| English Name: | Olympic mountain aster |
| Provincial Status Summary | |
| Status: | S3S4 |
| Date Status Assigned: | March 31, 2022 |
| Date Last Reviewed: | March 31, 2022 |
| Reasons: | There are currently 13+ known occurrences of Eucephalus paucicapitatus in British Columbia, 9 of which are considered extant. The range extent is 3,107 square kilometres and the area of occupancy is over 36 square kilometres with additional occurrences possible. |
| Range | |
| Range Extent: | D = 1,000-5,000 square km |
| Range Extent Comments: | The range extent for Eucephalus paucicapitatus, calculated using a convex hull, is 3,107 square kilometres; sporadic in the mountains of central Vancouver Island. |
| Area of Occupancy (km2): | DE = 6-125 |
| Area of Occupancy Comments: | The area of occupancy, using a 2km x 2km grid cell for extant occurrences, is over 36 square kilometres. |
| Occurrences & Population | |
| Number of Occurrences: | BC = 6 - 80 |
| Comments: | There are currently 13+ known occurrences of Eucephalus paucicapitatus in British Columbia, 9 of which are considered extant. |
| Number of Occurrences with Good Viability / Ecological Integrity: | CD = 4 - 40 |
| Number of Occurrences Appropriately Protected & Managed: | C = 4 - 12 |
| Comments: | Several populations occur in provincial parks, where they are largely protected from major threats. |
| Population Size: | Rank Factor not assessed |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | D = Low |
| Comments: | The threat impact for this species is low. Limestone areas and their contact zones are potentially threatened with mineral exploration (H. Roemer, pers. comm. 2006), however, part of the population is probably effectively protected from major threat by location in provincial parks, and there are no known claims intersecting this species at this time. |
| Trend (in population, range, area occupied, and/or condition of occurrences) | |
| Short-Term Trend: | Rank Factor not assessed |
| Long-Term Trend: | Rank Factor not assessed |
| Other Factors | |
| Intrinsic Vulnerability: | Rank Factor not assessed |
| Environmental Specificity: | Rank Factor not assessed |
| Comments: | This species has been moderately correlated with limestones on Vancouver Island based on inventories by H. Roemer (pers. comm. 2006). |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
