ALT You are cordially invited to be a GLANSIS Reviewer Who: Professional level experts in the field are invited to participate in a review process for the Great Lakes Aquatic Nonindigenous Species Information System. What: The GLANSIS database provides information on exclusively aquatic nonindigenous species in the entire Laurentian Great Lakes region regardless of national or state-level boundaries. GLANSIS does not provide data on reptiles, amphibians, or waterfowl, since they spend substantial portions of their lives outside the water. The database also includes facultative wetland plants in its target species. GLANSIS formally requests your participation in an external review process that will assist in the publishing of risk and impact assessments as well as species profiles that appear in the GLANSIS database. Each assessment and profile document follows a rigorous review process requiring two external reviews by subject matter experts before being published on the GLANSIS website.
