Natural Area Weeds: Old World Climbing Fern (Lygodium microphyllum) (SSAGR21/AG122)

Figure 3. Leafy branches (pinnae) of Old World climbing fern are 2–5 inches long with several pairs of leaflets (pinnules).Native to Africa, Asia, and Australia, Old World climbing fern (OWCF) is a newcomer to Florida that has spread at an alarming rate since its introduction. The Florida Exotic Pest Plant Council considers Old World climbing fern to be invasive. It’s also regulated by laws of the Florida Department of Agriculture and Consumer Services (FDACS) as a Florida Noxious Weed and by the United States Department of Agriculture (USDA) as a Federal Noxious Weed. It may be the most serious threat to Florida’s natural areas. This 6-page fact sheet was written by Kenneth A. Langeland and Jeffery Hutchinson, and published by the UF Department of Agronomy, February 2013.

Florida's Established Arthropod Weed Biological Control Agents and Their Targets (ENY853/IN779)

Figure 2. Adult Lilioceris cheni.Around 5% of the plant species deliberately introduced into Florida for crop production and horticultural uses have invaded sensitive aquatic and terrestrial natural areas as well as improved pastures. One of the reasons they become invasive is they lack the natural enemies that limit their reproduction. Biological control reunites these natural enemies (usually arthropods) with their host plants to selectively weaken and suppress the invasive weeds. This 3-page fact sheet was written by J. P. Cuda and J. H. Frank, and published by the UF Department of Entomology and Nematology, October 2013.

Wildland-Urban Interface: Key Issues (FOR202/FR264)

small group of people looking at a mapA result of the influx of new residents to the South is an expansion of urban areas into forests and other natural areas, creating areas referred to as the wildland-urban interface. Interface issues of most concern vary from state to state, but some key issues are consistent across the South. the US Forest Service conducted a series of focus groups in 2000. Key issues gleaned from those focus groups and other related sources are described in this 5-page fact sheet written by L. Annie Hermansen-Baez, Jennifer Seitz, and Martha C. Monroe, and published by the UF Department of School of Forest Resources and Conservation, February 2013.

A Multi-Disciplinary Review of Current Sea-Level Change Research in Florida (TP193/SG125)

wordleSea-level rise is an issue of paramount importance for the state of Florida due to its lengthy coastline, low relief, high coastal population density, ecologically and economically vital beaches, estuaries, and wetlands, and porous limestone geology. The rate of sea-level rise in Florida generally follows the global average (~3 mm per year) and is slowly gaining public attention as a significant threat to the natural and socioeconomic future of the state. This 18-page multi-disciplinary review provides an annotated bibliographic summary of current peer-reviewed literature regarding sea-level rise in Florida. Written by Anna Cathey Linhoss, Lisa Gardner Chambers, Kevin Wozniak, and Tom Ankersen, and published by the UF Department of Sea Grant, February 2013.

Grass Carp: A Fish for Biological Management of Hydrilla and Other Aquatic Weeds in Florida (BUL867/FA043)

Figure 2. A mature grass carp, highly effective in controlling Hydrilla and many other noxious aquatic weeds.Abundant growth of aquatic plants causes serious problems in ponds, lakes, rivers, and irrigation and drainage throughout Florida. In some situations, native aquatic plants become weeds, but most often exotic plants introduced from areas outside the state flourish under the favorable growing conditions found in Florida. Long-term economical solutions to Florida’s aquatic weed problems have been elusive and there is a need for control techniques to alleviate aquatic weed problems. This 6-page fact sheet provides information on a biological method, the grass carp, for management of some of Florida’s aquatic weed problems. Written by David L. Sutton and Vernon V. Vandiver, Jr., and published by the UF Department of Fisheries and Aquatic Sciences, November 2013.

Tips for Integrating Land and Wildlife Management: Deer in Ranchlands (WEC330/UW375)

Figure 1. What often limits deer populations in Florida’s ranchlands is the availability of nutritious foods.In addition to having generally low-quality foods, ranchlands often have a low diversity of food sources, further reducing the quality of habitat for deer. Ranchland management for deer should therefore focus on providing a diversity of abundant, high-quality foods. This 2-page fact sheet provides some deer habitat improvement tips that focus primarily on raising the quality of deer forage but that also will help you grow better cover by improving plant diversity and productivity.

Natural Area Weeds: Skunkvine (Paederia foetida) (SSAGR80/WG208)

Figure 1. Skunkvine growing over native shrubs.Native to eastern and southern Asia, skunkvine is an invasive plant species introduced to the USDA Field Station near Brooksville before 1897. It has been included on the Florida Exotic Pest Plant Council List of Invasive Species as a Category I, defined as “species that are invading and disrupting native plant communities in Florida.” It was added to the Florida Noxious Weed List in 1999, making it illegal to possess, move, or release in Florida.

Freshwater Turtles of Belize (WEC328/UW373)

Figure 2. Hicatee (Dermatemys mawii) maleBelize, a country rich in natural resources and diverse wildlife, is home to nine species of freshwater turtles. Among these is the critically endangered hicatee, which has been eliminated in most of its range as a result of hunting and habitat loss. Freshwater turtles live in rivers, creeks, and lagoons, and build their nests on the banks. They eat a variety of plants, aquatic vegetation, and fruits. However, little is known about Belize’s unique turtle species. This 2-page fact sheet will help people identify, understand, and conserve these treasured resources.

Tips for Integrating Land and Wildlife Management: Deer in Forests (WEC329/UW374)

Figure 1. What often limits deer populations in Florida’s forests is the availability of nutritious foods.Prized by hunters and wildlife enthusiasts alike, white-tailed deer are a popular species found throughout Florida. As such, they are often the focus of management for landowners, managers, and lessees who want to improve deer populations while maintaining other land uses such as timber production. This 2-page fact sheet provides some deer habitat improvement tips that focus primarily on raising the quality of deer forage but that also will help you grow better cover by improving plant diversity and productivity.

Tips for Integrating Land and Wildlife Management: Quail and Timber (WEC331/UW376)

Figure 1. Quail prefer a highly interspersed, “crazy quilt” habitat.In Florida, changes in forest management practices during the past 50+ years have led to declines in quail habitat and populations. Important changes involve the use of fire and conversion of native forests to commercial pine plantations. A lack of fire and other disturbance has often led to closed-canopy forests with dense undergrowth that lack important quail habitat components. This 2-page fact sheet provides several quail habitat improvement tips that focus on diversifying the plant species and structural composition and increasing early successional communities dominated by herbaceous plants. Written by William M. Giuliano and Lauren Watine, and published by the UF Department of Wildlife Ecology and Conservation, January 2013.

Spiral Nematode, Helicotylenchus pseudorobustus (Steiner, 1941) Golden, 1956 (Nematoda: Tylenchida: Hoplolaimidae) (EENY544/IN973)

in973Spiral nematodes of the genus Helicotylenchus are among the most ubiquitous plant-parasitic nematodes worldwide. Helicotylenchus pseudorobustus is a species common in Florida and the southeastern United States and is frequently found associated with turfgrasses and other grass hosts in the region. On most plants, it is not considered particularly damaging, but recent research has shown that this species suppresses growth of certain turfgrass hosts. Seashore paspalum, a turfgrass used in tropical and subtropical regions, is particularly susceptible to infestation. This 4-page fact sheet was written by William T.
