National Invasive Species Awareness Week Kicks-Off on Monday

The National Invasive Species Awareness Week (March 3-8, 2013) kicks off across the county with events highlighting efforts to prevent or slow the spread of invasive species. InvasiveNISAW-logo09 weeds and pests are more than a gardener’s dilemma. These species are not native to our area and pose a threat to natural areas, human health, and our local economy.

The estimated economic impact of invasive species totals 143 billion dollars per year within the United States. Within the state of Oregon, the impact associated with just twenty-one invasive weed species costs Oregonians $125 million dollars per year in lost agricultural production, fire damage, and control expenses. We all pay the bill through increased food costs, higher taxes, and decreased property values. These impacts clearly show the economic benefits associated with controlling invasive weeds

Oregon’s beautiful landscape is also threatened by invasive species that invade our forests and natural areas, replacing native beauty with a weedy and degraded landscape. Fish and wildlife suffer with lost habitat. No one wins with invasive species.
