Factors in Pinus ponderosa and Calocedrus decurrens mortality in Yosemite Valley, USA

Abstract: Management practices over the past 100 years, especially fire exclusion and suppression, in Yosemite Valley, Yosemite National Park, CA resulted in forest stands with basal areas in excess of 110 m 2 ha -1. Accelerated attack by several species of bark beetles (Scolytidae) followed a severe drought in 1976-77. Pinusponderosa, already under attack by root rot (Heterobasidion annosus) was affected severely, and mortality exceeded 70%. Calocedrus decurrens did not suffer comparable mortality and has replaced P. p… Show more

“…The consequence of this is an initial conversion of impacted areas to an overstory of incense-cedar. This increase in dominance of incense-cedar was also documented by Sherman and Warren (1988), who utilized earlier vegetation data of Gibbens and Heady (1964). Sherman and Warren (1988), however, did not discuss mortality of dominant and codominant incense-cedar in their paper.…”

Sherman and Warren (1988), however, did not discuss mortality of dominant and codominant incense-cedar in their paper. Given a longer time horizon, many incensecedars also die and leave openings in the forest canopy that are not occupied by trees.…”
