The use of spatial concepts as a basis for designing a viable-habitat network: Conserving redstart (Phoenicurus phoenicurus) populations in Sherwood Forest, England

Abstract

Summary This paper presents a method for the design of a habitat network in a fragmented landscape. It employs metapopulation dynamics and connectivity to develop spatial rules which, together with the requirements of a target species, can be used to guide the creation of a network to improve population persistence. Using these guidelines, two conservation strategies of patch enlargement and corridor creation are developed. The spatial models used to produce the habitat network are described. The resulting maps show the network consisting of the source patches that could be occupied by stable populations and a number of patches, which could support viable local populations, situated in the proximity of the sources or linked to them. The approach could be used to inform decision-making in nature conservation and landscape planning.
