Arid-land bryophytes are poorly known both taxonomically and ecologically. Investigations have revealed, however, that there are at least 10 species that are considered at risk provincially, as well as nationally (Conservation Data Center 1998; Schofield 1998). All of these species are found in the semi-arid grasslands and steppe of the southcentral portions of British Columbia from the southern Okanagan through to Kamloops, and disjunct into the Fraser-Chilcotin area west of Williams Lake, with at least 3 of the species having their only known North American distributions here. In most cases, the at-risk species are either difficult to find because of their small stature or sporadic distribution, or are taxonomically problematic. Also, bryophytes, although useful as indicators of ecological conditions and important in the habitat stability of some sites, are not usually ranked high on lists of human concern...
