This is also mirrored in the high number of invasive species. Overall, the regional
sensitivity of the habitats is lower than in the two other biogeographical regions
(Table 8.20). Like in the Continental region, the ecological envelope ranges from
medium but also high temperatures to habitat specific soil moisture demands
(Table 8.21, Fig. 8.10). The habitats are more or less indifferent in their sensitivity
against changing temperatures, but sensitive when changes in the soil moisture
occur during the vegetation period. The magnitude of the water balance, which is
