Conservation of natural resources requires investments of money, time, and effort by the government, businesses, landowners, conservation organizations, and the general public. Policies to conserve and manage natural resources should be based on a careful accounting of both the benefits and costs of conserving these resources. In a prior EDIS document, cost-benefit analysis and the role it plays in natural resources management and policy was discussed. This document extends that previous discussion by presenting more detailed information about how economists categorize the benefits of natural resources. This 4-page fact sheet was written by Elizabeth Pienaar, and published by the UF Department of Wildlife Ecology and Conservation, December 2014.

Water Issues in Florida: How Extension Can Facilitate Stakeholder Engagement and Involvement
This 6-page fact sheet is a brief description of recent discussions and policies surrounding water management, use, and quality in Florida. The goal of this publication is to provide brief, but clear, information about the trends in policies that can be used by Extension agents to increase educated conversations about water issues. Water in Florida is a contested issue, and Extension agents may be called upon as a source of unbiased information by the public. Having an understanding of important agricultural and natural resources issues in Florida, including water, can help facilitate conversation, raise awareness, and lead to informed decision making. Written by Erica Odera, Alexa Lamm, Tracy Irani, Hannah Carter, and Sebastian Galindo-Gonzalez, and published by the UF Department of Agricultural Education and Communication, December 2013.

The Role of Soil Management in Minimizing Water and Nutrient Losses from the Urban Landscape
Soil is the most important building block of a healthy, attractive landscape, serving many important physical, chemical, and biological functions. Soil provides a physical substrate for plant support and holds nutrients and water for plant use. It also facilitates groundwater recharge (water moving from surface water to groundwater) and provides long-term storage for organic matter. Soil also provides a habitat for microorganisms that aid in the transformation and availability of nutrients. Soil is an integral part of any ecosystem, but urbanization often changes soils in ways that negatively affect plant development. Soils in urban areas may have reduced water infiltration, resulting in increased runoff and increased potential for nutrient losses. Homeowners in urban areas often overcompensate for poor planting conditions by applying inappropriate amounts of fertilizer and water. These practices eventually lead to nutrient losses through stormwater runoff or soil leaching, and these lost nutrients negatively impact groundwater and ecosystems in nearby springs, streams, and water bodies.

Maximizing the Benefits of Reclaimed Water for Irrigating the Landscape and Protecting the Environment
Reclaimed water is water that has been treated in municipal wastewater facilities and is safe to use for designated purposes, including residential landscape irrigation. “Water reuse” is the term used to describe the beneficial application of reclaimed water. Approximately 663 million gallons of reclaimed water are used daily in Florida. Florida is a national leader in using reclaimed water, and in 2006 Florida’s reuse program received the first U.S. Environmental Protection Agency Water Efficiency Leader Award. Using reclaimed water in Florida meets a state objective for conserving freshwater supplies, and preserves the water quality of rivers, streams, lakes, and aquifers. This publication discusses the benefits of using reclaimed water to irrigate the landscape and explains how using reclaimed water helps to protect the environment.

Necropsies of Reptiles: Recommendations and Techniques for Examining Invasive Species
Captures and postmortem examinations, or necropsies, of invasive or nonnative animals may provide insight into the ecological impact of these invaders. Researchers should be able to perform necropsies when an opportunity arises to examine nonnative species for study. While the techniques described serve as a guide to necropsy of all reptiles, we focus on exotic species found in south Florida. South Florida provides prime habitat for invasive reptiles such as Argentine black and white tegu and Burmese python, and these species are used to describe our techniques. This 26-page fact sheet was written by Seth C. Farris, Michiko A. Squires, Frank Ridgley, Emma Lavergne, Mitchell Serota, and Frank J. Mazzotti, and published by the UF Department of Wildlife Ecology and Conservation, September 2013.

Invasive Species of Florida’s Coastal Waters: The Red Lionfish (Pterois volitans) and Devil Firefish (P. miles)
Two species of Indo-Pacific lionfish (Pterois volitans and P. miles) are the first reported non-native marine fish to become established in the Atlantic Ocean. Genetic studies indicate that lionfish in the Atlantic are likely all descendants of a few individuals, consistent with the widely held belief that lionfish were introduced into the Atlantic as a result of accidental or deliberate release of aquarium pets. Regardless of the method of introduction, the prolific spread of these invasive species in the Atlantic Ocean ecosystem is cause for concern.

Psilido, Boreioglycaspis melaleucae Moore (Insecta: Hemiptera: Psyllidae)
El árbol Melaleuca quinquenervia (Cav.) S. T. Blake (Myrtaceae), conocido como corteza de papel, es una especie invasora agresiva en varios ecosistemas del sur de Florida, incluyendo los Everglades. Melaleuca está considerado una plaga porque desplaza la vegetación nativa y degrada el hábitat de especies silvestres; además aumenta el peligro de incendios y puede causar problemas a la salud humana (Rayamajhi et al. 2002). El Departamento de Agricultura de los Estados Unidos (USDA) y el Servicio de Investigación Agrícola (ARS), bajo permiso federal y estatal, introdujeron el psílido Boreioglycaspis melaleucae en Florida en el Condado de Broward, en Febrero del 2002 como un agente potencial de control biológico de melaleuca.

Sri Lankan weevil Myllocerus undecimpustulatus undatus Marshall
Myllocerus undecimpustulatus undatus Marshall, the Sri Lankan weevil, is a plant pest with a wide range of hosts. This weevil spread from Sri Lanka into India and then Pakistan where many subspecies of Myllocerus undecimpustulatus Faust are considered pests of more than 20 crops. In the United States, the Sri Lankan weevil was first identified on Citrus sp. in Pompano Beach a city in Broward County Florida. Three specimens were identified by Dr. Charles W. O’Brien, first as Myllocerus undecimpustulatus, a species native to southern India, and then again as Myllocerus undatus Marshall native to Sri Lanka, finally as Myllocerus undecimpustulatus undatus Marshall to show its status as a subspecies.

Rugose spiraling whitefly Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae)
A new addition on the list of whitefly species found in Florida, Aleurodicus rugioperculatus Martin, was originally called the gumbo limbo spiraling whitefly, but is now named the rugose spiraling whitefly. Being a fairly new species to science – identified less than a decade ago, not much information is available about this pest. It is an introduced pest, endemic to Central America, and was reported for the first time in Florida from Miami-Dade County in 2009. Since then it has become an escalating problem for homeowners, landscapers, businesses, and governmental officials throughout the southern coastal counties of Florida. Feeding by this pest not only causes stress to its host plant, but the excessive production of wax and honeydew creates an enormous nuisance in infested areas. The presence of honeydew results in the growth of fungi called sooty mold, which then turns everything in the vicinity covered with honeydew black with mold.

The UF/IFAS Assessment of Nonnative Plants in Florida’s Natural Areas: History, Purpose, and Use
Nonnative invasive plant species pose a significant threat to Florida’s natural areas. The UF/IFAS Assessment of Nonnative Plants in Florida’s Natural Areas (hereafter, UF/IFAS Assessment) uses literature-based risk assessment tools to predict the invasion risk of both nonnative species that occur in the state as well as species proposed for introduction. The UF/IFAS Assessment team has evaluated more than 770 species, including 97 species proposed for introduction or new uses. The team is actively identifying and evaluating potentially problematic nonnative species (and sub-specific or hybrid taxa). Recommendations and supporting information from the UF/IFAS Assessment can be found at http://plants.ifas.ufl.edu/assessment. This 6-page fact sheet was written by Deah Lieurance, S. Luke Flory, Aimee L. Cooper, Doria R. Gordon, Alison M. Fox, Joan Dusky, and Linda Tyson, and published by the UF Department of Agronomy, November 2013.

Public Land Management Agencies’ and Nonindustrial Private Forest Landowners’ Perceptions towards Ecosystem Services
The state of Florida has more than 16 million acres of forestland. From clean air to pulp for paper to aesthetic landscapes, humans benefit from private and public forests in many different ways. However, small private landowners and public land management agencies manage the majority of this land, and it is up to these people to decide how society will benefit from those forests. This paper uses the concept of ecosystem services to explore the reasons why public land management agencies and private landowners manage their forests.

Eastern Bloodsucking Conenose, Triatoma sanguisuga (LeConte) (Hemiptera: Reduviidae: Triatominae)
The eastern bloodsucking conenose belongs to the subfamily Triatominae, known as the kissing bugs. Despite their affectionate vernacular name, they are particularly threatening “assassin bugs” who require blood meals to survive and reproduce. They are a known vector of American trypanosomiasis (or Chagas Disease) in South America, a debilitating illness caused by the parasite Trypanosoma cruzi. This disease is a problem in South and Central America and has been detected in the United States, but has not been found in Florida. This 4-page fact sheet was written by John L. Capinera, and published by the UF Department of Entomology and Nematology, November 2013.

Why is your cup of coffee so expensive? Because of a tiny bark beetle!
Sometimes an insect pest attacking crops in places as far away as Indonesia or Ethiopia can be very important to us here in Florida. One such insect is the coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scolytinae), a tiny (1.5 mm) bark beetle that originated in the highlands of central Africa. It would probably remain one of the many inconspicuous little beetles in the tropics, if not for the choice of its host: seeds of several Coffea species.

Using Reclaimed Water to Irrigate Turfgrass: Lessons Learned from Research with Phosphorus
Municipal wastes are treated at a wastewater treatment facility to produce biosolids and reclaimed water. Reclaimed water treated by filtration and chlorination is safe to use for designated purposes, such as residential landscape irrigation. Florida began using reclaimed water in 1966, and it is a leading state for using reclaimed water. Approximately 660 million gallons of reclaimed water are used every day in Florida, and the state encourages using reclaimed water as an alternative water source to reduce the pressure on potable water supplies. This 3-page fact sheet summarizes the results of a recent research project and provides research-based information for improving nutrient and water management with reclaimed water irrigation of turfgrass.

Identification and Control of Coral Ardisia (Ardisia crenata): A Potentially Poisonous Plant.
Coral ardisia, also known as coral berry, spice berry, and scratchthroat, was introduced to Florida in the early 1900’s for ornamental purposes. Since then, it has escaped cultivation, and it is found in hardwood hammocks and other moist, natural-wooded areas and grazing lands. Although there is no published literature supporting the theory that coral ardisia is toxic, it is suspected that the berries and/or foliage are poisonous to livestock, pets, and humans.

The Use of Cost-Benefit Analysis in Environmental Policy
When analyzing environmental problems, economists consider both the benefits and costs of actions. If benefits exceed costs then economic theory supports that action. For example, if the total benefits of conserving land exceed the costs then cost-benefit analysis would support conservation of the land. However, great care must be taken to accurately identify and quantify benefits and costs to determine whether an action is cost-benefit justified. Stakeholders may have an incentive to overstate costs or benefits, in order to influence decision-making. This 5-page fact sheet was written by Elizabeth F. Pienaar, and published by the UF Department of Wildlife Ecology and Conservation, September 2013.

Spanish Moss, Ball Moss, and Lichens – Harmless Epiphytes
Epiphytes are “air” plants that survive on moisture and nutrients in the atmosphere. Several epiphytic plants, like Spanish moss, ball moss, and lichen, are common to the Florida landscape and southeast United States. People unfamiliar with epiphytes sometimes worry that they may cause injuries to the plants they perch in. Epiphytes do attach themselves to plants, but they do not harm the plants, unlike mistletoe, a plant parasite. Without soil as a source of nutrients, epiphytic plants have evolved the capacity to obtain minerals dissolved in water that flows across leaves and down branches.

Green orchid bee Euglossa dilemma Friese (Insecta: Hymenoptera: Apidae)
Green orchid bees are a quite conspicuous and charismatic species. This is mostly due to their large size and bright metallic-green coloration. They are very fast and agile flyers, and can be seen quickly darting from flower to flower separated by long periods of hovering. Male orchid bees collect fragrant volatile compounds from their environment and present them to females by fanning their wings and “spray ventilating” their bouquet for the inspection of prospective mates. In Florida, male green orchid bees are attracted to chemicals produced by certain wood-rot fungi, decomposing vegetation, perfume flowers, and certain essential oils such as clove and cinnamon oil. Male green orchid bees can be quickly and easily attracted and observed by soaking a small piece of paper with clove oil and placing it outside. This 4-page fact sheet was written by Aaron Mullins, and published by the UF Department of Entomology and Nematology, October 2013.
