Spanning more than 40 miles, the Oregon Dunes National Recreation Area is the longest expanse of coastal sand dunes in the United States.  The dunes stretch from Florence to Coos Bay and attract more than 1 million visitors each year.

Siuslaw National Forest botanist Armand Rebischke will be giving a presentation on invasive plants, Dunes ecology, and why you should care!  Join him at 4:00 PM on Thursday, May 2nd, at the Siuslaw Library in Florence.
