The area is a hot spot of natural habitats that are The protection of the area as a TBR is one of rare in Europe such as large floodplain forests, Europe’s most ambitious and exciting nature Active restoration measures are recommended river islands, gravel banks and oxbows.

(Schwarz 2007, compare figure 4). In total over 60% of the Lower Drava and Mura falls at least into the "good" hydromorphological assessment class (for the upper catchment including Austria this good classification can be estimated for only some 20% of the river courses).

The river system connects more than 400,000 ha of landscapes with extremely high natural and cultural values and an amazing biological diversity.
