Cities comprise of mixed green patches that vary in size and are highly scattered and disconnected. Although small green spaces largely dominate the cityscape, they are often neglected and ignored by the naturalists and conservationists, as they do not fulfill the large green spaces criteria. The citizens on the other hand seem to have a different perception and requirements from small green spaces as they are within their neighbourhood. Bangalore, a developing city within South India, consists of a large number of newly formed residential areas which have pocket green spaces in the form of neighbourhood parks (henceforth NPs). They are maintained by the municipality and are mainly designed for recreation purposes, completely neglecting the fact that these spaces could be essential for biodiversity. Here, there is a disconnect between the requirements of the citizens, conservationists and the end product that the municipality delivers. Here, through a questionnaire survey we assess the biodiversity citizens are fond off, and use them as surrogate taxa for the not so immediately obvious taxa, insects to enumerate the biodiversity within NPs. We analyze and identify landscape characteristics around NPs which could enhance the biodiversity within NPs. Our results reveal that people are fond of Birds and Butterflies and we use them as surrogates for the inconspicuous taxa to assess biodiversity within NPs. 55 tree species, 45 species of birds, 41 species of butterflies and 68 morpho species of insects were recorded. We demonstrate that small green spaces are critical systems and help support biodiversity across three scale within the city. Interestingly, results suggests that density of NPs is more important rather than the size of NPs. Also, the presence of high density of NPs within a neighbourhood could support similar biodiversity that large green spaces support. Finally, this study provides insights on the landscape matrix that could help enhance biodiversity support service within NPs and the surrounding neighbourhood.
城市由大小不一、高度分散且不相连的混合绿地组成。尽管小型绿地在城市景观中占主导地位,但它们往往被自然学家和保护主义者忽视,因为它们不符合大型绿地的标准。另一方面,市民对小型绿地的看法和需求似乎有所不同,因为它们就在自己的社区内。班加罗尔是印度南部的一个发展中城市,拥有大量新形成的住宅区,这些住宅区都有口袋状的绿地,形式是邻里公园(以下简称 NPs)。它们由市政府维护,主要用于娱乐目的,完全忽略了这些空间对生物多样性可能至关重要的事实。在这里,市民、保护主义者和市政府提供的最终产品之间存在脱节。在这里,我们通过问卷调查来评估市民喜欢的生物多样性,并将其作为不那么明显的昆虫等类群的替代生物指标,来对 NPs 中的生物多样性进行计数。我们分析和确定了 NPs 周围的景观特征,这些特征可以提高 NPs 中的生物多样性。我们的结果表明,人们喜欢鸟类和蝴蝶,我们将它们作为不那么显眼的类群的替代生物指标,来评估 NPs 中的生物多样性。记录到了 55 种树木、45 种鸟类、41 种蝴蝶和 68 种形态物种的昆虫。我们证明,小型绿地是关键系统,可以帮助支持城市内三个尺度的生物多样性。有趣的是,结果表明,NPs 的密度比其大小更为重要。此外,一个社区内高密度的 NPs 可能支持与大型绿地相似的生物多样性。最后,这项研究提供了有助于提高 NPs 及其周围社区生物多样性支持服务的景观基质的见解。
