BC Conservation Data Centre: Conservation Status Report
Jaumea carnosa
fleshy jaumea
| Scientific Name: | Jaumea carnosa |
|---|---|
| English Name: | fleshy jaumea |
| Provincial Status Summary | |
| Status: | S3S4 |
| Date Status Assigned: | March 31, 2018 |
| Date Last Reviewed: | April 30, 2019 |
| Reasons: | Fleshy jaumea has a range of < 1,000 square km in BC, and is currently known from 13-14 sites on Vancouver Island, Texada Island and at Pender Harbour. Data on population trends are unavailable, but this species is often locally common and is not known to be intrinsically vulnerable. No threats have been identified to BC populations, though coastal erosion, environmental pollution, recreation and invasive species have the potential to change community composition and disrupt ecological functions in salt marshes. |
| Range | |
| Range Extent: | C = 250-1,000 square km |
| Range Extent Comments: | The range extent in BC is < 1,000 square km, as calculated using GIS tools. At Long Beach in Pacific Rim National Park, various locations near Victoria, Texada Island and Pender Harbour . |
| Area of Occupancy (km2): | DE = 6-125 |
| Area of Occupancy Comments: | The area of occupancy is 52 square km, as calculated using a 2km x 2km grid. |
| Occurrences & Population | |
| Number of Occurrences: | BC = 6 - 80 |
| Comments: | There are at least 13 extant and one historical occurrence in BC. |
| Number of Occurrences with Good Viability / Ecological Integrity: | Rank Factor not assessed |
| Number of Occurrences Appropriately Protected & Managed: | Rank Factor not assessed |
| Population Size: | FH = 10,000 to >1,000,000 individuals |
| Comments: | Often locally common; at a marina in North Saanich, there is a very large population surrounding the entire shoreline and extending towards the ferry and south to Sidney (R. Batten, pers. comm.). |
| Threats (to population, occurrences, or area affected) | |
| Degree of Threat: | CD = Medium - low |
| Comments: | No threats to BC populations have been identified , though coastal erosion, environmental pollution, recreation and invasive species have the potential to change community composition and disrupt ecological functions in salt marshes. |
| 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: | C=Not intrinsically vulnerable |
| Comments: | Spreads easily via an extensive rhizome system. |
| Environmental Specificity: | C=Moderate. Generalist or community with some key requirements scarce. |
| Comments: | Found in saline tidal areas and marshes in the lowland zone. |
| Other Rank Considerations: | |
| Information Gaps | |
| Research Needs: | |
| Inventory Needs: | |
| Stewardship | |
| Protection: | |
| Management: | |
