British Columbia Flora and Fauna
Sitka Spruce
The Sitka spruce is the largest spruce tree in British Columbia and is found along the west coast of the province and Vancouver Island. It usually grows between sea level and 700 metres. Sitka spruce reach an average of 70 metres tall and two metres in diameter. Some trees have grown up to 93 metres tall and five metres in diameter.
Sitka seed cones are reddish to yellowish-brown and have wavy, papery scales with ragged edges. The pollen cones are red. Sitka spruce needles are the longest and flattest leaves of British Columbia’s spruce trees. They are four-sided, bluish-green, stiff and sharp and are arranged spirally along the tree’s branches. Each needle has a white line on both the upper and lower surfaces. The Sitka’s bark is brown or purplish-grey, thin and scaly.
The wood is light, soft, strong and flexible. Sitka spruce were considered by some native tribes to have magic powers. Natives used its roots to make hats, baskets, ropes, fishing lines and twine; its inner bark as a source of vitamin C and as a laxative; and its pitch to caulk and waterproof boats, harpoons and fishing gear, and as glue and medicine for burns, boils and other skin irritations. They also carved its wood into love charms. Today, it is used in general construction, ship building, plywood, musical instruments and airplane construction.
Western Red Cedar
The western red cedar is British Columbia’s official tree. It is found at low to medium elevations in cool, mild, moist locations. It typically grows in shaded areas with lots of nutrients and reaches heights of up to 60 metres tall. The western red cedar is characterized by drooping branches that turn up at their tips, a trunk that spreads out at the base and a large number of cones bent backward along the branches.
The seed cones are egg shaped and one centimetre long with several pairs of scales. The pollen cones are small and reddish coloured. The needles, or leaves, are scale-like and lie in pairs, overlapping like shingles; they have a very strong aroma. The bark is grey and stringy, tearing off in long strips. The wood is resistant to decay and insect damage and often remains sound for over 100 years. Traditionally, the First Nations people used the wood for canoes, totem poles, longhouses, household boxes, tools and paddles. They pounded fibres to make mats, clothing, baskets, nets, fishing lines, medicines and religious masks. Today, western red cedar is used for house siding, interior panelling, outdoor furniture, decking, fencing and roof shakes.
Douglas Fir
The Douglas fir is named after Scottish botanist David Douglas, who introduced many of British Columbia’s native conifers to Europe. It is found on the southern mainland coast of British Columbia and Vancouver Island. An interior variety is found throughout southern and central British Columbia. A Douglas fir can reach up to 85 metres in height. It is distinctive for its three-forked bracts between the cone scales. The cones are five to 11 centimetres long, green when young, turning to brown as they age.
The winged seeds are eaten by birds and small animals. The needles are flat with pointed tips; they are bright yellowish-green with a single groove on the upper surface and a paler colour on the lower surface. The needles are spirally arranged and appear to stand out around the branch; they are fragrant and soft to the touch. The bark is smooth, grey-brown and blistered when young. Furrowed, thick, dark reddish-brown ridges appear as the tree ages.
