This guidebook describes Forest Creeks Research Natural Area, a 164-ha (405-ac) 

area comprising two geographically distinct canyons and associated drainages. The 

two units have been established as examples of first- to third-order streams originating within a ponderosa pine (Pinus ponderosa) zone. The two riparian areas also 

represent examples of the mountain alder-redosier dogwood (Alnus incana-Cornus 

sericea ssp. sericea), and the redosier dogwood-mockorange (Cornus sericea ssp. 

sericea-Philadelphus lewisii) plant associations. 

Keywords: Research natural area, first- to third-order stream, mountain alderredosier dogwood plant association, Alnus incana-Cornus sericea ssp. sericea plant 

association, redosier dogwood-mockorange plant association, Cornus sericea ssp. 

sericea-Philadelphus lewisii plant association, riparian vegetation, area of critical

Preface

The research natural area (RNA) described in this supplement1 is administered by 

the Prineville District, Bureau of Land Management (BLM), U.S. Department of 

the Interior.

Scientists and educators wishing to visit or use the RNA for scientific or 

educational purposes should contact the Prineville BLM field office manager in 

advance and provide information about research or educational objectives, sampling 

procedures, and other prospective activities. Research projects, educational visits, 

and collection of specimens from the RNA all require prior approval. There may be 

limitations on research or educational activities.

Forest Creeks RNA is part of a federal system of such tracts established for 

research and educational purposes. Each RNA is a site where natural features are 

protected or managed for scientific purposes and natural processes are allowed to 

dominate. Their main purposes are to provide:

• Baseline areas against which effects of human activities can be measured or 

compared.

• Sites for study of natural processes in undisturbed ecosystems.

• Gene pool preserves for all types of organisms, especially rare and endangered types.

The federal system is outlined in A Directory of the Research Natural Areas on 

Federal Lands of the United States of America.

2 

Of the 183 federal RNAs established in Oregon and Washington, 45 are 

described in Federal Research Natural Areas in Oregon and Washington: A 

Guidebook for Scientists and Educators (see footnote 1). Supplements to the 

guidebook such as this publication constitute additions to this document.

The guiding principle in management of RNAs is to prevent unnatural 

encroachments or activities that directly or indirectly modify ecological processes 

or conditions. Logging and uncontrolled grazing are not allowed, for example, 

nor is public use that might impair scientific or educational values. Management 

practices necessary to maintain or restore ecosystems may be allowed (Wilson et al. 

2009).

Federal RNAs provide a unique system of publicly owned and protected 

examples of undisturbed ecosystems where scientists can conduct research with 

minimal interference and reasonable assurance that investments in long-term 

studies will not be lost to logging, land development, or similar activities. In 

return, a scientist wishing to use an RNA is obligated to:

• Obtain permission from the appropriate administering agency before using 

the area.3

• Abide by the administering agency’s regulations governing use, including 

specific limitations on the type of research, sampling methods, and other 

procedures.

• Inform the administering agency on progress of the research, published 

results, and disposition of collected materials.

The purpose of these limitations is to:

• Ensure that the scientific and educational values of the tract are not 

impaired.

• Accumulate a documented body of knowledge and information about the 

tract.

• Avoid conflict between studies and activities.

Research must be essentially nondestructive; destructive analysis of vegetation 

is generally not allowed, nor are studies requiring extensive modification of 

the forest floor or extensive excavation of soil. Collection of plant and animal 

specimens is generally restricted to the minimum necessary to provide voucher 

specimens and other research needs. Under no circumstances may collecting 

significantly reduce populations of species. Collecting must also be carried out in 

accordance with agency regulations. Within these broad guidelines, appropriate 

uses of RNAs are determined by the administering agency.

Research natural areas are available for short- or long-term scientific study, 

research, and education and serve as a baseline against which human impacts on 

natural ecosystems can be measured. 

3 Six federal agencies cooperate in this program in the Pacific Northwest: U.S. Department 

of the Interior, Bureau of Land Management, Fish and Wildlife Service, and National Park 

Service; U.S. Department of Agriculture, Forest Service; U.S. Department of Energy; 

and U.S. Department of Defense. In addition, the federal agencies cooperate with state 

agencies and private organizations in Oregon and Washington in the Pacific Northwest 

Interagency Natural Area Committee.

Forest Creeks Research Natural Area

Introduction

The paper is one of a series describing research natural areas in Oregon and Washington (see Franklin et al. 1972). Forest Creeks Research Natural Area (RNA) is 

a 164-ha (405-ac)1 area comprising two stream reaches within Fox Canyon and 

Rough Canyon, in Crook County, Oregon. Both drainages are tributaries to the 

North Fork Crooked River. These two units were established as a research natural 

area and as an area of critical environmental concern in 1989 with publication of 

the Brothers/LaPine Resource Management Plan Record of Decision (USDI BLM 

1989). This designation was reaffirmed in the 2005 Upper Deschutes Resource 

Management Plan (USDI BLM 2005).

The area was established to serve as an example of first- to third-order streams 

originating in a ponderosa pine (Pinus ponderosa) zone (see app. 1 for species 

names), and also to represent an example of the mountain alder-redosier dogwood 

(Alnus incana-Cornus sericea ssp. sericea), and the redosier dogwood-mockorange 

(Cornus sericea ssp. sericea-Philadelphus lewisii) riparian plant associations. The 

RNA is located in the extreme southern portion of the Blue Mountains Ecological 

Province in central Oregon (ONHP 2003).

Access and Accommodations

From downtown Prineville, Oregon, proceed east on U.S. Highway 26 to intersection with Combs Flat Road (State Route 380) (fig. 1). Turn south and proceed on 

paved road (not marked with highway signs after leaving Prineville) for 55.4 km 

(34.4 mi). Turn left (north) onto Teaters Road (gravel/dirt) and reset trip odometer to 

0. Proceed for 7.2 km (4.5 mi) and turn left at fork in the road. Continue for 2.3 km 

(1.4 mi) (9.5 km/5.9 mi on odometer) and take the right fork (do not take road 4235 

to the left) and proceed to 10.6 km (6.6 mi) on odometer over cattle guard and take a 

right turn. Continue to 12.4 km (7.7 mi) on odometer, and take the right fork (do not 

go uphill). At this point, there is a Bureau of Land Management (BLM) gate that is 

locked from December 1 to May 1 each year. Continue through the gate to 13.2 km 

(8.2 mi) on odometer, and take the left fork (do not go downhill at this point). Cross 

cattle guards at 14.0 km (8.7 mi), 15.4 km (9.6 mi), and 23.7 km (14.7 mi). At 25.7 

km (16.0 mi), stop and park vehicle. The Rough Canyon unit of the RNA is located 

south of the parking area in S30 T15S R22E (fig. 2).

1 These data are on file at the Prineville District office of the Bureau of Land Management, 

and at the USDA Forest Service, Pacific Northwest Research Station, Corvallis, Oregon.

GENERAL TECHNICAL REPORT PNW-GTR-813

To reach the Fox Canyon unit of the RNA, continue from the Rough Canyon 

parking area on the same road to 31.9 km (19.8 mi). Take the right fork, and continue to 33.3 km (20.7 mi) on the odometer. Park vehicle next to road, and walk 100 

m (328 ft) northeast to the rim of Fox Canyon RNA located in NW1⁄4 NW1⁄4 S30 

T15S R22E (fig. 2).

Permission to access the RNA for research or educational purposes is required 

prior to visiting the area. Inquiries should be directed to the Prineville District 

office, Bureau of Land Management in Prineville, Oregon. Road conditions and 

access can vary greatly with rain and snow conditions. Check with the Prineville 

District office prior to attempting access into the area. Lodging is available in 

Prineville, Oregon.

Environment

Elevations in the Rough Canyon unit range from 1201 m (3,940 ft) along the 

drainage channel in the southeast portion of the tract to 1372 m (4,500 ft) along 

the north-northwest boundary. Upper elevation slopes are gentle to moderate but 

drop more steeply into Rough Canyon along lower slope segments. Steep slopes are

typically composed of basalt talus. The Fox Canyon unit ranges from 1274 m (4,180 

ft) elevation in the drainage bottom along the east boundary of the tract to 1372 m 

(4,500 ft) in the northwestern part of the tract. Side-slope steepness and length are 

similar to those in the Rough Canyon unit (fig 2).

Slopes are oriented northwest-southeast, and streamflow is generally to the 

southeast in both units. Both drainage basins are dissected into gently sloping

plateaus. Canyon sides are typically steep, short headwalls, with moderate to long 

talus slopes leading into the intermittent streams within Fox Canyon and Rough 

Canyon. Approximately 0.8 km (0.5 mi) of each creekbed is seasonally dry each 

year. Water surfaces at bedrock in some reaches, and numerous pools form each 

year in bedrock depressions and temporarily impounded areas (fig. 3) (USDI BLM 

2009). 

Bedrock is composed of early to middle Miocene Picture Gorge basalt flows 

of aphyric and plagioclase porphyritic flood basalt (Swanson 1969, Walker and 

MacLeod 1991). Soils within the two units have been provisionally mapped and 

are composed of two main soil series: the Madeline series and the Lorella series. 

Two-thirds of the RNA is Lorella–Rock Complex series. A typical pedon is primarily Lorella very stony loam. The taxonomic class is clayey-skeletal, smectitic, 

mesic Lithic Argixerolls. The soil surface is covered with 20 percent cobbles and 30 

percent pebbles. The following is a generalized profile for Lorella very stony loam 

(USDA NRCS 2009): 

A1–0 to 5 cm (0 to 2 in) Very dark grayish brown (10YR 3/2) very stoney

loam

A2–5 to 13 cm (2 to 5 in) Very dark grayish brown (10YR 3/2) very gravelly

loam

BA–13 to 25 cm (5 to 10 in) Dark brown (10YR 4/4) very cobbly clay loam

Bt–25 to 48 cm (10 to 19 in) Dark yellowish brown (10YR 4/4) very cobbly clay

R–48 cm (19 in) Dark brown (10YR 4/3) fractured volcanic tuff

Climate

The RNA is situated in the Blue Mountains along the boundary of the Northern 

Great Basin ecoregion, and the Blue Mountains ecoregion (Franklin and Dyrness 

1988, ONHP 2003), and consequently exhibits climatic features of both. Summers 

are dry with warm days and moderate to cool nights. Frost occurs rarely during 

the summer but may occur anytime between October and June (Western Regional 

Climate Center 2009).

The weather station nearest to the RNA is PAULINA, OREGON (356500). Data 

collected from this station from 1961 to 2005 are summarized in table 1. Average 

annual precipitation of 286 mm (11.3 in) is probably a low estimate for the RNA 

given its location in the Blue Mountains. Twenty-five percent of annual precipitation 

occurs during the 3-month growing period from May through July. Snowfall may 

occur from October through April. Average annual snowfall is 566 mm (22.3 in). 

Average snow depth accumulations of 25 mm (1 in) occur from December through 

January (Western Regional Climate Center 2009). 

Vegetation

The RNA has biologic and geologic characteristics of both the Blue Mountains 

and Northern Great Basin ecoregions. A high percentage of the RNA flora occurs 

throughout central and south-central Oregon (app. 1).

Initial interest in establishing Forest Creeks RNA was because of its general 

hydrologic and geomorphic representation of first- and third-order streams originating within ponderosa pine forest. Subsequent refinement of vegetation-based 

wetland and riparian classifications led to more detailed classification and search for 

riparian, lacustrine, and palustrine plant associations (Crowe et al. 2004, Crowe and 

Clausnitzer 1997, Johnson 2004, Kovalchik 1987, Kovalchik and Clausnitzer 2004,

Wells 2006) listed in the Oregon Natural Heritage Plan (ONHP 2003). As a result, 

the RNA was also found suitable to represent two specific plant associations: 

1. Mountain alder–redosier dogwood (Alnus incana-Cornus sericea ssp. 

sericea) riparian association; and 

2. Redosier dogwood–mockorange (Cornus sericea ssp. sericea-Philadelphus 

lewisii riparian association (Crowe et al. 2004).

Vegetation in both the Rough Canyon and the Fox Canyon Creek drainages 

is highly variable. Roughly half of the stream reaches within Rough Canyon and 

Fox Canyon Creek are dominated by a tall shrub layer surrounding the channel 

comprising mountain alder, redosier dogwood, mockorange, water birch (Betula 

occidentalis), bitter cherry (Prunus emarginata), chokecherry (P. virginiana var. 

melanocarpa), and willow (Salix sp.) (fig. 4). These shrubs are also found in other 

mesic habitats throughout the RNA. Common herbaceous species include beaked 

sedge (Carex utriculata), smallwing sedge (C. microptera), fowl mannagrass 

(Glyceria striata), and Baltic rush (Juncus arcticus var. littoralis). A number of 

terrestrial vascular plants also add plant diversity to the RNA, including low 

sagebrush (Artemisia arbuscula), rigid sagebrush (A. rigida), sulphur-flower buckwheat (Eriogonum umbellatum), rock onion (Allium macrum), arrowleaf balsamroot 

(Balsamorhiza sagittata) (fig. 5), and the colorful wallflower phoenicaulis (Phoenicaulis cheiranthoides) (USDI BLM 1985).

Figure 4—Tall shrubs along Fox Canyon Creek including mountain alder (Alnus incana), bittercherry 

(Prunus emarginata), dogwood (Cornus sericea ssp. sericea), mockorange (Philadelphus lewisii), 

and water birch (Betula occidentalis).

Forest Creeks Research Natural Area

Although limited in size, many other terrestrial habitats and vegetation types 

that occur outside of the riparian zone contribute to a species-rich flora (app. 1) 

within the RNA. The most prominent of these are western juniper woodlands 

(Johnson and Swanson 2005), and the ponderosa pine/Idaho fescue (Pinus ponderosa/Festuca idahoensis) forest association (Johnson and Clausnitzer 1992). 

Appendix 1 lists scientific and common names of plant species known to occur 

within the RNA. 

Fauna

Reptiles, amphibians, birds, and mammals known or expected to occur within the 

RNA are listed in appendix 2. These lists have been derived from both field observation and published literature (Csuti et al. 1997).

Disturbance History

Summer storms and lightning are common in the Blue Mountains. There is scattered evidence of past lightning ignitions in small areas of the RNA (USDI BLM 

2009). However, the extensive rock outcrops and sparsely vegetated talus slopes 

(fig. 6) limit spread of fire from adjacent uplands. The historical role of fire has not 

been examined in this area.

GENERAL TECHNICAL REPORT PNW-GTR-813

The role of anthropogenic disturbance owing to grazing by domestic livestock 

appears to have played only a minor role within the RNA. The very sparse abundance of invasive species within the riparian zone suggests that the rocky and often 

steep terrain may have inhibited livestock movement.
