State wildlife trails in the United States are state-sponsored systems of hiking and driving trails developed for the benefit of birdwatching and wildlife enthusiasts. They have been created and maintained by state governments or other state-level entities, both to promote ecology and to promote tourism. The term "trail" used in the names of most of these systems is, in general, a misnomer as that these trail networks are not single routes and are connected by motorways. These wildlife trail systems typically cover multiple wildlife viewing sites covering large areas of their respective states. Viewing sites may include nature preserves, state parks, national parks, and other venues.〔 The first of these trail systems was the Great Texas Coastal Birding Trail.〔(【引用サイトリンク】 date=May–June 2000 )〕〔〔 Numerous other trail systems have been opened throughout the country since. Apart from these state-maintained trail networks, some nature-advocacy groups and other entities have defined their own "trails" (a notable example being the Audubon Society's Great River Birding Trail that spans the entire Mississippi River). These are not discussed here. ==Trail systems by state== The following are state nature trails found in each state.〔(【引用サイトリンク】 title=Flyways North America's New Birding Trails )〕〔(【引用サイトリンク】 title=Birding Trails in North America )〕 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「State wildlife trails (United States)」の詳細全文を読む スポンサード リンク
