Four Important Reasons Why We Need Natural Open Space
By Rick LoBello
January 20, 2011. Last year on April 6th I presented to the El Paso City Council a PowerPoint on how Natural Open Space
benefits our community. Helping people understand why we need
to protect our environment is an
important part of my job at the El Paso Zoo. What follows is an updated
summary of my presentation on natural open space.
1.
Natural Open Space helps people enjoy the benefits of the
natural world. Here in El Paso we have
lots of natural open space on the high mountain ridges of the Franklin
Mountains, but little natural open space in the lower elevations immediately
surrounding the mountain range where most people prefer to hike and walk.
Lower elevation natural open space is also critical to many species of plants
and animals that live only in lower elevation habitats or need both lower and
higher elevations areas.
Protecting natural open space is not only a problem in El Paso, but around the
world. To varying degrees humans have already altered nearly half of
the earth’s land surface. If current land development trends continue this
number could easily reach 70% in the next thirty years.
2. The availability of natural open space
helps to prevent nature deficit disorder by giving people more opportunities to
explore the natural world, especially children.
Nature deficit disorder is a growing trend in this country where the average
American child spends 44 hours a week with electronic media.
Effects of Nature Deficit Disorder include: Childhood
obesity, attention disorders and depression and long term ability to cope with
stress and adversity.
3. Natural Open space is important to the water cycle, nature’s ability to
produce oxygen and capture CO2 and other ecological services such as pollination
and the services provided by millions of different species of microbes.
A single tablespoon of healthy soil might contain over a billion beneficial soil
microbes!!! How many microbes live in one acre of natural open space in El Paso is anyone’s
guess. The number is too big for most of us to fathom. Microbes
provide amazingly complex ecological services. These services include
reprocessing materials into available forms (i.e., mineralization) and into
microbial cells and humus. Soil bacteria microbes fix atmospheric nitrogen
and help plants to grow in areas where nitrogen is scarce. Other minerals like
sulfur and phosphorus require microbial transformation in the soil that
surrounds the roots to make them more available to plants. They also
improve aeration by loosening dense and compacted soils.
Most importantly microbes decompose organic waste materials such as leaves and
manure into organic humus. Our desert needs this humus to store both
moisture and nutrients in the soil.
Without healthy soils most plant species could not survive and the entire desert
ecosystem as we know it would likely collapse.
Microbes are also important to balancing soil
acidity and alkalinity, creating the carbon dioxide plants need, as well as
producing vitamins, toxins, and hormones that both feed and protect the plant
system.
Most people looking out across the desert landscape
are not aware of the role microbes play in the desert and or in
their everyday lives. Trying to imagine all
that microbes do for us in
maintaining the ecosystem is like trying to imagine all the stars and galaxies
in the night sky.
4. Natural Open space provides habitat for
thousands of species of animals and plants native to our Chihuahuan Desert and a
part of our natural heritage.
Protecting Natural Open Space and a wide variety of
habitats at all elevations requires
strategic planning designed to
protect these habitats and wildlife corridors important to
species needing to move from one elevation to the next in search of food and
water. Animals also
need natural open space for protection from the powerful rays of the sun, wind
and rain. To adequately raise their young natural open space is needed to
protect many animal species from human disturbance and natural predators.
At this time
strategic plans for the continued development in El Paso and the surrounding
area focus almost solely on the needs of humans and not on the natural
environment. “Smart growth” elements in planning may appear in part to be
green, but do not address the habitat needs of most species of native wildlife
including a careful analysis of wildlife corridors needed to maintain
sustainable populations of larger animals like mule deer, javelina, coyotes,
foxes and bobcats.
We need natural open space because we are connected to the natural world in
countless ways. Every time we allow another acre of natural open space to
be transformed by development activities including urban sprawl, wider roads and
mining, we weaken the ecosystem and its services, all critical to our own
survival.

Big Bend National Park reinstates
temporary closures for Peregrine Falcons
January 20, 2011. In August 1999, the Peregrine falcon was removed from the federal
endangered species list, a move prompted by the falcon’s comeback from the brink
of extinction. However, throughout
Texas
there are less than a dozen
known nesting pairs and the falcon remains on the state’s endangered species
list.
Federal Endangered Species policy requires that Peregrine populations
continue to be monitored. National Park Service policies require the
protection and preservation of all state-listed species and all species of
concern, regardless of federal or state classification. In keeping with
this mandate, and to provide the nesting falcons with areas free of human
disturbance,
Big Bend
National Park
will again
temporarily close or place restrictions on the use of certain park lands.
The areas closed to public entry from February 1 through May
31 are:
The Southeast Rim Trail and a portion of the Northeast Rim
Trail from the Boot Canyon/Southeast Rim junction to a point just north of
Campsite NE-4.
All Southeast Rim campsites as well as Northeast (NE)
campsites 4 and 5 are closed during this period.
Technical rock climbing on rock faces within ¼ mile of known
peregrine eyries, as posted, will not be allowed between February 1 and July 15.
The park does not plan to close any other areas but
restrictions may be modified if Peregrine behavior or nesting sites do not
follow traditional trends.
Through
the efforts of federal, state and private agencies, the Peregrine has staged a
remarkable comeback since it was placed on the federal list in 1970.
Superintendent Bill Wellman remarked, “The small population found in
Big Bend
National Park
and the Rio Grande Wild and
Scenic
River
represents most of the peregrines found in
Texas
.
We appreciate the public support and cooperation that we continue to have for
protecting these remarkable birds."
