism by the native endoparasitic wasp Trichopria columbiana. This 6-page fact sheet was written by Byron R. Coon, Nathan E. Harms, Michael J. Grodowitz, Emma N.I. Weeks, and James P. Cuda, and published by the UF Department of Entomology and Nematology, June 2014.

Hydrilla tuber weevil Bagous affinis Hustache (Insecta: Coleoptera: Curculionidae)
Bagous affinis Hustache is a semi-aquatic weevil that feeds on the aquatic invasive plant Hydrilla verticillata (L.f.) Royle. The larvae of the weevil mine hydrilla tubers, and the adults feed on the submerged stems and leaves. The weevil was discovered during surveys for biological control agents for hydrilla in Pakistan in 1980 and was first introduced to the U.S. in Florida from India in 1987. This 5-page fact sheet was written by Emma Weeks, and published by the UF Department of Entomology and Nematology, June 2014.

Grass Carp, the White Amur: Ctenopharyngodon idella Cuvier and Valenciennes (Actinopterygii: Cyprinidae: Squaliobarbinae)
The grass carp, Ctenopharyngodon idella Cuvier and Valenciennes, was imported to the U.S. in 1963 as a biological control agent for hydrilla (Hydrilla verticilliata (L.f.) Royle) and other aquatic plants. Concerns of escape and reproduction, and the potential impacts that colonization of the fish could have on native flora and fauna led to research that developed a non-reproductive fish, which was equally effective in controlling hydrilla. In the warm waters of Florida, with abundant food, grass carp grow quickly at around 2 lbs/month or 0.91 kg/month and may achieve weights of 97 lbs (44 kg). Younger fish and female fish grow faster than older or male fish. Grass carp are the most effective biological control tool that has been identified for hydrilla.

Hydrilla Stem Weevil Bagous Hydrillae O’Brien
Bagous hydrillae O’Brien is a semi-aquatic weevil that feeds on the aquatic invasive weed Hydrilla verticillata (L.f.) Royle. Larvae of the weevil mine hydrilla stems and the adults feed on the stems and submerged leaves. This weevil was discovered during overseas surveys for biological control agents for hydrilla during the 1980s and was first introduced to the U.S. in Florida in 1991 after extensive host-specificity testing. This 5-page fact sheet was written by Emma Weeks, Jim Cuda, and Michael J. Grodowitz, and published by the UF Department of Entomology and Nematology, June 2014.

Hydrilla leaf mining flies (unofficial common name) Hydrellia spp. (Insecta: Diptera: Ephydridae)
http://edis.ifas.ufl.edu/in1034
Several native and introduced species of flies in the genus Hydrellia are important because they feed on hydrilla (Hydrilla verticillata L.f. Royle), an invasive aquatic plant that has been classified as a Federal Noxious Weed. Hydrilla has invaded aquatic ecosystems in Florida and across the U.S. Larvae of Hydrellia spp. mine the leaves of hydrilla. In Florida, there are four species that have been associated with the invasive aquatic weed hydrilla: two native species and two species that were introduced for biological control of hydrilla. The native species are Hydrellia bilobifera Cresson and Hydrellia discursa Deonier. The introduced species are Hydrellia pakistanae Deonier and Hydrellia balciunasi Bock. This 6-page fact sheet was written by Emma Weeks and James Cuda, and published by the UF Department of Entomology and Nematology, April 2014.
