Dynamics of subalpine forests

Learning Objectives

 

 

  • select the most limiting factors for tree growth in the subalpine environment
     
  • assign the form of tree rings to occurrences in the life of a tree
     
  • create subalpine forest communities by combining different mountain tree species
 

  • to differentiate between timberline, treeline ecotone and transition zone
     
  • to recognize indicators of former natural tree limits
     
  • to interpret tree rings
     
  • to distinguish the four phases of tree and stand development
     
  • to relate different tree species and forest communities to specific alpine regions

 

  • why tree growth has an altitudinal limit
     
  • how environmental conditions influence subalpine forests concerning their stand characteristics
     
  • why trees show different tree rings from year to year
     
  • tree and stand development
     
  • why the specific dispersal and regeneration mechanisms of subalpine trees are important for trees and forest communities
     
  • how different disturbances influence the structure and dynamic of subalpine forests
     
  • why and which different tree species can form together forest communities
     
  • processes influencing subalpine forests (natural and anthropogenic)
 

  • list the most important natural parameters limiting or inhibiting tree growth
     
  • draw the altitudinal zones, describe them and limits with their specific characteristics
     
  • recognize possible indicators of former natural tree limits
     
  • relate environmental influences to their corresponding effects upon tree rings
     
  • explain the mechanisms of dispersal and regeneration of different subalpine tree species
     
  • describe the phases of tree and stand development in the subalpine zone
     
  • explain important survival strategies of subalpine trees and possible disturbances
     
  • recognize Swiss Alpine coniferous forest communities
