In frame of the Large-scale con­ser­va­tion project is of nation­al­ly rep­re­sen­ta­tive impor­tance Asso­ci­a­tion of Friends of the Ger­man-Pol­ish Euro­pean Nation­al Park “Low­er Oder Val­ley” as spon­sor of the large-scale nature con­ser­va­tion project in the Insti­tute for Envi­ron­men­tal Stud­ies (IUS) com­mis­sioned the devel­op­ment of a main­te­nance and devel­op­ment plan in Hei­del­berg. This was dis­cussed in detail with the inter­est­ed pub­lic and agreed in May 1999 with rep­re­sen­ta­tives of the State of Bran­den­burg and the Fed­er­al Repub­lic of Germany.

The main­te­nance and devel­op­ment plan reg­u­lates the use of the indi­vid­ual areas for the core area. The aim is to design future use from a nature con­ser­va­tion point of view in such a way that the ecosys­tem, in par­tic­u­lar the flo­ra and fau­na, can devel­op and devel­op large­ly unaf­fect­ed by human influ­ence. Of course, the exist­ing eco­nom­ic, traf­fic and tourist use must be tak­en into account.

In par­tic­u­lar, the main­te­nance and devel­op­ment plan reg­u­lates the usage time and the usage inten­si­ty. In future, areas in the core area may not be used before June 30th. They can be used every year, some­times lat­er, for exam­ple, when it is the breed­ing behav­ior of cer­tain birds such as the Sedge War­bler (Acro­cephalus palu­di­co­la) or the Corn Crake (Crex crex) requires. The inten­si­ty of use is also restrict­ed, the use of fer­til­iz­ers and pes­ti­cides is for­bid­den, the stock­ing den­si­ty is lim­it­ed to one live­stock unit per hectare, the hay mead­ows should be cut with bar mow­ers that are gen­tle on small game and not with rotary mow­ers and should be cut as fine­ly as pos­si­ble and from the inside out. When graz­ing, the bank and for­est areas are pro­tect­ed from dam­age by ungu­lates by elec­tric fences.

In the for­est, for­eign woody plants and mono­cul­tures are grad­u­al­ly loos­ened or removed. The dry grass­lands are reg­u­lar­ly grazed by sheep (Ovis) to pre­vent encroachment.

Accord­ing to that Bran­den­burg Nation­al Park Act Half of the area, i.e. around 5,000 hectares, is to be tak­en out of use and left to nat­ur­al devel­op­ment (total reserves). The main­te­nance and devel­op­ment plan adheres to these legal require­ments. It envis­ages the devel­op­ment of around 50% of the area as a wilder­ness area that has not been used by humans. Accord­ing to the Nation­al Park Act, how­ev­er, the des­ig­na­tion of the total reserves is the respon­si­bil­i­ty of the nation­al nation­al park administration.

The main­te­nance and devel­op­ment plan has been con­tin­u­ous­ly devel­oped over the last 20 years, in par­tic­u­lar the nature con­ser­va­tion require­ments that are imposed on the agri­cul­tur­al ten­ants against rent reduc­tion. Despite these require­ments, the association’s agri­cul­tur­al area is in great demand among region­al ten­ants, not least because of the high EU agri­cul­tur­al sub­si­dies. Con­flicts with local agri­cul­ture, which in ear­li­er years were delib­er­ate­ly fueled by the state admin­is­tra­tion, albeit covert­ly, have not exist­ed since 2000, when the sup­port of the asso­ci­a­tion by the respon­si­ble Bran­den­burg Min­istry was abrupt­ly end­ed. The rela­tion­ship between the local farm­ers and the Nation­al Park Asso­ci­a­tion as landown­ers is objec­tive and based on partnership.

Togeth­er with the farm­ers, the restric­tions that are impor­tant for nature con­ser­va­tion are deter­mined on the one hand so reli­ably that the farm­ers can plan eco­nom­i­cal­ly, on the oth­er hand so flex­i­bly that the con­cen­tra­tion of rare breed­ing birds, which varies from year to year, can also be tak­en into account. The gen­er­al prin­ci­ple in a nation­al park is to keep human inter­fer­ence as low as possible.

Nev­er­the­less, it must be pos­si­ble to oper­ate eco­nom­i­cal­ly suc­cess­ful­ly on the 50% of the land in the nation­al park, which, in accor­dance with the will of the leg­is­la­ture, can still be used for agri­cul­ture. The Nation­al Park Asso­ci­a­tion has shown in the last 25 years when apply­ing the main­te­nance and devel­op­ment plan that this is pos­si­ble with a sense of pro­por­tion and com­mon sense.
