Elliot State Forest Appraisal
Coos County, OR

Turnstone conducted GIS-based analysis of threatened and endangered species occupancy and habitat as part of the appraisal process for the Elliot State Forest. Turnstone used three approaches to the analysis to identify areas for conservation. One approach used a draft Habitat Conservation Plan as guidance for prioritizing conservation areas and obectives. Another approach used stand-level inventory data and marbled-murrelet platform-density guidelines from the WA DNR to estimate likelihood of marbled murrelet occupancy. The third approach used historic data and guidelines from USFWS to identify areas known to be occupied by marbled murrelets and northern spotted owls.
