Abstract: Global changes caused by human activities cause serious threats to biodiversity and ecosystem services, from climate change to land-use change, and from urban to rural landscapes. In urbanising landscapes, several habitats are continuously lost and with them critical ecosystem services. In peri-urban and rural landscapes, devastating fires, as well as more or less unsustainable management, have major impacts. Among affected habitats, the forest is a key player, not at least when it comes to old-growth forests and their significance for carbon storage, and biodiversity. The continuous and widespread changes can be detected and monitored with increasing detail and accuracy using artificial intelligence, such as in the Digital Futures project EO-AI4GC. As a part of this project, we need to assess the ecological impacts of the detected changes. Since the changes are rapid and multifaceted and occur on different scales, we need digital tools for ecological assessment that can localise, quantify and compare habitat loss and fragmentation in an effective way. For this purpose, we build up digital ecological assessment tools including a set of virtual species, where their combined traits encompass those of real-world species and show more or less vulnerability to the landscape changes. In this seminar, I will present several studies on ecological assessment tools and their application in urban and rural landscapes.
