Roz\u0161\u00edrenie:<\/strong> Ostrica Oederova je cirkumpol\u00e1rny tax\u00f3n. Vyskytuje sa v Severnej Amerike, ju\u017enom Gr\u00f3nsku, v \u00c1zii na \u010ealekom v\u00fdchode a v Japonsku. V Eur\u00f3pe rastie na Islande a Faersk\u00fdch ostrovoch, \u010falej takmer s\u00favislo od Britsk\u00fdch ostrovov a \u0160kandin\u00e1vie a\u017e do strednej \u010dasti Pyrenejsk\u00e9ho aj Apeninsk\u00e9ho poloostrova a po Ju\u017en\u00e9 Karpaty. Na Balk\u00e1ne a v celom v\u00fdchodnom Stredomor\u00ed ch\u00fdba.
\nV \u010ceskej republike sa vyskytuje na vhodn\u00fdch biotopoch ve\u013emi riedko roztr\u00fasene. Na Slovensku je situ\u00e1cia podobn\u00e1, viac lokal\u00edt je v severnej polovici \u00fazemia.<\/p>\n

Ekol\u00f3gia:<\/strong> Najviac lokal\u00edt je na slatinn\u00fdch ra\u0161elinisk\u00e1ch s vysok\u00fdm obsahom b\u00e1z, na miner\u00e1lne bohat\u00fdch aj extr\u00e9mne v\u00e1pnit\u00fdch p\u00f4dach (\u017eiv\u00e9 travert\u00ednisk\u00e1) s vysokou a st\u00e1lou hladinou podzemnej vody. Okrem slatinn\u00fdch ra\u0161elin\u00edsk obsadzuje aj plytk\u00e9 p\u00f4dy so slabo zapojenou veget\u00e1ciou. Na vy\u0165a\u017een\u00fdch slatinn\u00fdch ra\u0161elinisk\u00e1ch v prv\u00fdch rokoch po ukon\u010den\u00ed \u0165a\u017eby vytv\u00e1ra takmer \u010dist\u00e9 porasty vo ve\u013emi po\u010detn\u00fdch popul\u00e1ci\u00e1ch. Nesk\u00f4r pokryvnos\u0165 kles\u00e1. Ostrica Oederova sa vyskytuje od n\u00ed\u017ein do podhorsk\u00fdch pol\u00f4h. Kvitne od m\u00e1ja do j\u00fala.<\/p>\n
