The goal of park management in the

Item 1 in the report just quoted specifies that "a
prior definition of the purposes and objectives of each park is
assumed." In other words. the goal must first be defined.
As a primary goal, we would recommend that the biotic
associations within each park be maintained, or where necessary
recreated, as nearly as possible in the condition that prevailed when
the area was first visited by the white man. A national park should
represent a vignette of primitive America.
The implications of this seemingly simple aspiration
are stupendous. Many of our national parks -- in fact most of them --
went through periods of indiscriminate logging, burning, livestock
grazing, hunting and predator control. Then they entered the park system
and shifted abruptly to a regime of equally unnatural protection from
lightning fires, from insect outbreaks, absence of natural controls of
ungulates, and in some areas elimination of normal fluctuations in water
levels. Exotic vertebrates, insects, plants, and plant diseases have
inadvertently been introduced. And of course lastly there is the factor
of human use -- of roads and trampling and camp grounds and pack stock.
The resultant biotic associations in many of our parks are artifacts,
pure and simple. They represent a complex ecologic history but they do
not necessarily represent primitive America.
Restoring the primitive scene is not done easily nor
can it be done completely. Some species are extinct. Given time, an
eastern hardwood forest can be regrown to maturity but the chestnut will
be missing and so will the roar of pigeon wings. The colorful drapanid
finches are not to be heard again in the lowland forests of Hawaii, nor
will the jack-hammer of the ivory-bill ring in southern swamps. The wolf
and grizzly bear cannot readily be reintroduced into ranching
communities, and the factor of human use of the parks is subject only to
regulation, not elimination. Exotic plants, animals, and diseases are
here to stay. All these limitations we fully realize. Yet, if the goal
cannot be fully achieved it can be approached. A reasonable illusion of
primitive America could be recreated, using the utmost in skill,
judgment, and ecologic sensitivity. This in our opinion should be the
objective of every national park and monument.
To illustrate the goal more specifically, let us cite
some cases. A visitor entering Grand Teton National Park from the south
drives across Antelope Flats. But there are no antelope. No one seems to
be asking the question -- why aren't (they) there? If the mountain men
who gathered here in rendezvous fed their squaws on antelope, a 20th
century tourist at least should be able to see a band of these animals.
Finding out what aspect of the range needs rectifying, and doing so,
would appear to be a primary function of park management.
When the forty-niners poured over the Sierra Nevada
into California, those that kept diaries spoke almost to a man of the
wide-spaced columns of mature trees that grew on the lower western slope
in gigantic magnificence. The ground was a grass parkland, in springtime
carpeted with wildflowers. Deer and bears were abundant. Today much of
the west slope is a dog-hair thicket of young pines, white fir, incense
cedar, and mature brush -- a direct function of overprotection from
natural ground fires. Within the four national parks -- Lassen,
Yosemite, Sequoia, and Kings Canyon -- the thickets are even more
impenetrable than elsewhere. Not only is this accumulation of fuel
dangerous to the giant sequoias and other mature trees but the animal
life is meager, wildflowers are sparse, and to some at least the
vegetative tangle is depressing, not uplifting. Is it possible that the
primitive open forest could be restored, at least on a local scale? And
if so, how? We cannot offer an answer. But we are posing a question to
which there should be an answer of immense concern to the National Park
Service.
The scarcity of bighorn sheep in the Sierra Nevada
represents another type of management problem. Though they have been
effectively protected for nearly half a century, there are fewer than
400 bighorns in the Sierra. Two-thirds of them are found in summer along
the crest which lies within the eastern border of Sequoia and Kings
Canyon National Parks. Obviously, there is some shortcoming of habitat
that precludes further increase in the population. The high country is
still recovering slowly from the devastation of early domestic sheep
grazing so graphically described by John Muir. But the present
limitation may not be in the high summer range at all but rather along
the eastern slope of the Sierra where the bighorns winter on lands in
the jurisdiction of the Forest Service. These areas are grazed in summer
by domestic livestock and large numbers of mule deer, and it is possible
that such competitive use is adversely affecting the bighorns. It would
seem to us that the National Park Service might well take the lead in
studying this problem and in formulating cooperative management plans
with other agencies even though the management problem lies outside the
park boundary. The goal, after all, is to restore the Sierra bighorn. If
restoration is achieved in the Sequoia-Kings Canyon region, there might
follow a program of reintroduction and restoration of bighorns in
Yosemite and Lassen National Parks, and Lava Beds National Monument,
within which areas this magnificent native animal is presently extinct.
We hope that these examples clarify what we mean by
the goal of park management.
