The arboretum was established in 1912 by Thornton T. Munger of the United States Forest Service to determine the best trees for commercial purposes. Foresters planted tree species from various temperate and subtropical zones to compare their performance with local Pacific Northwest native tree species. After more than 90 years and 165 species tested, the general conclusion has been that native species are best adapted to the local environment. The Wind River is best known for its old-growth forests of Coast Douglas-fir and Western Hemlock. Other species include Western Redcedar and Pacific Silver Fir, Grand Fir, and Noble Fir. Understory trees include Pacific Yew, Vine Maple, Pacific Dogwood, and Red Alder. Much of the forest is more than 400 years old. == See also == * List of botanical gardens in the United States 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「Wind River Arboretum」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.
