Land Cover and Development
Conversion of ecologically important lands
This indicator tracks the fate of ecologically important lands under development pressure in Puget Sound watersheds. The measure is the percent of vegetated cover on undeveloped lands identified as both ecologically important and under high pressure from development that is converted in a given time period to developed cover. The rate of conversion of vegetated cover is estimated using Landsat satellite imagery with a 30-meter resolution.

Key Indicator Results

  • The status of this indicator has improved relative to the baseline rate of land cover change and is making progress toward the 2020 target.
  • The five-year baseline rate of land cover change on the indicator land base across all 12 counties in Puget Sound was 0.28 percent for the period 2001-2006.
  • The rate of land cover change increased to 0.36 percent over the period of 2006-2011 and then dropped to 0.18 percent during the 2011-2016 period.

Recovery Target

Basin-wide loss of vegetation cover on ecologically important lands under high pressure from development does not exceed 0.15 percent of the total 2011 baseline land area over a five-year period.
