The major feature in the Mt. Eddy Research Natural Area (MERNA) is Mt. Eddy at the northern end of the RNA. Mt. Eddy at 9025 ft (2751 m) is the highest peak in the Klamath Province. The MERNA also includes three ridges extending southerly from the summit of Mt. Eddy, one lies in the middle portion of the RNA and the other two constitute the RNA's western and eastern borders. The lowest elevation is approximately 6320 ft (1926 m) located in the southeast corner of the RNA. South facing slopes, ranging from 20 to 50 percent (11-27 degree), are dominant in the area.The vegetation is composed prim...

The dominant topographic characteristics of the area are the steep slopes and the two creeks that bisected them. Granite Creek flows into the RNA from the southwest side of section 17 and meets Swift creek in the northwest quarter of this same section. Swift Creek bisects the RNA and runs northwest to the southeast through section 17. At one location, Swift Creek has carved the bed rock into a 90 foot {27.4 m) deep gorge. Stream benches or flats exist along and above both banks of Swift Creek. Seeps and wet areas on these benches provide for a range of meadow types including dry meadow, moist ...

A stream inventory was conducted during the summer of 1995 on the upper reach of Caspar Creek beginning at the confluence with the unnamed tributary locally known as South Fork Caspar Creek. This section of Caspar Creek is locally known and hereafter referred to as North Fork Caspar Creek. The inventory was conducted in two parts: habitat inventory and biological inventory. The objective of the habitat inventory was to document the habitat available to anadromous salmonids in North Fork Caspar Creek. The objective of the biological inventory was to document presence and distribution of juvenil...

A stream inventory was conducted during the summer of 1995 on an unnamed tributary of Caspar Creek locally known and hereafter referred to as Middle Fork Caspar Creek. The inventory was conducted in two parts: habitat inventory and biological inventory. The objective of the habitat inventory was to document the habitat available to anadromous salmonids in Middle Fork Caspar Creek. The objective of the biological inventory was to document the presence and distribution of juvenile salmonid species. There is no known record of adult spawning surveys having been conducted on Middle Fork Caspar Cre...

A stream inventory was conducted during the summer of 1995 on Caspar Creek, starting at the Highway 1 bridge and ending at the confluence with the unnamed tributary designated locally as South Fork Caspar Creek. The inventory was conducted in two parts: habitat inventory and biological inventory. The objective of the habitat inventory was to document the habitat available to anadromous salmonids in Caspar Creek. The objective of the biological inventory was to document the presence and distribution of juvenile salmonid species. Adult spawning surveys, juvenile index reach surveys, and juvenile...

The Doll Basin Research Natural Area contains an excellent representation of the mixed conifer type for the North Coast Range Physiographic Province. The variation in dominance of the typical canopy species from ponderosa pine and black oak on the drier slopes to white fir and incense cedar on the northerly-facing slopes is indicative of the representative nature of the mixed conifer forests of the area. The additional relatively large areas of Douglas-fir and white fir-dominated forest on lower and upper slopes (respectively) enable the area to serve as a thorough representation of the mixed ...

The Hale Ridge Research Natural Area (HRRNA) is characterized by the presence of knobcone pine with transitions to mixed conifer forest, dominated by Douglas-fir, to the north and relatively diverse mixed chaparral, with transition to chamise chaparral, on the drier south-facing slopes. The entire RNA is also within a late successional reserve (RC313) to provide and protect habitat for northern spotted owl and other late successional forest dependent species. Graywacke sandstone and shales of the Franciscan Assemblage form the underlying geologic foundation of the HRRNA, with soils consisting ...
