Conservation of species requires the protection of the associated suitable habitat. However, it is usually not known how much habitat is required to detect a single rare species. This problem is important, and it is related directly to the success and optimization of conservation planning. However, to date, no statistical methods have been developed to address this problem adequately. In this study, from a statistical sampling theory, we propose an estimator to estimate the minimum area required to conserve one or more additional new rare species. The estimator is highly accurate, as demonstrated by numerical tests. Applying the estimator in a tropical forest plot showed that the additional habitat size required for discovering an additional individual of a previously unseen tropical tree species is about 3.86 ha with a SE of 1.10 ha. In conclusion, the proposed estimator may be applied to conservation planning by assisting conservation biologists and policymakers to balance urban‐related and conservation‐related land uses by estimating the minimum detection areas required for species.

检测新稀有物种所需的最小栖息地大小


物种保护需要保护相关的适宜栖息地。然而，通常不知道检测单个稀有物种需要多少栖息地。这个问题很重要，它直接关系到保护规划的成功和优化。然而，迄今为止，还没有开发出统计方法来充分解决这个问题。在这项研究中，根据统计抽样理论，我们提出了一个估计器来估计保护一个或多个额外的新稀有物种所需的最小面积。正如数值测试所证明的那样，该估计器非常准确。将估计器应用于热带森林地块表明，发现以前未见过的热带树种的额外个体所需的额外栖息地大小约为 3.86 公顷，SE 为 1.10 公顷。总之，所提出的估计器可以通过协助保护生物学家和政策制定者通过估计物种所需的最小检测区域来平衡城市相关和保护相关的土地利用，从而应用于保护规划。
