| SPLIT
LAKE RESOURCE MANAGEMENT AREA (SLRMA) |
As part of the 1992 Comprehensive Implementation Agreement, Tataskweyak
Cree Nation (TCN) and Manitoba agreed to jointly designate a Split Lake
Resource Management Area (SLRMA) for the purpose of integrated land use
and resource management planning and implementation. A map of the area
accompanies this article. All of Tataskweyak’s
Reserve Lands (Map 1) are in the SLRMA, together
with Manitoba Crown lands. The SLRMA encompasses part of the traditional
territory of the Tataskweyak Cree.
Split Lake Resource Management
Area (SLRMA) is a huge area of northeastern Manitoba, covering more than
16,000 square miles or 10 million acres. It represents over 6% of the
whole land and water area of the Province of Manitoba. The SLRMA is rich
in natural resources including clean water, fish, moose, caribou, birds,
bear, forests, medicinal plants, and minerals, to name a few of the resources.
The land is largely undeveloped, having only one main road linking Thompson
in the west to Split Lake, Gillam and Bird. Winter roads connect to York
Landing (York Factory First Nation), War Lake First Nation and Ilford.
To put the size of the SLRMA
into perspective: |
- It about the same size as
Denmark (16, 629 square miles);
- It is a little larger than
Switzerland and much larger than Belgium;
- It is somewhat larger than
Connecticut, Massachusetts and Rhode Island combined;
- It is 70% larger than Lake
Winnipeg (9,460 square miles), Manitoba’s most prominent geographical
feature; and
- It is about the same size
as Lake Erie and Lake Ontario combined.

| Terrestrial
Ecozones and Ecoregions of the Split Lake Resource Management Area |
The SLRMA is interesting from
an ecological perspective. At the most general level of ecological classification,
there are six Ecozones in Canada and three of them occur in the SLRMA! These
are: Hudson Plains Ecozone, Boreal Shield Ecozone, and Taiga Shield Ecozone.
At a finer level of classification are the Ecoregions. Both the Ecozones
and Ecoregions are illustrated in Map
3.
Detailed information on these ecological areas can be found in the Ecological
Classification of Manitoba’s Natural Landscapes. It provides information
on climate, biological and physical resources and other characteristics
of the land base of Manitoba. |
| Climate
of the SLRMA |
The climate of the SLRMA is
characterized by long, very cold winters and short cool summers. The mean
annual air temperature is –4.4 degrees Celcius. The average winter
temperature is -22 degrees Celcius while the average summer temperature
is 12 degrees Celcius. The average growing season varies from 130 to 160
days, too short for grain crops but suitable for a variety of grasses and
sedges in marshland areas. By comparison, temperatures 700 km south in Winnipeg
are much warmer, 2.4 degrees Celcius year round mean; about –14 degrees
Celcius in winter on average, and 17 degrees Celcius in summer.
The mean annual precipitation in the SLRMA is 494 mm (19 inches) and varies
greatly from year to year. The region has a cold, sub humid to humid climate.
The Ecozones are described in the following paragraphs. |
| The
Three Ecozones |
- The Hudson Plains Ecozone
is dominated by wetlands in the form of fens and bogs. Wetlands are
classified into subgroups: bogs; fens; marshes; swamps, and shallow
waters. Permafrost is widespread in this zone;
- The Boreal Shield Ecozone
is the largest Ecozone in Canada, extending from Newfoundland through
to Alberta. A vast blanket of closed boreal forest including many lakes
and undulating landscapes characterizes it; and
- The Taiga Shield Ecozone
is characterized by the open and stunted conifer dominated forests,
the Precambrian Shield, and the associated shallow soils and numerous
lakes.

| The
Four Ecoregions |
- The Ecoregion is the ‘finer’
subset of the Ecozone classification. The four Ecoregions in the Split
Lake Resource Management Area are described as follows:
- The Hudson Bay Lowland
Ecoregion is a wetland-dominated area extending eastward from the Churchill
River to James Bay. Vegetation consists mainly of open stands of black
spruce, with understories of dwarf birch, Labrador tea, lichen and moss.
Wildlife species include woodland caribou, moose, snowshoe hare, spruce
grouse, and a variety of waterfowl. Periodically, polar bears wander
in from the coast in search of denning sites;
- The Churchill River Upland
Ecoregion is located on the southern edge of the Precambrian Shield.
It is characterized by closed Boreal forest of jack pine, black spruce
and white spruce. The Ecoregion provides habitat for moose, woodland
caribou, black bear, lynx, wolf, beaver, muskrat, and snowshoe hare,
as well as a wintering area for barren-ground caribou. Bird species
includes cranes, grouse, eagles, owls, and waterfowl;
- The Hayes River Upland
Ecoregion is dominated by shallow peat soils and bogs, and by medium
tall closed stands of black spruce and jack pine. Wildlife includes
moose, black bear, woodland caribou, lynx, wolf, beaver, muskrat and
snowshoe hare. Bird species includes sandhill crane, spruce grouse,
willow ptarmigan, raven, Canada jay, and waterfowl; and
- The Selwyn Lake Upland
Ecoregion is part of a broad area of coniferous forest transition area
lying between the sparsely forested area in the north and the closed
boreal forest to the south. The open stands consist of low black spruce,
understories of dwarf birch, Labrador tea, lichens, and mosses. Characteristic
wildlife includes barren-ground caribou, black bear, arctic fox, snowshoe
hare, spruce grouse, and waterfowl.
