About Thrall Preserve

 

Thrall Preserve is a nature preserve located in southern Oregon that protects a diverse ecosystem characterized by old-growth forests, volcanic rock formations, and riparian habitats. The preserve sits on land primarily shaped by past volcanic activity, which has created dramatic basalt cliffs and striking geological outcrops. The thriving forests are dominated by Douglas fir, ponderosa pine, and incense cedar, providing habitat for deer, black bears, numerous bird species, and other wildlife. The preserve was established to conserve these important ecological communities and to provide outdoor enthusiasts a chance to experience unaltered Pacific Northwest forest landscapes. Visitors can explore a network of moderate-length hiking trails that pass through mixed conifer forests and along streams, where seasonal wildflowers bloom and native wildlife can often be observed. Photography is a popular activity here, especially around the rugged rock formations and scenic viewpoints. The preserve is less frequented than nearby national parks, making it a peaceful destination for birdwatchers and those seeking solitude in nature. Education about local ecology and geology is also a thematic focus, with informational signage at trailheads and viewpoints. Overall, Thrall Preserve appeals to hikers, naturalists, and photographers interested in exploring an intact Oregon forest environment with remarkable volcanic geologic features.
