Read twice and referred to the Committee on Energy and Natural Resources.
Sponsored by Martin Heinrich (D-NM)
What it does
This bill would establish two new federally protected land designations in New Mexico's Caja del Rio plateau: a 67,163-acre Special Management Area within the Santa Fe National Forest (managed by the U.S. Forest Service) and a 17,837-acre National Conservation Area on Bureau of Land Management land. Both areas would be withdrawn from new mining, mineral leasing, and most new road construction. The bill would also require management plans developed in coordination with Indian Tribes, land grant communities, and local governments, and would authorize a land exchange between the federal government and the State of New Mexico to consolidate land ownership within the protected boundaries.
Who benefits
Federally recognized Indian Tribes with historic, cultural, or religious ties to the Caja del Rio area, who would gain formal roles in land management, guaranteed access for cultural and religious practices, and protections for sacred site locations. Land grant-merced communities and traditional historic communities with long-standing use rights (e.g., hunting, grazing, wood and piñon gathering) who would have those uses explicitly preserved. Hikers, wildlife watchers, and non-motorized recreationists who would benefit from reduced off-road vehicle activity. Wildlife and ecological interests served by habitat protection and ecological restoration provisions. The city of Santa Fe and Santa Fe County, whose existing drinking water infrastructure rights are explicitly protected. Conservation organizations seeking permanent land protections in the region.
Who is hurt
Off-road vehicle users and motorized recreationists who would lose access to undesignated roads and trails across roughly 85,000 acres. Mining and mineral extraction companies that would be permanently barred from new operations in the covered areas. Hunters who could face new restricted zones designated by the Secretary, though state jurisdiction over fish and wildlife is otherwise preserved. Ranchers and livestock operators, who may continue existing grazing but would be subject to new federal regulations and management plan requirements. New Mexico state government, which would be required to negotiate a land exchange and could lose some flexibility over state trust lands within the conservation boundary. Taxpayers who may bear administrative costs of new management plans, law enforcement presence, signage, and ecological restoration activities.
Supporters argue
Supporters argue that the Caja del Rio plateau contains irreplaceable cultural, archaeological, and ecological resources — including sacred Indigenous sites, Spanish colonial-era land grant heritage, and critical wildlife habitat — that face ongoing threats from unauthorized off-road vehicle use, vandalism, and illegal dumping. They contend the bill strikes a careful balance by explicitly preserving existing grazing rights, protecting Santa Fe's drinking water infrastructure, maintaining state jurisdiction over fish and wildlife, and centering Indigenous and land grant communities as co-managers rather than excluding them. They further argue that permanent federal protection is the only mechanism that can prevent future mineral or energy development from fragmenting this landscape adjacent to a major metropolitan area.
Opponents argue
Opponents argue that designating approximately 85,000 acres under restrictive federal management reduces the flexibility of local communities, the State of New Mexico, and future Congresses to respond to changing land-use needs, including energy development that could generate state revenue and jobs. They contend that road decommissioning requirements and motorized vehicle restrictions would effectively close large portions of currently accessible public land to working-class recreationists who rely on vehicles due to age, disability, or distance, disproportionately affecting rural New Mexicans. They further argue that exempting Indigenous plant and mineral collection from existing quantity regulations creates an unequal access framework on nominally public land that may be difficult to administer consistently.
