Assessment of Marsh Fritillary (Euphydryas aurinia) Habitat Quality on Castlemartin Range Pembrokeshire (2015)
The marsh fritillary Euphydryas aurinia is an Annex II European protected species. The butterfly and its habitats are primary features of the Castlemartin Range Special Site of Scientific Interest (SSSI) in south Pembrokeshire. The metapopulation was discovered in 2003, too late to be included in the Limestone Coast of South West Wales Special Area of Conservation (SAC), but it is included as a key SSSI feature in the SAC Core Management Plan (CMP). Marsh fritillaries exhibit metapopulation dynamics, experiencing regular extinctions and colonisations of suitable patches over time. A large network of suitable sites is essential to maintain their populations in the long term. This survey was commissioned to examine potential marsh fritillary habitat on the Range and to determine the total amount and condition of habitat available for the metapopulation. All survey sites were on MOD Castlemartin Training Area, which in turn lies within the Pembrokeshire Coast National Park. The entire survey area is within the Castlemartin Range SSSI, and most of it is included in the Limestone Cliffs of Southwest Wales SAC.

NRW supplied the contractor with an outline map of the survey area, identifying approximately 360 hectares of grassland and heathland along the Castlemartin coast. These areas were believed to include all vegetation communities with the potential to support marsh fritillaries on the Range. Larval webs were recorded in the course of the habitat surveys. There was insufficient time to do a systematic transect survey, so these are only 'casual' records. All habitat was mapped following the standard NRW methodology. Land was classed into six categories, according to the presence and abundance of devil's-bit scabious. A tussocky sward structure is usually considered essential for marsh fritillary larvae, to provide shelter, hibernation and spring basking sites. Nearly all Welsh marsh fritillary populations are found in this type of habitat on damp rhos pasture.
