Other Site Characteristics

Poloha: Lokalita se nachz na jižn Morave, asi 10 km S od Mikulova, mezi obcemi Strachotn a Doln Vestonice a silnic na Mikulov. Ndrž m rozlohu 4 km na dlku a 3 km na šrku. Ekotop: Oblast lež na neognnch (tretihorn) a kvartrnch pscito-jlovitch uloženinch. Spad do Dyjsko-moravsk nivy – akumulacn rovina. V tomto seku je zcela vyplnena vodn ndrž. Jedn se o rovinat zem tvoren prevžne vodn ndrž Nov Mlny. V ndrži lež nekolik ostrovu, nekter umele vytvoren. Prevldaj nivn pudy a gleje. Biota: Stredn ndrž Vodnho dla Nov Mlny lež na soutoku Dyje, Svratky a Jihlavy, v mste bvalch lužnch biotopu. V ndrži je velice rozdln vška vodn hladiny a již pri malm poklesu vody se vynoruj ostruvky. Pri hladine 170,35 m n. m. je vynoreno tmer 20 ha ostruvku ve dvou soustavch. Lokalita je vznamn jak v hnzdnm obdob, tak v obdob tahu i v zime.

4.2 Quality and importance

Stredn ndrž je vznamnm hnzdištem, tahovou zastvkou a zimovištem pro radu druhu ptku. Oblast byla vybrna s ohledem na hnzden rybka obecnho (Sterna hirundo), na tri zimujc druhy - orel morsk (Haliaeetus albicilla), husa poln (A. fabalis) a husa belocel (A. albifrons) a na podzimn shromaždište husy velk (Anser anser). Stredn ndrž je krome rybka obecnho tak nejvznamnejšm hnzdištem, zrzohlvky rudozob (Netta rufina) a racka chechtavho (Larus ridibundus) v Cesk republice. Rovnež je jedinm pravidelnm hnzdištem racka belohlavho (Larus cachinnans) a racka bournho (Larus canus) a jednm ze tr pravidelnch hnzdišt racka cernohlavho (Larus melanocephalus) v CR. Ješte donedvna predstavovala i nejvetš hnzdište husy velk (Anser anser). V prvn polovine 80. let minulho stolet na ndrži vznikla prvn kolonie kormorna velkho (Phalacrocorax carbo) v CR, kter sdl nyn v NPR Kriv jezero. Na ndrži se každorocne shromažduje vce než 20 000 kusu vodnch a mokradnch ptku. V dobe hnzden je to hlavne zsluhou kolonie racka chechtavho (Larus ridibundus), v zime bezkonkurecne prevldaj seversk husy, jejichž pocetnost doshla maxima v prvn polovine 90. let minulho stolet - odhadem 80 000-100 000 hus, z toho vce než 90 % husy poln (Anser fabalis). V poslednch zimch naopak prevažuj husy belocel (Anser albifrons). Stredn ndrž predstavuje rovnež nejvetš zimovište morcka malho (Mergus albellus) v CR. V dobe tahu je lokalita velice atraktivn pro mnoho druhu vodnch ptku (kachen, racku, rybku a bahnku) i pro radu pevcu.
