BACKGROUND: Butterfly Conservation is seeking an enthusiastic, knowledgeable, creative and highly organised Project Officer to deliver a new conservation project, Limestone Lepidoptera. The project will be based in the Yorkshire Dales and will seek to enthuse and educate volunteers about the key butterfly and moth species that this landscape supports. Once trained, volunteers will assist the Project Officer in surveying and monitoring species as well as identifying and mapping the sites where the species are present. The Project Officer will work with partners and other agencies in delivering management advice to landowners whose holdings support the most important populations of rare species and will engage in other relevant conservation activities, both practical and desk-based.
