Abandoned Mineral Lands in the National Park System: Comprehensive Inventory and Assessment.

摘要

This Abandoned Mineral Lands (AML) inventory and assessment report presents the results of a four-year coordinated effort by the National Park Service (NPS) Washington Office, Natural Resources Stewardship and Science Directorate, Geologic Resources Division; NPS Abandoned Mineral Lands Advisory Committee (AMLAC); NPS Denver Service Center; and 133 parks known to have AML sites within their boundaries. This project had two primary objectives: Complete a comprehensive inventory of AML sites in units of the National Park System that categorizes high, medium, and low priority mitigation needs; and Estimate the resources needed to address priority mitigation needs at NPS AML features using a consistent, credible approach.
