Bat Tree Survey Report Form<br />
4.0 FIELD SURVEY RESULTS:<br />
4.1 During the initial survey visit in December 2011, trees within the vicinity of the<br />
proposed alignment that had features associated with bat roosts (cavities, cracks,<br />
peeling bark, mature ivy growth, epicormic growth etc) were identified and notes on<br />
their suitability to support roosting bats were made.<br />
4.2 In February 2012 when further information was known on the alignment, an additional<br />
visit was undertaken to determine which if any trees could be lost under the<br />
proposals. This was followed by an aerial survey of trees at risk of removal in March<br />
2012. This survey used rope access and torches and an endoscope to undertake a<br />
close inspection of any potential roosting features and was carried out by a licensed<br />
bat ecologist and an arborist.<br />

sheets 1 to 9) and the supporting Survey Data Sheets (x1907.013 and 1907.3014).<br />
