Patterns and processes in alpine vegetation

Vegetation


 

The local distributions of alpine plant species are the result of complex interactions among many factors such as:

  • type of soil
  • soil water availability
  • soil temperature
  • wind
  • snow depth
  • duration of snow cover
  • length of growing season
  • microclimate
  • disturbance
  • dispersal
  • interactions among plant species

Community development in alpine areas is far from being a uniform process: abrupt topographic changes at different scales and many types of disturbance acting at different spatial and temporal scales provide for a wide range of trajectories that community succession can take.


 
Act Let us walk along a transect that crosses 25 m of gently rolling terrain and see just how much the structure and composition of the vegetation change (Biet, 1900 m, Switzerland). Which factors and processes do you think are responsible for the observed small scale patterns?
