About United Mountain Defense
United Mountain Defense (UMD) is a volunteer driven non-profit 501(c)(3) organization dedicated to protecting Tennessee’s environment and communities. Founded in 2005, UMD is composed of a workforce of long term volunteers, short term interns and an eight person volunteer board with a diverse background and over 30 years of combined experience working on environmental and social justice issues and non-profit management.

UMD works to halt the practices of mountaintop removal (MTR) and other destructive industries in Tennessee. UMD monitors coal corporations and their regulators, and holds them accountable through scientific monitoring, community organizing, engaging in the permitting process, and legal actions when appropriate. These activities are supported by conducting outreach and education on the issue of MTR and hosting anti-MTR events and actions. Activities are conducted within the state of Tennessee, primarily in Campbell, Claiborne, Scott, Fentress, Bledsoe, Knox, Blount, and Roane counties.
