Urban Parks in Curitiba as Biodiversity Refuges of Montane Mixed Ombrophilous Forests
The assessment of the conservation status of urban forest remnants is essential for sustaining tree diversity in metropolitan cities. This study evaluated the composition and structure of forest remnants in four urban parks within the natural distribution of Montane Mixed Ombrophilous Forest in Curitiba (PR, Brazil). We allocated 66 plots of 100 m2 and recorded all trees with perimeters at breast height ≥ 15 cm. A total of 1256 individuals from 44 botanical families and 117 tree species were identified, of which three are alien species. Tree density ranged from 1670 to 2095 trees ha−1, while the density of standing dead trees varied between 90 and 188 trees ha−1. We experienced values for the Shannon diversity index between 3.00 and 3.52 nats ind−1, which are comparable to the values for other non-urban forest remnants. Non-pioneer species represented 84.6% of the tree community (99 spp.), and 76% were zoochoric species (89 spp.). The research findings feed the discussion on the need of specific and integrated measures for the management of the urban parks reserved to the conservation of tree diversity in a specific phytoecological formation, while considering aspects of climate change and historical anthropisation.
