Colonization and species replacement in permanent plots at different moraines of the Rotmoosferner glacier foreland (Obergurgl, Tyrol, Austria) (1996-2015)
At the glacier foreland of the Rotmoosferner (Obergurgl, Ötztal, Tyrol, Austria, 2300-2450 m a.s.l.) spatial and temporal trends in species dynamics and colonization are investigated in permanent plots, comparing vegetated and bare-ground plots. In total, 40 plots of 25 x 25 cm were established in 1996. One half of the plots was treated with a seed mixture in 1996 and 1997.
Research Questions
- development of vegetation cover and species richness
- dynamics on vegetated and bare-ground plots
- long-term effects of seed addition
- predictions of long-term changes
