In the Bronze Age, the climate on Merseyside deteriorated, sea levels rose, and sand and shingle ridges formed on the coast, now visible up to a kilometre (0.6 miles) inland. Some small-scale farming may have taken place, but people generally still led mobile existences.
Bronze Age settlement sites in Manchester and the Pennines raise the possibility that Merseysiders had contacts over as wide an area as they had had in the Neolithic.
Although both cereal cultivation and animal husbandry took place on Merseyside, the evidence is much stronger for animal farming. However, with Wales and the Wirral acting as a protective barrier against the worst of the Atlantic weather, the banks of the Mersey would have been warmer and drier in the Bronze Age than other parts of the region, and well suited to growing crops.
