3 â€“ East Anglian Chalk â€“ this is an open, generally tree-less landscape featuring beech shelter belts and copses. Arable farming dominates with cereals. Field margins are an important habitat. There is some wet woodland, and reed-bed, fen, coastal and flood plain grazing marsh habitats have developed on alkaline fen peat. Grazing marsh is scattered along the ridge spring line and the chalk streams are significant habitats for a wide variety of species. Patches of calcareous grassland are scattered throughout the area, and lowland meadow is found on unimproved loamy soils. Exposed faces in chalk pits, road cuttings and quarries are valuable sites for biodiversity. Climate Cambridgeshire has a maritime temperate climate which is broadly similar to the rest of the United Kingdom, though it is drier than the UK average due to its low altitude and easterly location, the prevailing south-westerly winds having already deposited moisture on higher ground further west. Average winter temperatures are cooler than the English average due to Cambridgeshire's inland location and relative nearness to continental Europe, which results in the moderating maritime influence being less strong. Snowfall is slightly more common than in western areas due to the relative winter coolness and easterly winds bringing occasional snow from the North Sea. In summer temperatures are average or slightly above due to less cloud cover. It reaches 25Â°C on around 10 days each year and is comparable to parts of Kent and East Anglia.
