Churn Creek Protected Area: Mapping the Grasslands and Canyons of the Chilcotin Plateau

Long before it was a protected area, the Churn Creek landscape was shaped by thousands of years of human presence. Tsilhqot'in and Secwepemc First Nations people inhabited the area for at least 7,000 years, with communities such as the Tcexwe'ptem band using the Empire Valley. The arrival of Europeans in the wake of the mid-1800s Cariboo gold rush disrupted this Indigenous landscape profoundly. Smallpox, previously unknown to local peoples, devastated the Tcexwe'ptem in the 1860s, and survivors joined the Canoe and Dog Creek bands to the east.

In the late nineteenth century, ranching emerged as the dominant European land use in the region. Two large operations, the Empire Valley Ranch and the historic Gang Ranch, were established around Churn Creek and defined the working landscape well into the twentieth century.

The movement to protect Churn Creek began with national-level interest. Parks Canada identified the area as a potential national park because of its bighorn sheep populations and other wildlife values, but local ranching opposition halted that effort. After the Province of British Columbia completed a regional environmental assessment of the Cariboo in the 1990s, attention returned to Churn Creek. Rather than removing grazing from the landscape, the province negotiated a compromise that allowed cattle to continue on designated areas within the park. Churn Creek Protected Area was officially designated in 1995, and in 1997 the former Empire Valley ranch lands were added, expanding its footprint and consolidating grassland protection in the region.

The Churn Creek landscape is defined by the interplay between arid plateau country and deep river-carved canyons. The protected area occupies the southern margin of the Chilcotin Plateau, where rivers and creeks have incised the surface into a complex of benches, gullies, and steep-walled drainages. Churn Creek's own canyon is one of the most visually striking features, eroded into pillars and hoodoos that stand out against the otherwise open terrain.

Along the eastern edge, the Fraser River forms a long boundary, and the southern portion of the protected area follows the river's western bank into the lower Grinder and Lone Cabin Creek drainages. Several small lakes dot the otherwise dry landscape. To the west, the land rises sharply into the Camelsfoot Range, with elevations above 1,500 meters forming a dramatic backdrop and creating a clear altitudinal transition from steppe to forested ridge and alpine habitat.

The resulting scenery is open and expansive, with grasslands giving way to forested draws, rimrock, and canyon headwalls within short distances. This juxtaposition of dryland and canyon topography is one of the defining visual characteristics of Churn Creek.

Churn Creek Protected Area protects one of the most ecologically distinctive settings in British Columbia: an interior dryland steppe that sits beside, and depends on, surrounding forest, canyon, and riparian habitats. At lower elevations, the grasslands are dominated by bluebunch wheatgrass, with big sagebrush forming characteristic clumps across the benchlands. A particularly notable feature of these grasslands is the dense ground cover of lichens and mosses, which can blanket up to eighty percent of the surface beneath and between the vascular plants.

Where elevation increases, the open steppe shifts into Interior Douglas fir forest, while along rivers, creeks, and small lakes, deciduous trees such as aspen and poplar form copses and gallery stands. Together these vegetation layers create a grassland-forest mosaic that supports a wide range of wildlife and that is increasingly rare in a province where fire suppression and land use have reduced natural grassland extent.

The park's ecological significance is amplified by its protected status: Churn Creek is one of only five provincial parks in British Columbia dedicated specifically to grassland conservation, making it a critical refuge for arid-land habitats at this latitude.

Wildlife is central to Churn Creek's identity and was the original reason Parks Canada evaluated the area for protection. California bighorn sheep are the area's most conspicuous residents. Several herds live within the protected area, some remaining year-round on the benchlands and others moving seasonally into nearby alpine country during the summer.

Mule deer are also well established in the park, sharing the open terrain with the bighorn. The grassland environment supports a rich community of smaller fauna, including bats, small rodents, and reptiles. Birdlife is particularly diverse. Grassland specialists such as Brewer's sparrow, long-billed curlew, and prairie falcon are joined by species such as Lewis's woodpecker, gyrfalcon, and short-eared owl. Recorded bats include the Western small-footed myotis, while reptiles include the rubber boa and gopher snake.

In the forested portions of the reserve, the fauna shifts accordingly. Forest-dependent species such as flammulated owl, Townsend's big-eared bat, and sharp-tailed grouse occupy the woodland habitat, rounding out a wildlife community that spans the gradient between dry steppe and forested uplands.

Churn Creek Protected Area exists primarily to safeguard one of British Columbia's rarest ecosystems: interior dryland grassland. Although the broader province is dominated by coniferous forest, the arid steppe country at Churn Creek represents a vanishingly small share of the total landscape. The reserve protects the watershed of Churn Creek, substantial frontage on the Fraser River, and important Canadian bighorn sheep habitat under a single designation.

Its IUCN Category VI status, which permits sustainable use of natural resources, reflects a deliberate compromise between ecological protection and the area's long ranching history. Designated grazing zones allow cattle to remain on the landscape while still maintaining the grassland communities that prompted protection in the first place. This arrangement is part of why the area transitioned from a proposed national park into a provincially managed protected area.

Churn Creek's conservation importance is also recognized through its inclusion among only five provincial parks in British Columbia specifically dedicated to preserving grassland ecosystems. The 1997 expansion to include the former Empire Valley Ranch lands further strengthened that role by bringing additional contiguous steppe and canyon habitat under protection.

Churn Creek carries a layered human history that stretches back thousands of years. Tsilhqot'in and Secwepemc First Nations peoples used and inhabited the area for at least seven millennia, with groups such as the Tcexwe'ptem occupying the Empire Valley. The second half of the nineteenth century brought profound disruption through the Cariboo gold rush and the introduction of smallpox, which decimated Indigenous communities and reshaped regional demographics.

European settlement introduced a new land use based on large-scale cattle ranching. Operations such as the Gang Ranch and Empire Valley Ranch defined the post-1860s cultural landscape around Churn Creek, and elements of that ranching heritage remain visible today. The historic Gang Ranch lies just north of the protected area, and the Empire Valley Ranch lands were absorbed into the park during its 1997 expansion.

The continuing presence of cattle within designated grazing zones means Churn Creek is still a working landscape as well as a protected one, a feature that is now part of the area's identity rather than an obstacle to its conservation mandate.

Churn Creek Protected Area is the place to encounter one of British Columbia's rarest ecological settings: a large, intact dryland steppe and canyon system sitting above the Fraser River. The combination of bluebunch wheatgrass grasslands, sagebrush stands, lichen-covered ground, and deeply eroded canyon features such as hoodoos gives the area a character found almost nowhere else in the province.

Its wildlife profile is equally distinctive, with resident California bighorn sheep herds, mule deer on the open benches, and a rich grassland bird community that includes long-billed curlew, Brewer's sparrow, and Lewis's woodpecker. Together with the surrounding Camelsfoot Range and the long sweep of the Fraser River shoreline, Churn Creek offers an unusually complete picture of south-central British Columbia's natural and human past.

Spring and early summer are generally the most rewarding seasons at Churn Creek, when the grasslands are green, wildflowers and sagebrush are actively growing, and grassland birds are most active. Cooler temperatures also make longer exploration of the open benchlands more comfortable.

Late summer and early autumn bring dry, warm conditions and a more golden character to the steppe, while also offering the best chances to observe bighorn sheep concentrated near water. Winters can be cold and snowy at higher elevations in the Camelsfoot Range, and access to canyon and rangeland areas typically becomes more limited under snow.
