Effects of climate and land-use change on establishment and growth of cembran pine (Pinus cembra L.) over the timberline-treeline ecotone in the Central Swiss Alps
Tree growth is generally limited by temperature in cold climates and by water availability in and zones. Establishment in altitudinal treeline ecotones depends on the temperature, but may be very sensitive to water availability as well. We studied the effect of climate and land use on the colonizati...
