Abstract Humans have impacted most of the planet, and ensuing fragmentation results in small, isolated habitat patches posing a risk genetic diversity loss, inbreeding, load. Understanding how natural anthropogenic landscape features affect gene flow among is critical for maintaining connectivity.

Many parts of Europe face increasing challenges managing wildfires. Although wildfire is an integral part certain ecosystems, fires in many places are becoming larger and more intense, driven largely by climate change, land abandonment, changes fuel management with important socioeconomic, environmental, ecosystem services consequences for Europe. In order to envision a comprehensive fire risk mitigation strategy Europe, spatial assessment opportunities manage fuels at the landscape-scale needed. Our study explored suitability three strategies (LMS)-herbivory, mechanical removal, prescribed burn-which can create heterogenous fuelscapes, thereby reducing element risk. We created maps each LMS using adoption factors identified systematic literature review (n = 123). compared these areas historical occurrence as proxy prioritize key intervention. found that over quarter was suitable multiple within greater risk, creating concurrent synergistic use strategies.

Currently, most low intensity relying on vegetation is found primarily marginal lands. These still host a high-level biodiversity but are subject to abandonment and agricultural intensification. Objectives Spatial information where grazed, how contextual geographic conditions encourage or limit missing, hindering their protection. We present an interdisciplinary approach map the spatial distribution European Union (EU) United Kingdom (UK). Methods first interviewed experts from countries, who provided us with estimates across selected land cover classes per environmental zone Member State. Subsequently, we analysed through maximum entropy modeling using pan-European in-situ data observations (using LUCAS, EU wide use survey) set characteristics representing local socio-economic, terrain, soil climatic context.
