Cook Inlet taiga

Cook Inlet taiga

The Cook Inlet taiga ecoregion, in the Taiga and Boreal forests Biome, is located in Alaska.

Contents

Setting

This ecoregion is located around the upper Cook Inlet on the south-central coast of Alaska, sheltered by mountains on all sides. This coast has a gentle landscape and a relatively mild climate for Alaska with 380–680&nbsp:mm of rainfall per year.[1]

Flora

The plant life here is varied for Alaska, a mixture of conifers and other trees, shrubs and herbs, with the dominant trees being black spruce (Picea mariana), white spruce (Picea glauca), the large Sitka spruce (Picea sitchensis), quaking aspen (Populus tremuloides), balsam poplar (Populus balsamifera), black cottonwood (Populus trichocarpa) and paper birch (Betula papyrifera). The spruce forest is regularly renewed following severe damage by spruce bark beetle infestations.

Fauna

This area is rich in wildlife including Grey Wolf, bears and Canada Lynx. The Kenai River is home to five species of Pacific salmon including the largest Chinook salmon in the world. Birds include large numbers of Bald Eagle and wintering Snow Goose from Wrangell Island who gather in the mouth of the Kenai River before their srping migration.

Threats and preservation

The Kenai River, Anchorage, Palmer and Wasilla areas are the most populated part of Alaska and a base for logging and the oil and gas industries on the Kenai Peninsula. There is also some clearance for farming in Palmer and Point MacKenzie. Nonetheless natural habitats remain very well preserved although wildlife of the Kenai Peninsula has become isolated from that of the Matanuska-Susitna Valley and the west side of Cook Inlet, and therefore from the rest of Alaska. Protected areas include Kenai National Wildlife Refuge, Chugach State Park, Nancy Lake State Recreation Area and the Susitna Flats.
