Sierra Nevada Network Lake Monitoring
Sierra Nevada Inventory and Monitoring Network, Martin K, Fong C. Sierra Nevada Network Lake Monitoring. 2008. National Park Service
The Sierra Nevada Network (SIEN) monitors high-elevation lakes throughout Sequoia, Kings Canyon, and Yosemite National Parks as part of the National Park Service’s Inventory and Monitoring (I&M) Program. The purpose of the I&M Program is to develop and provide scientifically sound information on the current status and long-term trends in the composition, structure, and function of park ecosystems, and to determine how well current management practices are sustaining those ecosystems. This is accomplished through park-wide inventories and a long-term monitoring program. Sierra Nevada Network parks protect over 4,500 lakes and ponds and thousands of kilometers of rivers and streams that have some of the highest water quality in the Sierra Nevada. High-elevation lakes are critical components of the parks’ ecosystems, popular visitor destinations, and habitat for aquatic and terrestrial organisms including declining amphibian species. Lake ecosystems were selected for monitoring because they are 1) valued for their ecological importance, contribution to Wilderness character, recreational opportunities, and importance to regional water supplies, 2) threatened by multiple stressors, and 3) sensitive to environmental change. Three vital signs (i.e. ecological indicators) are sampled at SIEN lakes: water chemistry, surface water dynamics, and amphibians.
