| Reasons: | There are currently 18+ known occurrences of Impatiens aurella in British Columbia, 11 of which are considered extant. The range extent is 69,081 square kilometres and the area of occupancy is over 44 square kilometres with additional occurrences likely. |
| Range | |
| Range Extent: | F = 20,000-200,000 square km |
| Range Extent Comments: | The range extent for Impatiens aurella, calculated using a convex hull, is 69,081 square kilometres; sporadic in the Okanagan Valley and east to Creston with some historical outlying records further north. |
| 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 44 square kilometres. |
| Occurrences & Population | |
| Number of Occurrences: | BC = 6 - 80 |
| Comments: | There are currently 18+ known occurrences of Impatiens aurella in British Columbia, 11 of which are considered extant. |
| Number of Occurrences with Good Viability / Ecological Integrity: | C = 4 - 12 |
| Number of Occurrences Appropriately Protected & Managed: | Rank Factor not assessed |
| Population Size: | Rank Factor not assessed |
| Comments: | Population size is not considered an effective rank factor for plants with an annual life history. |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | D = Low |
| Comments: | No threats have been identified to existing populations and plants appear to benefit from moderate disturbance. |
| 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: | Found along moist streambanks and meadows in the steppe and montane zones growing in a variety of wetland types. One population is located in saturated, peaty, naturally-disturbed soil around a beaver-modified pond. At another site, plants grew at the pond edge, where soil has been disturbed by human activities. |
| Other Rank Considerations: | |
| Information Gaps | |
