Reports from the Sauk-Suiattle Tribe’s amphibian surveys are available on the Encyclopedia of Puget Sound website.
The surveys began in 2007 with support from the Environmental Protection Agency, and are conducted weekly from late February to late May near the Sauk River. Their aim is to assess changes in amphibian populations, as well as water and habitat quality.
The 5.5-acre survey area is ranked as a Category I wetland, defined by the Department of Ecology as wetlands that are a unique or rare type, are more sensitive to disturbance, contain ecological attributes that are irreplaceable, or provide a high level of functions.
