Picea glauca - Picea mariana / Rhododendron groenlandicum / Aulacomnium palustre
white spruce - black spruce / Labrador-tea / glow moss
| Scientific Name: | Picea glauca - Picea mariana / Rhododendron groenlandicum / Aulacomnium palustre |
|---|---|
| English Name: | white spruce - black spruce / Labrador-tea / glow moss |
| Provincial Status Summary | |
| Status: | S3 |
| Date Status Assigned: | April 08, 2011 |
| Date Last Reviewed: | April 08, 2011 |
| Reasons: | This bog forest is limited to very specific site conditions, generally as fringes associated with larger peatlands. The greatest threats are those that have an impact on the hydrological regime, whether it be drying or flooding of these sites. |
| Range | |
| Range Extent: | F = 20,000-200,000 square km |
| Range Extent Estimate (km2): | 153374 |
| Biogeoclimatic Unit: |
BWBSdk/Ws15
BWBSmk/Ws15 BWBSmw/Ws15 BWBSwk1/Ws15 |
| Range Extent Comments: | The range extent estimate of this ecological community is based on Version 9 of the Biogeclimatic Ecosystem Classification (BEC) map (B.C. Ministry of Forests, Lands, and Natural Resource Operations. 2014). |
| Spatial Pattern: | |
| Occurrences | |
| Number of Occurrences: | Rank Factor not assessed |
| Number of Occurrences with Good Viability / Ecological Integrity: | Rank Factor not assessed |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | B = High |
| Comments: | Land use activities that influence the hydrological regime, including linear corridors associated with transportation, mining and extensive oil and gas activities are the most likely threat to this poor swamp forest. These cumulative effects are considered to be moderate levels of threat which could be exacerbated by the effects of climate change now and in the future. |
| 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: | AB=Highly to moderately vulnerable. |
| Comments: | Low productivity sites which may require long periods to recover after disturbance. Susceptible to hydrological shifts associated with climate change. |
| Environmental Specificity: | B=Narrow. Specialist or community with key requirements common. |
| Comments: | This wetland is a poor swamp occurring around the edges of peatlands where there is some groundwater input from upland areas. |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
| Stewardship | |
| Protection: | |
| Management: | |
