Researchers at South Slough Reserve Study Non-indigenous Estuarine Snails
A research team at the South Slough National Estuarine Research Reserve spent the summer of 2009 investigating and researching the distribution and density of a new invasive snail, Assiminea parasitologica. The new invader is rather small (4-6mm) and is native to Japan. A. parasitologica, commonly called AP, was first documented in North America in 2007; the snail was found in thousands per square meter in the upper reaches of the Coos Bay estuary. Scientists at the South Slough Reserve examined the Coos Estuary for this new invader and also recorded data on marsh environments and the distribution and density of three existing snails, both native and invasive, that share the same habitat as the new invader.
