Ecosystems and Species
	Citrus peelminer Marmara gulosa Guillèn and Davis (Insecta: Lepidoptera: Gracillariidae) (EENY415/IN985) The citrus peelminer is a dark-gray moth with mottled white and brown markings and about 4 mm in length. This moth is considered native in the United States, attacking willow. It is believed that a host-shift occurred to multiple non-native plants including all varieties of citrus and cerain ornamentals, such as oleander. Citrus peelminer has been reported to occur in low numbers in Florida and at least three Marmara species have been identified in the state. Recent evaluations of an experimental pheromone lure that is still under development by researchers at the University of California, Riverside have confirmed captures of citrus peelminer (Marmara sp.) in Polk County, Florida. This 3-page fact sheet was written by Lukasz L. Stelinski, and published by the UF Department of Entomology and Nematology, April 2013. http://edis.ifas.ufl.edu/in985
	Bagworm, Thyridopteryx ephemeraeformis Haworth (Insecta: Lepidoptera: Psychidae) (EENY548/IN981) North American bagworm can feed on over 50 families of deciduous and evergreen trees and shrubs. Severe infestations can damage the aesthetics and health of host plants, especially juniper and arborvitae species. Many of the preferred host plants do not grow well below the USDA hardiness zone 8A, but due to its wide host range, high female fecundity, and method of dispersal, bagworm can still be problematic in the Florida landscape. This 5-page fact sheet was written by Brooke L. Moffis and Steven P. Arthurs, and published by the UF Department of Entomology and Nematology, March 2013. http://edis.ifas.ufl.edu/in981
	Common Woody Plants of Florida Scrub Ecosystems (FOR305/FR373) The purpose of this fact sheet is to help identify a few of the more common woody plant species found in Florida’s scrub ecosystems. In the individual plant descriptions, words that appear in bold font are considered to be key field characteristics that will aid in identification of the species. This 14-page fact sheet was written by Lynn Proenza and Michael Andreu, and published by the UF Department of School of Forest Resources and Conservation, October 2012. http://edis.ifas.ufl.edu/fr373
	Key to Nine Common Smilax Species of Florida (FOR307/FR375) Identifying species found in Smilax the genus can be difficult because species resemble one another closely. One must be careful to use detailed descriptions in order to correctly identify a specimen. Smilax species are important because they can provide shelter and food for wildlife and have provided humans with medicine, food, and dyes. Twelve Smilax species are found in Florida. This 8-page fact sheet covers the nine more common species that one may encounter in the state. Written by Lynn Proenza and Michael Andreu, and published by the UF Department of School of Forest Resources and Conservation, January 2013. http://edis.ifas.ufl.edu/fr375
Water
	How Are the Reservoirs in the Apalachicola-Chattahoochee-Flint River Basin Managed? (AE497) Many uses of the Apalachicola-Chattahoochee-Flint river basin depend on how the US Army Corp of Engineers operates dam releases from the reservoirs when managing lake levels and downstream river flows and water levels. However, no single set of protocols equally suited to all uses and demands governs the reservoir releases. The purpose of this publication is to describe how the USACE manages reservoirs and dams in the ACF and how the waters in the basin are used. This 6-page fact sheet was written by Christopher J. Martinez, and published by the UF Department of Agricultural and Biological Engineering, March 2013. http://edis.ifas.ufl.edu/ae497
	Valuing the Ecosystem Services of Florida‹s Forest Conservation Programs: The Economic Benefits of Protecting Water Quality (FOR309/FR377) How much are Floridians willing to pay for water quality protection programs that include forest conservation? This 9-page fact sheet reports the results of a study to answer this question, using a benefit transfer approach. Written by Melissa M. Kreye, Francisco J. Escobedo, Damian C. Adams, Taylor Stein, and Tatiana Borisova, and published by the UF Department of School of Forest Resources and Conservation, April 2013. http://edis.ifas.ufl.edu/fr377
