在确定保护优先事项时，保护评估的准确性受到现有数据质量的限制。尽管以前的努力探索如何处理不完美的数据集，很少有人知道数据的不确定性如何转化为保护规划结果的错误。在这里，我们评估的委员会和遗漏的错误，有效性和效率的保护规划成果来自三个数据集的数据质量不断提高的幅度。我们证明，投资于数据采集可能并不总是最好的策略，因为新网站/物种引入的错误幅度可能超过所获得的好处。由于稀有物种的采样不佳，在有效性和效率之间存在权衡。鉴于数据获取受到所需高成本和时间的限制，我们建议在获取新数据时，重点提高不确定性最高的物种（稀有物种）的数据质量。
When identifying conservation priorities, the accuracy of conservation assessments is constrained by the quality of data available. Despite previous efforts exploring how to deal with imperfect datasets, little is known about how data uncertainty translates into errors in conservation planning outcomes. Here, we evaluate the magnitude of commission and omission error, effectiveness and efficiency of conservation planning outcomes derived from three datasets with increasing data quality. We demonstrate that investing in data acquisition might not always be the best strategy as the magnitude of errors introduced by new sites/species can exceed the benefits gained. There was a trade-off between effectiveness and efficiency due to poorly sampled rare species. Given that data acquisition is limited by the high cost and time required, we recommend focusing on improving the quality of data for those species with the highest level of uncertainty (rare species) when acquiring new data.
