OPEN MOSAIC HABITATS ON PREVIOUSLY DEVELOPEDLAND PHTGeneral DescriptionThis habitat specifically excludes the Calaminarian Grassland PHT. The habitat is efined in terms ofstructure, rather than specific vegetation communities. It comprises mosaics of bare ground, opengrassland, scrub and other fragmentary habitats. High quality examples may be characterised asunmanaged flower-rich grasslands with sparsely-vegetated areas on poor substrates.Invertebrate faunas can be species-rich and include many uncommon species. Between 12 and 15% ofall nationally rare and nationally scarce insects are recorded from brownfield sites.These sites mostly enjoy little recognition, their early successional communities and spearselyvegetated areas being commonly mistaken as being of no nature conservation interest. Morover, it israre today for such sites to survive lon enough to to acquire any value, which means those that doexist are effectively irreplaceable.The extent of this habitat in Cornwall is not currently known.For this habitat we will take all areasAppendix 4 - Information Relating to Priority Habitat TypesCounty Wildlife Sites Criteria
