Natural Regeneration and Conservation Status of the Tree Community of Forest Remnants in Urban Parks in Southern Brazil

Abstract

Purpose: The study characterised the dynamics of the natural regeneration process of urban remnants in four Curitiba (PR, Brazil) urban parks, aiming to contribute to the green infrastructure management process in Araucaria Forest areas.
 
 Theoretical framework: Urban forests offer significant socio-environmental benefits, being relevant for maintaining ecosystem services for cities and their inhabitants. Studying the regeneration of forest remnants in urban environments is essential for analysing their conservation status.
 
 Method/design/approach: The floristic diversity, structure, and population dynamics of the shrub-regenerating component of urban forest remnants were studied through the analysis of phytosociological parameters and the similarity between the shrub-regenerating, and arboreal components was verified.
 
 Results and conclusion: Significant dissimilarity was found between the study areas' regenerating shrub and tree components. The forest remnant of the Municipal Zoo, located in a locality with greater integration of different green areas, showed the best conservation status and a more advanced process of forest succession.
 
 Research implications: The analysis of the natural regeneration of urban remnants serves as an essential diagnosis regarding their conservation status and the capacity of species to perpetuate in the place, in addition to inferring about the connectivity with other urban remnants, being of great importance for the planning of actions aimed at the management of urban forests.
 
 Originality value: Analyzing natural regeneration generates information on forest remnants' conservation status and resilience, which is essential for planning actions for urban forest management.
