Habitats at Cassop Vale include grassland, scrub, woodland and wetland, the last fed by spring-lines. The area also includes recolonised open quarries and mine spoil-heaps, which add to the floral diversity. The main grass species on the magnesian limestone is blue moor-grass "Sesleria albicans" amongst which grow fragrant orchid "Gymnadenia conopsea", cowslip, "Primula veris", rock rose "Helianthemum nummularium", and quaking grass, "Briza media". Several rare and local species are present, including globeflower, "Trollius europaeus", birds's-eye primrose, "Primula farinosa", lesser club-moss, "Selaginella selaginoides", and moonwort, "Botrychium lunaria". Elsewhere there is neutral grassland with red fescue and such herbs as cat’s-ear, earthnut and knapweed.
