Much has happened over the last year. There was the Dormouse Monitoring conference in November which covered various topics, including how to set up local and county dormice groups and how to undertake and promote suitable woodland management for dormice. Many counties and regions now have dormouse groups including Devon, Kent, Southend, Surrey, Sussex, Warwickshire, Lincolnshire and the North West Dormouse Partnership.

Questions can be asked over the precise planning of operations, such as: CLARE PENGELLY CLARE Is there enough refuge habitat provided? Does an adequate amount of breeding and feeding resources remain? And has connectivity been retained on site? This is especially true of larger-scale, more commercial operations. There are questions over the eff ects of operations on the displacement of dormice, and the consequences of this displacement on breeding and survival rates. There are ways in which protecting individual dormice can have population level conservation benefi ts, such as in preventing the One of the aims of the a rare opportunity to gain some of these questions complete removal of suitable study, therefore, is to insight into the dynamics of around management of habitat.
