CEMML’s history starts with a call to CSU from the US Army Corps of Engineers in 1985. USACE needed to develop a vegetation sampling scheme to inventory and monitor natural resource conditions on training lands. From that single project and a handful of employees three decades ago to an executive committee and over 350 specialists located on campus and on US bases and installations throughout the world today, the range of environmental research and applied expertise of CEMML’s impact continues to evolve. Cooperative agreements stretch across the military and governmental landscape. But one thing never changes – CEMML’s commitment to the dual imperative of environmental sustainability and mission readiness.
