John Drewett has more than 40 years experience as a naturalist and conservationist. He spent many years carrying out voluntary work with the Surrey Wildlife Trust and studying the wildlife of south-east England before moving to Staffordshire in 1986 to take up a post with Staffordshire Wildlife Trust. In 1994 he settled in North Yorkshire where he established what is now known as John Drewett Ecology. As an experienced and fully licensed bat worker, John has built up a reputation for dependable and quality bat survey work. However, John's experience also extends to other protected species, mammals, breeding and wintering birds, plants and Phase 1 surveys. John works closely with six other associates, all of whom have been trained by John and hold Natural England bat licences. Through his associations built up over many years in the field of natural history, John is also able to utilise the skills of experts in other fields to offer a full range of ecological services to suit the requirements of projects great and small.
