Liard
River Corridor Provincial Park
History
The Liard River
was the focus of a potential BC Hydro development for many years.
In 1992, this section of the Liard was identified as an Area of
Interest (AOI) to the Protected Areas Strategy, and was subsequently
officially included in 1995 as the Grayling-Liard River AOI. The
Fort Nelson Land and Resource Management Plan later established
protected status for this area in 1997.
Cultural
Heritage
The Liard River
Corridor overlaps with traditional use territories of the Kaska
Dene First Nations of McDonald River, Fireside and Lower Post; and
the Slavey Cree and Beaver Cultures of Fort Liard and Fort nelson
Indian Bands. Moose was a mainstay of the aboriginal people and
they historically utilized the river corridors.
Conservation
Liard River
Corridor Park encompasses the river valley and uplands to the height-of-land
on both the north and south sides of the river from the Liard River
Hotsprings to as far east as Scatter River Old Growth Park. The
Liard River forms the southern boundary of the Mackenzie Mountains,
separating the lower heights of the Liard Plateau from the higher
elevations of the Rocky Mountains to the south. The river descends
about 150 m in elevation from west to east within the park.
The park provides
representation of the Hyland Highland, Muskwa Foothills and the
Muskwa Plateau ecosections. An extensive high upland plateau characterizes
the Hyland Highland. Lower in elevation, the Muskwa Plateau is dominated
by boreal mixed wood forests and intermittent areas of muskeg. Subdued
mountains isolated by wide valleys typify the Muskwa Foothills.
Elevational
gradients in the park vary from 1000 m to 1300 m along the river
bottom to 2500 m to 3500 m along the height-of-land. The Liard River
Corridor includes the Grand Canyon of the Liard, a 30 km stretch
of river with dangerous rapids that includes the Rapids of the Drowned
and Hell's Gates Rapids.
The entire area
of the park was covered with ice during the last ice age and present
landscape is a product of those glacial processes. Fossilized ammonites
up to 30 cm in diameter have been found in several creeks that flow
into the Liard River.
Important tributaries
of the Liard River within the park include the Deer, Grayling, Toad
and Scatter Rivers; and Canyon, Moule, Sulphur, Brimstone, Crusty,
Graybank and Chimney Creeks. Several smaller lakes, including Norquist
and Aline Lakes, can be found in the lowlands north of the Grand
Canyon of the Liard.
Ranges in elevation
between valley bottom to mountain peaks support three biogeoclimatic
zones within the Liard River Corridor Park. The Boreal White and
Black Spruce zone dominates and is found along the entire Liard
valley, as well as its tributaries. Old-growth white spruce forests
are found in alluvial areas along the bottom of the Liard River.
The western half of this zone experiences drier and colder weather
and as a result, forest stands are predominately composed of white
spruce and lodgepole pine; soopolallie, bunchberry, bastard toadflax
are common understory species. In contrast, the moist, warm climate
of the eastern half supports forests stands of white spruce and
aspen with understory vegetation of highbush cranberry, rose, twinflower
and bunchberry. The Spruce-Willow-Birch and the Alpine Tundra zones
are found in small, isolated patches at the height-of-land on both
the north and south sides of the Liard River.
Wildlife
The park is
home to a diverse variety of wildlife species. The most unique species
found in the park is a free-ranging herd of wood bison, which inhabit
the forested areas in the western portion north of the Liard River.
The park is also home to moose, grizzly bear, Rocky Mountain elk,
furbearers, and northern long-eared bats.
Fishery values
along the Liard River are high. Twelve species of fish have been
identified, including the only known anadromous salmonid (chum salmon)
in northern BC. Sport fish species include arctic grayling, chum
salmon, bull trout, inconnu, lake whitefish, mountain whitefish,
northern pike and burbot. Other non-game fish consist of the long
nose sucker, lake chub, flat head chub, slimy sculpin, white sucker,
round whitefish and the long nose dace.
