al., (2012), the regional (absolute) characterisation factors were several orders of magnitude smaller. The
regional occupation and transformation impacts ranged between ecoregions by a factor 10 to over 180,
whereas the regional permanent impacts ranged from zero (ecoregions with no endemic mammals) to 2*10 -08
with a factor 80 from lowest to highest impact.
Table 1. Local and regional characterisation factors calculated for selected regions and land use types. The
respective units are indicated in brackets. The land use types follow the classification suggested in Kollner et
al., (2012b).
