Reflections on Management Strategies of the Sequoia National Forest: A Grassroots View1 Carla A. Cloer 2 Abstract: In 1986, local citizens discovered that giant sequoia (Sequoiadendron giganteum [Lindl.] Buchholz) groves were being intensively logged by modified clearcutting which removed all vegetation around specimen sequoias in areas each up to 50 acres. After logging, the groves were to have plantations established in them. More than 1,000 acres in various groves had been approved for such treatment. When an administrative appeal to Sequoia National Forest failed to stop these projects, a lawsuit was filed, resulting in an injunction stopping the logging. Today, U.S. Department of Agriculture, Forest Service, policy precludes such intense logging, however groves on Forest Service lands remain unprotected by law. Logged-over groves need study to determine how best to restore them; thousands of seedlings planted in recently logged groves will result in crowded even-aged plantations; logging roads within groves need to be restored to natural conditions. It will take centuries to evaluate consequences of recent activities; intact portions of groves must have strictly minimum management so as to preserve options for future generations. At the turn of the century, logging abuses in groves of giant sequoia caused a public outcry which led to the formation of National Parks to protect many of the groves (Hartesveldt and others 1975). Most groves unprotected by National Parks were within Sequoia National Forest. The Forest's 38 groves were generally left alone until the Forest Service initiated a prescribed burn in the Bearskin Grove in 1975 (Rogers 1986). This initial experimental management of one small area of one grove was quickly followed by several decisions in rapid succession between 1982 and 1986 to intensely log within over 1,000 acres within giant sequoia groves (Cloer and Little 1987). For the most part, these decisions were made without public input. Beginning in 1987, following the lawsuit to stop such logging, public awareness and news media attention of logging activities in groves of giant sequoia has intensified. Articles in such magazines as Audubon (Green 1990), National Geographic (Findley 1990), Sierra, The San Diego Tribune (Levin 1987), as well as articles in the San Francisco Examiner (Kay 1992), and the Sacramento Bee (Knudson 1991) have raised public awareness that their favorite tree and the groves of which it is an integral part are not protected throughout their range; the groves in the National Forests have no statutory protection. This paper will describe the local citizens' battle to stop intense logging in groves and explain their insistence that the groves be legislatively protected. 1 An abbreviated version of this paper was presented at the Symposium on Giant Sequoias: Their Place in the Ecosystem and Society, June 23-25, 1992, Visalia, California. 2 Co-founder of Sequoia Forest Alliance; member, Executive Committee of the Kern-Kawaeeaah Chapter of the Sierra Club, Boards of the Rule River Conservancy and the Sequoia Forest Citizens Coalition; litigation committee of Tulare County Audubon. Address: 182 East Reid Avenue, Porterville, CA 93257. USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 Forest Service Policy In the southern Sierras, between the extremes of the granitic high country and the southern terminal ending in the Mojave Desert, lies the narrow Sierran conifer forest. Here the mixed-conifers including ponderosa, Jeffrey, and white pine, incense cedar, red and white fir, are reigned by the monarch of the Sierra, the giant sequoia, whose glowing red bark and magnificent size has inspired so many. In the early 1980's, local citizens, particularly those in the Kern Valley Wildlife Association, became alarmed by Sequoia National Forest's increase in using clearcutting in non-grove areas as a method of logging. This harsh treatment of the forest resulted in thousands of 10 to 40 acre patches where virtually no vegetation or wildlife remained after logging. The forest was being logged much too fast to meet the legal mandate for a sustained yield, and this logging was being done at a financial loss to the taxpayer (Rice 1991). The replanted pine seedlings often died in the hotter, dryer "clearcuts." The forest was becoming fragmented, stream sediments increased, riparian zones became damaged, ponderosa and Jeffrey pine plantations replaced true fir forests, and recreation and visual qualities were degraded. Soon the local Sierra Club became involved in logging issues, and local citizens formed Sequoia Forest Alliance. Although it was obvious that overlogging the forest adjacent to giant sequoia groves would eventually affect the groves themselves, there was no immediate concern for logging within giant sequoia groves. Not only was there the assumption that logging within groves was prohibited, many groves were posted with yellow signs which declared: Type I Redwood Grove Area Back of This Sign Established Under Reg U-3 by Regional Forester According to 1970 Region V Guidelines this meant that ..."no major activities such as campground or road construction, or timber cutting, will be permitted within any Type I Grove." This was the first specific Forest Service Manual direction for management of giant sequoias (Rogers 1985). Sequoia National Forest documents written between 1970 and 1984, including District Multiple-Use Plans, refer to various groves as being Type I. Then in the Fall of 1986, Charlene Little saw a timber sale ad which offered a "marginal amount of Giant Sequoia..." In response to her letter of concern Regional Forester, Zane G. Smith, Jr., wrote, "We have not changed our long standing Regional Direction for the management of the Sierra Redwood Groves" (Smith 1986). 129 Any reassurance from the above statement was short lived. One day in summer of 1986, while looking at nongrove areas, Charlene Little stumbled into a logged-over portion of the Long Meadow Grove. Roads had been pushed through the grove, large roots had been severed (Pintek 1987b), huge swaths of earth had been piled, all vegetation had been removed except for giant sequoias eight feet in diameter and larger; to the observers it appeared to be disastrous "nuclear" logging. What had happened to the Type I protection? The official response was, "Some grove boundaries were posted with Grove Type signs, but no groves were approved as Type I by the Regional Forester" (Crates 1987). They had no idea who had posted hundreds of signs. "Recent conversations with individuals that worked on the Forest during the 1960's and 1970's have indicated that much of the posting was probably done during the 1960's. We have no record of what the policy was prior to the May 1970 direction" (Crates 1987). Now there was a new grove designation system (USDA 1985). This new designation system had a category for preservation, but none of the logged groves were in that category. There was no law prohibiting logging in the groves, no law protecting the giant sequoias. When the Type I policy changed, apparently in 1985, the only written record available was an electronic mail transmittal sheet. There was no public involvement and no environmental studies which preceded the decision to change policy. Even if the policy had been changed in a proper manner, the following sales which allowed logging in groves had Decision Notices issued prior to the new policy transmittal date of 3/28/84: Red Sale (1982), Ridge 2 Sale (1982), Huckleberry Sale (1983), Eagle Sale (1983), Buck Sale (1983), Gauntlet Sale (1983), Wind Sale (1984) and sales in the Alder Creek Grove. Attempts to Stop the Logging Between August 1986 and March 1987, concerned citizens sent letters and petitions to the Supervisor of Sequoia National Forest, James A. Crates. He agreed not to approve any new projects within groves until a forest-wide giant sequoia management plan was written, but he would not stop sales already under contract (Crates 1987). This meant that two proposed sales which would have logged in the Freeman Creek Grove were stopped. However, over 457 acres (not including areas in Alder Creek Grove) had already been logged in groves; Mr. Crates was reaffirming his decision to log an additional 593 grove acres (Fisk 1986). Supervisor Crates' decision to not stop logging in groves was appealed to the Regional Forester; the appeal was rejected as "untimely." The only recourse available was to file a lawsuit and to request an injunction. In Sierra Club vs. The United States Forest Service [also described by Julie McDonald in these Proceedings (McDonald 1992)], the Sierra Club sought an injunction on nine timber sales, five of which involved logging in giant sequoia groves. A major issue was Sequoia National Forest's 130 failure to have an Environmental Impact Statement on any portion of its timber program. Sequoia National Forest argued that the logging was actually "grove enhancement" and was being done to release the sequoias from a buildup of non-sequoia species which were causing a fire hazard and inhibiting sequoia reproduction. During the lawsuit discovery process, however, Sequoia National Forest was unable to produce even a single study, map, or document which indicated that the specific areas approved for logging had been determined to have such conditions. There was a contradiction in their contention that the logging was to enhance sequoia reproduction because all of the stand prescriptions called for planting 75 percent pine and 25 percent sequoia at 10 by 10 foot spacing, creating an even-aged plantation. In actuality, they were committing those grove acres to the perpetual production of timber with its repeated cycle of logging, release, planting, thinning, and relogging. Why did they do this? Possibly some personnel actually believed that the logging would help the groves; however, an interview with former Regional Forester, Zane G. Smith, Jr., now retired, indicates that Sequoia National Forest was pressed to meet inflated logging volumes (Green 1990). Giant sequoias typically occupy the better timber growing sites (Rogers 1985); and about this same time Sequoia National Forest initiated clearcuts in other sensitive areas such as important viewsheds and very steep slopes. Conservation groups were convinced that any sequoia seedling that might become established after logging would in turn become logged during the next re-entry. Natural restoration occurred in the Converse Basin, where there was once the largest grove of giant sequoias known in the Sierra Nevada before the turn-of-the-century logging (Harvey 1985). Sequoias which had germinated from the natural seed bed had grown to considerable size, up to six feet in diameter. In the Cabin Sale (1985), however, not only were non-sequoia trees logged, but the sequoias that were replacements for their logged ancestors were also cut. Sequoia Forest explained that these trees were "second growth" and therefore they did not qualify for sparing. By the same logic, any sequoia tree which was established after the more recent logging would also be "second growth" and available for logging. Experts found that the type of logging occurring in the groves could cause significant environmental impacts (Rundel 1987 and Stephenson 1987). While waiting for the judge to rule, logging continued in the groves. Local citizens watched as survey stakes were replaced by bulldozed roads and then every living thing was removed from the units except for the largest giants. About 16 months after the lawsuit was filed, the Ninth Circuit Court of Appeals granted us an injunction. The case was won, not because it was illegal to log in groves, but because of the lack of an Environmental Impact Statement. Because of court delays, only four units in groves were saved: two in the Peyrone Grove and two in the Red Hill Grove. The precedent was set, however, that the groves were not to be treated the same as any ordinary piece of the forest. USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 Planted pine seedlings line up in shadow of the 150- to 300-year-old trees they replace in a unit of the Black Mountain Grove, Tule River Ranger District of Sequoia National Forest, logged in 1988. This type of logging in groves is termed "non-intensive" management; in 1986, 9,300 acres within groves were assigned to "non-intensive" management (Fisk 1986). USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 131 Even after the injunction was in place stopping the project, Sequoia National Forest continued with the site preparation and planting. During the course of site preparation, many smaller giant sequoias, up to eight inches in diameter (some 60 years old), were accidentally cut, piled, and burned. These stumps are evidence that the grove was indeed regenerating itself before the "treatment," and evidence that young sequoia reproduction was not a priority to Sequoia National Forest. While the contract provided for penalties for damaging any giant sequoia, Sequoia National Forest did not penalize the industry for cutting these trees, explaining, "The original Environmental Analysis Report ... designated the protection of specimen `reserve' giant sequoia trees. Because of the fact that the giant sequoias cut were not of specimen 'reserve' size as defined in the original Environmental Analysis and not designated as reserve trees as indicated in C2.3# Reserve Trees in the timber contract no action was taken" (Crates 1989). Land Management Plan After the injunction was in place, and Sequoia National Forest was clearly aware of public sentiment favoring grove preservation, the Land Management Plan, issued in 1988, called for similar treatment of 9,300 acres of giant sequoia groves. The Sierra Club and others appealed the Land Management Plan on this and other issues. As late as 1990, Environmental Assessments were listing the goals to "manage groves with objectives of perpetuating the species, preserving old-growth specimen trees, and providing timber." Please note that throughout all the controversy, no one has suggested that there is a shortage of individual giant sequoia trees; the concern has been for the natural processes of the ecological entity called a "grove." Persuading the Forest Service to protect "groves" instead of merely protecting unique large specimen trees while doing tree-farm management around them has been a continuing battle. Settlement Agreement The July 1990 Settlement of the Sierra Club's administrative appeal (McDonald 1988) of Sequoia National Forest's Land Management Plan calls for an amendment to the Forest Plan which would manage most groves for preservation of natural processes. The Settlement takes the majority of grove acres out of the "suitable timber base," but logging is allowed in groves to remove fuel loads which might pose a fire threat. To some environmentalists, this language is too similar to some of the arguments justifying recent harsh logging. Another of the Settlement Agreement's weaknesses is that its definition of "grove" does not take into account those environmental factors upon which the groves may depend. It defines groves as small, unconnected islands with narrow buffers; Settlement provisions call for placing grove boundaries 500 feet from the outermost sequoia. In many cases this 132 will be insufficient for long-term protection. For example actions far above groves can interrupt or change surface and/ or subterranean water flow upon which the groves depend. The Settlement is also deficient because it does not require that all sequoias be in a grove; it allows for "naturally occurring giant sequoias outside of groves." Another failing of the Settlement Agreement is that it allows logging in the historical Converse Basin Grove. Remember, the giant sequoia provisions of the Settlement Agreement were not based on scientific grove biology. The Settlement was a compromise bargained between environmental groups, the Forest Service, and the timber industry. Proposals made during negotiations were screened by first running them through the computer to check how they would affect logging volumes. Even should the Settlement Agreement provisions be satisfactory, it leads to an amended Forest Plan which will provide protection by Forest Service policy. Remember the Type I policy which protected the groves and which was changed with so little notice! We may have policy protection once again, but now many of our finest groves are greatly damaged. Local citizens feel that significantly stronger protection is needed, and that the areas to be protected need to be connected and buffered in a large giant sequoia reserve. Enforcement of Policy No projects are supposed to be approved in groves until scientific study has been completed and until specific grove management plans are written. But constant public monitoring is necessary. Last June, a timber sale was sold and even marked on the ground within the Alder Creek Grove (Tule Helicopter Sale 1991). This past April a supposed hazard tree removal project in the McIntyre Grove (USDA 1992) resulted in the logging of several non-hazard trees (Key 1992) with much unnecessary bulldozing; while investigating that sale, we found that other areas of the grove had been logged and bulldozed in the 1990 Nelson Tractor Sale. Many salvage timber sale boundaries take in portions of giant sequoia groves; while decisions state that no logging will occur in groves, there are no indications of grove boundaries on sale maps so grove intrusion is quite possible. Problems in the Logged Groves Giant sequoia grove ecologists need to take a hard look at the recently logged groves. While studies and surveys of groves will cost money, it is important to note that the timber sales within the groves cost taxpayers hundreds of thousands of dollars more to administer and reforest than the income received for the logged timber. If fuel load reduction had been the prime purpose of all the logging, a much more cost effective way for achieving that purpose could have been found (O'Toole 1988). Potential problems exist in these logged groves which may need remediation in the near future. One evident problem is that many of the specimen sequoias had trenches dug USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 This 15-acre unit of the Black Mountain Grove, cable logged in 1987, contains the three isolated "specimen" sequoias named "The Three Sisters." The fire set to "broadcast burn" logging slash on the 50 percent slope burned much too hot. around them to protect them from fire during the burning of logging slash. These trenches, some on very steep slopes, act to concentrate the increased water run-off coming down from freshly denuded slopes. Over time many of these huge trees may become undercut, lose their balance and fall over. It is possible that this effect could be mitigated if work is begun soon. Before the lawsuit was settled, Sequoia National Forest replanted 75 percent pine and 25 percent giant sequoia seedlings at 10 by 10 foot spacing up to the drip lines of the remaining giants. The lawsuit settlement required recently logged groves to be restored to natural conditions; that USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 requirement was interpreted to be the planting up to five seedlings of various conifer species in 12 inch circles at 15 by 15 foot spacing up to the drip line of remaining giants. If the growing sites are as good as predicted, soon there will be an overcrowded conifer thicket in all of these groves. Ostensibly, the groves were stripped of their trees to reduce fire hazard, yet in many cases the fire ladder is still in place. And worse than before, at the bottom of the fire ladder, waiting like an incendiary bomb, is the most flammable item in the forest: an even-aged plantation. In established plantations such as in the Alder Creek Grove, it may be too late to initiate a natural-like fire regime; hand 133 This aerial view of logging on Sequoia National Forest shows a clearcut harvest unit in both grove and non-grove areas: the spared giant sequoias in the Long Meadow Grove stand newly vulnerable to the elements in a modified clearcut. thinning may be necessary. In the recently planted groves, a corp of volunteers could relieve the area of excess nonnatural seedlings. In the groves there are many temporary roads, landings, and firebreaks, compacted and pouring increased runoff and sediment into the streams; these need to be restored back to a natural state. Some logging roads cut across subterranean water flow that used to seep across a wide area, sustaining the groves. Now, because the flow has been interrupted by road cuts, the water is collected, channeled into culverts, and 134 concentrated into narrow surface streams. This loss of subsurface water could have catastrophic impacts on the future of certain groves. Many of the groves have cattle grazing in them. The cumulative impacts of grazing need to be studied in addition to all of the other impacts already occurring in the groves. As for the supposed problem of lack of sequoia reproduction, how many recruitment trees are optimum? Many of the Black Mountain sites contain plentiful sequoias in many age classes. This is the same grove that had the smaller Sequoias USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 removed by accident. I believe that short-lived human beings lack perspective when looking at a species that can live 3,500 years and still be fertile. Even one recruitment per acre every century might be too many if you consider that other tree species also grow in a natural grove. While it is certain that fire has a natural role in all areas of the Sierra, certainly some grove areas did not burn for extended periods of time, perhaps even several hundred years. The trees targeted for recent logging from groves were old-growth pine ranging from 150 to 350 years of age (stump evidence). As for recent logging emulating fire, it is difficult to imagine a natural fire regime which would totally consume the ancient pines and leave the giant sequoias intact. If the recent logging emulated fire in any way, there should have been no need to artificially replant sequoia; clearly, despite agency rhetoric, the replanting of pine was not intended to imitate nature. We need to change the timber production mentality which refers to stocking standards; a natural grove in most cases does not consist of pure sequoia, but rather is a mixed-conifer forest with a diversity of age classes. In a natural grove there are some areas which do not contain sequoias, perhaps even for centuries; we must enlarge our vision in order to understand a species which exceeds our concept of time. Probably the greatest threat to the groves involves the continuous degradation and fragmentation of the adjacent forests. While the Settlement Agreement calls for some constraints on logging, and while recent studies on the plight of old-growth dependent species are calling for a reduction of clearcutting and logging volumes, Sequoia's timber program, to date, appears to be unchanged. Sequoia National Forest's Five Year Sale Plan shows a continuation of what local involved citizens believe is an unsustainable and destructive amount of logging and clearcutting. The Future The giant sequoia tries human beings' lack of patience and humility; as so many have noted, in our short lifetimes we cannot know but a small portion of the sequoia story. It may be centuries before the consequences of this generation's actions can be evaluated. In the past century and a half nearly every impact imaginable, from subdivisions to clearcuts, has occurred in one grove or another. The few groves or portions of groves that have been spared must, to the greatest extent possible, have minimum intrusion. As long as a grove contains seed bearing trees, there will be options. The danger is not in doing too little, but in doing too much. Not only do scientists need the remaining untouched groves for baseline comparison, we must not foreclose the options of future generations who will better understand Sequoia ecology. We must continue to gather information about this fascinating species and trust that our children and their children will value these magnificent creations, build upon our knowledge, and continue our work. I urge all who study and love giant sequoias to visit and hike in the forest and see how it is being managed. Defend USDA Forest Service Gen. Tech. Rep. PSW-151. 1994 these places, refuse to let research findings be misapplied, and don't trust agencies to always do the right thing. Tell Congress that the natural world matters to you; indeed we cannot exist without it. Tell them that the sequoia groves will be safe only if the entire forest which sustains them is healthy. Insist on legislative protection for a generous reserve connecting and buffering the groves. My favorite giant sequoia is the Wishbone Tree in the Wheel Meadow Grove. I first met it when I was about five years old. As sequoias go, it's not terribly big, but it looks like a wishbone because of the opening at its base. The trail goes through that opening, and I can ride my horse through without ducking my head. The tradition is that as you pass through the tree you touch it and make a wish. Today, instead of my former teenage wishes for fame or fortune, my wish is much more serious; it is for life on earth to continue; it is a wish that countless future generations of children will be able to reach out and touch this tree with wonder and awe as they make their own wishes.
