Highly degraded habitats such as quarries often require active restoration efforts, but classical reclamation practices may undermine the occurrence of species that are locally rare or of conservation concern. We argue that some species can benefit from quarry landform whenever the presence of certain elements in the surroundings is preserved. We uncover the role of quarry landforms as providers of artificial habitat for the establishment of a bird of rocky habitats—the Black Redstart (Phoenicurus ochruros). We identified and monitored the location of territories of this species in seven quarries and their surroundings, over an entire breeding season. A multiscale approach was applied in order to take into account optimal spatial scales of response of the species to each habitat descriptor. We found this species mainly associated with quarried areas embedded within an inhospitable landscape. Mean slope, built‐up area, and number of habitats were important descriptors for Black Redstart territory location. Black Redstart territories are constrained at two scales. Core areas (0.25 ha) are mainly defined by optimal conditions for nest site location, where inaccessible rocky slopes provide safer places for nesting. At a larger scale (>2.00 ha) territories must enclose other land uses that deliver access to food supplies and offer good display positions to signal the limits of territories, allowing control of possible intruders. Localized actions aiming to maintain novel elements may result in the preservation of species such as the Black Redstart.

采石场能否为岩石栖息地的鸟类提供新的条件？

高度退化的栖息地（例如采石场）通常需要积极的恢复工作，但是经典的开垦实践可能会破坏当地稀有或具有保护意义的物种的发生。我们认为，只要保留周围环境中某些元素的存在，某些物种就可以从采石场地貌中受益。我们发现了采石场地貌作为人工栖息地提供者的作用，以建立岩石栖息地鸟-黑Redstart（Phoenicurus ochruros）。在整个繁殖季节中，我们确定并监视了该物种在七个采石场及其周围地区的位置。为了考虑物种对每个生境描述符的响应的最佳空间尺度，采用了多尺度方法。我们发现该物种主要与埋藏在荒凉景观中的采石场有关。平均坡度，建筑面积和栖息地数量是Black Redstart领土位置的重要描述。黑色Redstart领土被限制在两个尺度上。核心区域（0.25公顷）主要由巢址位置的最佳条件定义，无法到达的岩石斜坡为筑巢提供了更安全的场所。更大范围（> 2。00公顷）领土必须封闭其他土地使用，这些土地可​​以提供粮食供应并提供良好的展示位置，以表明领土的界限，从而可以控制可能的入侵者。旨在维护新颖元素的局部行动可能会导致诸如Black Redstart等物种的保存。
