However, in the case of hyperendemics it is possible to distinguish between
species living in mainland regions and on islands (Table 8). In general, invasive
and other problematic species, geological events and severe weather are assessed as
more problematic for hyperendemics on islands than in mainland regions. In contrary, pollution has a stronger impact in mainland regions than on islands.
