The whole Georgia Depression ecoprovince is in the small area of southeastern Vancouver Island, the Gulf Islands, and the Lower Mainland. It includes the territories many First Nations including Semiahmoo, Tsleil-Waututh, Musqueam, Tsawwassen, T’Sou-ke, Esquimalt, Songhees, Saanich, Coquitlam.
Most of this area is in a rainshadow because it is sheltered from rain by the mountains on Vancouver Island and the mountains on the Olympic Peninsula in Washington. This means the region gets less rain than areas outside the rainshadow (especially compared to the Coast and Mountains ecoprovince). The climate is not too hot in the summer and not too cold in the winter.
Much of the area is dry, flat and low elevation,and has unique plant and animal habitats. This ecoprovince is the only place in B.C. where Garry Oak trees and meadows can be found. It is also where coastal Douglas fir forests, and the many plants and animals that only live in these forests, are found.
A proposed pipeline carrying diluted bitumen from Alberta would run through the Strait of Georgia, at the heart of the Georgia Depression ecoprovince, and put at risk the habitat of many species like the orca whale and the Dall’s porpoise.
The major cities are Vancouver, Victoria, Nanaimo and Powell River.
