Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Redlisted as Near Threatened (2013) - Widespread but scarce in England, with shrinking distribution in recent decades (particularly in the North)
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Without evidence of the current national status of this species it will be very difficult to assess if there are any other species-specific actions required for its conservation; or if it is need of conservation at all.
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: There is no evidence that an increase in the structural diversity of the habitat will directly benefit this species.

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Low - Policy conflict (detail in comments)
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Reversing habitat fragmentation and improving habitat management at existing sites is key to the conservation of this species. The recovery potential is low because of policies around nitrogen deposition, which has a negative effect on mycorrhizal species like this.

Key Actions

Key Action 1

Proposed Action: An assessment of the necessary national species records should be made according to IUCN guidelines to provide a recognised redlist status criteria for this species.

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 1 year

Scale of Implementation: National

High priority sites: N/A

Comments: As the IUCN recognised assessment for this species is out of date, this action should be prioritised.
