To win the "Theodore Roosevelt Genius Prize Competition for Management of Invasive Species," participants must submit their technology innovation solution -- such as tools, equipment, methods, strategies, etc., that help land managers directly reduce the spread and impacts of invasive species within the United States and its Territories. Solutions should focus on invasive species that cause harm to native ecosystems. Solutions may be species-specific, but universal control techniques that may have multiple species benefits are preferred. Submission period: Open until April 30, 2022, 11:59 EDT.

The public now can help reimagine what drives wildlife conservation in the 21st century by participating in the U.S. Fish and Wildlife Service’s Theodore Roosevelt Genius Prize Competitions. The competitions will engage the public to help address six important issues: preventing wildlife poaching and trafficking, promoting wildlife conservation, managing invasive species, protecting endangered species, managing nonlethal human-wildlife conflict, and reducing human-predator conflict.

The Texas Parks and Wildlife Department is proposing changes to regulations regarding harmful or potentially harmful fish, shellfish and aquatic plants. The proposed changes significantly reorganize the existing rules to enhance accessibility, meet the changing needs of the regulated community, and address current and potential future threats posed by these exotic species. The proposed rules will be published in the Texas Register no later than Friday, Oct. 2. At that time, comments on the changes can be provided on the TPWD public comment page until Monday, Nov. 9. The TPW Commission will take public comment on the proposed changes at their meeting on Tuesday, Nov. 10 in Austin. Comments on the proposed changes also can be submitted to Ken Kurzawski at (512) 389-4591, email: ken.kurzawski@tpwd.texas.gov.

National park philanthropy doesn't stop when it comes to trail and campground maintenance, science and research, or bringing inner-city youth to a park. Each year nearly $1.5 million from the National Park Foundation goes towards battling invasive species across the system.

ARS scientists in Nevada, studied ways to control cheatgrass and restore rangelands to a healthy mix of plants, which in turn reduces wildfire threats, supports wildlife, and increases sustainable grazing resources.

The Chesapeake Bay Database project ended in 2020. This site will remain available for historical reference, but the database has not been updated since 2020 and will not receive any further updates. See more information in the project overview. For up to date information on introduced marine and estuarine invertebrates and algae in Chesapeake Bay, please visit the NEMESIS North American database.

In 2003, the U.S. Fish and Wildlife Service released the publication, Native Plants for Wildlife Habitat and Conservation Landscaping: Chesapeake Bay Watershed. Citizens, schools, non profit organizations, communities and government agencies used this resource to find the native plants that met their local conditions and interests in order to create landscapes to attract wildlife and reduce the amount of pollutants going into the Chesapeake Bay.

To reach more citizens and organizations, the Alliance for the Chesapeake Bay and U.S. Fish and Wildlife Service envisioned an online version of the guide, the Native Plants Center Chesapeake Region. This expanded online guide includes a geo-locator feature to identify plants suited to your location, a searchable database of the native plants that meet your conditions, and (coming soon) an online network to interact with other Chesapeake Bay stewards.

A study conducted by Maryland Department of Natural Resources Biologist Dr. Joseph Love illuminates one of the biological factors that could be contributing to Chesapeake Channa’s efficient spread through Maryland’s waters. The study, published in the July 2024 edition of Northeastern Naturalist, found that the majority of female Chesapeake Channa, also known as northern snakehead, collected from the upper Chesapeake Bay carried eggs in two distinct sizes, suggesting those fish could spawn twice a year.

Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

Chinese tallow tree (Triadica sebifera) is a nonnative, invasive tree whose decaying leaf litter alters water quality and the microbial community in the wetland habitats. This negatively impacts the lifecycle of semi-aquatic species like frogs.
