Andrew Froud is an ecologist for the City of London Corporation and has been working with bats for more than 20 years. The primary focus of his bat-related research has been the ancient semi-natural wood-pastures of Epping Forest, Essex, examining the impacts of habitat management on the local bat population. He also has a broader focus on veteran tree management and the restoration and creation of dynamic habitats within the wood-pasture ecosystem.

Keith French was born and raised in the countryside. Working first with cattle and sheep, then as a gamekeeper on a small country estate, it was when he moved to Epping Forest, in 2001, that his interest in bats was born. Two years later, while attending a bat training course, he met the co-authors of this book; this led to them working together on many bat-related studies. Keith has been fortunate to record bats in some exotic locations such as the Amazon, Costa Rica, USA and several African countries.
