It should be noted however that compiling two years of lake testing data limits any long-term,
interpretations in lake quality. Short-term testing (2-3 yrs) data can easily become distorted by
different wet and dry seasons, water levels, or weather variations. A minimum testing period of 8-10
years with four or more per season is recommended by the Minnesota Pollution Control Agency
(MPCA) to evaluate long term lake health. TNC staff in conjunction with the Environmental office
will continue to monitor water quality at Sylvan-Main and Sylvan-North to further assess lake health
in the future.
WILDLIFE
Species in Greatest Conservation Need
Species in greatest conservation need (SGCN) are defined as native animals whose
populations are rare, declining, or vulnerable to decline and are below levels desirable to ensure their
long-term health and stability. One of the federal requirements of the Comprehensive Wildlife
Conservation Strategy to manage species in greatest conservation need was that all states and
territories develop a wildlife action plan by October 2005. “Tomorrow's Habitat for the Wild and
Rare” is Minnesota‟s response to this congressional mandate. It provides direction and focus for
sustaining SGCN into the future (MNDNR 2006).
In Minnesota, 292 species meet the definition of species in greatest conservation need. All
listed species (federal and state) are included on SGCN list. This set of SGCN includes mammals,
birds, reptiles, amphibians, fish, insects, and mollusks, and represents about one-quarter of the nearly
