Brown Grimmia (Grimmia elongata)
Key Details
| Taxonomic Groups: | Non-vascular plant (incl. chromists) > moss > Moss |
| Red List Status: | Least Concern (Not Relevant) [LC(nr)] |
| D5 Status: | Included in the baseline Red List Index for England (Wilkins, Wilson & Brown, 2022) |
| Section 41 Status: | (not listed) |
| Taxa Included Synonym: | (none) |
| UKSI Recommended Name: | Grimmia elongata |
| UKSI Recommended Authority: | Kaulf. |
| UKSI Recommended Qualifier: | (none specified) |
| Red List Citation: | Callaghan, 2023 |
| Notes on taxonomy/listing: | (none) |
Criteria
| Question 1: | Does species need conservation or recovery in England? |
| Response: | Yes |
| Justification: | Possibly qualifies as threatened with extinction in England due to small population size and/or restricted distribution |
| Question 2: | Does recovery/ conservation depend on species-specific actions? |
| Response: | Yes |
| Justification: | Species-specific surveys and data analysis are required to determine IUCN Red List status in England |
| Question 3: | At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages? |
| Response: | No |
| Justification: | The species has a restricted distribution and so is unlikely to benefit from untargeted actions |
Species Assessment
| Current step on the Species Recovery Curve (SRC): | 2. Biological status assessment exists |
| Recovery potential/expectation: | Low - Combination or other (detail in comments) |
| National Monitoring Resource: | Opportunistic - insufficient |
| Species Comments: | GB RL criteria: n/a. Arctic-montane Circumpolar species. Recovery potential low due to climate change and natural rarity. Potential additional action to: undertake research to better understand the ecology and habitat requirements of the species. |
