Natural Resources Program

Gresham is rich in natural beauty, with 900 acres of open space, 300 acres of parks, and 10 miles of trails. These natural areas are also rich in ecological diversity, and include forests, wetlands, farm land, rocky buttes and several streams and ponds. The City’s Natural Resources Program works to protect and restore these resources by building wildlife habitats, reporting and restoring degraded natural areas, and conducting wildlife surveys.

Gresham area residents play a large role in this work. Natural Resources' staff work closely with citizen volunteers to make a positive impact on public natural areas.  

Since 2002, volunteers and the City’s AmeriCorps members have:

  • Planted more than 115,000 native trees and shrubs
  • Restored 56 natural area sites 
  • Documented 300 wildlife species
  • Removed more than 11,000 pounds of trash from streams
  • Built and installed more than 200 shelters for birds, bats and flying squirrels

Join us in planting native species, remove invasive weeds, and learn about birds, fish, and other wildlife right in your backyard.
