In a more conspicuous sign of autumn, beech and other deciduous trees blanketing the hillsides start to sport reds and golds. The seasonal transformation was underway in southeast Poland’s Bieszczady National Park on October 8, 2026, when the OLI (Operational Land Imager) on the NASA-USGS Landsat 9 satellite captured this image.

European beech ( Fagus sylvatica ) dominates the area’s forests, with other species such as sycamore maple ( Acer pseudoplatanus ) also contributing to vibrant color in the fall. Dropping air temperatures and waning daylight cause these trees to curtail the production of chlorophyll , the molecule that plants use to synthesize food. Without it, the leaves’ green pigments fade, allowing the yellows and reds of other pigments to show through. A descendent of ice-age survivors, the European beech has persisted across millennia in a range of climates. After the glaciers retreated, beech forests spread northward across the European continent from isolated refugia in the Carpathians, Alps, and other mountain ranges, and played a crucial role in reforesting the previously ice-covered land. Portions of Bieszczady National Park are included within UNESCO’s network of ancient and primeval beech forests spanning 18 countries. Expansive as their footprint across Europe may be, beech forests reach only so high in elevation—about 1,000 to 1,260 meters (3,300 to 4,100 feet)—in this area. Above that is the realm of the polonina , a Slavic term for subalpine meadow, consisting of open grasslands and shrubby thickets of rowan (mountain ash), willows, and green alder. Patches of polonina stretch across ridge tops to the east-southeast of Smerek and appear tan, having lost their summer greenness . The Bieszczady Mountains are renowned not only for forests and mountain meadows but also for charismatic wildlife. European bison, once extinct in the wild , were reintroduced to the area in the 1960s and now roam the hills by the hundreds, according to recent surveys . Additionally, populations of brown bears and Eurasian lynx find refuge and ample food sources in the forests.
