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.

Bird’s Nest Fungi: Charismatic Mushrooms in Your Garden

The “bird’s nest” fungi (Nidulariaceae) are charismatic mushrooms that look like small nests containing multiple tiny eggs. Because the ecological role of bird’s nest fungi is to decompose wood, they are extremely common in disturbed areas with plant debris and mulch, such as trails and backyard gardens. These fungi tend to grow in large clusters, so it is common to see ten to a hundred of these “nests” at once. Bird’s nest fungi are not considered dangerous to plants, animals, or humans. This new 3-page publication of the UF/IFAS Plant Pathology Department was written by Nattapol Kraisitudomsook and Matthew E. Smith.

Species in the Laetiporus sulphureus species complex, also known as “chicken of the woods” mushrooms, are wood-decay fungi that cause brown rot within the heartwood of their tree hosts. The common name “chicken of the woods” is given to some species in this group because they are tasty edible mushrooms. Several Laetiporus species have been harvested to use as food colorants, to dye natural products such as wool, and for human consumption. This new 4-page publication of the UF/IFAS Plant Pathology Department, written by Brianna Benitez, Claudia A. Paez, Matthew E. Smith, and Jason A. Smith, describes these fungi as well as their ecology, management, and potential edibility.

A Beginner’s Guide to Water Management—Common Aquatic Birds Using Florida Lakes

Green-backed heron.

Florida LAKEWATCH is a citizen scientist program that monitors Florida's lakes. Since it was established in 1991, Florida LAKEWATCH has worked with thousands of volunteers to collect water quality data on more than 2,700 aquatic systems in Florida. It is the most comprehensive and longest-running water quality data source in the United States, if not the world. This 18-page circular written by Mark V. Hoyer and published by the UF/IFAS Program in Fisheries and Aquatic Sciences of the School of Forest Resources and Conservation describes Florida LAKEWATCH's volunteer aquatic bird-monitoring program. Citizen volunteers can provide a comprehensive and intimate understanding of birds and their interactions with Florida lake systems, helping to detect the changes in the types and numbers of birds using lakes that may indicate important natural or human-caused environmental trends. Whether you want to identify birds you’ve spotted or take an active role in the management and conservation of Florida's natural resources, this circular can help you learn the basics.

Urban tree diversity is important when attempting to create a healthy, beneficial, and resilient urban forest. Having a variety of trees can increase the aesthetic value for residents and create habitats for plants and animals. Some common street trees currently in the landscape are not site-appropriate and create infrastructure damage. By planting different types of trees in these locations, maintenance costs and infrastructure damage can be reduced and tree longevity increased. This new 4-page fact sheet is intended to provide urban foresters, arborists, landscape designers, and others in charge of tree planting with a process for introducing new species into the urban environment. Written by Deborah R. Hilbert, Andrew K. Koeser, and Robert J. Northrop, and published by the UF/IFAS Environmental Horticulture Department.

Two-leaf nightshade, Solanum diphyllum, is a member of the Solanaceae or potato family. It is native to Mexico southwards to Costa Rica. It has escaped cultivation in Florida and grows as far north as Duval County and from Volusia County south to Miami-Dade County. A “bird-dispersed” volunteer, it occurs in urban and conservation areas and on disturbed land. The plants produce abundant berries with many many small seeds. This new 5-page publication of the UF/IFAS Environmental Horticulture Department is primarily intended for Florida gardeners, landscapers, and land managers, and it contains information on identification, flowering, fruiting, and management recommendations for this widely occurring plant.
