If you are unable to keep the fish, the TWRA asks you to submit photos of the fish and send the image to us. You can contact the nearest TWRA office by phone here, or by email at ans.twra@tn.gov.

The Arkansas Department of Agriculture is notifying the public that a new invasive grass species, Cogongrass, has been confirmed in Arkansas for the first time. For several years botanists and land managers have been on the lookout for Cogongrass (Imperata cylindrica) in southern Arkansas. This aggressive species, native to Southeast Asia, has spread rapidly across the Deep South over the past few decades. Cogongrass is considered one of the worst invasive species in the world, causing both economic and ecological damages that impact forestry, agriculture, rangeland, and natural ecosystems.

Any sightings of Cogongrass in Arkansas should be reported to Paul Shell, the Department's Plant Inspection and Quarantine Program Manager, at paul.shell@agriculture.arkansas.gov or 501-225-1598.

Divers monitoring Lake Tahoe have discovered invasive New Zealand mudsnails in areas off the South Shore, the Tahoe Regional Planning Agency (TRPA) and Tahoe Resource Conservation District (Tahoe RCD) announced today. This is the first time the species has been detected in the Tahoe Basin.

Following rapid response protocols under the federally approved Lake Tahoe Aquatic Invasive Species Management Plan, TRPA convened an incident team comprised of staff from TRPA and Tahoe RCD and partner experts. The team is rapidly deploying scientists, beginning with lake-wide dive surveys to determine the extent of the infestation and sharing all available information with state and federal wildlife managers through the Lake Tahoe Aquatic Invasive Species Coordinating Committee. Get up-to-date information on the response and potential protocols for management of the infestation on the TRPA New Zealand mudsnail page.

The Washington State Department of Agriculture (WSDA) is beginning its annual search for pests that could threaten the state’s environment and agricultural industry. Staff will set thousands of traps statewide to monitor for the introduction or spread of more than 130 invasive pests and diseases, including spongy moth, Japanese beetle, apple maggot and northern giant hornet.

WSDA is still asking residents to report all suspected hornet sightings. Northern giant hornet queens should be active now and could be spotted while they establish their nests. As the colony grows, worker hornets may become increasingly visible throughout the summer and into the fall. See Public hornet trapping instructions for more information.
