Abstract:
Indicators for ecological quality in alpine pastures
Vascular plants are helpful indicators for the ecological quality.
In the context of the Ecological Quality Ordinance they
are already used in the utilized agricultural area. Recently, criteria
to assess the ecological quality of summer pastures have
been discussed. ART has identified the vascular plant taxa,
which best represent species richness, the occurrence of Red
List species and the occurrence of target and character species
following the environmental objectives for Swiss alpine
pastures. More than 3500 vegetation relevés were analysed
to constitute an indicator list containing 63 taxa. Based on
this indicator list and an appreciation by botanical experts the
share of alpine pasture reaching floristic quality is currently
estimated to be approximately 50 percent.
