Carex chordorrhiza persisting in Oregon (January 15, 2009)
Carex chordorrhiza is native to bogs of northeastern North America. Its long stolons cause each individual plant to spread out, forming an extensive patch. The species was first collected in Oregon by Carex Working Group members in 1997 at two cranberry bogs, one each in Coos and Curry County. In 2006 the Coos County site was revisited and the plant was found again. It has resisted eradication attempts thus far, becoming a problem week in its cranberry bog habitat.
