BAP Volume 4: Priority Project List for Cornwall The following list of priority projects for Cornwall has been established through a series of workshops and consultations within the CBI. Below the projects have been split into three distinct topics, geographically based area projects, species projects and information gathering projects. Each project needs to be developed by the identified lead organisations and partners during the lifespan of this action plan. The development phase of each project will include setting targets for maintaining and restoring/expanding each BAP habitat associated with that project. These individual project targets will then contribute to the Local, Regional and National targets. Previous and existing projects should not be forgotten and should still be considered a valuable contribution to biodiversity within Cornwall. Best practice can be gained from these projects, for example a number of heathland projects have occurred in Cornwall, Tomorrows Heathland Heritage, Mid Cornwall Moors LIFE project and the HEATH project. A report has been produced by the CBI, Measuring BAP outcomes from landscape scale projects in Cornwall 10 which highlight the contributions these projects have had in delivering biodiversity targets. Appendix 2 contains a table showing which projects contribute to each BAP habitat and Appendix 3 shows the lead organisations and partners.
