Andrews Forest LTER

Andrews Forest is a large wooded area in the Cascade Mountains that spans multiple elevation zones and is shaped by mountain streams and forested slopes. The property contains a network of research stations and monitoring instruments scattered throughout the landscape.

The forest was established as a research site in 1948 and later became a major scientific hub. In 1980, it joined an important national network dedicated to studying ecosystems over many decades.

The forest serves as a living classroom where researchers and students observe the connections between trees, water, and wildlife in real time. Visitors experience a place where science unfolds outdoors, with the ecosystem itself as the teaching ground.

Most areas of the forest are remote and require substantial walking to reach research zones. Visitors should prepare for uneven terrain, slippery paths during wet seasons, and dense undergrowth.

Within this forest grow Douglas fir trees older than 700 years, among the oldest trees in the region. These ancient trees provide insights into centuries of climate and fire patterns.
