Dry Matter Production of Trees at Timberline

  • Walter Tranquillini
Part of the Ecological Studies book series (ECOLSTUD, volume 31)


In the last chapter it was shown that growth of trees declines as one approaches the timberline, resulting in reduced stature and size of plant organs. This fall-off in growth could underlie an increasing shortage of organic materials, itself a consequence of deficient primary production. It is thus important to look closely at altitudinal changes in the primary production of trees. The magnitude of primary production in part determines the ability to compete with other plants and species, as well as the resistance to limiting environmental factors. Primary production, therefore, is of central importance in the occurrence of plants on specific sites.
