The Asian Giant Hornet Public Dashboard shares detection and trapping data. Citizen scientists were able to view detections in real time, including the number of reported sightings and number of hornets confirmed by type. Coordinating this information provided input on future trapping and demonstrated the benefit of collaboration with citizen scientists. WSDA has indicated that citizen data sharing and bottle trapping efforts are crucial to protect Washington from this invasive species.

Natural Resources Stewardship staff (NRS) has determined that many non-native invasive plants (NNIs) known to present a significant threat to the quality and biodiversity of the natural areas occur in this 37,000-acre park system. To support the park mission to steward these lands, Montgomery County Department of Parks has prepared fact sheets for park managers and maintenance personnel with easy-to-read information about mechanical and chemical control methods for several terrestrial NNIs.

The goals of the California Invasive Species Action Week (CISAW) are to increase public awareness of invasive species issues and promote public participation in the fight against California's invasive species and their impacts on our natural resources.

Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.

Learn how invasive species are affecting California, with Invasive Species Week Lunchtime Talks (June 7-11, 2021). Webinars are part of California Invasive Species Action Week, organized by the California Department of Fish & Wildlife. Webinars were recorded and available for viewing.

Landowners, we need your help: CDFW has deployed nutria survey teams from the Delta through the San Joaquin Valley and needs written access permissions to enter or cross private properties for the purposes of conducting nutria surveys and, where detected, implementing trapping efforts. Landowners and tenants, we need your help (PDF | 598 KB); so CDFW can survey for and remove destructive nutria from your properties, complete and submit the Nutria Project Temporary Entry Permit (PDF | 207 KB).

This week, Florida Agriculture Commissioner Nikki Fried and the Florida Department of Agriculture and Consumer Services (FDACS) Division of Plant Industry (DPI), along with the U.S. Department of Agriculture (USDA), announced the eradication of the giant African land snail (GALS) from Broward and Miami-Dade counties. This eradication announcement marks only the second time this pest has been eradicated in the world, both in South Florida. For the past 11 years, the FDACS Division of Plant Industry has worked toward eradication through multiple rounds of visual surveys and inspections, K-9 detector dog surveys and inspections, manual collection and treatment programs. In total, 168,538 snails were collected from 32 core population areas comprised of thousands of properties.

The giant African land snail is a highly invasive agricultural pest, known to feed on over 500 varieties of plants. They also pose a risk to humans and animals by carrying rat lung worm, a parasite that can cause meningitis in humans. Giant African land snail is a federally regulated pest and both the USDA and DPI will continue to remain vigilant in their commitments to safeguard American agriculture through surveys, early detection, and rapid response. The public should continue to watch for the snails and report suspects to the FDACS-DPI hotline at 1-888-397-1517.
