Trees are important landscape features whether in the home garden, in community parks and open spaces, or on the grounds of historic or public buildings. Often long-lived and large in size, trees may serve as living markers of times gone by or notable places. They may be associated with historic persons or events, or they may be unusual by their presence in this part of the world.

The WSU Extension Clark County Master Gardener program maintains a list of trees of significance in unincorporated Clark County through its Heritage Tree Program.

How to Nominate a Tree

If you have or know of a special tree or a grove of trees that might be considered for Heritage Tree status, please review the program criteria listed below and contact the WSU Extension Clark County Master Gardener Program at  564-397-5738, or submit a Heritage Tree Nomination form to or in person at the Clark County Extension Office Master Gardener Program; 1919 NE 78th St., Vancouver, WA 98665.

Heritage Tree status may be granted to a tree or a collection of trees if they meet one or more of the following criteria:

  • Exceptional or unusual size, form, or rarity
  • Significant age
  • Association with a significant landmark, person, event or natural resource
  • Is considered a local landmark, visually accessible to public viewing
