Why Care?

Invasive species affect our lives in many ways. In the United States, environmental damages and losses due to invasive species are estimated to cost more than $138 billion annually.  Major economic losses have occurred in agriculture, forestry, and several other segments of the U.S. economy, in addition to harming the natural environment.  Invasive shrubs such as buckthorn and honeysuckle prevent the regeneration of young trees, causing a long-term but very serious impact on forestry in Wisconsin a $20 billion per year industry in our state.  Control of buckthorn alone has been estimated to cost $500-2,000 per acre over multiple years.  If we consider the environmental impacts of invasive species, the net result is a loss of diversity of our native plants and animals.  Invasive species now rank just behind habitat loss as the leading cause of rare species declines and approximately 42% of threatened and endangered species are at risk primarily because of invaders.  Depending on your relationship to the natural world you may see different and compounding effects.  Many of the costs related with invasive species are passed down to local governments and homeowners.  For more information on how invasive species impact our daily lives and what you can do to prevent their spread, see below:
