Siuslaw National Forest (pronounced /sаɪˈjuːslɔː/, or, for native English speakers, sigh YEW slaw)[2] is a national forest in western Oregon, United States. Established in 1908, the Siuslaw is made up of a wide variety of ecosystems, ranging from coastal forests to sand dunes.



The Siuslaw National Forest encompasses more than 630,000 acres (2,500 km2) along the central Oregon Coast, between Coos Bay and Tillamook,[3] and in some places extends east from the ocean, beyond the crest of the Oregon Coast Range, almost reaching the Willamette Valley.[4] The Forest lies primarily in Lane (39% of the forest) and Lincoln (27% of the forest) counties; the rest in descending order of land area are Tillamook, Douglas, Yamhill, Benton, Coos, and Polk counties.[5] It includes the Sand Lake Recreation Area and the Oregon Dunes National Recreation Area. The Forest Supervisor's office is located in Corvallis, Oregon, and the Siuslaw is broken up into two ranger districts - the Hebo Ranger District, with approximately 151,000 acres (610 km2), and the Central Coast Ranger District, with approximately 479,000 acres (1,940 km2).[6]

Points of interest

Sand dunes at Oregon Dunes National Recreation Area.

The Forest contains Marys Peak, the highest point in Oregon's Coast Range at 4097 ft (1249 m). Numerous aquatic habitats are found in the forest: marine shore, rivers and streams (1,200 miles, including the Alsea, Nestucca, Siuslaw, and Umpqua rivers), and 30 lakes.[4] The terrestrial environment can be regarded as two major vegetation zones, one near the coast dominated by Sitka Spruce (Picea sitchensis), and the other dominated by Western Hemlock (Tsuga heterophylla) and Douglas Fir (Pseudotsuga menziesii). A 1993 Forest Service study estimated that the extent of old growth in the Forest was 33,800 acres (13,700 ha).[7] Cummins Creek and Rock Creek Wildernesses preserve some of this old growth.

Recreational activities

Recreational activities in the Siuslaw National Forest include fishing, camping, hiking, horseback riding, mountain biking, exploring tide pools, and riding off highway vehicles.
