Norfolk Bat Survey at Rocklands: 2nd O. S. grid square

The BTO are very quick and efficient in analysing the data generated through the Norfolk Bat Survey and I have just received the results of the second O. S. grid square that I covered.

On 2 August, the detector at my own house recorded just Common and Soprano Pipistrelles. At least this confirms the identity of the bats that roost in the shed at the bottom of the garden and hawk around the trees at dusk.

The following night, the same species, together with Brown Long-eared Bat were found at Walnut Tree Garden Nursery. Daubenton's bat may have been recorded as well.

The best night was 4 August, when the detector was set between two tall hedgerows close to a pond on the W side of Green Lane, at the end of Flymoor Lane. This was habitat for Natterer's, Noctule, Soprano and Common Pipistrelles. In addition, Daubentons, Leisler's, Serotine and Whiskered Bats were registered with low confidence. This just goes to show how a small amount of good habitat - simply tall hedgerows and a pond - can ensure that wildlife survives even in an otherwise barren agricultural wasteland.
