Fact of the week

Our pygmy shrews can eat 125% of their body weight every day! An average pygmy shrew weighs 4.1 grams and, averagely, munches through a daily 5.0 grams’ worth of insects, arachnids and woodlice.

A Nathusius’ bat was first identified in the reserve in 2019 by Richard Green, Lead Ecologist for the RPS Ecology Survey of Church Lane. This is just one of twelve species of bats identified in the reserve.
