Backyard Certified Habitat Program

Backyard Certified Habitat Program


Audubon Society of Portland, Columbia Land Trust and Friends of Tryon Creek have teamed up to create a unique Backyard Habitat Certification Program. Teach your neighbors and friends about  backyard habitats and help them certify their backyards! This program provides technical assistance to private property and small lot owners (less than one acre) to restore native wildlife habitat in their backyards and help manage on-site stormwater runoff.
