The Ecological Types of Mount Shasta is a summary of a Terrestrial Ecologic Unit Inventory that was conducted by the U.S. Forest Service. The intent of the inventory was to study the geologic processes and landforms of the area and relate them to the soils found on the mountain. The soils mapped were used to model vegetation patterns. The three elements are integrated into a single ecological concept. The scale of mapping used in the section is termed Land Type Association and it meant to be a broad and general description. This scale of mapping is meant to describe general concepts and it is not meant to be used for site-specific purposes. Mapping standards were set by the National Hierarchy of Ecological Units (U.S. Forest Service, Natural Resources Conservation Service 1997). More specific mapping was done as part of the inventory and is available from the Forest Service in Mount Shasta. Please note that terms written in SMALL CAPS are linked to definitions in the glossary.
