Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest
Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. Maintenance of the remaining intact boreal forest landscapes and restoring the structural and functional connectivity among...

Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. Maintenance of the remaining intact boreal forest landscapes and restoring the structural and functional connectivity among these remnants are essential for boreal forest conservation. In Sweden, such conservation tasks are highlighted in planning and implementing green infrastructure (GI). At the national level, the GI is established upon a network of high conservation value forests (HCVF). However, HCVF are insufficient to guarantee a functional GI and thereby cannot effectively halt boreal forest degradation. Forest restoration is urgently needed. This study explored a restoration approach based on connectivity forest (CF), i.e., forest areas with intermediate to high conservation likelihood prescribed by a new GIS-empowered artificial intelligence model. By step-wisely inserting the CF into the current GI, represented by the HCVF, this study assessed how the GI was reconfigured and strengthened over 1.3 million hectares of boreal landscapes in northern Sweden.
