Thinning Southern Pines – A Key to Greater Returns
Thinning is an important silvicultural practice that redistributes the growth potential of the site to the best trees. Diameter growth rates are maintained or increased on residual trees after thinning, which increases the return on investment from higher-value trees. Biologically, thinning accelerates stand development by favoring the tallest, best-formed trees over those that are diseased, overtopped, crooked, forked, or otherwise undesirable and likely to die on their own if left in the stand long enough. In addition, thinning provides periodic income, improves access for equipment, recreation and hunting, and creates a generally healthier stand. Thinning is also beneficial for wildlife, especially when combined with prescribed fire or herbicide use to control competing vegetation. By allowing more light to reach the forest floor, thinning promotes growth of plants important as food and/or cover for wildlife species. Landowners are encouraged to consult with or hire a professional forester to assist with thinning and other forest management activities.

Thousand Cankers Disease: A Threat to Black Walnut in Florida (FOR308/FR376)
Thousand cankers disease of walnut is a tree disease of the edible nut-producing and ornamental tree, black walnut. The first diseased trees were observed in New Mexico in the 1990s. The disease has since spread to most of the western states. Until 2009, diseased black walnut trees were only found outside of the natural range of black walnut, which occurs from the mid-Atlantic states to just west of the Mississippi River. In 2009, it was found near Knoxville, Tennessee; it has since spread to Pennsylvania and Virginia. It is possible that within the next decade this disease could naturally spread to Florida. However, if people continue to move TCD infested walnut logs from place to place, this disease could arrive in Florida tomorrow. This 3-page fact sheet was written by Don Spence and Jason A. Smith, and published by the UF Department of School of Forest Resources and Conservation, February 2013.

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

Classical Biological Control of Air Potato in Florida (ENY864/IN957)
Air potato was introduced to Florida in 1905. By the 1980s, its vines were growing in thickets, waste areas, and hedges or fencerows in many parts of south and central Florida. By 1999, it was recognized as transforming plant communities by displacing native species, changing community structure and disrupting ecological functions. The air potato leaf beetle is a rather large, orange-red Asian leaf beetle. It feeds and develops only on air potato. The USDA-ARS Invasive Plant laboratory in Fort Lauderdale acquired this beetle from China and has begun an ambitious release program aimed at controlling air potato. This 3-page fact sheet was written by T. D. Center and W. A. Overholt, and published by the UF Department of Entomology and Nematology, October 2012.

The Costs of Managing an Urban Forest (FOR217/FR279)
Urban forests provide benefits to society often referred to as ecosystem services: they improve human health, environmental quality, and local economies by increasing property values and aesthetics in communities. They help cities control storm water, reduce air pollution and energy costs, and offset carbon dioxide emissions. But urban forests also have “ecosystem disservices.” An accurate assessment of an urban forest’s costs can assist decision makers to better understand the role the forest plays in improving the well-being of the community. Identifying how funding is used can also help communities minimize costs and increase benefits. This 4-page fact sheet will review some of the types of costs associated with urban forests and present typical financial costs associated with urban forest management in the city of Gainesville, Florida.
