The invasive species curve shows that for every dollar spent on prevention, there is an economic multiplier of 100. This economic multiplier stems from cost savings due to the huge negative economic impact post invasion. These economic impacts can be seen in the form of water quality, infrastructure, loss of recreation, fisheries decline, etc. Watch the great video below from The Biosecurity Council of Western Australia to learn more.
The Canadian Council on Invasive Species conducted a survey to determine why boaters do not always clean, drain, and dry their boats. They, found that, “When asked what might prevent people from performing the “Clean” actions, people most often said lack of availability of equipment and a place to do it.” For more information on the survey and its results please go here.
What’s just now being discovered is that Zebra Mussels, one of the most tenacious aquatic invasive species, may have a compounding effect on farm pollution. Lake Mendota in Wisconsin, which first discovered mussels 2 years ago, has seen severe blue-green algae blooms this year that killed thousands of fish in Lake Mendota and the Yahara River. Stephen Carpenter, the director of the limnology center at UW Madison, said he was “shocked to see the bright green hue stretching as far as he could see” across the lake. Other scientists reported seeing fish gasping for breath on the surface or invertebrates crawling out of the water and dying.Read More
