Image of Alkaline Wing-nerved Moss
There are four Pterygoneurum species in Canada: P. kozlovii, P. lamellatum, P. ovatum and P. subsessile. The main feature that differentiates the Alkaline Wing-nerved Moss from the three other species is the fact that its mature capsules are immersed and lack a lid to allow the release of spores. (Updated 2008/05/20)
Pterygoneurum kozlovii is one of four species of Pterygoneurum in North America. It is a rather inconspicuous moss that forms small to medium sized patches on soil along alkaline wetlands in dry environments. Its most distinctive features are the small flaps that are found on the upper mid-ribs of the leaves and the immersed spore sacs that do not have a lid for spore release. (Updated 2017/05/25)
Distribution and Population
Globally, this moss is found in western North America, Europe, and western Asia. In Canada, it has been found in Saskatchewan and British Columbia. It is relatively widespread, but relatively uncommon, in south-central British Columbia. (Updated 2017/05/25)
This species is restricted to seasonally wet, alkaline soils in open, and dry areas of British Columbia. Eight of the known sites are undisturbed to relatively undisturbed, and eight are moderately to heavily disturbed. Most of the extant populations appear to be on provincially owned lands, in particular Crown lands, although ownership needs to be confirmed for some sites. (Updated 2017/05/25)
Pterygoneurum kozlovii is a small, acrocarpous moss that usually grows in small to medium sized patches or turfs along the edges of seasonally wet, alkaline areas. Sporophytes and spores are common in Canadian populations, and are probably important in maintaining local populations. (Updated 2017/05/25)
Impacts of grazing animals, urban development, road building, and human use of the habitat appear to be the main limiting factors and threats to Pterygoneurum kozlovii. Recent drought may also be a limiting factor. (Updated 2017/05/25)
Federal ProtectionThe Alkaline Wing-nerved Moss is protected under the federal Species at Risk Act (SARA). More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.
Alkaline Wing-nerved Moss in British Columbia and Saskatchewan is not protected under any provincial law.
