This guidebook describes Woodcock Bog Research Natural Area (RNA), 

a 114-ha (281-ac) area located within the Klamath-Siskiyou ecoregion in 

southwestern Oregon. The RNA includes a hanging fen and stream segment on 

ultramafic rock and derived soils. Numerous plant species occur within the fens 

that are endemic to the Klamath-Siskiyou Mountains of southwestern Oregon and 

northwestern California. Cobra lily (Darlingtonia californica), and sedges (Carex

spp.) characterize the area. The site also supports very dry, open serpentine forest 

stands of Jeffrey pine (Pinus jeffreyi), along with denser stands of Port-Orfordcedar (Chamaecyparis lawsoniana), Douglas-fir (Pseudotsuga menziesii), and other 

conifers typical of the region.

Preface

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

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

Interior.

Woodcock Bog RNA is part of a federal system2 of natural areas established 

for research and educational purposes (Federal Committee on Ecological Reserves 

1977). 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 (1972). This report is a supplement to the 

guidebook. 

Each RNA is a site where elements3

 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 for those that are 

rare and endangered.

The guiding principle in managing RNAs is to maintain natural ecological 

processes or conditions for which the sites were designated. Timber harvesting and 

uncontrolled grazing are not allowed, nor is public use that might impair scientific 

or educational values. Management practices necessary to maintain or restore 

ecosystems may be allowed (see footnote 2).

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. Scientists 

and educators wishing to visit or use the Woodcock Bog RNA for scientific or 

educational purposes should contact the Medford BLM District 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.

A scientist or educator wishing to use the RNA is obligated to:

• Obtain permission from the appropriate administering agency before using 

the area (see footnote 2).

• 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 this approval process is to:

• Ensure that the ecological integrity, and scientific and educational values of 

the tract are not compromised.

• Allow the agency to document research or educational use of the tract.

• Help promote the dissemination and use of information collected at the site.

• Avoid conflict between ongoing studies and activities.

Appropriate uses of RNAs are determined by the administering agency. 

Destructive analysis of vegetation is generally not allowed, nor are studies requiring extensive substrate modification such as extensive soil excavation. Collection 

of plant and animal specimens is generally restricted to voucher specimens or 

approved research activities. Under no circumstances may collecting significantly 

reduce species populations. Collecting must also be carried out in accordance with 

all other federal and state agency regulations.

Woodcock Bog Research Natural Area

Introduction

Woodcock Bog Research Natural Area (RNA) is a 114-ha (281-ac) area located in 

Josephine County, Oregon, near the town of Cave Junction (fig. 1). The site was 

established as a research natural area in 1981 by the Bureau of Land Management 

(BLM) (USDI BLM 1981). The designation was reaffirmed in the Medford District 

resource management plan (USDI BLM 1995). 

In spite of its name, Woodcock Bog represents an outstanding example of 

a hanging fen1 on ultramafic rock and derived soils. The site also supports an 

example of a very dry serpentine site, with open forest stands of Jeffrey pine (Pinus 

jeffreyi), and denser stands of Port-Orford-cedar (Chamaecyparis lawsoniana), 

Douglas-fir (Pseudotsuga menziesii), and other conifers typical of the Siskiyou

1 A fen is a groundwater-fed wetland ecosystem that has neutral or alkaline water chemistry. A hanging fen occurs on sloping topographic surfaces. Fens differ from bogs, which 

are fed primarily by rainwater and have acidic water chemistry.

GENERAL TECHNICAL REPORT PNW-GTR-824

Mountains of southwestern Oregon. A population of purple-flowered rush-lily 

(Hastingsia atropurpurea) is present along with numerous other plant species 

endemic to southwestern Oregon (Becking 1986, 1997) (see appendix 1 for scientific names) (table 1). 

From a statewide perspective, Woodcock Bog contains examples of elements 

listed in the Oregon Natural Heritage Plan (ONHP 2003). Elements present at 

Woodcock Bog that are listed in the plan as requiring representation within the 

Klamath-Siskiyou ecoregion include:

• Darlingtonia fen on serpentine-peridotite, with western azalea 

and camas along margins. 

• Riparian on serpentine-peridotite, with Port-Orford-cedar, western 

azalea and cobra lily—a 0.4-km (0.25-mi) stream segment.

• Jeffrey pine with incense cedar and dry shrubs—a small stand.

Access and Accommodations

The site is located 3 miles (5 km) south-southwest of Cave Junction, Oregon, in 

Josephine County (fig 1). Access into the RNA crosses private land and is coordinated by the BLM. Permission to access the area for research or educational purposes should be obtained from the Medford District office prior to visiting the site. 

Access details will be provided by the BLM upon approval of a request. Lodging is 

available in Cave Junction, and Grants Pass, Oregon.

Environment

The RNA is situated along the lower slopes of Woodcock Mountain. Elevations 

within the site range from 448 m (1,470 ft) in the southeast to 856 m (2,810 ft) in the

northeast. Slopes are oriented east to southeast and are moderately inclined (20 to 

50 percent). Woodcock Creek is a perennial stream and flows southeast through the 

southern portion of the RNA (fig 2).

Underlying rocks include the 100-million-year-old Jurassic Galice formation, 

which is best exposed along Woodcock Creek (Wells 1953). Jurassic peridotite, 

about 136 to 190 million years old, occurs on the lower slopes of Woodcock Mountain. The peridotite is partially altered to serpentine. The peridotites are highly 

weathered and contribute to the rocky soils present on the site today. Several faults 

occur within the peridotites and are marked by zones of intensely sheared serpentine with freshwater springs that rise along the faults (Ramp 1978).

Soil parent material is colluvium and residuum derived from serpentinite and 

peridotite. Gently inclined slopes are mapped in the Eightlar series and the Brockman series. Steeper slopes are mapped as the Pearsoll-Rock outcrop complex. A 

typical profile of the Eightlar extremely stony clay, with 20- to 35-percent slopes is 

as follows (USDA NRCS 2009): 0 to 254 mm (0 to 10 in) extremely stony clay; 254 

to 1549 mm (10 to 61 in) very stony clay.

Climate

The climate is typical of inland valleys within the Klamath ecoregion of southwestern Oregon (Franklin and Dyrness 1988, ONHP 2003). Summers are warm to 

hot, and dry. Extended periods of drought during the summer months are common. 

Winters are cool and moist. Some winter precipitation occurs as snow, although 

the snowpack at lower elevations is often of short duration. The weather station 

nearest to the RNA is the Cave Junction, Oregon (351448) weather station, located 

about 5 miles to the north of Woodcock Bog at similar elevation. Average summer 

maximum temperatures of 32.1  ̊C (89.8  ̊F) occur in July. Average winter minimum 

temperatures of 0.4 ̊ C (32.7 ̊F) occur in January. Average annual precipitation is 

1553 mm (61.14 in). Six percent of annual precipitation occurs during the 4-month 

growing period from May through August. Snowfall may occur from November 

through April, but the majority of snowfall occurs between December and the 

end of February. Average annual snowfall is 384 mm (15.1 in) (Western Regional 

Climate Center 2009). 

Vegetation

Rock and soil chemistry strongly influence vegetation patterns within the KlamathSiskiyou Mountains (Coleman and Kruckeberg 1999) and within the RNA. Hanging fens occur along the east and southeast slopes of Woodcock Mountain (fig. 3). 

Fen vegetation is distinguished by cobra lily (Darlingtonia californica) (fig. 4). 

The groundwater fen wetlands originate from springs and seeps that emerge from 

fractures in the serpentine bedrock. The fens are interspersed with dry, forested 

areas dominated by Jeffrey pine (Pinus jeffreyi), Port-Orford-cedar (Chamaecyparis 

lawsoniana), and in places, incense cedar (Calocedrus decurrens). Brewer’s white 

oak (Quercus garryana var. breweri), a shrub endemic to the Klamath-Siskiyou 

ecoregion, occupies small ridges along the lower slopes.

The serpentine fens support one of the most distinctive plant communities of 

the Klamath-Siskiyou ecoregion in southwest Oregon and northwest California. 

These communities, typically dominated by the insect-trapping cobra lily, occur 

in areas where cold water flows year-round over soils derived from ultramafic or 

serpentine parent materials. Serpentine-derived substrates cover large areas in 

the Siskiyou Mountains and support a unique and diverse vascular flora including 

a high proportion of edaphic, endemic species (Coleman and Kruckeberg 1999, 

Frost et al. 2004). These patchy habitats occur as relatively small “green islands” 

surrounded by dry forest communities that support strikingly different types of 

vegetation (Frost et al. 2004).

GENERAL TECHNICAL REPORT PNW-GTR-824

Serpentine fens are particularly valuable as research natural areas because they 

provide habitat for concentrations of locally endemic plant species having limited 

natural ranges and narrow habitat requirements (table 1).

Three, 80-m (262 ft)-long transects were established in 2009 to monitor 

long-term trends of plant species. Both physical attributes and vegetation were 

documented (tables 2 and 3). Trees were widely scattered throughout the fens 

(front cover). Tree seedlings were very sparse, and tree regeneration in these areas 

appeared to be episodic. Shrubs were a conspicuous component in two of the three 

transects. The showy western azalea (fig. 5) was the only shrub present in all three 

transects, ranging from less than 1 to 14 percent cover, respectively. Cobra lily was 

a major herbaceous species present on all three transects, along with Josephine 

horkelia (Horkelia congesta ssp. nemorosa), western burnet (Sanguisorba annua), 

and three sedge species: Mendocino sedge (Carex mendocinensis), star sedge (C. 

echinata), and slenderbeak sedge (C. athrostachya). Trees are widely scattered, and 

low to tall shrubs, sedges, and a variety of showy herbaceous species occupy the 

area (fig. 6). The overall aspect of the fen is an open, elongated green garland that 

follows seepage courses downslope from their spring source areas.

A concentration of regionally endemic, special status plant species also 

occurred within the RNA (table 1). Some populations occur along vegetationmonitoring transects (tables 2, 3). A list of vascular plant species documented to 

occur within the RNA is provided in appendix 1.

Woodcock Bog Research Natural Area

Fauna

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

RNA are listed in appendix 2. These lists were derived from both field observation 

and published literature (Csuti et al.1997).

Disturbance History

Port-Orford-cedar root disease is present at Woodcock Bog. It is highly contagious 

and caused by the fungus Phytophthora lateralis. Unlike many other fungal spores 

that are spread by wind, P. lateralis depends on free water for spread and infection. 

It can also be unintentionally transported by humans through contact with clothing 

and footwear. Infection of trees can be avoided by minimizing and isolating sources 

of infection, preventing the movement of soil and water from infected to uninfected 

areas, and by reducing human contact (Roth et al. 1987). Restricting movement and 

activities of humans is the primary control method used at Woodcock Bog RNA. 

This includes closing roads to travel and sanitizing boots, tools, and clothing when 

leaving infected areas.

Lightning-ignited fire is a common occurrence in the forests of southwestern 

Oregon (Martin 1997). Although the fire landscape has changed since Native 

Americans burned prairies and woodlands prior to Euro-American settlement of the 

region, fire remains an integral part of the ecology of many terrestrial vegetation 

types, including fens surrounded by dry, Jeffrey pine forest.

No extensive fires have burned into the Woodcock Bog RNA in recent years. 

However, large wildfires, such as the Biscuit Fire (Cramer 2005), have recently 

burned extensive areas within the Klamath-Siskiyou region. Important decisions 

regarding the role of fire in maintaining natural processes will define stewardship 

management of research natural areas into the future (Wilson et al. 2009).

Research History

Data have been collected at Woodcock Bog RNA by researchers from a variety of 

disciplines, including ethnobotany (Lang 1997), plant systematics (Becking 1986), 

and plant ecology (Becking 1997, Coleman and Kruckeberg 1999, Cramer 2005, 

Frost et al. 2004).
