LEO is the world’s largest laboratory experiment in the interdisciplinary Earth sciences. The experiment consists of three artificial landscapes contained within elaborate steel structures outfitted with over 1800 sensors that monitor physical and chemical changes in LEO. The structures are located inside three adjacent bays that once housed the original Biospherians on a mission to measure survivability. Each structure measures 30 meters long, 11 meters wide, with an average slope of 10° and containing over one million pounds of crushed basalt rock. An alumnus of UA, Alan Ortega helped design LEO, and drew his inspiration from boat building and hull construction.

This involves interdisciplinary resource management in consultation and coordination with other federal, state and local agencies and Native American tribes. Specialists consider all components and values offered by public lands, including cultural, recreation, riparian, soils, wildlife, threatened and endangered species and critical watersheds. Additionally, rangelands belonging to Arizona’s three National Conservation Areas, 47 Wilderness Areas and five National Monuments are cared for with special regard for their national designations. BLM activities for Arizona’s grazing and rangeland program include resource monitoring, conducting land health assessments and evaluations, use authorizations, allotment planning and administration, developing vegetation objectives, integrating weed management and activity plan development in connection with land use planning. Livestock, fish and wildlife habitat, riparian, watersheds and other resources values benefit from improving the vegetative habitat and rangeland health of public land ecosystems. In Arizona, the BLM address all facets of managing range improvement development on […]
