There will be few surprises here for anyone with a knowledge of British fauna.
Harvest Mouse might be one as their distrbution and status is poorly understood, though several years of searching for their used breeding nests has shown them to be present more often than not.
Roe Deer have recently moved in to the area and Muntjac have probably been present for many years but this small (introduced) nocturnal deer is rarely seen or traced. The only record is of one on a late-night moth-trapping session.
