Description du site
Comox Valley IBA, Baynes Sound IBA and Lambert Channel/Hornby Island Waters IBA share common populations of waterbirds but were established as separate IBAs because they were nominated independently. In 2013, these sites were amalgamated into the K'omoks IBA; follow this link for current information for this area.The Comox Valley lies along the east-central coast of Vancouver Island, near the town of Courtenay. The site is bounded to the north by the Oyster River, to the south by the Trent River and Comox Harbour, to the west by the Beaufort Mountains, and to the east by the Strait of Georgia. The estuaries, backshore areas and associated lowland valley bottoms provide an extensive network of habitats. Inland valley lowlands are a mixture of agricultural areas and forested land. Low elevation forests are dominated by Douglas Fir and Western Hemlock forests. Within the valley are three urban centres, as well as a 10,000 hectare estuary. The valley has a relatively mild climate, with winter temperatures above freezing point, but generally less than 10°C on average.
