Metolius River Invasive Plant Surveys
Deschutes National Forest, OR

Turnstone was contracted by a federal agency to survey and map four invasive plant species: ribbongrass, reed canarygrass, yellow flag iris and false brome along approximately 10 miles of the Metolius River within the Deschutes National Forest, Oregon. High-accuracy GPS mapping of population extents allowed agency personnel to pinpoint eradication efforts and assess the possible impacts that eradication efforts may pose to other resources. of A total of 301 unique patches of target species were mapped during field surveys. To support planning efforts Turnstone created a map book detailing noxious weed locations and compiled a checklist of the nearly 200 vascular plant species identified within the survey area.
