This dataset is a set of geographic data layers (shapefiles and rasters) and connectivity measures (excel and txt-files) created during Maari Kosmas' master thesis, under the supervision of Rémi Duflot. The objectives of the study was to model the habitat network of the Siberian Flying Squirrel in the city of Jyväskylä, quantify the impact of the urban development plan on this network, and explore various avoidance, reduction, and offsetting scenarios to mitigate these impacts. The dataset consists of input data created based on data publicly available in Finland, more specific data for the study areas, and manual digitization from the authors (see publication for the list of data sources). Input data includes: potential habitat map, land cover map, development projects, mitigation scenarios etc... These data were analysed using the software Graphab, which create spatial graph and calculate connectivity metrics based on these graphs. The output dataset consists of geographic layers representing the spatial graph obtained at each step of the mitigation sequence: initial network, network after urban development, networks after the avoidance, reduction and offsetting actions. Only the results from each steps are included, not all tested scenarios. However, these can be reconstructed from the input data. Connectivity values are provided for all scenarios tested along these steps (as described in the input data). The dataset was gathered, processed, and analyzed between 2019-2020.
