Nothochelone nemorosa
woodland penstemon
| Scientific Name: | Nothochelone nemorosa |
|---|---|
| English Name: | woodland penstemon |
| Provincial Status Summary | |
| Status: | S4 |
| Date Status Assigned: | April 30, 2021 |
| Date Last Reviewed: | April 30, 2021 |
| Reasons: | This species is plentiful in some valleys in coastal B.C. with a range extent of ca. 15,000 square km and at least 100,000 to 200,000 plants. There are at least 21 occurrences currently known but likely many others would be discovered if a thorough inventory would be completed. It is probably not very threatened. |
| Range | |
| Range Extent: | E = 5,000-20,000 square km |
| Range Extent Comments: | This species occurs over about 15,000 square km in B.C. (from GIS tools). |
| Area of Occupancy (km2): | U = Unknown |
| Occurrences & Population | |
| Number of Occurrences: | C = 21 - 80 |
| Comments: | There are at least 21 occurrences (including six historic that are quite possibly extant but no recent inventory to confirm) and likely many more. Recent inventory in the Homathko and Southgate valleys revealed 100 - 200,000 plants (C. Bjork pers. comm. 2007). |
| Number of Occurrences with Good Viability / Ecological Integrity: | U = Unknown |
| Comments: | At least two occurrences considered resilient and unthreatened (C. Bjork, pers. comm. 2007). |
| Number of Occurrences Appropriately Protected & Managed: | U = Unknown |
| Population Size: | G = 100,000 - 1,000,000 individuals |
| Comments: | There are an estimate of at least 100,000 to 200,000 plants in B.C. (C. Bjork, pers. comm. 2007). |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | Unknown |
| 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: | U=Unknown |
| Comments: | Probably not intrinsically vulnerable as it appears to reproduce well with large populations in Homalthko and Southgate valleys. Also, this species grows well in disturbed places (C. Bjork, pers. comm. 2007). |
| Environmental Specificity: | U=Unknown |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
| Stewardship | |
| Protection: | |
| Management: | |
