Population viability analysis for conservation: the good, the bad and the undescribed

摘要: ABSTRACT Population viability analysis (PVA) is used in a variety of ways to solve conservation problems. These uses are defined part by data availability and theoretical biological understanding, social, regulatory political context. The use PVA one context does not preclude or invalidate its another. In this paper we attempt discuss objectively the role population management planning. We emphasise organising information, engaging stake-holders, making decisions. To be successful, some traditional views about models decision-making need suspended reviewed. INTRODUCTION biology at crossroads. 1980s many believed that would provide comprehensive framework for threatened-species management. Early enthusiasm has been tempered problems with lack data, validation, several studies have demonstrated sensitivity results uncertainty (Taylor, 1995; Ruckelshaus et al ., 1997). More more ecologists expressing disappointment inability verifiable answers, impregnable misinterpretation make work an academic ecologist any easier (Doak & Mills, 1994; Beissinger Westphal, 1998). Others who view from applied perspective tried it help environmental legislation, land-use planning decisions populations also disappointed (Hamilton Moller, Harcourt, 1995).
