Water voles
The results of the 2009 water vole survey carried out by the Water Vole Recovery Project (Berks, Bucks and Oxon Wildlife Trust) record water voles along the stretch of the river nearby ‘for the first time since 2003, with a significant increase in levels of activity from then’.
Grass snakes
There are also quite a few grass snakes on the estate. They favour the dense cover along the river but they can sometimes be seen basking in the sun during the first warms spell of spring.
