A productive day with 9 of us out. We spent the morning behind laptops helping everyone get their heads around IPMR and trying to work out the best way of sharing out the ominous task of historical data entry. Six of us then moved on to Holme Pierrepont to continue fighting the war against encroaching scrub. Whilst there, several Chiffchaffs sang, 3 or 4 Sand Martins came over, a Woodcock was flushed and Water Rails were heard. We left the site ready for action in a couple of weeks time.
