In fact, giant sequoias need fairly frequent fires (at least a few a
century, if not more often) to propagate their progeny. Without the heat of a fire, the scales of their cones will not open to release the seeds, and the mineral soil and open forest they require to germinate will not be available. Sequoia trees are not only generally unharmed by fire due to their thick and only lightly flammable bark, their existence depends upon the heat of the flames. Intense fuel reduction in their groves is tantamount to forced local extinction. Similar cases are true for other kinds of trees; Sequoiadendron Giganteum is just the most dramatic example. The Giant Sequoia National Monument, which is an entirely different entity from Sequoia National Park, is also run in a different way. Unlike the park, which is run by NPS/Dept. of the Interior, whose mission and goal is to protect the resource unimpaired, it is run by the Forest Service, which has traditionally been a multiple-use and harvesting agency (except in wilderness areas, where preservation policies are generally stronger). The monument, which preserves most of the remaining sequoia groves not in the parks, also contains a good deal of intermixed and buffer forest, normally the Forest Service's bread and butter when it comes to harvest. I do not envy the Forest Service's resource specialists in this monument - they have a tougher time in many ways than the Park Service, who merely has to protect, or the regular national forests, where preservation is rarely practiced ona large scale and rapacious harvest can often be done with impunity. In the Monument, resource specialists have the balancing act of their lives when they must protect the Sequoia groves *and* provide for some level of harvest. These two conflicting goals give them an overwhelming management obstacle, both politically and in terms of the resource itself. When walking through some of the the groves in the Monument, it gives an odd feeling to walk among standing sequoia trees with little in between but low shrubs and grasses, compared to what one finds in the fully protected groves such as Giant Forest or Grant Grove or Redwood Mountain Grove. One wonders how much the longevity of the sequoia is owed to the presence of a forest around it to protect from the battering of strong winds in Sierra storms or the direct baking summer sun upon its entire root system. Time will tell, I suppose. One of the oddest groves is Converse Basin, where the Boole Tree, a very large old sequoia named for the foreman of the lumber company, stands alone among a few 100-year old trees and bushes. It is about the most incongruous sight I have seen, only matched by a few similar spots in the Pacific Northwest where single old giant redcedars have been preserved in the midst of what looks like a war zone. Other recently-established national monuments, including Mt. St. Helens National Volcanic in WA and Grand Staircase-Escalante in UT, have been modelled on similar frameworks, although St. Helens gets a stronger preservation component than some. If you have never been to these three National Monuments, I urge you to go - they are spectacular, fascinating and have enormous rewards to offer. Bruce Jensen |
