Weyerhaeuser Co, Castle Rock

At Weyerhaeuser, we’re proud of what we do and how we do it, and we invite you to learn more.

Over several decades, we measured hundreds of thousands of trees and a small percentage were selected for the best growth. Through grafting, interbreeding and testing, we’ve developed some of the best performing seed in the world today.
Our high-yield Weyerhaeuser Select genetically improved Douglas fir seed is available for sale to reforestation customers in British Columbia, Washington and Western Oregon. None of our seed imates similar to areas to be planted.
Within typical sites found below 2, 000' on the west side of the Cascade mountain range, research shows that seed from the best parents tends to produce good-performing stands, even on sites more than 100 miles from the parents' origin. Field trials show you can expect much higher yield and value in your timber harvest, with the amount depending on the quality and intensity of stand management.
