New publication: Enhancing Urban Suburban Landscapes to protect Pollinators. “The way we garden and manage the landscapes of the Northwest can promote the health of bees, butterflies, and other insects.  Homeowners, gardeners, landscape professionals and volunteer groups all can work to attract a wide range of pollinators to their properties.  This guide offers detailed plant lists, garden designs and advice on creating pollinator habitat.  Once plants are in the ground, learn to keep them healthy without exposing pollinating insects to pesticides that are toxic to them.” (Andony Melathopoulos, et all, OSU- EM 9289)
