The low­er Oder Val­ley is one of the last near-nat­ur­al riv­er flood­plain land­scapes in Cen­tral Europe, vast­ly unde­vel­oped and some­times wild and harsh beau­ty. Over a length of 60 kilo­me­ters and an aver­age width of 3 kilo­me­ters, i.e. in a rel­a­tive­ly lim­it­ed space, it com­bines an abun­dance of very dif­fer­ent habi­tat types. On the one hand there are the aquat­ic habi­tats, where­by a dis­tinc­tion must be made between the riv­er or on the east­ern edge of the val­ley and the Hohen­saat­en-Friedrich­sthaler water­way on the west­ern edge of the val­ley, in between the many inter­con­nect­ed back­wa­ters in the flood­plain itself.

Sev­er­al crys­tal clear spring brooks arise from the slopes of the Oder val­ley, and there are also some larg­er rivers such as the Welse or Salvey­bach on the west and the Röhrike (Rurzy­ca) on the east. In the flood­plain itself, the exten­sive sedge, reed and reed stands are par­tic­u­lar­ly dis­tinc­tive, but so is the hard­wood and soft­wood allu­vial for­est, at least in rem­nants. On the val­ley slopes, the lat­er­al moraines of the Oder val­ley, which was formed as a glacial val­ley in the post-ice age, there are species-rich, nat­ur­al decid­u­ous forests, and flow­ery dry grass on the heights.
