Epping Forest Act, have now grown massive crowns of thick, trunk-like branches with correspondingly large boles. This gives the trees an unusual appearance, not known in other forests. Often the weight of the branches cannot be supported by the parent tree, and the large amount of dead wood in the forest supports numerous rare species of fungi and invertebrates. Predominant tree species are Pedunculate oak ("Quercus robur"), European beech ("Fagus sylvatica"), European hornbeam ("Carpinus betuloides"), silver birch ("Betula pendula") and European holly ("Ilex aquifolium"). Indicator species of long-uninterrupted woodland include service-tree ("Sorbus torminalis") butcher's-broom ("Ruscus aculeatus") and drooping sedge ("Carex pendula") A
Cepaea sylvatica Cepaea sylvatica " Cepaea sylvatica" is a medium-sized species of air-breathing dextral land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. It is a close relative of the grove snail ("Cepaea nemoralis"). This species lives in many of the same habitats as "Cepaea nemoralis", such as woods, dunes and grassland, however "C. sylvatica" tolerates wetter and colder areas than the grove snail can tolerate. "Cepaea sylvatica" is generally similar in appearance to "C. nemoralis", although the shell is not as colorful and not as variable as that of the grove snail. Also, the diameter of the shell of
