This section highlights both wild and man-made habitat for pollinators. Pollinator habitat includes the food and nesting resources required to support wild communities. The major group of insect pollinators, bees, consist mostly of soil and cavity nesting species; the young are reared on mass-provisioned pollen in brood chambers located in the soil or other substrate such as plant stems. In addition to vegetation enhancements that increase the quantity and/or quality of larval or adult resources, farmers and other land managers have opportunities to preserve wild land and uncultivated or undisturbed areas of soil to promote pollinators.
