Description

Soapweed was approved for provincial listing as an 'endangered' species in 2003. This vascular plant species has an obligate mutualistic relationship with its specialized moth pollinator, the yucca moth, which is also considered endangered both provincially and federally. There are two known natural populations; one population is on the Agriculture and Agri-food Canada Research Substation in Onefour and the other is on the Pinhorn Grrazing Reserve along half a kilometre of southwest-facing coulee slope of the Milk River drainage. Little is known about the Pinhorn population of soapweed, except that there is little evidence of sexual reproduction at the site.
