Regeneration response and seedling bank dynamics on a Dendroctonus rufipennis‐killed Picea engelmannii landscape
Journal of Vegetation Science

Abstract
Despite some similarities to the high‐severity, infrequent/low‐severity, frequent conceptualization of regeneration response to disturbance, the high‐severity D. rufipennis outbreak is best described by explicitly considering host specificity and severity. Although, the outbreak simultaneously promoted both a pulse of P. tremuloides and a release of chronically regenerated A. lasiocarpa , the P. tremuloides response was generally masked by ungulate browsing, and the regeneration response came overwhelmingly from the A. lasiocarpa seedling bank. In this landscape, once dominated by P. engelmannii , the chronically regenerating seedling bank, typically thought to take advantage of canopy gaps associated with low‐severity disturbances, is poised to dominate forest reorganization in response to the host‐specific outbreak.
