Publisher's Synopsis
Excerpt from Inventory of the Aquatic Resources in the East and North Forks of the Virgin River in and Above Zion National Park, Utah
In order to preserve and protect natural resources within the National Park System, it is important to understand the underlying ecological factors controlling and maintaining critical resource attributes of the system. The factors governing the ecological components of stream systems are highly variable. In general, the structure and function of ecological communities in arid streams is a function of the nature and strength of those factors. Inventories of natural resources addressing management concerns for preserving natural systems should include analysis of the status of these factors. Preservation of the environmental conditions is critical to sustaining the natural condition of aquatic resources.
