Castle Bottom National Nature Reserve


Castle Bottom NNR is a small lowland site near Cricket Hill. It features one of the most important valley mires in southern England, with associated heathland and woodland habitats. The reserve is dominated by the two valley mire complexes which run through it, each with a small acidic stream running through the centre. The mires are mainly fed by water seeping out of the gravel beds at seepage steps. The two mires differ in community terms, the eastern being more open and dominated by bog myrtle and purple moor grass. There are small pools of open water, some natural and some man-made. There are also open areas with carpets of the bog-forming moss sphagnum. The western bog is grown over in many places with mature birch. The reserve currently supports 42 species of breeding heathland birds, with some rare and notable species such as Dartford warbler, nightjar and woodlark.
