针对常见和广泛但数量减少的物种的野生动物保护政策很难有效地设计和执行，因为多种环境变化可能导致种群数量减少。保护行动的最终目标是影响人口增长率，但针对这些方面的可行改善行动对于分布广泛、涵盖广泛环境条件的物种来说具有挑战性。在整个欧洲，候鸟数量的急剧下降促使国际社会呼吁采取行动，但可能有助于恢复数量的行动尚未确定。采取有针对性的行动，改善质量差的场地的条件，可能是一种有效的办法，但只有在当地条件始终影响当地人口结构，从而影响人口趋势的情况下。在欧洲各地的调查地点，使用长期的丰度和繁殖鸟类的人口统计学措施，我们发现，共存的物种具有不同的迁移行为有类似的方向，当地的人口趋势和生产力的大小，但没有生存率。因此，采取有针对性的行动来提高欧洲的当地生产力，同时在非繁殖范围内进行大规模（非有针对性的）环境保护，可以帮助解决阻止迁徙陆鸟减少的迫切需要。为了应对全球野生动物减少的问题，可能越来越需要这种人口恢复途径。
Wildlife conservation policies directed at common and widespread, but declining, species are difficult to design and implement effectively, as multiple environmental changes are likely to contribute to population declines. Conservation actions ultimately aim to influence demographic rates, but targeting actions towards feasible improvements in these is challenging in widespread species with ranges that encompass a wide range of environmental conditions. Across Europe, sharp declines in the abundance of migratory landbirds have driven international calls for action, but actions that could feasibly contribute to population recovery have yet to be identified. Targeted actions to improve conditions on poor-quality sites could be an effective approach, but only if local conditions consistently influence local demography and hence population trends. Using long-term measures of abundance and demography of breeding birds at survey sites across Europe, we show that co-occurring species with differing migration behaviours have similar directions of local population trends and magnitudes of productivity, but not survival rates. Targeted actions to boost local productivity within Europe, alongside large-scale (non-targeted) environmental protection across non-breeding ranges, could therefore help address the urgent need to halt migrant landbird declines. Such demographic routes to recovery are likely to be increasingly needed to address global wildlife declines.
