Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: CR in GB & England. Confined to one locality in Britain, where highly sporadic in appearance & covering c. 30 x 30metres only
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Ecology not fully understood, but likely to involve targeted heavy grazing in particular seasons to maintain favoured short turf
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: This species would not benefit from untargeted management

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Low - Life history factor/s
National Monitoring Resource: Opportunistic - sufficient
Species Comments: Extremely rare in Britain, confined to a single site in Chilterns, where first discovered in 1875 (new to Britain) & later rediscovered in 1982. During 1980s, population numbered up to 50 or 150 plants on occasion, now typically present in single figures only.

Key Actions

Key Action 1

Proposed Action: Monitor plants on annual basis, precisely recording fate of individual plants to establish phenology / longevity etc. Record total population size, successful seed set, vegetation structure (e.g. height, % of open micro-sites) & general site conditions (e.g. soils & geology).

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Scientific research

Duration: >10 years

Scale of Implementation: 1 site

High priority sites: Bacombe & Coombe Hills SSSI

Comments:

Key Action 2

Proposed Action: Maintain & (if necessary) maintain sustainable grazing regime at Coombe HIll to ensure maintenance of short open sward with micro-sites for plant establishment & growth

Action targets: 5. Remedial action identified

Action type: Habitat management

Duration: 3-5 years

Scale of Implementation: 1 site

High priority sites: Bacombe & Coombe Hills SSSI

Comments: Gentinopsis ciliata likely to favour short to very short turf, with some microsites for seedling establishment.

Key Action 3

Proposed Action: Undertake management trials to maximise area of ground suitable for G. ciliata at Coombe Hill, including scrub clearance, mechanical creation of scrapes. tight mowing/strimming of sward, & vigorous raking.

Action targets: 5. Remedial action identified

Action type: Habitat creation

Duration: 3-5 years

Scale of Implementation: 1 site

High priority sites: Bacombe & Coombe Hills SSSI

Comments: Gentianopsis ciliata appears to occur within a narrow band at the boundary of various chalk strata with the overlying clay-with-flints. This interface extends for over 500 metres along the hill crest, & efforts should be made to ensure that all grassland here is in optimum condition for G. ciliata.
