Potentially lethal ground surface temperatures were measured at three locations in the Northern Rocky Mountains but occurred more frequently under treatments with greater overstory removal. Observed maximum and minimum temperatures of exposed surfaces are directly related to the thermal properties of the surface materials. Survival of planted seedlings was consistent with the pattern of potentially lethal temperatures. Care in manipulating overstory canopies and residues can enhance the potential for tree seedling survival.
