Wilsonville Heritage Tree Program

Three Sisters Oaks (Quercus garryana) on private property on SW Kinsman Road at SW Gaylord Way.


In 2004, when City Councilor Charlotte Lehan served as Mayor, the City's Heritage Tree Program was established to recognize trees that have historical significance or were planted by (or in honor of) someone who advanced the interest of trees and plants in the community. Trees can also be recognized for a significant role in landscape architecture, forestry, city planning, and culture.

The first tree designated, in 2004, was the Ernest Kolbe Giant Sequoia (Sequoiadendron giganteum). Planted by long-time Wilsonville resident and forestry expert Ernest Kolbe (1903-1978), this tree is located next to his former homestead on the east side of Memorial Park.

The most recent designation, in 2017, is the Three Sisters Oaks. From 160 to 210 years old, these three Oregon white oaks (Quercus garryana) stand tall and proud in a stately row on private property on SW Kinsman Road at SW Gaylord Way.

You can learn all about Wilsonville's Heritage Trees and some local history by viewing the virtual tour. Just follow this link and enjoy!

Wilsonville has thousands of trees, but only 10 trees or groves are recognized City Heritage Trees. Between 2004 and 2009, nine trees or groves were designated, but only one small grove has been added since. To bring new life to the Heritage Tree Program in 2020, the City has rolled out a new logo and launched this page on Let’s Talk, Wilsonville! The City is now actively seeking nominations of trees of special significance that tell a story of local history or provide a connection to the community’s heritage.

If you think a tree or grove would be a good candidate for Heritage Tree designation, the City welcomes nominations. To nominate a tree or learn more, follow this link.

Every tree has a unique story. The problem is that they cannot speak, so community members have to tell their stories for them. 

There are stories about Wilsonville's Heritage Trees in the virtual tour, but there are more to tell, and the City would like to invite you to introduce other unique trees to the community. 

Tell a unique tree story here on Let’s Talk, Wilsonville!
