Resources

Resources to aid in the planning, establishment, restoration, and maintenance of pollinator habitat.

The Xerces Society produces dozens of publications each year to share the latest science-based conservation information; guide conservation efforts; and support farmers, gardeners, and other invertebrate enthusiasts in creating healthy habitat for the "little things that run the world."

The pollinator resources found on this page support habitat restoration throughout the mainland United States and Canada.

Milkweeds (Asclepias spp.) are the required host plants for caterpillars of the monarch butterfly and thus play a critical role in the monarch’s life cycle. The loss of milkweed plants in the monarch’s spring and summer breeding areas across the United States is believed to be a significant factor contributing to the reduced number of monarchs recorded in overwintering sites in California and Mexico.
