Description:
The Andrews Forest is situated in the western Cascade Range of Oregon in the 15,800-acre (6400-ha) drainage basin of Lookout Creek, a tributary of Blue River and the McKenzie River. Elevation ranges from 1350 feet (410 m) to 5340 feet (1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. The research program has been diverse throughout the history of the Forest, with the dominant themes changing over the years. Today, several dozen university and federal scientists use this LTER site as a common meeting ground, working together to gain basic understanding of ecosystems and to apply this new knowledge in management policy. Read More

History:
The H.J. Andrews Experimental Forest was established by the U.S. Forest Service in 1948. Over the more than 60 years since its inception, it has had a rich and diverse research history, with major research foci changing over time. Read More
