National Invasive Species Awareness week is next week, and Beltrami County Aquatic Invasive Species Lakes Technician Bruce Anspach wrote a letter explaining invasive species.
An invasive specie can be both terrestrial or aquatic, and are considered invasive when they cause harm to the environment, economy or human health.
A pheasant is a nonnative specie, for example, but are not considered invasive because they benefit the economy.
While animals may move invasive species around, people can move invasive species across the county, state, country and even the world.
Many of our invasive species today come from Europe and Asia, and several aquatic varieties are believed to have come into the Great Lakes region by ship ballasts.
