  • Innovation in Climate Adaptation: Harnessing Innovation for Effective Biodiversity and Ecosystem Adaptation

    • Jan 17, 2024
    • National Wildlife Federation.

    • Climate change poses growing risks to species, ecosystems, and people, and is challenging many of the assumptions that underpin modern conservation practice. As a result, there is an urgent need to not only center climate adaptation in conservation policy and practice, but for adaptation responses to be bolder and more innovative. Innovation in Climate Adaptation is designed to address this need by promoting creativity and innovation in the practice of climate adaptation for biodiversity and ecosystem conservation. This guide is a collaboration among the National Wildlife Federation, the U.S. Geological Survey Climate Adaptation Science Center Network, and the IUCN Species Survival Commission Climate Change Specialist Group.

  • A Decision Support Framework for Conservation Introductions

    • Jan 2024
    • DOI. FWS. Pacific Region; Zenodo.

    • The purpose of this nonregulatory decision support framework for conservation introductions is to foster transparent, inclusive, and defensible decision-making by the U.S. Fish and Wildlife Service (USFWS) when considering conservation introduction as a strategy. This framework was developed by and for the USFWS in the Pacific Region based on input from a wide range of federal, state, territorial, Tribal, Indigenous, and non-governmental representatives in the Pacific Islands and Pacific Northwest. Risk assessment is a central component of the framework, where uncertainty in predicted outcomes of the proposed management strategies is explicitly considered.

  • The Silent Invasion: Nonnative Trees Threaten American Forests

    • Jan 23, 2024
    • USDA. FS. Southern Research Station. CompassLive.

    • Nonnative tree species are gaining a foothold in forest ecosystems. These trees compete with native species for resources, sunlight, and space. Tree of heaven and Chinese tallow tree are the most invasive tree species in the South, according to a recent study which uses Forest Inventory & Analysis data to create an indicator of nonnative tree regeneration success and can help prioritize the species and locations for treatment.

  • Spotted Lanternfly Reveals a Potential Weakness

    • Jan 19, 2024
    • USDA. Blog.

    • USDA scientists have discovered that the spotted lanternfly, an invasive threat to fruit crops and many trees, may have an Achilles heel – an attraction to vibration. A native of China, the insect was discovered in Pennsylvania in 2014 and has since spread to 13 other states. Though beautiful as an adult, the insect is a voracious eater that feeds on woody and ornamental trees as well as a wide variety of crops and plants. Left unchecked, Pennsylvania alone could lose hundreds of millions of dollars and thousands of jobs.

      Richard Mankin, an entomologist with the USDA Agricultural Research Service’s Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, FL, and colleagues found a new way to potentially corral and control the pests. Their research was published in the Journal of Economic Entomology.

  • Regional Invasive Species & Climate Change Management Challenge: Out of Control? The Effects of Climate Change on Biological Control Agents and their Target Hosts

    • 2023
    • University of Massachusetts Amherst.

    • Biocontrol is an important management tool that utilizes one species (a biocontrol agent) to control another (a target host) and can be an effective approach for controlling populations of invasive species across broad spatial scales. There are growing concerns that mismatches between how biocontrol agents and their hosts respond to climate change could alter the efficacy of current and future biocontrol programs.

  • Southeast (SE) Bat Hub

    • North American Bat Monitoring Program.

    • The Southeast (SE) Bat Hub was created in summer 2022 to coordinate North American Bat Monitoring Program (NABAT) survey projects in the Southeastern states. The Hub provides services, updates, and content to assist the NABat efforts across the region.

      Since 2006, white-nose syndrome (a fungal disease) has been infecting bat populations across the U.S. This disease has killed some species of bats, such as the tricolored bat and northern long-eared bats at alarming rates.

  • Invasive Blue Land Crabs Reported Along South Atlantic Coast: Coastal Georgia Residents Encouraged to Be Watchful

    • Dec 20, 2023
    • Georgia Department of Natural Resources.

    • Recent sightings of a large, non-native land crab along the South Atlantic coast, including in coastal Georgia, are a cause for concern, according to the Georgia Department of Natural Resources’ Wildlife Resources Division (WRD). Blue land crabs are native from Brazil to south Florida and can be as large as 5-6 inches. Sightings recently have been reported well north of the crabs’ native range, including the coasts of Georgia, South Carolina and North Carolina. Multiple reports have been made to Georgia WRD offices.

      The public is encouraged to take photos and report sightings of blue land crabs at Questions about blue land crabs? Contact a local Georgia WRD office (details at

  • Management Plan for the European Green Crab (Draft)

    • Jun 21, 2023
    • Aquatic Nuisance Species Task Force.

    • The National European Green Crab (EGC) Management and Control Plan was developed by a multi-agency European Green Crab Working Group for implementation by the Aquatic Nuisance Species Task Force following final approval.

      The purpose of the 2023 EGC plan is to provide guidance for efforts to prevent future introductions, to rapidly detect and respond to new invasions of EGC before they become established and create ecological and economic damage, and to manage current populations that pose an undue threat to resources of importance for ecosystems and local cultures. The 2023 EGC plan proposes to update the 2002 plan by providing a more focused set of approaches for future management, based on significant changes in the distribution of EGC, new technologies available for identifying sources and mechanisms of spread, better information regarding the tradeoffs for different management efforts, and new methods for data management and sharing. The 2023 EGC plan also describes current strategies for coordinating the activities of scientists, resource agencies, Tribal and First Nation organizations, and other entities.

      Public Comment Period -- Written comments must be submitted on or before February 9, 2024. For more information, see the Federal Register notice Draft Revised National European Green Crab Management and Control Plan (Dec 26, 2023)
