These subpopulations occur both on private and public lands. Fire, cutting or clearing of 'brush' to extend pasture, and competition by shrubs and trees are some of the major factors that negatively influence the abundance of Cypresses. A major burn all but destroyed the Cannell Creek grove several years ago (J. A. Bartel, e-mail comm.
