Description

Area, 7.3 hectares 18.0 ac Description Hildersham Wood is an ancient woodland of ash maple type lying on the chalky Boulder Clay. Its ancient origin is reflected in the rich variety of woodland plants and associated communities which it supports. Such woodland habitat is now very localised in extent, both locally and in lowland England as a whole. In a Cambridgeshire context the wood is notable for a number of locally rare species. Although the wood is of the ash maple classification type these species do not dominate the tree canopy. Pendunculate oak Quercus robur forms the major canopy species, occurring as mature standards. The shrub layer is mainly of sparse hazel Corylus avellana coppice and hawthorn Crataegus monogyna. Ash Fraxinus excelsior occurs as occasional coppice throughout the wood and field maple Acer campestre is frequent as coppice and maiden trees. Typical shrubs include hawthorn Crataegus monogyna, blackthorn Prunus spinosa, guelder rose Viburnum opulus and a number of wild rose species Rosa sp. The ground flora is rich and variable. Dog’s mercury Mercurialis perennis and bluebell Hyacinthoides non-scripta are locally dominant but comparatively absent in other areas. Other species include early purple orchid Orchis mascula, remote sedge Carex remota, primrose Primula vulgaris and wood anemone Anemone nemorosa. Of additional note is the presence of a number of locally rare species such as broad leaved helleborine Epipactis helleborine, sweet woodruff Asperula odorata and oval and pale sedges Carex leporina and C. pallescens. A good number of ferns and mosses also occur reflecting the particular wetness of this woodland. The rides, which give additional diversity to the habitat, are generally wet and dominated by sedge species Carex spp. and other damp loving species such as meadowsweet Filipendula ulmaria.
