Most spatial conservation planning for wide-ranging or migratory species is constrained by poor knowledge of species' spatiotemporal dynamics and is only based on static species' ranges. However, species have substantial variation in abundance across their range and migratory species have important spatiotemporal population dynamics. With growing ecological data and advancing analytics, both of these can be estimated and incorporated into spatial conservation planning. However, there is limited information on the degree to which including this information affects conservation planning. We compared the performance of systematic conservation prioritizations for different scenarios based on varying the input species' distributions by ecological metric (abundance distributions versus range maps) and temporal sampling resolution (weekly, monthly, or quarterly). We used the example of a community of 41 species of migratory shorebirds that breed in North America, and we used eBird data to produce weekly estimates of species' abundances and ranges. Abundance distributions at a monthly or weekly resolution led to prioritizations that most efficiently protected species throughout the full annual cycle. Conversely, spatial prioritizations based on species' ranges required more sites and left most species insufficiently protected for at least part of their annual cycle. Prioritizations with only quarterly species ranges were very inefficient as they needed to target 40% of species' ranges to include 10% of populations. We highlight the high value of abundance information for spatial conservation planning, which leads to more efficient and effective spatial prioritization for conservation. Overall, we provide evidence that spatial conservation planning for wide-ranging migratory species is most robust and efficient when informed by species' abundance information from the full annual cycle.

在迁移物种的空间保护规划中比较丰度分布和范围图。
大多数关于大范围或迁徙物种的空间保护规划都受到对物种时空动态的了解不足,并且仅基于静态物种的范围。但是,物种在其整个范围内的丰度都有很大变化,而迁徙物种则具有重要的时空种群动态。随着不断增长的生态数据和先进的分析,这两者都可以估算并纳入空间保护规划。但是,关于包含此信息对保护规划的影响程度的信息有限。我们根据生态指标(丰度分布与范围图)和时间采样分辨率(每周,每月或每季度)。我们以在北美繁殖的41种迁徙水鸟群落为例,并使用eBird数据来每周估算一次物种的丰度和范围。以每月或每周的分辨率进行的丰度分配导致了优先事项,从而在整个年度周期内最有效地保护了物种。相反,基于物种范围的空间优先排序需要更多的地点,并且至少在其年度周期的一部分中,大多数物种的保护程度不足。仅按季度确定物种范围的优先级效率很低,因为它们需要针对40%的物种范围以涵盖10%的种群。我们强调了丰富度信息对于空间保护规划的高价值,这样就可以更有效地进行空间优先保护。总体而言,我们提供的证据表明,当从整个年度周期中获取的物种丰富度信息为基础时,针对广泛迁徙物种的空间保护规划是最可靠和有效的。
