Small Mammals

Small predators like stoats, weasels and polecats are now a common sight in the rewilding project; and water shrews have reappeared in our streams and ponds.

Other small mammals, like the Harvest Mouse (Micromys minutus), weighing less than 10g, are rocketing. In Feb 2016, 59 breeding nests and 29 shelter nests were found in just five hours in the reeds around Knepp Mill Pond and Hammer Pond. 

So far, the Southern Block is proving the most productive for small mammals, the thick vegetation providing them with food and nesting habitat as well as protection from predators. A survey carried out over seven days in the summer of 2016 showed that between 17-32 of the 40 traps in the Southern Block contained either a Wood Mouse, Yellow-necked Field Mouse, Bank Vole, Field Vole or Common Shrew every time they were checked, compared with 2-5 captives in the 40 traps in both the Northern and Middle Blocks.

Hedgehogs, missing for over a decade, now also seem to be reappearing.
