Project Summary & Public Benefits

One of many popular trails at Jenkins Estate.

The 68-acre Jenkins Estate on the northwest slope of Cooper Mountain in Aloha offers an exceptional opportunity for those seeking outdoor recreation. With several walking trails through the forested acreage, gardens near the restored country estate and wildflower meadows, Jenkins Estate is a jewel in THPRD's crown.

Phase I

Over the years, non-native plants have invaded the forested areas. With funds from the 2008 voter-approved bond, THPRD's Natural Resources Department completed the first of a two-phase restoration project at Jenkins Estate.

Phase I of the restoration project took place from June 2012 through early Spring 2013. Invasive blackberry, ivy, holly, hawthorn, cherry and other weedy species were removed before contractors installed 32,000 native trees and shrubs

Same area after completion of the Phase I restoration project.

To enhance visitor experiences and create larger blocks for wildlife habitat, illegal trails were either removed or rerouted, some new trails were built, and some existing trails were enhanced.

Update

Jenkins Estate is looking great!  Populations of ivy, holly, and other targeted non-native vegetation are greatly reduced (and meeting project objectives for non-native cover), and installed native trees and shrubs are healthy and thriving.  With the removal of the dense ivy ground cover, spring wildflowers populations have rebounded at Jenkins Estate. 

Now that the area has been treated by contractors, THPRD's Natural Resource Staff will continue to monitor and maintain the project area.

Project Budget

$135,200
