1.1A number of species found only, or predominantly, in saline lagoons are listedas priority species under the UK Biodiversity Action Plan. The species considered to beassociated with saline lagoons are:
starlet sea anemone Nematostella vectensis
Ivell`s sea anemone Edwardsia ivelli
lagoon sandworm Armandia cirrhosa
the hydroid Clavopsella navis
lagoon sand shrimp Gammarus insensibilis
the lagoon seaslug Tenellia adspersa
Baltic stonewort Chara baltica
bearded stonewort Chara canescens
foxtail stonewort Lamprothamnium papulosum
bird`s nest stonewort Tolypella nidifica.
1.2Given the intimate association of the listed species with their lagoonalhabitat, and therefore between threats, actions and management for such species and thehabitat, it is considered appropriate to link the species with the saline lagoons habitataction plan. Consequently, all of the species (except the two anemone species for whichspecies action plans have already been published) are addressed through species statementsrather than being subject to individual species action plans. It is considered that thegroup steering the implementation of the habitat action plan will also address the speciesconcerned. It should be noted, however, that two species - Chara canescens and C.baltica - are also known from freshwater sites; this fact is reflected in the speciesstatements. The lagoons HAP does not encompass such sites and therefore these speciescannot be addressed solely by the saline lagoons HAP steering group.
1.3It should be noted that actions implemented for the saline lagoon habitatand for the species named here will also benefit other lagoon fauna and flora including anumber of other rare and/or specialist lagoonal species, eg Gammarus chevreuxi and Hydrobianeglecta.
2. Objectives for the species
2.1The objectives for the habitat will by default contribute to protection andconservation of the species with the exception of where they occur outside of salinelagoons. The following additional objectives apply to all the species
Maintain, and where appropriate enhance, existing populations and, whereappropriate, restore populations at former sites.
Maintain the range and number of sites including, where appropriate,through introduction to adjacent localities where existing localities become unsuitable.
3. Proposed action
Most of the actions listed for the habitat apply to the species and include anumber that are species-specific. The following additional generic actions should benoted.
Promote surveys to determine the full extent of each species including atformer localities. (ACTION: CCW, EHS, NE, SNH)
Ensure management and monitoring of relevant sites takes account of thespecies listed, and that species-related objectives and actions in management plans areacted on. (ACTION: CCW, EA, EHS, NE, SEPA, SNH)
Where appropriate, ensure habitat creation initiatives, including in thevicinity of present and former localities, take into account the requirements of thespecies. (ACTION: CCW, EHS, NE, LAs, SNH)
Where appropriate, determine the feasibility of former localities for thereintroduction of particular species. (ACTION: CCW, EHS, NE, LAs, SNH)
Where appropriate, consider further species-specific policy or legislativemeasures. (ACTION: CCW, DETR, DoNEI, EHS, NE, JNCC, NAW, SE, SNH)
Pass relevant information gathered during survey and monitoring to JNCC orBRC for incorporating into national databases. (ACTION: CCW, EHS, NE, SNH)
Provide information periodically to WCMC on the UK status of species tocontribute to up-to-date global red lists. (ACTION: JNCC)
Use the species as appropriate to raise awareness about saline lagoonhabitat conservation and management. (ACTION: CCW, DETR, EHS, NE, NAW, SE, SNH)
