Hemphillia camelus
Pale Jumping-slug
| Scientific Name: | Hemphillia camelus |
|---|---|
| English Name: | Pale Jumping-slug |
| Provincial Status Summary | |
| Status: | S3S4 |
| Date Status Assigned: | January 14, 2025 |
| Date Last Reviewed: | January 14, 2025 |
| Reasons: | This species is limited to south east British Columbia; it is vulnerable to logging and forest development. |
| Range | |
| Range Extent: | F = 20,000-200,000 square km |
| Range Extent Comments: | Approximately 53,000 km2 in southeast BC (Ovaska et al. 2019; iNaturalist, accessed 17 October 2024; GBIF, accessed 17 October 2024). It is found within the northern Columbia River basin, in the Kootenay region in British Columbia southward to the USA border. |
| Area of Occupancy (km2): | EF = 26-500 |
| Area of Occupancy Comments: | In 2015, the number of 4km grid cells was calculated by the CDC to be 26, but since then, there have been more observations in different areas. A wide range in the score (EF) is used as the surveys conducted have not estimated the area covered by this species or that there are more yet to be found. |
| Occurrences & Population | |
| Number of Occurrences: | D = 81 - 300 |
| Comments: | There are 85 sites identified in Ovaska et al. (2019); it was the most common slug found in places surveyed and was found at 27% of the sites reported on. |
| Number of Occurrences with Good Viability / Ecological Integrity: | U = Unknown |
| 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: |
The habitat of this species is vulnerable to logging and forest development (Nekola et al. 2011). The threats have not been quantified. |
| 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 |
| Environmental Specificity: | C=Moderate. Generalist or community with some key requirements scarce. |
| Comments: | Found in relatively undisturbed dry to moist coniferous forests where it lives on and around mossy stumps, rocks and logs; also in leaf litter (Forsyth 2004, 2014). |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
| Stewardship | |
| Protection: | |
| Management: | |
