Stratification Example

Example Step 6: Apply stratification and select statistically valid monitoring locationsStep4_AIM

Terrestrial

Monitoring locations were selected using the terrestrial master sample tool (Fig. 1).  This tool relies on the GRTS method which produces random, spatially balanced points across the landscape of interest (Stevens and Olsen 2004).  Points were reviewed to make sure that they met the design criteria described in steps 1-3.

Aquatic

In total 24 sample reaches were selected for potential sampling (i.e., base reaches) and over double that number as potential replacement reaches for failed reaches (i.e., oversample reaches = 50) (Fig 1).  The sample reaches were selected using the aquatic master sample tool.  This tool relies on the GRTS method which produces random, spatially balanced points across the landscape of interest (Stevens and Olsen 2004).
