A Railroad Crossing Outside of Hazen, Nevada oil on canvas 16 1/16 x 36 1/8 inches 2008 |
Although it had been green across most of the state, many
low-lying areas remain barren even in years of abundance. All of us have seen or heard how deserts
bloom after rain showers. That happens
here as well, but not as often as it does in Texas
or New Mexico . It is not only a matter of it being dryer; it
is also due to the timing of the rainy season.
The monsoons of the desert Southwest arrive in summer. In much of the Great
Basin , precipitation falls as snow when plants are dormant. Because most of Nevada has no drainage,
snowmelt stands in low-lying areas awaiting evaporation, saturating soils with
mineral salts that never make the sea.
The soils are toxic to an awful lot of plants, including many weeds.
I wonder how so many of the world’s plants came to be
weeds. Until recently, anything native
qualified, and juniper are still thought to be in need of clearing. Nevada
is said to have had vast grasslands when the cattle arrived; the sea of sage is
explained as overgrazing. At Great Basin National Park , displays say the
landscape is new due to fire prevention.
From driving around, I agree that northern Nevada was mostly grassland, but the pinion
and juniper that drape mountainsides along US Highway 50 have been there for a
very long time. That can be a problem
with scholarship. Historical documents talk
about vast grasslands and some assume that applies to the entire state. Early travelers followed the Humboldt River where mountains and hills are simply sage. It is a mistake to extend that description to
other ranges of the region. If the Snake Range
was not thick with juniper and pinion pine 100 years ago, where did the
evergreen abundance come from? It takes
hundreds of years to grow trees of any size in the dry climate. Count the tree rings; fires were not
routinely roaring through the forests.
There are some parts of the country, where burning the undergrowth
is the same thing as burning up trees. Nevada is not a land of towering pines like Florida or northern California . The brush cannot be burned without torching
the oak, juniper and pinion pine. The
many fires have more to do with climate change than unwise fire suppression. When you go from three dry years in ten, to
seven, fire becomes reality.
Suppressing fire with fire promotes grass, as any rancher
knows. A few years ago, a ridge burned not far from
my parents’ house. Before the fire, the
flat was open, and most of the oak and juniper grew along the hillsides. It was lichen-covered rock, dwarf sage,
wildflowers and very little grass. The quick
burning fuel that drives wildfires was in short supply. Afterwards, golden waves of grass tumbled
into the woods waiting to be thunderstruck.
Instead of quelling the threat, it is raring to explode. That might be why ranges that burn keep
catching fire.
