摘要

摘要许多城市地区的绿地受到严重威胁;由于快速的城市化和蓬勃发展的房地产市场,绿地覆盖面积正在下降,栖息地质量正在恶化。因此,我们调查了一个自然遗迹地区的鸟类丰富度,并将其与之前发表在印度浦那花园、城市公园和学术校园文献中的物种丰富度数据进行了比较。在两年的调查中,我们在自然遗迹遗址记录了65种物种,其中15种在城市地区被认为是罕见的。在记录的物种中,有17种是栖息地专家,14种种群数量在下降。自然遗迹斑块一般公众无法进入;它们有下层植被和空中落叶,这可能是物种丰富度较高和稀有物种出现的原因。我们的研究结果表明,浦那的自然遗迹拥有独特且相对丰富的鸟类群落,从而为自然遗迹对城市生物多样性保护有价值的观点提供了进一步的支持。因此,我们建议在保护规划中应更多地关注小型、孤立的自然植被。

Natural remnants are refuges for rare birds in an urban area: a study from Pune city, India
Abstract The green spaces in many urban areas are under severe threats; the area under green cover is declining, habitat quality is deteriorating due to fast urbanisation and the booming real estate market. Therefore, we investigated the avian richness of a natural remnant area and compared it with species richness data previously published in the literature about gardens, urban parks, and academic campuses in Pune, India. In two years of our survey, we recorded 65 species at the natural remnant site, 15 of which are rare considered in urban areas. Among recorded species, 17 are habitat specialists and 14 have declining population. Natural remnant patches are generally inaccessible to the general public; they have undergrowth of vegetation and aerial leaf litter, which may be the reason for the higher species richness and the occurrence of rare species. Our findings indicate that the natural remnant site in Pune has a unique and relatively rich assemblage of bird species, thus provide further support for the notion that natural remnant sites are valuable for urban biodiversity conservation. Therefore, we suggest that small, isolated patches of natural vegetation should receive more attention in conservation planning.
