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?

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).

Invasive species can have severe impacts on ecosystems, economies, and human health. Though the economic impacts of invasions provide important foundations for management and policy, up-to-date syntheses of these impacts are lacking. To produce the most comprehensive estimate of invasive species costs within North America (including the Greater Antilles) to date, we synthesized economic impact data from the recently published InvaCost database (see related research article: InvaCost, a public database of the economic costs of biological invasions worldwide (Sep 8, 2020).

To date no studies have been undertaken on the costs and benefits of IAS management in the Caribbean. This may partly explain why there has been negligible funding to combat the onslaught of these exotic species in the region. As a result it was decided to provide individuals involved in the UNEP-GEF Project, "Mitigating the Threats of Invasive Alien Species in the Insular Caribbean" with training and an opportunity to undertake Cost-Benefit Analyses (CBAs) on some selected IAS. The CBAs undertaken and reported in this publication clearly demonstrates that the benefits of managing IAS outweigh the costs.

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.
