| Provincial Status Summary | |
| Status: | S2? |
| Date Status Assigned: | January 28, 2020 |
| Date Last Reviewed: | January 28, 2020 |
| Reasons: | Although a small range, there are considered to be few, if any, threats. |
| Range | |
| Range Extent: | A = <100 square km |
| Range Extent Comments: | The one BC location is within Stone Mountain Provincial Park. The next closest records are within Yukon Territory near the Tatshenshini-Alsek Provincial Park and it is likely that this species occurs within similar habitats within this park and area. The butterfly is holarctic, with additional Canadian populations in northern Manitoba and the western edge of Hudson's Bay. |
| Area of Occupancy (km2): | AE = 1-125 |
| Linear Distance of Occupancy: | U = Unknown |
| Area of Occupancy Comments: | Known populations are widely scattered and reported small in area (Guppy and Shepard 2001). |
| Occurrences & Population | |
| Number of Occurrences: | A = 1 - 5 |
| Comments: | Erebia pawlowskii is known only from one location in Stone Mountain Provincial Park, in the northern central part of the Peace Region although there are records on the border in Yukon Territory in the extreme northwest corner of BC and north of Tatshenshini-Alsek Provincial Park. |
| Number of Occurrences with Good Viability / Ecological Integrity: | U = Unknown |
| Number of Occurrences Appropriately Protected & Managed: | B = 1 - 3 |
| Comments: | Erebia pawlowskii is known from Stone Mountain Provincial Park. |
| Population Size: | U = Unknown |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | D = Low |
| Comments: | There is always the potential of mining and resource extraction. Blasting and quarrying for rock extraction is a possibility, although likely insignificant given the high availability of habitat. |
| Trend (in population, range, area occupied, and/or condition of occurrences) | |
| Short-Term Trend: | U = Unknown |
| Comments: | The habitat for this species is in high elevation boulder fields and scree slopes (Layberry et al. 1998), thus the threats to the species are minimal. |
| Long-Term Trend: | U = Unknown |
| Comments: | There is always the potential of mining and resource extraction. |
| Other Factors | |
| Intrinsic Vulnerability: | U=Unknown |
| Environmental Specificity: | C=Moderate. Generalist or community with some key requirements scarce. |
| Comments: | The larval foodplant requirments are probably grasses, sedges or rushes (Layberry et al. 1998; Opler et al. 1995) and females have been observed laying eggs on willow (Salix spp.) (Layberry et al. 1998). |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | Research is required to more accurately quantify specific habitat requirements including food plant density and patch size; species' dispersal capabilities, reproductive success and population viability; potential impacts of predation, parasitism, climatic variation, small population size, and population isolation is also needed. Research is required to assess the potential threats to habitat from potential mining and aggregate quarrying, invasive weeds, and wild fire. Research into life history is also needed. Research into subalpine and alpine butterflies, potential threats to these habitats, and life history information. |
| Inventory Needs: | Population and distribution in subalpine and alpine areas of BC, with a priority within Tatshenshini-Alsek Provincial Park as there are records for this species close to the BC-Yukon border. |
| Stewardship | |
| Protection: | Although protected within Stone Mountain Provincial Park, parks staff and contractors should be aware of and incorporate this species into management actions taken within the Summit Lake location. |
| Management: | Provisions for the species should be updated into the Stone Mountain Provincial Park Master Plan. |
