Long‐time effects of grazing on Patagonian rangelands (Argentina)

摘要：

Rangelands in the area of the Magellan Strait, southern Patagonia,are dominated by tussock grasslands of Festuca gracillima.The Open Tussock Grassland State seems stable, and may endure grazing with little physiognomic changes, but at some step irreversible transitions to dwarf‐shrub steppes of Nardophyllum brioides take place.
