We need your help measuring urban trees.


Our current research effort is Resilient Trees 3.0, and we need your help to measure 10 unique tree species by June 2017.

Operation Resilient Trees collects data on tree health, trunk and canopy size, GPS coordinates, and % permeable surface for 10 tree species that have widespread planting implications for our region:

  • Canary Island Pine (Pinus canariensis)
  • American Sweetgum (Liquidambar styraciflua)
  • Honey Locust (Gleditsia triacanthos)*
  • Brazilian Pepper Tree (Schinus terebinthifolia)
  • Red Ironbark (Eucalyptus sideroxylon)
  • Broad-leaved Paperbark (Melaleuca quinquenervia)
  • Kurrajong (Brachychiton populneus)
  • Chinese Banyan (Ficus microcarpa)*
  • Chinese Elm (Ulmus parvifolia)
  • Camphor Tree (Cinnammum camphora)

Join us in conducting valuable scientific research on urban trees in your community by joining a collection event.
