摘要：Upland population levels are strongly correlated to environmental dynamics such as morphology, exposure and climate. A temperature fall leads to a shortening of the plant growth season, which can lead to lower pasture productivity and thus livestock can spend shorter periods in the mountains. The aim of this research is to correlate natural climate constraints with variation in the grasslands value in a selection of pastures located between 1100 and 1800 m in the Pasubio Massif (Italian Southern Alps, Trento). The correlation of this trend (derived from historical documents) with climatic oscillations in the same area derived from speleothems reveals that the variation in upland value was strictly linked to temperature and climate variations
