摘要
Recovery planning is an important global conservation strategy for threatened species. Despite the existence of international standards for recovery planning, deficiencies and anomalies have been detected in several jurisdictions. This study evaluated the quality of recovery plans based on internal consistency as a measurement of coherent planning. We analyzed 236 plans developed by the Australian Government (1992-2006) using three criteria: (a) consistency of gaps in scientific information with prescribed research actions, (b) consistency of identified threats with prescribed threat abatement actions and (c) consistency of established plan objectives with performance evaluation criteria. These criteria were aggregated in order to calculate an index of plan consistency. We tested two hypotheses: (1) plans made for single-species would exhibit better consistency than those for multi-species; and (2) plans made under the amended legislation of the Environment Protection and Biodiversity Conservation Act (EPBCA) would exhibit better consistency than those under the rescinded Endangered Species Protection Act (ESPA). In total, over 85% of the plans consistently addressed the research needs. However, the plans addressed threats poorly (66% of all plans exhibited inconsistencies). Moreover, nearly 50% of all plans established inconsistent performance evaluation criteria. Under the ESPA, single- and multi-species plans exhibited equal consistency, but under the EPBCA, single-species plans clearly exhibited higher consistency. Our major contribution is the assessment of attributes of consistency that are paramount for effective recovery planning. Evaluation of these attributes may provide knowledge of universal utility and relevance to other biodiversity conservation efforts.
