NLCS units overlap. For example, Oregon’s Steens Mountain Cooperative Management and Protection Area contains Wilderness Study Areas, Wild and Scenic Rivers, and a Wilderness Area. Because of these overlaps, it is not possible to arrive at an acreage total for all NLCS units simply by adding the above totals for each unit. | Wilderness** | Wild and Scenic Rivers | National Trails*** | Wilderness Areas | Wilderness Study Areas | National Historic Trails | National Scenic Trails | Number | BLM Acres | Number | BLM Acres | Number | BLM Miles | BLM Acres | Number | BLM Miles | Number | BLM Miles | Alaska | | | 1 | 784,238 | 6 | 952 | 609,280 | 1 | 418 | | | Arizona | 47 | 1,396,466 | 2 | 63,930 | | | | 2 | 89 | 1 | 189 | California | 82 | 3,659,800 | 71 | 880,175 | 6 | 78 | 24,800 | 3 | 423 | | | Colorado | 4 | 139,524 | 54 | 621,737 | | | | 1 | 85 | 1 | 1 | Idaho | 1 | 802 | 66 | 1,321,298 | | | | 4 | 439 | 1 | 13 | Maryland | | | | | | | | | | 1 | 2 | Montana | 1 | 6,000 | 39 | 449,963 | 1 | 149 | 89,300 | 2 | 347 | 1 | 11 | Nevada | 45 | 2,056,545 | 63 | 2,552,457 | | | | 3 | 1,065 | | | New Mexico | 4 | 150,579 | 57 | 953,087 | 2 | 71 | 22,720 | 2 | 156 | 1 | 172 | Oregon/ Washington | 5 | 193,863 | 98 | 2,343,280 | 23 | 802 | 256,656 | 2 | 24 | 1 | 42 | Utah | 4 | 129,120 | 98 | 3,207,364 | | | | 3 | 569 | | | Wyoming | | | 42 | 575,841 | | | | 5 | 1,262 | 1 | 180 | Totals | 190 | 7,732,699 | 591 | 13,753,370 | 38 | 2,052 | 1,002,756 | 10 | 4,877 | 3 | 610 |
