A worm is a worm is a worm, right? Except that there are more than 7,000 species of worms, and the longer you look, the more complex their world becomes. Earthworms compete. Earthworms invade. Earthworms… jump?
Provides information for invasive species as food, including species on land and sea. Provides recipes and frequently asked questions about eating invaders.
Harvesting and eating invasive plants may add a new dimension to “local foods.” Many invasive plants and animals started out as old world food that escaped from colonial gardens.
An Ecological Risk Screening Summary, or Risk Summary, provides a rapid evaluation of a species’ potential invasiveness. These evaluations give us, as well as our natural resource stakeholders and the public, a quick way to determine which species are most likely (high risk) and least likely (low risk) to cause damage if they spread outside of their natural range, and which ones have insufficient information to make such a determination (uncertain risk).

Managers often struggle to calculate the ecological and economic costs associated with invasive species. Yet, knowing these impacts can boost support and understanding for invasive species management. In a new book chapter, NWRC economist Dr. Stephanie Shwiff and colleagues describe how economists determine costs of both primary and secondary impacts from invasive species and how these translate into jobs and revenue in regional economies.
