Managing Invasive Species: How Much Do We Spend?

Abstract

Invasive species: they’re along roadways and up mountain trails; they’re in lakes and along the coast; chances are they’re in your yard. You might not recognize them for what they are—plants or animals not native to Alaska, brought here accidentally or intentionally, crowding out local species. This problem is in the early stages here, compared with what has happened in other parts of the country. But a number of invasive species are already here, and scientists think more are on the way. These species can damage ecosystems and economies—so it’s important to understand their potential economic and other effects now, when it’s more feasible to remove or contain them. Here we summarize our analysis of what public and private groups spent to manage invasive species in Alaska from 2007 through 2011. This publication is a joint product of ISER and the Alaska SeaLife Center, and it provides the first look at economic effects of invasive species here. Our findings are based on a broad survey of agencies and organizations that deal with invasive species.1 The idea for the research came out of a working group formed to help minimize the effects of invasive species in Alaska.2 Several federal and state agencies and organizations funded the work (see back page).
