Located on the south end of the city along Highway 219, this lowland area is a designated Important Bird Area and hosts such birds as buffleheads, dusky Canada geese, and tundra swans.〔(Jackson Bottom Wetlands Preserve. ) Oregon’s Important Bird Areas. Retrieved on January 29, 2012.〕 ==History== The Atfalati band of the Kalapuya people, who were the first inhabitants of the area, hunted and gathered in the area including hunting waterfowl and digging up camas roots. Then when European pioneers settled the area beginning in the 1830s farms were established in the area, with the wetlands area usually not being used due to the annual flooding. However, bridges were built across the river and steamboats plied the river before the railroads came to the valley.〔(Jackson Bottom Concept Master Plan. ) City of Hillsboro. Retrieved on October 4, 2007.〕 In 1910 the city of Hillsboro began using the Jackson Bottom area for water waste disposal. By the 1930s farmers in the community protested the water pollution that resulted from waste dumping into the river. Then in 1939 the city purchased part of the area and began using it as a sewer farm that produced a variety of produce and the city made some money off the venture. By the 1970s the city had acquired most of the land in that area, stopped using the farm, and let the area become grassland.〔 Next, in 1980 the Jackson Bottom Coordinated Resource Management Plan was developed and the area was transformed into a wetlands area.〔 In 1999, the wetlands received a National Wetlands Award for Education and Outreach from the Environmental Law Institute.〔Back, Shannon. "Goal of wetlands preserve: Welcoming humans", ''The Oregonian'', June 21, 1999.〕 Cougar sightings in June 2014 closed trails on several occasions. 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「Jackson Bottom Wetlands Preserve」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
