有两个原因，在被动的野生动物恢复的战略规划：第一，最大限度地提高潜在的殖民化的恢复网站在挑战的景观，第二，最大限度地提高每个恢复项目的区域，管理区，生态系统，或目标物种的目标。景观配置和目标物种的人口/扩散特征可以决定野生动物对栖息地恢复项目的反应水平。在迅速郊区化的地区，这一点尤其适用于支离破碎的栖息地，在那里，野生动物可以在任何恢复的栖息地定居的广泛观念受到扩散障碍的挑战。由于栖息地恢复是恢复野生动物种群的一种被动手段，因此需要对恢复项目的背景（目标物种在现场定居的可能性）和内容（栖息地）给予同等的重视。定义人口统计学的空间格局，分散和分散允许生态学家将项目放在对目标物种的威胁和敏感性产生最大影响的地方，并对种群的持续和/或恢复做出最大贡献。此外，它还提供了一种评估不同恢复地点的相对潜在价值的方法。如果被动的野生动物恢复是成功的，殖民化的限制需要解释与生态系统和物种管理的区域目标。
There are two reasons for strategic planning in passive wildlife restoration: first, to maximize the potential for colonization of restoration sites in challenged landscapes, and second, to maximize the contribution of each restoration project to regional, management area, ecosystem, or target species goals. Landscape configuration and the demographic/dispersal characteristics of target species can govern the level of wildlife response to habitat restoration projects. This is particularly true for fragmented habitats in rapidly suburbanizing areas, where the widely held notion that wildlife can colonize any restored habitat is challenged by barriers to dispersal. Because habitat restoration is a passive means of restoring wildlife populations, equal weight needs to be given to the context (likelihood of site colonization by target species) as well as the content (habitat) of restoration projects. Defining spatial patterns of demography, dispersion, and dispersal allows restorationists to place projects where they can have the greatest impact on the threats and sensitivities of target species, and the greatest contribution to the persistence and/or recovery of populations. Further, it provides a means of evaluating the relative potential worth of different restoration sites. If passive wildlife restoration is to be successful, the constraints to colonization need to be interpreted with regional goals of ecosystem and species management in mind.
