A number of wooden boxes were put up some time ago for bats to roost in but these fell into disrepair, having been damaged by woodpeckers and squirrels. So, they were replaced using Schwegler woodcrete boxes of two designs (2FN cylindrical two entrance and 1FF flat single entrance) in Chris Klee's time with Bristol Water, and monitored by him and Avon Bat Group. Eventually, it was decided that YACWAG would take over monitoring of the boxes, which is how the situation stands today. Five more boxes, including a hibernation box (1FW), were added to the scheme during 2012-14 bringing the total to 41 boxes. I've added more boxes (2F and 2F DFP) as these work well elsewhere for Nathusius's Pipistrelles. I've also put up a 1FS in the Pumping Station grounds hoping to attract our Natterer's Bat group to use it.
