Epitheca canis
Beaverpond Baskettail
| Scientific Name: | Epitheca canis |
|---|---|
| English Name: | Beaverpond Baskettail |
| Provincial Status Summary | |
| Status: | S4 |
| Date Status Assigned: | April 29, 2015 |
| Date Last Reviewed: | March 15, 2023 |
| Reasons: | Few sites are known, however there is potential for more, especially in the Interior of the province, where the range or number of occurrences may be considerably larger than present records indicate. The Lower Mainland populations are the most vulnerable, with urbanization and agricultural development the main threats; however, the species is relatively common and often abundant in the Fraser Valley and appears to be more widespread than earlier thought, and doing well (eg, Kenner 2000b). |
| Range | |
| Range Extent: | G = 200,000-2,500,000 square km |
| Range Extent Estimate (km2): | 206, 947 |
| Range Extent Comments: | This species is found from the lower mainland, one record on Vancouver Island and then scattered records north to the Peace River Valley and not including the southern dry valleys. The calculated range extent has not changed since calculated in 2004 from RBCM data and source points. |
| Area of Occupancy (km2): | FG = 126-2,500 |
| Area of Occupancy Comments: |
Disjunct, lower mainland, central BC and north east border. 37 x 4 sqkm = 148 sqkm // 11 historical RBCM not included. |
| Occurrences & Population | |
| Number of Occurrences: | C = 21 - 80 |
| Comments: | Found over a wide range but infrequently. There is likely many more locations than known, but much of the range, other than the lower mainland,is not terrifically accessible or well collected. The known habitat, marshy lakeshores, boggy ponds and backwaters of slowly flowing streams (Cannings 2002b) is relatively common over the range. |
| Number of Occurrences with Good Viability / Ecological Integrity: | Rank Factor not assessed |
| Number of Occurrences Appropriately Protected & Managed: | B = 1 - 3 |
| Population Size: | U = Unknown |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | CD = Medium - low |
| Comments: | The lower mainland populations are the most threatened: urbanization and agriculture with the associated drainage of wetlands the main threats. |
| Trend (in population, range, area occupied, and/or condition of occurrences) | |
| Short-Term Trend: | U = Unknown |
| Comments: |
Unknown: however the area where the most records are known from is the lower mainland where there have been significant wetland losses, therefore likely to show a decrease. |
| Long-Term Trend: | U = Unknown |
| Comments: | Unknown: however the area where the most records are known from is the lower mainland where there have been significant wetland losses, therefore likely to show a decrease. |
| Other Factors | |
| Intrinsic Vulnerability: | Rank Factor not assessed |
| Environmental Specificity: | Rank Factor not assessed |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
