Europe Landscape Restoration

Once blanketed with oak, birch, and hazel forests that housed Black Poplars and Arran Whitebeams, only a small fraction of the UK’s native woodland and peatland habitats still exist. Today, just 14% of the landscape's priority habitats are considered to be in good condition. Native biodiversity faces continued threats from intensive agriculture, pollution, and habitat fragmentation. Critically endangered species such as the Scottish Wildcat and Bechstein’s Bat have suffered from the loss of ancient forests and face extinction. One Tree Planted is helping reverse these trends by supporting forest restoration that fosters habitat connectivity between rural and peri-urban areas across the UK.

Stretching across Central and Eastern Europe, the Carpathians contain the largest expanse of old-growth temperate forest in Europe and are a biodiversity stronghold for species like the European Bison, Brown Bear, and Eurasian Lynx. The region plays a vital role in Europe’s freshwater systems and supports thousands of plant and animal species. However, land abandonment, agricultural pressure, and forest fragmentation threaten this vital landscape. One Tree Planted aims to expand forest biodiversity corridors and restore critical watersheds with an initial focus on Romania. In doing so, we’ll help reestablish ecological balance and see the region once again host native trees such as the Norway Spruce and European Yew.

The Mediterranean basin is the world’s second largest biodiversity hotspot and a landscape of extraordinary ecological and cultural significance. Centuries of human disturbance, paired with increasing wildfires, invasive species (such as the toxic Lantana Camera), and land degradation, led to just 17% of its original forest cover remaining intact by the early 2000s. Today, forests and wooded lands cover 28% of the region. One Tree Planted focuses on restoring rare habitats, enhancing riparian ecosystems, and promoting regenerative agriculture to strengthen the region’s resilience against natural disasters. Our long-term impact is rooted in rebuilding ecosystem services that support communities and wildlife, with a focus on restoring and connecting the region’s Natura 2000 sites across Portugal, Spain and Greece.
