The National Cave and Karst Research Institute (NCKRI) is a nexus of research, stewardship, outreach and information for caves and karst while fostering interdisciplinary collaborations, created by the US Congress in 1998 in partnership with the National Park Service, State of New Mexico, and the City of Carlsbad.
NCKRI is located in Carlsbad, NM, and is a research center of the New Mexico Institute of Mining and Technology.
One of the major ecological threats to the sagebrush-dominated Great Basin ecosystem is the introduction and spread of dozens of species of non-native plants. The most important of these, cheatgrass (or downy brome) covers the largest area: 25 million acres, one-third of the area of the Great Basin.
