IISD-ELA is located on Treaty 3 territory, the traditional land of the Anishinaabe Nation and the homeland of the M\u00e9tis Nation. It is a remote region of northwestern Ontario in Canada, approximately 250 km east of Winnipeg, Manitoba, or 50 km east of Kenora, Ontario.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1968,"yearClosed":null,"relatedSites":null,"siteName":"IISD
