She continued: "Thanks to our team of volunteers, our research will give us needed knowledge to better conserve bats and provide information and support for churches."She continued: "Thanks to our team of volunteers, our research will give us needed knowledge to better conserve bats and provide information and support for churches."
Ms Boothby said as grey long-eared bats look so similar to brown long-eared bats, a relatively common species, DNA testing of their droppings was one of the most effective ways to tell them apart.

She said because of that, it was likely the roosting sites of grey long-eared bats were under reported.She said because of that, it was likely the roosting sites of grey long-eared bats were under reported.

Over the course of the programme, conservationists worked to enhance 80 hectares of foraging habitat in Devon, and to improve the habitats between roosts in order to connect different colonies.Over the course of the programme, conservationists worked to enhance 80 hectares of foraging habitat in Devon, and to improve the habitats between roosts in order to connect different colonies.
The project also ran an education programme to increase awareness of the grey long-eared bat and improved the monitoring of the species.The project also ran an education programme to increase awareness of the grey long-eared bat and improved the monitoring of the species.
