Description

Gillett's Checkerspot is a colourful and distinctive butterfly that has a very small global range and a global conservation status rank of imperiled/vulnerable. The species is relatively well known with respect to its biology and ecology. Available information is summarized in this report and differences between USA and Alberta populations are discussed. The ecology of the species renders it amenable to integration with economic activity. It can be accommodated without significant expense or impact on other natural resource uses. In some cases, forest canopy removal associated with development can be a positive factor for the species but in the past this has been an accidental byproduct of such activity. Brief strategic and operations guidelines are recommended.

Description

An overview was conducted of the butterflies of the Southern Headwaters at Risk Project (SHARP) area in extreme southwestern Alberta. The project resulted in compilation of a preliminary bibliography and a table of species known from the study area as well as those that may yet be found in the study area. Distribution and general habitat association is presented within a natural regions mapping framework. Peak flight periods are provided in summary form to aid future field surveys for target species. The SHARP area is the most productive area in the province in terms of butterfly species diversity. with 78 % of all known Alberta species known from this small comer of the province. The area is also home to 9 species that are not known from any other area of Alberta and 31 species that are considered to be species at risk. The area is therefore highly significant both provincially and nationally.
