An investigation of the effect of direct human impact and of advanced plant succession on Sequoia gigantea in Sequoia and Kings Canyon National Parks, California
Hartesveldt RJ. 1965. An investigation of the effect of direct human impact and of advanced plant succession on Sequoia gigantea in Sequoia and Kings Canyon National Parks, California. National Park Service
Various studies were conducted on giant sequoia to determine the effect of direct human impact and advanced plant succession. Factors studied include changes in growth rate following impact and the relationship of soil bulk density to root penetration. The soil moisture conditions beneath pavement, in areas of compacted soils, and in unmodified areas were measured and compared. It was found that only two types of human activity have caused a significant reduction in sequoia growth rate: pruning for road construction and the suppression of fires, which had allowed advanced plant succession and competition to increase.
