NCCN Monitoring Mountain Lakes

Fradkin S, Lofgren R, Anthony H. NCCN Monitoring Mountain Lakes. 2005. National Park Service

Determine the status and detect substantive trends in key ecosystem parameters to assess whether mountain lakes are being negatively affected by anthropogenic stressors. The selected Vital Signs represent physical, chemical, and biological components of lake ecosystems that characterize the quality and natural function of these ecosystems. Purpose: Determine the status and detect substantive trends in key ecosystem parameters, or vital signs, to assess whether mountain lakes are being negatively affected by anthropogenic stressors. The selected Vital Signs represent physical, chemical, and biological components of lake ecosystems that characterize the quality and/or natural function of these ecosystems. These data represent results from field observations of 20 high forest/subalpine lakes, six in MORA and NOCA, and eight lakes in OLYM. Each year, each of these 20 lakes are visited once during the late-summer and early fall period (August through September). The Vital Signs of NCCN Mountain Lakes are grouped into three main categories of parameters: Physical, Chemical, and Biological. The Physical Parameters consist of the following data: Continuous water temperature, Continuous air temperature, Temperature profile, Lake water level, Depth, Volume, Surface area, Littoral zone substrate, Riparian cover and disturbance, and Water clarity (Secchi disk depth). The Chemical Parameters consist of the following data: Dissolved Oxygen, pH, Specific conductivity, Acid neutralizing capacity (ANC), Nutrients, Total dissolved solids (TDS), Anions and Cations, and Dissolved organic carbon (DOC). The Biological Parameters consist of the following data: Chlorophyll a, Zooplankton, Littoral benthic macroinvertebrates, Amphibians, and Fish.
