Dactylorhiza orchids are well represented, including the hybrids D. × grandis and D. × hallii.
A notable feature are the Dactylorhiza orchids which often form spectacular colonies 10–20 years post dumping, only to fade away again as the woodland thickens.
Orchid species include the Early Marsh Orchid (Dactylorhiza incarnata), and Hybrid Marsh Orchids such as D. fuchsii x incarnata and D. fuchsii x pratermissa.
These sites often support many typical chalk downland species such as Common Milkwort (Polygala vulgaris), Field Scabious (Knautia arvensis)and Salad Burnet (Sanguisorba minor) as well as orchids such as Fragrant (Gymnadenia conopsea), Common Spotted (Dactylorhiza fuchsii) and Pyramidal (Anacamptis pyramidalis).
