Species, Data, and Conservation Planning

摘要: Extinction is irreversible. The restoration of habitats, ecological processes, and ecosystem services complex but possible (Dobson et al. 1997a). We cannot, however, restore the building blocks those higher levels biological organization once species go extinct. For this reason, above all, we must consider minimization extinction rate our most urgent target measure conservation success. Molnar al., Higgins Cowling Pressey (2004, issue) contribute a variety insights on matter, for clarity response, synthesize their into five topics. start by addressing proposals these authors considering data targets three other scales organization: habitats or spatial classifications (hereafter land types, following Pressey), services. then tackle issue surrogacy between types. Finally, address some problems with species-based approaches. were invited to write initial essay (Brooks 2004a) build discussions setting biodiversity planning "argue that, despite range shortcomings, provide best basis targets." not charged report World Parks Congress in general (i.e., role Durban Accord, [http://www.iucn.org/themes/ wcpa/wpc2003/pdfs/outputs/wpc/durbanaccord.pdfl) Workshop Stream 7 (Building Comprehensive Protected Area Systems), which do elsewhere 2004b) collaboration number who respond here Conservation Biology article. emphasize that use word "armchair" was intended as derogatory.
