Potentilla sterneri

**Backfingerört (Potentilla sterneri)** Backfingerört is a rare perennial herb belonging to the rose family (Rosaceae). This small alpine plant produces characteristic five-petaled yellow flowers and palmate leaves divided into finger-like segments, giving rise to its Swedish common name meaning "back-finger herb." The species grows in low cushions or mats, typically reaching 5-15 centimeters in height, with a woody base that helps it withstand harsh mountain conditions. This critically endangered species is endemic to Scandinavia, with its range restricted to specific alpine and subalpine environments in Norway and possibly Sweden. Backfingerört inhabits rocky crevices, scree slopes, and exposed mineral soils at high elevations, where it has adapted to extreme temperature fluctuations and short growing seasons. The species faces significant conservation challenges, though specific threat assessments remain incomplete. Climate change poses a particular risk to high-altitude specialists like backfingerört, as warming temperatures can alter alpine ecosystems and enable competing vegetation to encroach on suitable habitat. The plant's extremely limited distribution makes it vulnerable to localized disturbances and genetic bottlenecks. Current conservation efforts focus primarily on monitoring existing populations and conducting taxonomic research to better understand the species' ecological requirements. Some populations may receive indirect protection through existing protected area designations in alpine regions. The outlook for backfingerört remains uncertain due to limited population data and incomplete threat assessments. Its critical conservation status reflects both its rarity and the urgent need for comprehensive research to guide effective conservation strategies.
