Natural Features & Ecosystems
The Alaska Coastal Temperate Rainforest is home to a complex web of ecological interactions that allows the organisms within it to thrive. Each participates in a web of life and death that keep the surrounding landscape healthy year after year.
Certain species in an ecosystem drive interactions between ocean, river, and land. Just as an arch would collapse with out the keystone, ecological communities, too, would fail without these all-important animals.
Glaciation, deglaciation, volcanic activity, and tidal erosion all shaped Sitka's changing shoreline and landforms. Digging into the soil, geologists can tell how the landscape has changed over the millennia.
Intertidal and Subtidal Zones
The intertidal zone and estuarine areas comprise nearly half (44%) of the park's total acreage. Water-bird feeding, salmon migration, and provision of essential clam bed habitat are just a few of the important functions of the park's intertidal zone.
