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

SEPTEMBER

This is the last of the busy months in terms of field work at terrestrial sites as the season for monitoring butterflies, frogs, grazing animals and bats draws to an end. In rivers and lakes we sample diatoms for the third time in the year. The usual year-round measurements are also made.
