This sample design is based on master sample: Lower Columbia
Details of this master sample:
- Source: ESA Sitka
- # of sites: 141653
- Type: Linear Master Sample
Frame
This sample design started with an initial frame of 141,653 sites, based on its master sample. The criteria (based on the master sample's attributes) were then used to refine the sample frame down to 5,202 sites:
Target Population
