Although research has been done in order to understand the impact of urban development on avian diversity, it mainly focused on taxonomic diversity. Here we aimed to assess biodiversity targeting beyond species richness since this has the potential to inform the conservation of healthy functioning ecosystem. We explored how functional and phylogenetic diversity vary between a protected area and urban green spaces. We collected avian data at Lake Chivero Park and six green spaces in the city of Harare, Zimbabwe. The avian point count method at 30 sites for each location (Harare and Lake Chivero Park) was conducted. Alpha diversity indices were compared between Harare and Lake Chivero Park using independent t-test. One-way analysis of variance was applied to test for variation in functional and phylogenetic beta-diversity metrics together with the respective standardized effect size. Urban green spaces had higher species richness, abundance, phylogenetic and functional diversity than Lake Chivero Park. Beta diversity between the two sites was much higher than within sites diversity. The two sites did not differ in terms of beta diversity. Our study shows that urban development that incorporates green spaces maybe critical in the conservation of functional and phylogenetic diversity of avifauna. We suggest that urban landscapes be considered in national and regional conservation plans since they can act as conduits between protected areas, especially for avifauna.

尽管已经进行了研究以了解城市发展对鸟类多样性的影响，但主要集中在分类多样性上。在这里，我们旨在评估物种丰富度以外的生物多样性，因为这有可能为保护健康运作的生态系统提供信息。我们探讨了保护区和城市绿地之间的功能和系统发育多样性如何变化。我们在津巴布韦哈拉雷市的奇韦罗湖公园和六个绿地收集了鸟类数据。对每个地点（哈拉雷和奇韦罗湖公园）的 30 个地点进行了鸟类点计数法。使用独立t比较哈拉雷和奇维罗湖公园之间的 Alpha 多样性指数-测试。应用单向方差分析来测试功能和系统发育β多样性指标的变化以及各自的标准化效应大小。城市绿地的物种丰富度、丰度、系统发育和功能多样性均高于奇维罗湖公园。两个站点之间的 Beta 多样性远高于站点内部的多样性。这两个站点在 β 多样性方面没有差异。我们的研究表明，结合绿色空间的城市发展可能对保护鸟类的功能和系统发育多样性至关重要。我们建议在国家和区域保护计划中考虑城市景观，因为它们可以作为保护区之间的管道，特别是对于鸟类。
