Urbanization plays a continuously increasing role and greatly contributes to habitat loss and fragmentation. To prevent biodiversity loss, the principle of \u201cno net loss of biodiversity\u201d, achieved by following a mitigation hierarchy (avoidance, reduction, and offsetting), has been proposed to be adopted in the process of environmental impact assessment. However, the method is typically used on a local scale project-by-project basis, ignoring the cumulated effects of several projects on habitat connectivity although it is a crucial component for species\u2019 long-term persistence. The aim of this study was to use spatial graphs to apply a landscape-level perspective to the mitigation hierarchy and to achieve a no net loss of connectivity due to urban development. A case-study concerning an endangered species, the Siberian flying squirrel (Pteromys volans), with ten examples of urban development projects planned by the city of Jyv\u00e4skyl\u00e4 was used. The ecological network of the flying squirrel was modeled as spatial graphs based on expert knowledge of species habitat requirements and movement behavior. Scenario analyses with connectivity metrics were used to quantify the effects of development projects and to identify the actions needed in the mitigation steps. Together development projects decreased the equivalent connectivity by 3.2 %. The effects of individual projects varied and revealed one project where avoidance could almost halve the total impacts. The analysis identified important network components within the project areas that could be maintained to reduce the impacts. The no net loss of connectivity was achieved by identifying and offsetting 14 new habitat patches that maximize connectivity. This study shows that spatial graph analysis can be used to identify and prioritize the actions needed in the mitigation hierarchy to maintain habitat connectivity in the landscape and thus provide important knowledge for conservation and decision makers in land use management.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-12-16T07:49:53Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-12-16T07:49:53Z (GMT).
