The system of biogeoclimatic ecosystem classification was partly created for the purpose of managing forestry resources, but is also in use by the British Columbia Ministry of Environment and Climate Change Strategy and other provincial agencies. A biogeoclimatic zone is defined as "a geographic area having similar patterns of energy flow ...
Biogeoclimatic ecosystem classification (BEC) [1] [2] is an ecological classification framework used in British Columbia to define, describe, and map ecosystem-based units at various scales, from broad, ecologically-based climatic regions down to local ecosystems or sites.
The dense and diverse forests make this zone the second most productive forest zone in British Columbia and Canada. Sub-Boreal ( Hemiboreal ) Spruce and Pine-Spruce Zones: The central interior of the province, consisting of the rolling lake-studded terrain of the Cariboo — the Fraser and Nechako Plateaus — is characterised by severe, snowy ...
The coast of California north of San Francisco contains the Northern California coastal forests (as defined by the WWF) and the southern section of the Coast Range ecoregion (as defined by the EPA). This ecoregion is dominated by redwood forest , containing the tallest and some of the oldest trees in the world.
The most California tornadoes on a single day in the state was seven, which occurred on November 9, 1982. [58] In July 2004, a twister touched down in Sequoia National Park at an altitude of around 12,156 ft (3,705 m), making it the highest elevation for a confirmed tornado in the United States.

The differences in climate from south to north create several major forest zones, characterized by different species. At the southern limit in northern California is the "coast redwood zone". Beginning at the California/Oregon border, and extending through the north end of Vancouver Island is the "seasonal rain forest zone".
The Vaseux-Bighorn National Wildlife Area extends over the Bunchgrass and Ponderosa Pine Biogeoclimatic Zones of British Columbia. [4] Both biogeoclimatic zones fall in the Coast and Purcell mountains' rain shadow, creating a dry climate in the Vaseux-Bighorn NWA with hot summers and relatively short winters. [4]
