The catchment has several small reserve areas forming the Mary River National Park to help protect it. The Arnhem Highway crosses the river near one of the park areas.〔 It also supports multiple land uses including pastoralism, fishing, mining, defence force, tourism, conservation and horticulture. Pastoralism, particularly cattle grazing is the dominant use taking up 63% of the catchment area.〔 The river has a total of ten tributaries including the Little Mary River, MacKinlay River, Bowerbird Creek, Mingloo Cree and Douglas Creek. It has a mean annual outflow of , Its lower reaches form part of the Adelaide and Mary River Floodplains Important Bird Area. The river is noted for its population of saltwater crocodiles, and is breeding area for the Barramundi, the traget fish species for recreational anglers in the area.〔 It is one of eight rivers in the Northern Territory with a large floodplain system in their catchment area.〔(【引用サイトリンク】title=Mary River National Park )〕 The wetlands occupy an area of approximately and are predominantly freshwater, although they suffer from saltwater intrusion. The wetlands provide a mosaic of habitats and are listed in the Directory of Important Wetlands.〔(【引用サイトリンク】title=Mary River Salt Water Intrusion )〕 It is almost unique for an Australian river in that it has had no major tidal estuary as a river outlet for at least the last 2,000 years.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mary River (Northern Territory)」の詳細全文を読む スポンサード リンク
