Hidden in a sea of sand, there are plants, insects and animals that call the Oregon dunes home. But some species, such as the Siuslaw hairy-necked beetle, are seeing their habitat shrink year after year. Dina Palvis is a dune enthusiast and author of the book, “Secrets of the Oregon Dunes.” She joins us to share the ecology of the dunes and how invasive plant life is changing the landscape of Oregon’s coast.
