Naprimer, vključuje elemente starodavne kulturnekrajine in tudi povezano mrežo območijNATURA ter drugih območij biotopskegamrežnega sistema. Oblikuje cilje za posameznavarovana območja in jih združuje v splošnikoncept razvoja krajine. Na regionalni ravni je tolahko prvi korak k celostni raziskavi povezanostiv naravi.Lastne raziskave vrst in habitatovZa Bavarsko obstaja dobra osnova podatkov zaraziskave o vrstah in habitatih, na primer takoimenovani »Program varstva vrst in habitatov«.Tukaj se zbirajo in ocenjujejo rezultati različnihpopisov vrst in habitatov. Glede na določenovrsto in habitat daje dobro osnovo za nadaljnjeraziskave. Vendar v ta popis niso bile vključenevse vrste in habitati območij NATURA. Zato sobile potrebne nadaljnje raziskave o stanjuohranitve vrst in habitatov. Dve najpomembnejšitemi teh raziskav sta bili populacija netopirjev inpoplavni gozdovi. Potrebno je bilo zasnovatinovo raziskovalno metodologijo.Poleg tega so imenovani strokovnjaki naraziskovalnem območju kartirali pojavnostdoločenih ptic, navadnih škržkov in rib.4. Izvajanje raziskavKartiranje poplavnih gozdov, da bi ugotovilistanje ohranitveZa raziskovanje poplavnih gozdov je biloizdelano odločitveno drevo in usklajeno znaravovarstvenimi oblastmi. Odločitveno drevonavaja korake za razvrščanje obstoječih drevesin gozdov na območju. Rezultati tega kartiranjaso pokazali, da so bile številke iz standardnihpodatkovnih obrazcev včasih previsoke. Vresnici je bilo najdenih manj dejanskih poplavnihgozdov, kot je bilo pričakovati.Dodatni rezultat novega kartiranja inocenjevanja je bila opredelitev tistih gozdov, kibi jih lahko razvili v obnovljene habitate, če bi sepojavila potreba po zaključitvi povezane mreže.Ocenjevanje vpliva soli, uporabljene zaodtajanje ledu in modeliranje difuzijeKer so z vodo povezani habitati in vrstenajdragocenejši elementi v raziskovanihobmočjih NATURA, smo bili posebej pozorni naConcerning the NATURA sites along the motorwayroute, there is as yet no complete managementplan. Therefore one of the big efforts beforethe impact assessment was to completethe investigation on the occurrence of speciesand to assess the preservation state.From the LEK/LDC (Landscape DevelopmentConcept)Bavaria is divided into 18 regions for spatial planning.One of these is the region around Munich.The LDC is a compilation of data relevant tolandscape or environmental facts. For instance,it includes elements of the ancient cultural landscapeand also the coherent network ofNATURA sites and other sites of the biotope networksystem. It formulates goals for individualprotected assets and aggregates these into anoverall concept for the landscape development.On the regional scale this can be a first step intoa holistic investigation of natural coherences.Own investigations on relevant species andhabitatsFor Bavaria a good basis of data for investigationson species and habitats exists, for examplein the so called »Species and Habitats ProtectionProgramme«. Here the results of different mappingsof species and habitats are collected andassessed. According to the chosen species andhabitat it provides a good basis for further investigation.However not all of the relevant speciesand habitats in the NATURA sites were includedin this inventory. Further investigations on thestate of preservation of species and habitatswere therefore necessary. The two most importantitems of these investigations were bat populationand floodplain woods. A new investigationmethodology had to be designed.Additionally the stock of certain birds, fresh watermussels and fish was mapped in the investigationarea by designated specialists.4. Attending InvestigationsMapping of the floodplain woods for gettingto know the state of preservationFor investigating the floodplain woods a decisiontree has been worked out and aligned with thenature protection authorities. The decision treelists the following steps for classifying the existingtrees and woods in the site. The results ofthis mapping showed that the figures of thestandard data forms sometimes were prelimi-
