While I cannot share sensitive information, the basis of todays survey was pretty defining in that 50% of the boxes onsite needed repairing. A figure that may increase upon checking inside the boxes which is on the agenda for our next visit with a group of volunteers.
Below is something I knocked up as part of a PDF that I've forwarded to all involved. Sensitive information isn't included and positioning of nest boxes are by no means accurate and to be used only as a guide for our volunteer workforce who will be conducting the work. 5
