NATURAL RESOURCES IN
BRITISH COLUMBIA
INTRODUCTION
:
This unit
deals with the study of Natural Resources, case study British
Columbia in North –America. WHAT
ARE NATURAL RESOURCES? A natural
resource is anything that is provided by nature, which can be used to
satisfy human needs. A resource is anything that enables to produce
and obtain our needs. Natural resources are useful to man in very
many ways after they have been exploited. The basic needs are
shelter, food and clothing. The major natural resources of the world
are found in their natural form, which include forests, lakes,
rivers, minerals, climate, relief, and life.
This unit will
help you understand the natural resources have contributes to
economic and development of British Columbia. You will be able to
compare the extent to which natural resources in their own region
have been exploited for development in relation to those found in
British Columbia. In this unit you learn about how fishing and
forestry have contributed to development and compare with the natural
resources utilisation on East Africa.
You will also
learn about various methods and strategies how these natural
resources have been effectively exploited. You will be able to
appreciate that some countries have succeeded/developed or failed to
develop in many fundamental ways simply because they have been able
or unable to process and add value their natural resources.
FISHING
Fishing is the second
leaching activity in British Columbia. This provides 60% of fish in
Canada. This fishing industry depends on the direct exploration of
natural resource hence a primary sector.
British Columbia is a
province with endowed areas of great concentrate of fish, these
include;
- Pelagic fish – which live and breed close to the surface of the sea like Tuna and Mackerel.
- Dermal Sal fish – which line is close to the bottom of the sea such as cod, halibut and hadlock..
- Anachroman, which live in the ocean but breed from fresh waters like salmon.
- Crustaceous fish. Such as, lobsters, shrumps, crabs, oysters and prawns.
The major fishing grounds of
British Columbia, along the coast where deep fishing is practical
other fishing grounds include Lakes/ Rivers and man made ponds
- Fishing in B.C is a better alternative apart from forestry since the souls are infertile for agriculture and the climatic conditions are too harsh, limiting the population on the coastal areas.
- Improved technology is another factor. This is reflected in developed fish methods which include; the use of drifters, trenkers,etc and also improved preservation methods use of refrigerators and canning. In addition to the cool climate in the region offers natural preservation.
- Presence of skill and manpower who give specialized work in the different areas e.g. fishing, preserving and canning.
- Presence of capital for the development of the sector. This is mostly needed in purchasing of up to date fishing gear.
- Presence of market for fish. Most of the natives depend on fish for proteins. There is ready market at home and abroad especially U.S.A and North America.
Water Resources
This unit deals with water as
one of the natural resources of British Columbia and fishing is one
of the major economic activities.
By the end of the lesson
students should be able to;
- Identify the fishing grounds in British Columbia.
- Identify the types of fish species in the waters of British Columbia.
- Describe the methods of fishing used, preservation methods
- Explain the factors favouring fishing in British Columbia.
- Explain or identify the problems facing fishing in British Columbia and their solutiError: Reference source not found
- Texts
- Pictures of different species of fish e.g. salmon, crab, oysters etc.
Error: Reference source not foundFactors
favoring fishing in British Columbia
- The presence of the water bodies both fresh (the lakes, rivers and ponds) and the salty ocean waters (marine fishing), this leads to a variety of fish in the area.
- The good climatic conditions created by the ocean currents (the warm North pacific eluft and the cold Alaska current). These lead to the upwelling of cold water a long the coast thus bringing plankton food for the fish to the surface thus extracting the fish in great members.
- Good hobours - The North American coast around the British Columbia is an identified coastline, which offers the province safe sheltered hobours for good landing grounds, for development of ports and fish landing sites.
- The waters are deep enough along the coast making deep-water fishing possible.
METHODS OF
FISHING
Purse-seining method
It’s practiced deep waters,
involves use of two boats, large and small nets supported by weights
and floats. The net is connected on a small boat, which pulls it
around a shoal of fish. The fish is then pulled into the big boats
and transported to the shore.
Trawling method
This is mainly used in
catching the demersal fish and it involves dragging a cone bag made
of nets ( a trawl) over a sea bed. The trawl is attached to the boat,
which drags it on the shore through the water to catch the bottom or
dermesal fish.
Drifters (or Gill) net methods
The holes of the net are big
enough to allow the fish enter in their effort to treat, they are
caught by the gill
Trapping
These are commonly used for
the crustaceous fish species e.g. lobsters, crabs. A trap box is set
with baits inside. It is fastened on the boat with a rope then in the
sea and want for catch.
PRESERVATION METHODS
Canning: mainly used
for the fish, which is to be exported.
Salting: is a method that
dehydrates the fish hence preserving it. It also protects fish from
bacterial attacks. Salted fish is usually for export.
Refrigeration and
refrigeneted trucks used on fish to be consumed fresh.
Smoking is another
traditional method that is usually used and it is facilitated by
presence of wood. It’s mainly for home market.
PROBLEMS FACING FISHING IN
BRITISH COLUMBIA
- Over fishing. There is a danger of wiping out some of the species due to indiscriminant fishing. This is mainly affecting the salmon fish, usually caught when migrating for breeding.
- Pollution of the coastal water from the industrial areas.
- Construction of dams across the rivers and the floating logs abstract the movement of fish when migrating to their breeding grounds.
- Limited home market due to low population.
- Shortage of labour due to the small population and the fact that most people are encouraged in the forestry industry
- There is competition from other fish-producing region, like Japan.
- Price fluctuation of fish.
SOLUTIONS TO FISHING
PROBLEMS IN BRITISH COLUMBIA
Over fishing
- Establish laws against over fish
- Ban fishing in the breeding season.
Pollution
- Treatment of the waste before dumping.
Obstruction from dams
- Numbers of dams along the rivers are being reduced.
Obstruction from logs –
- Some rivers not used to transport logs
Carry out research to acquire
a wider market.
Set up factories that use
fish as a raw material.

7. Temperate forests
(coniferous) type
- Characteristics include:
- They grew in pure stands since few species can survive the harsh conditions.
- Their leaves are thin and needle shaped with hard skin so that they drop off the snow easily in severe winters.
- The branches are downward facing , making the trees cone-shaped all for quick snow slide off.
- The fruit peel is hard to protect the seed from freezing before maturity.
- The trees grow up very fast –a factor facilitating easy afforestation and re-afforestation.
- They have soft wood tree species i.e. harch, larch, spruce, pime, etc.
-
- the most popular tree species include:
- the Douglas fir
- Balsam fir
- The red Cedar
- Spruce
- Western Hemlock coak
Tropical forests are forests
that are adaptable to tropical climate conditions i.e. hot and wet.
These forests consist of hard wood species.

TEACHING/LEARNING
MATERIALS
Useful Notes for the
Teacher (introduction)
- The economy of British Columbia: Resources from Natural Vegetation
The economy of British
Columbia is based on the province’s great natural resources,
primarily its vast forests, which cover 56 percent of its total area;
conifers from these forests are converted into timber, newsprint,
plywood, pulp and paper products. These make lumbering an important
activity followed by tourism, fishing, mining and power generation.
Other sectors such as agriculture and manufacturing are secondary
importance
The most popular tree
species include
- The Douglas fir
- The Balsam fir
- The red cedar
- The spruce
- The western Hemlock oak.
British Columbia’s
vegetation is dominated by forests, which are mainly of coniferous
type. These are well adapted to their climatic conditions for
example;
- They grow in pure stand since few species can survive the harsh climatic conditions.
- Their leaves are thin and needle shaped with hard skin so that they drop off the snow easily in winters.
- The branches are downward facing making the tree cone-shaped all for quick snow slide off.
- The fruit peel is very hard to protect the seed from freezing before maturity.
- The trees growing up very fast a factor facilitating easy forestations and re-forestation.
- They have softwood tree species.
Their timber however, is
less durable that of deciduous and tropical forests (durability)
decreases with increasing hatituclinal extent, thus less expensive
Lumbering is a
very important economic activity in British Columbia, with very many
wood products. It has led to many related sub-sectors for example
industries like the paper, timber, pulp, wood; plywood etc. about 40%
of Canada’s exports consists of wood products. The main wood
product-manufacturing centre is part Alberni on Vancouver Island.
Reference: M Yiga Matovu
(1984) North America, London, Oxford University Press
- Factors favouring the development of forestry in British Columbia
- There are many good commercial types of trees, which grow in pure stands.
- There is heavy rainfall all year round allowing the forests to grow.
- The barren Rocky Mountains do not favour other types of land use.
- The climate of warm summers and mild winters is favorable for the growth of coniferous forests.
- The steep mountain slopes have thin soils which can best be used for forestry.
- The fiords make transpiration of logs easy.
- The government policy, carefully conserves the forests.
- Sawmills or factories are available at the coast to process out the wood or timber etc.
The process of
lumbering
Lumbering is done in
stages. Namely;
- FELLING. It is the cutting down of a tree done by men called fallers. They work in pairs and wear brightly coloured helmets to help tem check each others position before a tree is cut down.
- BUCKING: it is the cutting of logs into shorter pieces that are 12-15 meters long. This is because the trees are usually very tall.
- YARDING/DRAGGING. A machine known as mobile steel spur with long cables is used by the choker men to drag the logs into a safer place and load them on trucks.
- LOADING: This is the process whereby the logs are loaded on to trucks.
- BARGING: This is the process by which logs from far away are brought to the booming ground (central place where logs are collected) by boats called self dumping barges. These are flat bottom boats pulled by a tug (small boats)
To
unload the logs, the valves are open on one side of the barge, water
rusles up the tanks on the side then the boat tilts over and spills
the logs into the water. After the water is drained the barges rises
itself again.
- A BOOMING GROUND: it is a central place where the logs are sorted out according to size, quality and species. Port Alberni has a large booming ground. The Douglas fur logs go to the plywood factory, western Hemlock and Balsam fur to the sawmills.
- Problems facing lumbering in British Columbia and their solutions
- Winter freeing: Rivers are frozen from December to February making the saw mills produce at an under capacity because the logs cannot be moved to the mills fro processing. This is further worsened by the long distances from the forests to the sawmills, which are mainly at the coast.
To over
come this, lumbering is practiced in phases. The system of log high
and low was started. The areas of high altitude are logged in summer
(log high) when there is no snow while those at low altitude can be
logged in winter where the roads are opened by snow ploughs.
- Summer fires; These are mainly caused by the holidaymakers who go camping in the interior of the forests.
To over
come this, fire guards from established control towers serve the
purpose. Air patrols by helicopters is also another solution. Water
stations are also distributed in the forests such that the patrolling
crews get access water when putting out fire
- Deforestation: This has reduced the tree species some of them are now disappearing away (becoming extinct) the solutions to this includes re-a forestation and a forestation. The harsh climatic conditions, however, do threaten these activities since the replanted trees have to take long periods to mature because of the dormancy in growth during the winter season.
- Topography. This makes transportation of logs difficult especially in the interior of the forest where the roads are sometimes slippery. High gear vehicles are used.
- Over exploitation of the accessible areas. Systematic and selective felling of trees is carried out.
- Diseases and fungal. Infection attacks the trees because of the acidic rain and extreme coldness. Spraying is done using helicopters.
- Labour shortage is a common problem since the permanent workers in the forests are few. The wages for these workers are often revised to attract them.
- Accidents, snakebites and other harmful jungle animals sometimes do harm the workers’ use of chemicals to chase them, heavy equipment like burgers, gumboots and helmets as well as working in pairs are among the solutions.
- Thickness of the forest. This makes penetration into the interior where good quality trees may be found difficult. The solution to this is to encourage spacing during aforestation and reafforestation. There is also need to construct more roads and railway lines from the booming grounds to the central collecting points are also from the latter to the interior of the forest.
- Long jams, which occur in the rivers when the logs get stuck during floatation. These are sorted out using a boom scouter. Etc
