West Penwith Habitat Surveys: Trendrine Hill (part) (survey area 45 (part) – 2021) (NERR114)

Land within Penwith Moors, Cornwall, is being considered for designation as a Site of Special Scientific Interest (SSSI) under the Wildlife and Countryside Act 1981. Trendrine Hill and Beagletodn Downs was originally surveyed in 2013 by Hewins Ecology (commissioned by Natural England). That survey covered an extent of some 91.4 ha but excluded a section of land at the north-western edge of Trendrine Hill which has since been recognised as supporting semi-natural vegetation. To ascertain whether this land parcel meets the published guidelines for the selection of SSSIs a field survey was undertaken in September 2021. A walk-over survey was undertaken from which vegetation communities were identified and a rapid assessment of condition was undertaken consistent with Common Standards Monitoring. All plant communities present were mapped. Areas of lowland dry acid grassland were identified, and their condition assessed as unfavourable. This survey is one of many undertaken or commissioned by Natural England to provide the evidence required to identify those areas which should be included in an SSSI designation, to identify the features to be designated and to inform definition of the SSSI boundary. This report will also help to inform future site monitoring and to provide land management advice.
