Basics

The details of this Sample Design, including all the parameters used to generate it, are included below. Sample designs must belong to a Study Plan.

Description

Started with the WA DNR master sample, and then refined the frame to only Municipal Watersheds in King County and streams of Strahler Order 0, 1, or 2. I then stratified based on Ecoregion and Strahler Order to ensure I got a spread of sites in the Puget Lowlands as well as in the Cascades.

Master Sample

This sample design is based on master sample: Washington Statewide Master Sample

Details of this master sample:



Frame Definition

Frame

This sample design started with an initial frame of 387,237 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 1,337 sites:

Criteria Group 1
           
  County Is Equal To King County AND
  Land Management Type Is Equal To Municipal Watershed
AND

Criteria Group 2
           
  Strahler Order Is Equal To 0 OR
  Strahler Order Is Equal To 1 OR
  Strahler Order Is Equal To 2

Target Population

<none>


Panels

Panel designs can help address sampling objectives by increasing the total number of samples at a lower overall cost. A common panel structure involves one or more panels with a high revisit frequency (e.g. an “Annual” panel), and other panels with a lower revisit frequency (e.g. a three year “Rotating” panel).

Stratification

This design uses the following attributes to create the stratification shown below. Each row in the table represents a stratum. This design’s panels are also shown in the table, even if it uses only a single, default panel.
