A Conservation Evaluation of Smooth Goosefoot, Chenopodium subglabrum (Chenopodiaceae), in Canada
2006
Robson, Diana Bizecki
Smooth Goosefoot (Chenopodium subglabrum) is restricted to North America and reaches its northern distribution limit in Alberta, Saskatchewan and Manitoba. The habitat of Chenopodium subglabrum contains some element of active sand. It is commonly found on the stabilizing edges of active dunes as well as dune blowouts, and occasionally on bare or recently disturbed sand plains. Chenopodium subglabrum is a sexually reproducing annual species with seeds that may remain in the seed bank for several years, waiting for the conditions it favours for germination. Germination of this species is erratic, possibly in response to moisture, making the overall population trend difficult to determine. The estimated population in Canada is likely between 5000 and 10000 individuals. There has been considerable loss of habitat as dunes become vegetated. The processes of dune stabilization and fire control threaten survival of this species.
