A loop trail and boardwalk off the Springwater Corridor runs through the park.〔 ==Ecology== A good area for bird-watching, the park attracts owls, pigeons, kingfishers, and herons.〔 In late spring and early summer, Tideman Johnson's big-leaf maples, alders, and other trees are frequented by warblers, grosbeaks and mourning doves. Other birds commonly seen in the park include sapsuckers, woodpeckers, chickadees, and bushtits. During a restoration project completed in 2006, workers identified 22 fish species in the creek at Tideman Johnson and counted 23 Chinook salmon and 107 steelhead trout.〔 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「Tideman Johnson Natural Area」の詳細全文を読む スポンサード リンク
