Boat owners are required to purchase the ANS Stamp and operators must retain proof of purchase (electronic or printed receipt) on his or her person, the motorboat or sailboat, when operating the vessel (C.R.S. 33-10.5-104.5). ​Funding contributes to prevention and management of ANS in the state.

Emerald Ash Borer (EAB) was found in Boulder, CO, in September 2013. As a non-native insect, EAB lacks predators to keep it in check. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). EAB is responsible for the death of millions of ash trees in the Midwest. Help protect Colorado's ash trees! Don't move firewood, and consider chemical treatments to protect high-value ash trees.

The South Dakota Department of Agriculture (SDDA) has confirmed that an infestation of emerald ash borer (EAB) has been discovered in northern Sioux Falls. This is the first confirmed infestation in South Dakota. Emerald ash borer is an invasive insect that has killed tens of millions of ash trees in at least 32 states. On May 9, 2018, Secretary Mike Jaspers implemented an Emergency Plant Pest Quarantine in order to prevent or reduce the spread of the EAB. This emergency quarantine is effective immediately. For more information, see the Emerald Ash Borer in South Dakota website.
