Boreal Forest around Central British Columbia Canada (Prince George)
Boreal forest is a large area of the biome that is located in most of the northern area of
North America and extends across a large part of central British Columbia where Prince
George is situated. The climate of this sub-boreal area is continental with long winters and
short summer, the average temperature of the coldest month is between -12 and -18°C and
the average temperature of the warmest month is between 15 and 20°C. The ecosystem
services of the boreal forest and the plant and animal species that inhabit the region are
described as being unique to the particular biome due to the severe climatic conditions that
prevail in the area.
Climate and Soils
With regard to climate, the boreal forest surrounding Prince George, British
Columbia, maintains a continental climate that sees large differences in temperature
throughout the numerous seasons. The climate can be quite moderate with low temperatures
ranging -10 °C in January and high temperatures being about 15 °C in July (Griesbauer et al.,
2021). The humidity level is moderate in this area receiving between 400 and 800 mm of rain
per year, with much of this occurring in the form of snow in winter. An important aspect of
the climate is that it is continental, which means that winter is long and cold while summer is
relatively short and warm; these conditions affect the geography and especially the vegetation
that is able to grow in this climate.
The typical soil types found in the Prince George area are podzols, which involve a
thin dark colored organic layer over a pale colored, leached, acidic mineral layer. This type of
soil is generally located in the boreal forests and it is created where there is heavy rainfall and
low temperatures which causes washing of nutrient ions (Griesbauer et al., 2021). Lack of
permafrost in this southern part of the boreal forest biogeographical province generate better
soil formation and moisture which are so important for an assortment of tree species
3
including hybrid white spruce and subalpine fir. The climate factors such as the soil moisture
regime play a significant role in determining forest yield and nature of species establishment
since water is an important resource for tree growth and to enable it to withstand climate
variation.
Plant Communities
The study area in Prince George, British Columbia, is covered by the boreal forest
that consists of coniferous trees adapted to the climate and podzolic soils. The climax
vegetation in this ecosystem is the hybrid white spruce (Picea glauca (Moensch) Voss x Picea
engelmannii Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.), which are often found
together in mid- to late-seral habitats from diverse elevations and microsites in the region
(Griesbauer et al., 2021). Some of other economical trees found in the boreal are lodgepole
pine (Pinus contorta), trembling aspen (Populus tremuloides), and paper birch (Betula
papyrifera). The subcanopy layers include ericaceous shrubs like the Labrador tea
(Rhododendron groenlandicum), blueberries (Vaccinium spp.), the crowberries (Empetrum
nigrum), feathermosses (Pleurozium schreberi, Hylocomium splendens). Wildfire is a natural
process that influence the structure of the forest, and species like the lodgepole pine which
are fire-regenerate species can grow back quickly when fire has passed through the area.
Animal Communities
The region of Prince George and the surrounding boreal forests are productive and
dynamic habitat for a wide range of species. The large wild life animals include moose (Alces
alces) that easily spotted feeding on vegetation in the ‘taiga’ type of forests and marshes
(McNay et al., 2022). The other large mammalian inhabitants of these forests include the
woodland caribou (Rangifer tarandus caribou), which are native to the region but face the risk
of extinction due to factors such as habitat loss and predation. The two species of bears found
in this area are the Grizzly Bear (Ursus arctos) and the Black Bear (Ursus americanus), and
4
the grizzlies mainly inhabit the remote regions (McNay et al., 2022). The grey wolves (Canis
lupus) are essential components of the ecosystem that act as the apex predators or the
carnivores that feed on the large herbivores. These big predators and their prey have a
number of dynamics that are integral for the overall operations of the boreal forest system.
Apart from the large mammal species, there are many smaller mammals and birds that
inhabit the boreal forest territory in and around Prince George. The snowshoe hare (Lepus
americanus) is another mammal that is regularly seen here especially in areas with thickets as
they feed on them while hiding from predators (McNay et al., 2022). Red squirrels
(Tamiasciurus hudsonicus) are often seen and heard in the tree tops chattering, while the
secretive Canada lynx (Lynx canadensis) stalks the forest in search of its prey. Birds
including the spruce grouse (Falcipennis Canadensis), the boreal chickadee (Poecile
hudsonicus) and other birds such as the varied thrush (Ixoreus naevius) are found in this zone
and may be heard singing melodiously. The wet conditions within the wetlands as well as the
moist forest floors are suitable for the frogs such as the wood frogs (Lithobates sylvaticus)
and the boreal chorus frogs (Pseudacris maculata) making the area more unique in terms of
its ecology (McNay et al., 2022). All these species, and many more, create a rich and
complex ecosystem; each species has its own roles and contribution towards the stability of
the boreal forest around Prince George.
Ecosystem Processes
The boreal forest is indeed an ecosystem that is shaped largely by disturbance
regimes, namely, wildfires, and insects. The rate of nutrient cycling is also slow owing to the
cold climate and the fact that the soil in the region is acidic. Beavers (Castor Canadensis) are
noted for being ecosystem engineers that enhance the creation of wetlands hence diversifying
the habitat (McNay et al., 2022). Other example includes salmon (Oncorhynchus spp.) which
5
are migratory species that connect aquatic and terrestrial habitats and transport nutrients from
coastal marine environment to inland habitats.
Human Impacts
The following are some effects of human activities on the boreal forest around Prince
George British Columbia. Deforestation due to logging, mining, and the expansion of human
settlements has resulted in the loss of a net of one million hectares of tree cover in the region
from 2000 to 2020 (Fuentes et al., 2020). Other hazard risks include global warming and
climate change, which are characterized by high temperatures, alteration of precipitation
regimes, increased incidence of fire disasters, and pest and diseases like the mountain pine
beetle that affected millions of hectares of pine forest in central British Columbia in the early
2000s. These environmental changes are thus detrimental to the health and welfare of
Indigenous peoples as they limit access to ecosystem goods, limit the passing on of
indigenous knowledge and impact on lifestyle.
Some protection measures in the boreal forest around Prince George include the
designation of conservation areas, support of rational forest practices, and the adoption of the
legislation such as the Zero Net Deforestation Act (Fuentes et al., 2020). However,
sustainable use of resources for development and conservation of ecosystems still persists,
and tackling climate change effects and maintaining the natural structure of this vital biome
continue to be a challenge. These effects are considerably more profound among Indigenous
peoples; however, increasing their personal resources and community assets may decrease or
counteract these consequences and mitigate the support from family and friends.
In conclusion, the boreal forest around Prince George is a diverse and active biome
with influences natural disturbance processes as well as anthropogenic disturbances. This
being a sub-boreal region offers numerous resources and ecosystem services but is also
vulnerable to the impacts of climate change, deforestation, and industrialization. Various
6
managerial strategies that will ensure that ecological, economic and social factors are
optimally met will be key in the sustenance of this biome.
