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

NOVEMBER

As we head towards winter, biological monitoring at terrestrial sites is scaled down, though we continue to record carabid beetles and spiders. At freshwater sites we make a limited set of measurements from November until February.
