State wildlife officials first discovered New Zealand mudsnails in South Boulder Creek in 2004 and are taking action to prevent them from spreading. The New Zealand mudsnail competes with native invertebrate species and can destroy forage important to trout and other native fishes. Learn more how to identify the New Zealand Mudsnails, how to stop the spread and how to report sightings.

The Colorado Division of Wildlife is monitoring the state's waters for the introduction of an aggressive invasive species, the rusty crayfish. Rusty crayfish were found for the first time in Colorado during routine sampling operations in 2009 in the Yampa River drainage between Steamboat Springs and the town of Yampa. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Learn more how to identify the rusty crayfish, how to stop the spread and how to report sightings.

Emerald ash borer (Agrilus planipennis) is an exotic, invasive, wood-boring insect that infests and kills native North American ash trees, both in forests and landscape plantings. With EAB now in several areas of the Show-Me State - and its ability to hitchhike on firewood - the probability of it spreading to noninfected areas in the state is high.

Although not yet detected here, thousand cankers disease (TCD) is a potentially fatal disease of black walnut, caused by the walnut twig beetle (Pityophthorus juglandis) and an associated fungus (Geosmithia morbida). TCD could easily spread to Missouri from the several eastern and western states where TCD is already present. You can help minimize the chances of spreading TCD by following these steps:
