Landscapes Shaped by People and Place Institutions Require a New Conservation Agenda

Formal protected area systems will always be insufficient to sustain biodiversity and ecosystem processes. The largest proportions of endangered ecosystems and rare species remain outside public conservation areas on private land, and the political and financial costs of strategic acquisitions of these areas for conservation estate are becoming unaffordable. Although biologists quite rightly continue to call for development of more comprehensive and representative reserve networks, the reality is that the coverage, connectivity, and size of protected areas will remain inadequate (Shaffer et al. 2002). Many authors and participants, as well as the conclusions, of the very comprehensive 30-year review of the Endangered Species Act (Scott et al. 2006) noted the continuing challenge and urgency of extending the conservation agenda more comprehensively across natural and working landscapes (matrix lands), most of which will remain outside any formal reserve system. New integrative approaches are needed.
