BAT SURVEY results June/August 2019
In conjunction with specialist monitoring equipment and analysis provided by The British Trust for Ornithology, the Wensum Woodlanders group have carried out three bat surveys in just part of the woodland areas affected by the 'Route C' announcement. These give an indication of the bat activity in the area.
Although weather conditions were far from ideal for part of the survey, the amount of data collected show these woodland areas to be populated by at least TEN DIFFERENT species of bats, including the rare and protected Barbastelle as well as the Nathusius pipistrelle.
Later in 2019 and regularly since, up to the present day, Charlotte and her team from Wild Wings Ecology came to these woodlands and did more involved surveys, including radio tracking the Barbastelle bats, to locate their maternity roosts. https://twitter.com/i/status/1223287366963646465
