Ecological Solutions and Evidence

Abstract

The detrimental effects of human-induced environmental change on people and other species are acutely manifested in urban environments. While urban greenspaces are known to mitigate these effects and support functionally diverse ecological communities, evidence of the ecological outcomes of urban greening remains scarce. We use a longitudinal observational design to provide empirical evidence of the ecological benefits of greening actions. We show how a small greening action quickly led to large positive changes in the richness, demographic dynamics, and network structure of a depauperate insect community. We demonstrate how large ecological benefits may be derived from investing in small greening actions and how these contribute to bring indigenous species back to greenspaces where they have become rare or locally extinct. Our findings provide crucial evidence that support best practice in greenspace design and contribute to re-invigorate policies aimed at mitigating the negative impacts of urbanisation on people and other species.

摘要
人类活动诱发的环境变化对人类与其他物种造成的有害影响，在城市环境中体现得尤为显著。尽管城市绿地已被证实能够缓解此类负面影响，并支持功能多样的生态群落，但关于城市绿化行动所带来的生态结果的实证证据仍较为匮乏。
我们采用纵向观测设计，为绿化行动的生态效益提供了实证依据。研究表明，一项小型绿化行动可快速促使原本物种贫乏的昆虫群落的丰富度、种群动态及网络结构发生显著的正向变化。
我们证实，通过投入小型绿化行动可获得可观的生态效益，且此类行动有助于将本土物种重新引入那些已罕见或局部灭绝的绿地中。
本研究结果为绿地设计的最佳实践提供了关键证据，同时有助于推动相关政策革新，以缓解城市化对人类及其他物种造成的负面影响。
