A century ago, coastal dunes threatened to overwhelm the city of Florence, Oregon. The sand swallowed roads, highways, and houses. When “Dune” author Frank Herbert visited the area in 1957, he was stunned by the awesome power of the sand. Eventually, it inspired his fictional desert planet, Arrakis.But now, the dunes that inspired “Dune” are disappearing. To solve the sand problem, the US Forest Service planted dunes with non-native beachgrass, hoping its strong roots would keep the dunes in place. The strategy worked… too well. The grass spread, out-competing native species and transforming the dunes. At one popular spot, roughly 60% of what was once open sand is now gone.Producer Justine Paradis traveled to the Oregon Coast to see the mountains of sand which inspired a sci-fi classic, and meet the people working to save them.Featuring Dina Pavlis, Patty Whereat Phillips, and Jesse Beers. SUPPORTOutside/In is made possible with listener support.
