Changes Within Habitats
Within a few steps is the transition from a dry meadow into a cooler forest of Douglas-fir, spruce, and common juniper. The moisture content is higher here. Though you're looking south, you are standing on a north-facing slope. North-facing slopes receive less sunlight throughout the year than south-facing slopes. This results in differences in plant and animal communities.

The Fossil Record
Fossil evidence shows that there were microhabitats within the ancient ecosystem that existed here 34 million years ago. Cattails lived in or near water. Redwood trees likely grew in groves along the valley bottoms. Shrubby species of oak and mountain mahogany probably grew on higher and drier slopes and ridges. The highest elevations in the surrounding mountains were inhabited by fir, spruce, pine, and hemlock.
