Chapter 4
The Rise and Decline of Ecological
Attitudes, 19291940 (continued)
Forests
As with fish, the management of national park forests in the 1930s
continued established practices. But the forestry policies were strongly
challenged by the wildlife biologists. The conflict over forestry
practices exposed fundamental differences between the biologists and
much of the rest of the Park Service. The failure of the biologists'
challenge to forest management demonstrated the weakness of their
position within a traditional organization and, conversely, the
considerable bureaucratic strength that the foresters were gaining.
National park forestry operations expanded tremendously during the
New Deal, receiving far more funds and support from the emergency relief
programs than any other natural resource management activity in the
parks. The 1933 act creating the Civilian Conservation Corps
specifically called for protection of the nation's forests from fires,
insects, and disease damagegoals that matched perfectly those of
most national park managers. So important did forestry become in the
overall work of the CCC that the organization was at times referred to
as Roosevelt's Tree Army. [113]
In his 1933 annual report, Horace Albright's comments on the initial
work of the CCC foreshadowed the tremendous expansion of national park
forestry. The director stated that the newly established CCC crews were
accomplishing "work that had been needed greatly for years," but that
had been "impossible" under ordinary appropriations.
Especially has the fire hazard been reduced and the appearance of
forest stands greatly improved by cleanup work along many miles of park
highways; many areas of unsightly burns have been cleared; miles of fire
trails and truck trails have been constructed for the protection of the
park forests and excellent work accomplished in insect control and
blister-rust control and in other lines of forest protection;
improvements have been made in the construction and development of
telephone lines, fire lookouts, and guard cabins; and landscaping and
erosion control [have] been undertaken. [114]
During the buildup of CCC-funded forestry programs in 1933, Director
Cammerer designated John Coffman the Service's "chief forester," in
charge of the newly created Division of Forestry, now separate from the
Service's educational program. [115] The
forestry management policies that Coffman and Ansel Hall had prepared
provided guidance for the Park Service throughout the decade. Under
these policies the forests were to be "as completely protected as
possible" against fire, insects, fungi, and "grazing by domestic
animals," among other threats. This comprehensive protection was to be
extended to "all park areas" associated with "brush, grass, or
other cover." [116] Backed by new policies
and staffed by thousands of CCC enrollees, Coffman's forestry programs
became an increasingly important force in national park operations
during the New Deal era.
Significantly, although the Park Service had begun building a cadre
of wildlife biologists, the bureau did not hire plant biologists or
botanists per se. Rather, it hired "foresters," who were deeply
influenced by the management practices of the U.S. Forest Service,
particularly regarding control of forest fires, insects, and disease.
With the foresters maintaining such traditional attitudes, the wildlife
biologists were left with few allies to argue the case for ecological
management in the parks. Central to the biologists' concerns were the
various prefire protection activitiesthe very kinds of development
Albright enthusiastically endorsed. They objected to building fire roads
through natural areas and clearing hazardous dead trees and snags that
contributed to the fuel buildup and increased the possibility of
fire.
Indeed, the wildlife biologists were never in agreement with the
forest management policies written by Coffman and Hall. Although forests
were not the focus of George Wright's initial wildlife survey,
preserving natural habitat, including plants, was recognized as
fundamental to successful park management. In contradiction to ongoing
Park Service forestry practices, Fauna No. 1 urged that park forests not
be manipulated, stating, for instance, that "it is necessary that the
trees be left to accumulate dead limbs and rot in the trunks; [and] that
the forest floor become littered." [117]
Nevertheless, the CCC programs provided funds and manpower for extensive
clearing of forest underbrush and dead trees. This work increasingly
alarmed the biologists.
Roadside clearing, a widespread practice in national parks, was
intended as a fire protection measure but, in the words of a Park
Service manual, was equally important as a means "to improve the
appearance of the immediate landscape of the main drive" through parks.
A conflicting view came from Wright, who wrote Director Cammerer early
in 1934 of the need to consider "all sides of the question" regarding
clearing of hazardous debris along park roadsides, including the concern
for "wild life values." Wright realized that clearing dead limbs and
trees affected habitat. He urged that the Service "reconsider" and
determine "exactly under what conditions and in what parks roadside
clean-up is a benefit and to what extent it should be carried on." He
also told Cammerer that the biologists had discussed the issue with park
superintendents and rangers, and that there was "anything but unanimity
of opinion on the value of this work." Although some superintendents and
rangers recognized the impact on natural conditions, others believed
cleanup did not help prevent fires. [118]
Nevertheless, clearing was widely accepted in the Service and remained a
common practice in the parks.
An opinion even stronger than Wright's came from Adolph Murie in the
summer of 1935, during an extended debate over whether or not to clear a
twelve-square-mile area on Glacier National Park's west slope, just
north of McDonald Creek, a forested area damaged in a recent fire. With
many of the trees only partially burned, the tract seemed ripe for
another fire, which could spread to adjacent, unburned forests. A
meeting in the park in July provoked disagreement on the propriety of
cutting and removing all of the dead trees, whether standing or fallen.
The contentious debate reflected sharp divergence between the wildlife
biologists and the foresters on fire protection and overall national
park policy.
Following the meeting in Glacier, Murie reported to the Wildlife
Division in Washington his intense opposition to the proposed clearing.
In a lengthy letter, he wrote that the burned area was still in a
natural condition and questioned the desirability of "removing a natural
habitat from a national park." Requiring roads for trucks, bulldozers,
and other equipment, the clearing operation would cause "gross
destruction," which, he believed, would interfere with the normal cycles
of forest decay and growth and create instead a "highly artificial
appearance of logged-off lands." Removal of the trees would reduce the
area's organic material and its soil fertility, and would cause drying
of the soil and increased erosion.
Moreover, Murie argued, this large clearing project could be used to
justify "almost any kind of landscape manipulation" in the future. "For
what purposes," he asked, "do we deem it proper to destroy a natural
state?" His answer was that almost no purpose justified such
destruction. Murie concluded his argument with an opinion surely unheard
of in national park management before the wildlife biologists began
their work under George Wright: "To those interested in preserving
wilderness, destroying a natural condition in a burn is just as
sacrilegious as destroying a green forest. The dead forest which it is
proposed to destroy is the forest we should set out to protect." [119]
Murie's remarks were quickly challenged. Lawrence F. Cook, head of
John Coffman's forestry operations in the western parks, had also
attended the meeting in Glacier. Cook found Murie's report "rather
typical" and took a directly opposite position, fearing the long-term
loss of green forests. "Nature," he commented, "goes to extremes if left
alone." Despite the Service's best protection efforts, "gross
destruction" had resulted from the fire. Beyond adequate detection, fire
protection depended on "easy access" into the forests and the "reduction
of potential fuel" through clearing both of which would result
from the proposed work in Glacier. Cook anticipated a rapid recovery of
forest growth, but only if the area were cleared of dead trees so it
would not be burned over by another, more damaging fire. Seeking to
protect the beauty of the forests, he also recognized that this part of
Glacier was intensively used; it was seen, he claimed, "by more
travellers than any other in the park." Cook argued that the question
was not whether to allow nature to take its course in the national
parks, but to what extent the Service "must modify conditions to retain
as nearly a natural forest condition as possible for the enjoyment of
future generations." [120]
In a separate memorandum to Coffman, written the same day, Cook
expressed concern that the Service's foresters had been accused of being
"destroyers of the natural." Their construction of truck trails and fire
lookouts and their clearing of damaged forests had been criticized not
only by the biologists but by some superintendents, rangers, and
landscape architects. Cook insisted that the foresters were seeking to
preserve the "natural values" of the parks, while also providing for the
"greatest use and enjoyment of the parks with the least destruction." He
summed up his credo of national park management, and fire protection in
particular: "The parks have long since passed the time when nature can
be left to itself to take care of the area. Man has already and will
continue to affect the natural conditions of the areas, and it is just
as much a part of the Service Policy to provide for their enjoyment as
it is to preserve the natural conditions. There is no longer any such
thing as a balance of nature in our parksman has modified it. We
must carry on a policy of compensatory management of the areas." He
added that "forest protection" is a "very necessary part of this
management." Without protection the Service faced the destruction of
"any semblance of biological balance, and scenic or recreational values,
as well as the forests with which we are charged." Certainly Cook's
views prevailed within the Service, and CCC crews cleared a vast area of
the McDonald Creek drainage (such that even today, as a veteran Glacier
biologist put it, negative effects "are still very evident on the
land"). [121]
In truth, the Park Service's biologists and foresters all claimed
they were seeking to preserve "natural values," which would allow for
the "greatest use and enjoyment of the parks with the least
destruction." But the two groups had fundamentally different perceptions
of what constituted "natural values" and what constituted "destruction"
in national parks. Adolph Murie opposed the extensive alterations that
resulted from the Service's fire protection methods employed before,
during, and after fires. His letter on the proposed clearing in Glacier
concluded: "My feeling concerning any of this manipulation is that no
national park should bear the artificial imprint of any man's action of
this sort. We have been asked to keep things natural; let us try to do
so." But Cook's philosophy of national park management reflected the
official forestry policies; with funds and manpower coming from the CCC
program, the Service continued its intensive protection and suppression
activities, rejecting Murie's concepts. [122]
The conflicting approaches to national park management were
evidenced in disagreements over other aspects of forestry. Continuing
the practices of the Mather era as affirmed in the forest policies, both
Albright and Cammerer supported aggressive war against forest insects
and disease, regularly calling on the Bureau of Entomology and the
Bureau of Plant Industry for expert assistance. In his last annual
report (1933), Director Albright noted that "successful campaigns" had
been waged against insects in park forests, ending or reducing several
major epidemics. The Service, he added, had sought to eradicate
infestations of the bark beetle in Yosemite and Crater Lake, and the
mountain-pine beetle in Sequoia National Park. Both Glacier and
Yellowstone faced insect infestations of such magnitude that studies
were being made to determine if control efforts were even practicable.
It seemed to Albright that the forests in the national parks were truly
under siege from insects, as well as from disease. Among many threats,
blister rust was "spreading rapidly," threatening the western parks.
"Unless checked," Albright warned, it was "only a matter of time" before
blister rust would invade the white pine forests of Glacier and the
sugar and white pines of the California parks. [123]
As with fire protection, the CCC provided the Park Service with
funds and manpower to wage intensive campaigns against forest insects
and disease. Again the wildlife biologists challenged these efforts.
George Wright wrote to Director Cammerer in August 1935 favoring use of
the New Deal work relief programs, but cautioned against too much "zeal
for accomplishment," particularly in insect and disease control.
Generally the biologists accepted limited control in and around park
development, directing their criticism toward more widespread control
efforts. Wright would largely confine control to "heavily utilized
areas" most frequented by visitors. The piñon pine scale
infection in Colorado National Monument was, he pointed out, a natural
phenomenon that seemed "best to leave undisturbed" outside developed
areas. Similarly, reporting on CCC work in Grand Canyon during 1935,
Victor Cahalane commented that the Wildlife Division "disapproves of
insect control, outside of developed areas," unless a native plant was
threatened with extinction. [124]
Much more critical, Adolph Murie lashed out at Park Service insect
and disease control efforts after a 1935 visit to Mount Rainier. He
acknowledged to Wright that "possibly some effort" was necessary to save
"certain outstanding forests." But he opposed extensive control,
emphasizing that in its forest management the Service should not "play
nursemaid more than is essential." Especially alarming were efforts to
kill off native beetle populations and to control the blister rust
disease by eradicating ribes (native currants and gooseberries,
which serve as an alternative host to the blister rust fungus). With
both ribes and beetles native to the parks, Murie urged leaving
them alone and "permitting natural events to take their course. . . .
The cure is about as bad as the disease." Ribes was, in his
words, "just as desirable in the flora as is pine," and he concluded
that "justification for destroying a species in an area should be
overwhelming before any action is taken." [125]
Predictably, arguments such as Murie's did not sway the foresters.
In his letters to Coffman on fire management, Lawrence Cook rebutted the
biologists' position, defending the Service's forest disease and insect
control policies as an essential part of park management. As with fire
suppression, the foresters believed that "some modification," including
insect control, "is necessary to preserve for the future the living
values of the parks." And, indeed, aggressive forest insect and disease
control continued while CCC money and manpower were available. Late in
the decade Director Cammerer reported on blister rust control and beetle
eradication in a number of parks, noting the support of the Bureau of
Entomology and dependence on the CCC program. [126] The termination of the CCC just after
World War II began would drastically reduce the resources available to
the Park Service for control workbut the policies remained in
force, waiting for postwar funding.
The wildlife biologists had found a voice in national park policy and
operations, but they frequently clashed with the foresters, who
continued their practices despite the biologists' objections. Decades
later Lowell Sumner reflected that "even George Wright was unable to
make much progress" in establishing ecologically sound forest
management. [127] The biologists' criticism
of various forest practices had little effect on Service policies, a
reflection of the support the foresters enjoyed from Park Service
leadership. The policies on forest fires, insects, and disease were
aimed at maintaining the beauty of the parks and enhancing public
enjoyment, and were much more in line with mainstream national park
thinking than were many of the ideas of the wildlife biologists.
In 1940, at the end of Cammerer's directorship and with the
biologists' influence in decline, the foresters were truly in the
ascendancy. The Park Service's official organizational chart, revised in
mid-1941 (a year and a half after Interior secretary Ickes transferred
the wildlife biologists to the Bureau of Biological Survey), showed the
Branch of Forestry with no less than three divisions: Tree Preservation,
Protection and Personnel Training, and Administration and General
Forestry. [128] Also, foresters entering
the Park Service continued to be influenced by the U.S. Forest Service.
Many national park rangers who did not have the specific title of
forester had nevertheless been schooled in forestry. In addition, the
so-called ranger factory, just beginning at Colorado Agricultural and
Mechanical College in the late 1930s (and which would flourish during
ensuing decades), trained young men to become rangers under a park
management program administered by the forestry school. [129]
Altogether, an alliance was building between the Park Service's
foresters and its rangers (they would be combined organizationally in
the mid-1950s). The influence of this alliance was bolstered by the fact
that the two groups fed directly into leadership positions, in charge of
national park policy and operations. With an increasing number of
forestry graduates attracted to the Service, forestry evolved into one
of the most powerful professions in the organization, attaining full
"green blood" membership in the Park Service family. By the end of the
decade the foresters' bureaucratic strength began to rival that of the
landscape architects and engineers under Thomas Vint and Conrad Wirth.
[130] Although not always in full accord,
these professions, in alliance with the superintendents and rangers,
formed the core of the Service's leadership culture and would dominate
national park philosophy and operations for years to come.
