A unique network of peatlands, locally known as bofedales, are found in the highlands of the Central Andes in South America. We specifically focus on the Chilean bofedal network and evaluate year to year changes in vegetation productivity, as represented by 'greenness' (NDVI). We find that the accumulation of snow and rain over two years is an important climate influence on subsequent bofedal growing season productivity across the region. We also show that early summer minimum temperatures have a secondary influence on bofedal productivity at the regional level. Finally, we show that a recent greening (2013-2015) was preceded by years of high snow and rain accumulation.
