National Conservation Areas, designed to protect cultural, historical and recreational assets, range in size from 19 acres to 799,000 acres. The U.S. Bureau of Land Management’s 10-year-old National Landscape Conservation System, which includes the conservation areas as well as national monuments, wilderness areas and wild and scenic rivers, protects 27 million acres at almost 900 sites.
The National Conservation Area label that Trout Unlimited wants for 126,000 acres near Silverton called the Alpine Triangle would be the fourth such area in Colorado overseen by the BLM.
