It was pouring rain today on my a.m. walk and there trying to crawl across the wet road was a native Pacific Banana slug stretched out long during its movement towards the friendly green stuff on the edge of the road. Our Northwest wet and gray climate is a slugs haven with all the plant life and other nutrients they can consume.
The Banana slugs mostly inhabits the forest floor ingesting only the seedlings of the non native plants and trees so we try not to destroy it. It carries with it fungi and other nutrients that get spread into the soil as the slug moves along. Whereas, the European species is a non native slug that is a pest to our vegetable gardens and a whole army will ingest several plants during one night. A gardener can enter their garden in the a.m. and find a whole row of vegetables gone! It is work to keep the garden safe from this species but we mostly win.
