| Provincial Status Summary | |
| Status: | S4 |
| Date Status Assigned: | |
| Date Last Reviewed: | March 22, 2024 |
| Reasons: | This species is widespread in the lower mainland but in relatively low numbers throughout its range. It has likely lost, and continues to lose, habitat in urban areas (Greater Vancouver), but has much intact habitat in the remainder of its range. |
| Range | |
| Range Extent: | F = 20,000-200,000 square km |
| Range Extent Estimate (km2): | 21,000 |
| Range Extent Comments: | Range extent is approximately 21 000 sq km based on the map in Nagorsen and Panter (2024). |
| Area of Occupancy (km2): | U = Unknown |
| Occurrences & Population | |
| Number of Occurrences: | D = 81 - 300 |
| Comments: | The map in Nagorsen and Panter (2024), indicates that there are likely at least 50 known occurrences, and probably more that are not yet known. There are 84 observations on iNaturalist (accessed February 2024). |
| Number of Occurrences with Good Viability / Ecological Integrity: | Rank Factor not assessed |
| Number of Occurrences Appropriately Protected & Managed: | Rank Factor not assessed |
| Population Size: | U = Unknown |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | U = Unknown |
| Comments: | Development likely threatens local populations via habitat loss and fragmentation, however the species' habitat is widespread outside urban areas in the lower mainland (Nagoorsen and Panter 2024, Zuleta and Galindo-Leal 1994; Kremaster et. al. 1993). |
| Trend (in population, range, area occupied, and/or condition of occurrences) | |
| Short-Term Trend: | U = Unknown |
| Long-Term Trend: | U = Unknown |
| Other Factors | |
| Intrinsic Vulnerability: | Rank Factor not assessed |
| Environmental Specificity: | Rank Factor not assessed |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
| Stewardship | |
| Protection: | |
