The cover photograph shows a herd of alpacas(Vicugna pacos) grazing on high-altitude Andean peatlands known as bofedales in Sajama National Park(SNP),Bolivia's first protected area,established in 1939.In the background,the snow-capped Nevado Sajama(6,542 m a.s.l.),Bolivia's highest peak,dominates the landscape,with Polylepis tarapacana forests—considered the highest-elevation arboreal forests in the world—visible on its slopes.The image captures the intimate relationship between pastoral fivelihoods and mountain ecosystems that has sustained Aymara communities in the western Bolivian Andes for centuries.Located between 3,960 and 6,542 m a.s.l.,the park encompasses a diverse mosaic of ecological zones including peatlands,wet meadows,shrublands,grasslands,and high-Andean forests.Photograph was taken on April 16,2021 by Rosa Isela Meneses. 展开更多
