SALEM, Ore. (AP) — Scientists at Oregon State University have confirmed that two widespread, invasive beachgrasses are now genetically mixing, which could present additional challenges to communities and Pacific Northwest dune restoration. Oregon Public Broadcasting reports before the introduction of European and American beachgrass, there was far more open sand on the Oregon and Washington coasts. Where it as present, native vegetation promoted lower dunes that tended to shift and morph. It’s often better for communities and infrastructure if those dunes don’t move and instead provide a steady buffer. That’s why European beachgrass was brought in at the turn of the 20th century. It’s unknown how the hybrid will impact dune ecosystems and efforts underway to protect them from invading grasses.
