Site types that use this protocol

Terrestrial

There are 15 species of bat, the only flying mammal, which are considered native to Britain where they are ubiquitous predators of insects.  Bats are known to be sensitive to changes in the environment, their numbers having declined significantly during the present century through a combination of loss of habitats, roost sites and food supply, and by increased frequency of disturbance.  Bats are therefore believed to be useful indicators of environmental change.

Species are mapped and their behaviour recorded on transects.

Our field activities

JULY

At terrestrial sites during July we continue with evening bat monitoring started in June, but bird surveying is complete. We also survey grazing animals this month, using a dropping count method. At freshwater sites we sample larger invertebrates. Of course, there's also a suite of year-round measurements to be made!
