Definition of Favourable Conservation Status for Hazel or Common Dormouse, Muscardinus avellanarius (RP2951)

This document sets out Natural England’s view on Favourable Conservation Status (FCS) for Hazel or Common dormouse, Muscardinus avellanarius (referred to as hazel dormouse from here on) in England. FCS is defined in terms of three parameters: the natural range and distribution of the species; population of the species; extent and quality of habitat necessary for long-term maintenance of populations.
Section 2 provides the summary definition of FCS in England. Sections 3 – 6 describe the evidence considered when defining FCS for each of the three parameters. Annex 1 lists the references.
This document does not include any action planning, or describe actions, to achieve or maintain FCS. These will be presented separately, for example within strategy documents.
The guidance document Defining Favourable Conservation Status in England describes the Natural England approach to defining FCS.
