- details of bat trapping and radio-tracking work undertaken
- baseline data for amphibians, reptiles and birds
- baseline data for designated sites, habitat surveys, and plants
- baseline data for otters, water voles, hazel dormice and bats
- baseline data for terrestrial invertebrates, aquatic macro-invertebrates and fish
