As part of an integrated pest management system, the L2L CISMA utilizes the most up-to-date research and best management practices in all aspects of invasive species management. 

Why are non-native invasive species (NNIS) a problem?

1. They are introduced where they did not evolve, thus they have no natural enemies to limit their numbers
2. Their rapid growth rate and reproductive rates allow them to quickly invade new habitats
3. They out-compete native species, especially when an ecosystem is stressed
4. NNIS span landscapes, ownerships, and jurisdictions
5. Some are toxic, like spotted knapweed, poison hemlock, and wild parsnip to name a few

Threats of NNIS include replacing native ecosystems, reducing biodiversity, changing ecological processes, degrading recreational opportunities, and compromising wildlife and livestock grazing habitat.
