COSEWIC assessment and status report on the Alkaline Wing-nerved Moss in Canada

Summary of Status Report

The alkaline wing-nerved moss, Pterygoneurum kozlovii, is a small species that is restricted to Canadain North America. The species typically grows on soil among grasses and sedges along the margins of open alkaline wetlands in the drier regions of Canada. In Canada, it has been reported from 24 sites in south-central British Columbia, where it has been recently confirmed at 13 sites, and one site in Saskatchewan. Of the British Columbian sites, 6 may been lost to urban development, highway improvement, and trampling by cattle. Its presence at the Saskatchewan site has not been confirmed. About half of the all known sites are subject to grazing or human impacts.
