OSU experiments show that vegetation doesn’t always prevent dune erosion

One of the best-known strategies to prevent dune erosion is to introduce plants whose roots will help hold sand in place and stabilize the dune. But experiments conducted at Oregon State University show that may not always be the case. Researchers found that newly planted vegetation can actually accelerate erosion in the face of extreme storms. Meagan Wengrove is an assistant professor of civil and construction engineering at OSU. She was involved in the experiments, and joins us to talk about what the findings could mean for coastal management.
