British Columbia’s Coastal Mountains are a prominent mountain range along Canada’s Pacific Coast. They feature diverse geology and ecosystems that support a variety of plant and animal species. Understanding these natural features provides insight into the region’s environmental importance.
Geology of the Coastal Mountains
The Coastal Mountains are primarily composed of granite and metamorphic rocks formed over millions of years. Tectonic activity, including the collision of the Pacific and North American plates, has shaped the range. Glacial processes have also carved deep fjords and valleys, creating dramatic landscapes.
Major Ecosystems
The region hosts several ecosystems, including temperate rainforests, alpine zones, and coastal wetlands. These ecosystems support a wide array of flora and fauna, many of which are adapted to the specific climatic conditions of each zone.
Key Species and Habitats
- Spirit Bear: a rare subspecies of the black bear found in coastal rainforests.
- Salmon: vital for the ecosystem, spawning in rivers and supporting predators like bears and eagles.
- Old-growth forests: home to diverse plant species and important for carbon storage.
- Mountain goats: adapted to steep, rocky terrains in alpine zones.
