Jewel Cave National Monument Natural Resource Condition Assessment.

摘要

Jewel Cave National Monument (JECA) was established by Theodore Roosevelt in 1908. The 515-ha (1,274-ac) JECA was established to protect the Jewel Cave ecosystem and its unique geologic features for scientific study and public enjoyment. More than 100,000 people visit JECA each year to participate in cave tours and to hike trails in JECA. As a unit in the National Park System, JECA is responsible for the management and conservation of its natural resources. This mandate is supported by the National Park Service Organic Act of 1916, which directs the Park Service to 'conserve the scenery and natural and historic objects and the wildlife therein and to provide for the enjoyment of the same in such a manner and by such means as will leave them unimpaired for the enjoyment of future generations.'
