Question to the Department for Transport:

To ask Her Majesty’s Government how many bats are currently estimated to be using the bat bridges built over the Dobwalls bypass in Cornwall; and how that number compares with the number recorded at the opening of the bridges.

Dobwalls Bypass opened to traffic in December 2008 and included the construction of two purpose built bat bridges: Havett Farm Bridge and Lantoom Quarry Bridge. Sample monitoring of the effectiveness of the bridges has been undertaken. The surveys recorded 23 bat crossings over two days in June 2008, compared to a total of 39 bat crossings over two days in July 2014. The results of the surveys are not directly comparable as they were conducted in different months and at different times of day.
