The so-called cedar of the Texas Hill Country, actually a true juniper,
Juniperus
ashei, has been called a weed, allergen, invader, nurse-tree, building
material, allelopath and not too long ago, crucial component in the life
of the Golden-Cheeked Warbler. It is all that and more.
Ashe Junipers have grown on the picturesque hills of central Texas for
many thousands of years. Their range has not changed appreciably,
their density, however, has. Whereas they were originally restricted
to the steeper sites, they now occupy vast areas which were once a prairie.
That prairie was a fire climax flora. Fires, set by lightning or
native Americans, killed the woody invaders but rejuvenated the grasses
and broad-leafed plants of the prairie matrix.
When the prairies of the Hill Country were overgrazed in the mid to latter
years of the nineteenth century, that beneficial cycle of fires was broken.
Oaks, Cedar Elms and Ashe Junipers soon invaded lands where grazing animals
and deer were the only check on their growth.
Those who are restoring the prairies of the Hill Country, either for sustainable
ranching activities or because they wish to heal a wound man has caused,
have my admiration. Prairies are beautiful, especially at dawn and
dusk. Their charms, except in the peak of spring bloom, are subtle.
I revel in their broad sweep as well as in their smallest details.
However, I do not want to extirpate all Ashe Junipers. A scene of
ancient ones with massive, fluted trunks clothed with shaggy, aromatic
bark, seeming to flow out of vertical limestone canyon walls, is also worth
preserving. That is their prime habitat. They have been growing
there for millennia. They are not out-of-place on those craggy slopes.
They are certainly out-of-place and unwelcomed on gentle slopes and level
fields.
Media-savvy environmentalists, when they try to appeal to the public, use
a few basic images. One is of cute, cuddly animals. They refer
to them as "critters" in their press releases and staged events.
One witty observer called their poster animals, the "charismatic megafauna".
Another icon is "old growth". It is a powerful and evocative image
for a society surrounded by the ephemeral and the disposable.
Wilderness was the catchword of the seventies. Old growth took its
place in the nineties. The manipulated masses, and especially children
in government schools, have come to believe that preserving some acres
of old growth here and a hillside of old growth there will actually make
a difference.
With the over-used and malleable tool that is the Endangered Species Act,
the environmentalist's agenda of protecting ecosystems from any development
(and not having to personally pay to set aside such lands) has gained much
territory as well as ill will. The case of the Northern Spotted Owl
is illustrative. A creative taxonomist, saw within the Spotted Owl,
a species known to range from British Columbia to Baja California, a brand
new subspecies. He named it the "Northern Spotted Owl" and conveniently
limited its range to the old growth forests of gigantic Douglas Firs of
the Pacific Northwest.
That designation and subsequent listing of the bird as an endangered species
caused severe economic dislocations. Scientists now know the bird
is not that choosy in its habitat requirements. It is regularly seen
in forests logged and re-planted in the last century. The scientific
fraud of identifying a new subspecies and claiming it had a restricted
range is still causing problems.
Closer to home, environmentalists have claimed a bird which spends only
five months of the year in Texas, and seven months in Mexico and Central
America, is endangered and is, it seems, restricted to Juniper/Oak woodland
old growth. Ornithologists have stated the bird, to build its nests,
must have, "exceedingly old juniper trees", to obtain, "long strips of
Ashe Juniper bark."
In Warren M. Pulich's 172-page study of the Golden-Cheeked Warbler, we
learn that 78.91 % of a nest, by weight, is strips of cedar bark.
But, 24.49 % is strips 0.79 to 1.18 inches long, 29.93 % is strips 1.18
to 3.15 inches long, 18.37 % is strips 3.15 to 4.33 inches long and the
remaining 6.12 % is strips 3.94 or more inches long.
Strips of such "great length" can be found even on very young junipers.
In fact, in the Recovery Plan for the bird, which represents the official
position of the U. S. Fish and Wildlife Service, we read that, "Female
warblers have been observed obtaining bark strips for nest building from
Ashe Junipers with diameters at breast height as small as 7.5 cm", that
is only 2.95 inches!
Is a three-inch-caliper tree worth of being called "old growth"?
Facts do not support the contention that old growth junipers are a prime
habitat requirement of that migratory songbird. Yet, voodoo science
is being used to limit what men may do with their plants on their private
property. It is a low point in the saga of plants and man.
