Invasive threats in, near Lake Champlain

The above map was taken from this blog post from the Lake Champlain Basin Program, which sources it to U. Vermont and Sea Grant researchers. The caption says it all: There are 48 invasive species identified in lake Champlain, and at least another 136 - 136 of them!!! -  in waterways that connect to the lake, the Great Lakes, St. Lawrence Seaway and Hudson River.

I don’t know what else to say except holy cow.
