Pollinators are critically important for food production and healthy ecosystems. Pollinator populations such as wild and domesticated bees, monarch butterflies, and many other butterfly species are in decline nationally. Enhancing, restoring, and maintaining linear roadside habitat for pollinators can provide connections for pollinators to disperse between agriculture fields and other natural habitat areas. Pollinator Habitat Ranks identifies high value areas for creating, preserving, or enhancing pollinator habitat on WSDOT owned lands along the state highway system. Three separate models were developed that ranked state routes for monarch habitat, pollinator habitat, and urban gateway pollinator habitat for every half mile highway segment. Monarch ranks were based on the proximity of highway segments to suitable monarch and milkweed habitat as identified by the U.S. Fish and Wildlife Service’s habitat suitability index model. Pollinator ranks were based on the proximity of highway segments to pollinator dependent crops, protected public and private lands, wetland and riparian habitats, native and natural vegetation cover, oak/grassland habitat, and rare and imperiled animal pollinated plant species. Urban gateway ranks were applied to highway segments that intersected with urban areas and the proximity of the highway segment to protected public and private lands, wetland and riparian habitats, native and natural vegetation cover, oak/grassland habitat, and rare and imperiled animal pollinated plant species.
