Methods of Including Invasive Species Research
in Urban Planning – A Case Study
on Ailanthus altissima

With the increased effects of urbanization, essential aspects such as green spaces or quality of residential areas were often reduced in importance in developing countries. At present green spaces in urban areas are facing problems related to invasive plant species, which have been introduced in order to mitigate potential environmental problems or to increase the landscaping values. The present research started from the existing documents on urban planning at national and local level and their consideration of invasive plant species. Based on these documents, we realized a spatial analysis of the distribution of Ailanthus altissima in an urban sample, with data generated from on-field mapping of presence, a data collector and comparison of results with a population survey. In order to collect data for analysis, 100 questionnaires were applied and a total of 1036 trees were mapped using the Survey 123 application. The results provide an overview of the presence and distribution of Ailanthus altissima in the different functional areas of the urban sample.
