invasive plants

Most people wouldn’t associate sand dunes with a forest, but on the central Oregon Coast, the Siuslaw National Forest is home for the Oregon Dunes National Recreation Area – 40 miles of wind-sculpted, shifting sands towering up to 500 feet above sea level.

Formed by the ancient forces of wind, water and time, these dunes are like no others in the world. This is the largest expanse of coastal sand dunes in North America and they provide numerous recreational opportunities with thick “tree islands,” open dunes, marsh-like deflation plains and beaches.

As spring awakens across the country, outdoor recreation enthusiasts are beginning to look again for opportunities to enjoy the great outdoors. America’s spectacular national forests and national grasslands provide some of the greatest opportunities for outdoor recreation in the world.

But these beautiful and inspiring natural places are also under attack from hundreds of invasive plants, animals and pathogens. These exotic invaders disrupt natural ecological balance and can negatively impact the quality of outdoor recreation experiences. Invasives can threaten human health and safety and possibly reduce access to some areas.
