Chuckwalla National Monument Establishment and Joshua Tree National Park Expansion Act of 2023

This bill establishes the 661,000-acre Chuckwalla National Monument in California and expands Joshua Tree National Park by adding approximately 20,000 acres. It directly affects federally managed lands, culturally affiliated tribes (including Cahuilla, Chemehuevi, Mojave, Quechan, and Serrano nations), and local communities by requiring federal collaboration with tribes in managing the monument. Key mechanisms include creating a Tribal Commission for cultural input and an Advisory Council for management planning, mandating tribal consultation in resource decisions, and protecting traditional access to sacred sites. The law also restricts new grazing permits and outlines rules for recreation, wildlife, and infrastructure within the monument.
