Artificial reefs are constructed to provide several important ecosystem services to coastal communities and fisheries around the world, and their deployment results in significant socio-ecological and economic effects. To understand these effects, this document gives an overview of the agencies and people involved in the use of artificial reefs, how the implementation of these reefs influences their perception, and what issues are associated with their deployment. This document also specifically describes the process by which most artificial reefs are implemented in Florida.

The Punky Wood Ambrosia Beetle and Fungus in Florida that Cause Wood Rot: Ambrosiodmus minor and Flavodon subulatus
Ambrosiodmus minor is an invasive ambrosia beetle in the southeastern United States, including Florida. It is considered of low importance because evident economic or ecological impacts have not been observed. However, it is associated with a unique ambrosia fungus, Flavodon subulatus, which causes rapid wood rot. Wood decay caused by this association between Ambrosiodmus and Flavodon is increasing in dead trees across the introduced range, especially in Florida. This 4-page fact sheet written by Demian F. Gomez and Jiri Hulcr and published by the UF/IFAS School of Forest Resources and Conservation offers guidance in identification of the pest, the symptoms of an infestation, and explanation of the insect’s biology. In addition, we provide an updated overview of contemporary management and monitoring of the species.

Creating Wildflower Habitats in Golf Course Out-of-Play Areas
Habitat loss from urbanization and agricultural intensification is reducing native bee and monarch butterfly populations, but golf courses in urban areas present an opportunity to mitigate the negative effects of urbanization on pollinators and the environment. It is feasible to enhance a golf course’s ability to support more species and a greater abundance of wildlife by planting the 40% to 70% of acreage not used for the game of golf in wildflowers. With the most golf courses of any US state, Florida is poised to set the stage for golf course environmental stewardship. This 8-page fact sheet written by Rebecca Nestle, Grace Cope, Nicole Benda, and Adam G. Dale and published by the UF/IFAS Entomology and Nematology Department is intended to provide guidelines for Florida golf course superintendents to aid in their efforts to conserve important wildlife while reducing maintenance inputs and associated costs.

Oyster-Predator Dynamics and Climate Change
Oysters are one of the most important natural resources found in coastal and estuarine areas of Florida, but some Florida oyster populations appear to be declining. One possible driver of oyster population decline is increased mortality from oyster predators, including marine snails. But other environmental factors, such as changes in temperature or salinity, may also affect oysters. This 5-page fact sheet written by Gabrielle Love, Shirley Baker, and Edward V. Camp and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences describes how a changing climate may affect oysters directly but also indirectly by affecting their predators.

Spatial Measurements on USGS Topo Maps
United States Geological Survey topographic maps provide a variety of geospatial measurement tools thanks to their built-in georeferencing capabilities. Georeferencing facilitates display of geographic coordinates and measurement of distances, perimeters, and areas on PDFs using the measure tools built into Adobe Reader and Adobe Acrobat. This 7-page fact sheet written by Hartwig H. Hochmair and published by the UF/IFAS School of Forest Resources and Conservation explains and showcases the use of these geospatial readout functions. It also provides background information about and assistance with estimating point coordinates on the Universal Transverse Mercator grid cast on USGS topographic maps as an optional layer.

An Introduction to USGS Topo Maps
Topographic maps provide both a detailed and accurate representation of cultural and natural features on the ground and a quantitative representation of relief, usually using contour lines. They can be used to address spatial questions in disciplines related to natural resources, hydrology, forestry, agriculture, or ecology. In 1879, the United States Geological Survey began to map the topography of the United States, producing new map versions of each area at semi-regular time intervals. US Topo maps are the current generation of USGS topographic maps. Unlike traditional topographic maps, the US Topo product is automatically generated from national map databases with topographic maps and produced every three years for all 48 of the contiguous United States, Hawaii, and the United States territories. They are published as freely available geospatial PDF documents that facilitate coordinate readings and spatial measurements (e.g. distance, area) through built-in georeferencing technology. This 7-page fact sheet written by Hartwig H. Hochmair and Adam R. Benjamin and published by the UF/IFAS School of Forest Resources and Conservation focuses on US Topo quadrangle download procedures and layer structure.

Living Shoreline Monitoring: How do I evaluate the environmental benefits of my living shoreline?
Living shorelines are structures made of natural materials such as oyster shell, sand, mangroves, salt marsh plants, and other organic materials built to protect properties from erosion. In addition to increasing shoreline stability, living shorelines enhance many valuable ecosystem functions. In this new 11-page publication of the UF/IFAS Department of Soil and Water Sciences, we provide homeowners, land managers, and Extension agents materials lists, protocols, and data sheets for measuring change in ecosystem function. Measuring and interpreting these measurements will help evaluate living shorelines projects as well as provide the foundation for monetarizing the value of these structures. Written by Laura K. Reynolds, Natalie C. Stephens, Savanna C. Barry, and Ashley R. Smyth.

Stormwater Pond Management: What You Need to Know about Aeration
This new 6-page document is intended to provide Floridians and their communities with information on a specific management practice in stormwater ponds: the use of fountains and other aeration approaches. These practices may provide opportunities both to improve water quality within the pond and protect downstream water quality. Specifically, this document gives basic information on fountains and the pros and cons of fountain installation and use. In addition, we provide information for pond managers or community decision makers on how to best manage ponds for effective pollutant removal in the pond and downstream water quality protection. Written by Samantha T. Howley, Steven P. Hohman, and Alexander J. Reisinger, and published by the UF/IFAS Department of Soil and Water Sciences.

Soil Health Response of Histosols to Flooded versus Dry-Fallow Conditions during Summer
Evaluating changes in soil properties associated with flooded fields during the summer months in the Everglades Agricultural Area (EAA) provides us an opportunity to assess the effect of soil management associated with flooded versus dry-fallow field conditions on Histosols. This information will be beneficial to current and potential growers farming flooded rice in south Florida, as well as Extension agents who work on rice and soil conservation agencies such as the USDA Natural Resources Conservation Service (NRCS). This new 6-page publication was written by Jehangir H. Bhadha, Jay Capasso, Abul Rabbany, Nan Xu, and Matthew VanWeelden, and published by the UF/IFAS Department of Soil and Water Sciences.

Lightning Damage to Landscape Palms
Florida is considered by some to be the lightning capital of the world. Florida has on average 3,500 cloud-to-ground lightning strikes per day and 1.2 million strikes per year. Given so many strikes, the probability of damage to certain palms is significant. Coconut palms, royal palms, and Washington palms are particularly vulnerable due to their great heights, but other tall palms may be equally susceptible. This new 6-page publication of the UF/IFAS Environmental Horticulture Department describes and includes many helpful photos of symptoms of lightning damage as well as lightning protection systems. Written by Stephen H. Brown, Douglas Caldwell, and Ralph Mitchell.
