This title is the result of a project which had three main aims. Firstly to collate all data as a permanent record in the county archive which would hopefully be utilised for conservation purposes. Secondly to map as accurately as possible the winter distribution of all species in the county; and finally to provide, in conjunction with the distribution maps, an estimate of the potential winter population of all species in the county.
