Four Important Reasons Why We Need Natural Open Space
By Rick LoBello

January 13, 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.

Largest urban park in the US threatened by urban sprawl
by Rick LoBello

December 5, 2010. The Texas Parks and Wildlife Department protects the heart of the Franklin Mountains range as part of the country’s largest urban park, Franklin Mountains State Park. One of the greatest challenges in protecting the park and its biodiversity is the ongoing destruction of the desert by urban sprawl developments in the surrounding lowland desert habitat. Over the past 100 years nearly the entire foothills natural landscape has been destroyed by developments from the historic Rio Grande and the downtown area for nearly 10 miles north towards New Mexico on both the east and west sides of the range.
The Franklin Mountains Wilderness Coalition has a grassroots effort underway to protect Public Service Board administered public lands as natural open space along the west side of the range along Trans Mountain Road and the Fort Bliss Castner Range in northeast El Paso. On October 6, 2010 the El Paso City Council voted to direct city staff to rezone 900 acres included in the Northwest Master Plan near the boundary of Franklin Mountains State Park so that they cannot be developed.

The El Paso Water Utilities Public Service Board, of which the Mayor of El Paso is a member, passed a resolution stating they would pursue all available remedies of law in response to the City Councils action because of their concern that rezoning the land could kill a $80 million highway project in the same area which along with housing developments will end up destroying the last remaining wild and scenic corridor in this part of the Franklin Mountains. The PSB believes that there is no cause for concern highlighting how they have been proactive in protecting the mountains including the transfer of “nearly 8,000 acres to expand the Franklin Mountains State Park.” They also state that there is no mountainside development in the Northwest Master Plan; it’s all on the hillside lower elevation areas and that they are” leaving open space as a buffer between development and the state park.”  The issue was addressed again by City Planning Commission on November 18 when they voted unanimously not to recommend rezoning the Scenic Transmountain Corridor as Natural Open Space.

Many people in El Paso believe that if current efforts to protect the lower elevations of the Franklin Mountains fail the City of El Paso will be hard pressed to live up to an important goal in its Sustainability Plan adopted on September 15, 2009 to “achieve international recognition for successful preservation of our Chihuahuan desert heritage for all time” and many species that depend on these lowland areas will be displaced or die when their habitat is destroyed.

Most biologists familiar with the Chihuahuan Desert understand the importance of protecting all elevations of the eco-region, not just the rugged mountain slopes and peaks. In El Paso many believe that as long as you protect the mountain vistas and have a park like Franklin Mountains State Park protecting 37 square miles of the higher elevations, protection of lower elevations is not a concern. This misconception if far from the truth since many desert species of animals and plants survive only in lower elevations while others with large home ranges need habitat at more than one elevation. For example, in the City of El Paso burrowing owls appear to be declining in numbers because of all the new housing developments being constructed across the city. These owls require low elevation areas where they can nest underground in abandoned burrows dug by mammals or if soil conditions allow in burrows they dig themselves.

In northeast El Paso the Franklin Mountains Wilderness Coalition is partnering with the Frontera Land Alliance to protect the Castner Range at Fort Bliss. To help call attention to the importance of protecting this area from proposed developments the Coalition since 2007 has been sponsoring an annual Poppies Celebration in March on the grounds of the El Paso Museum of Archaeology in the heart of the Castner Range. The area is well known as one of the best spots to enjoy the Mexican poppies that bloom in this area.

Last year Congressman Silvestre Reyes secured funding from the Appropriations Bills in the amount of $300,000 to fund a Castner Range Conservation Conveyance Study aimed at preserving Castner Range for conservation purposes. This study will facilitate a conservation conveyance which is a first step for transferring responsibility of 11 square mile Castner Range to the State of Texas. This project will help preserve open space in the El Paso area and supports efforts to expand the Franklin Mountains State Park.
Achieving successful preservation of the Chihuahuan Desert within city limits and the surrounding region with the help of researchers and conservation educators will require the commitment of a wide range of stakeholders including City and County land management authorities, Texas and New Mexico state governments, private landowners and the surrounding community.

There are many reasons why protecting El Paso's Trans Mountain Scenic Corridor is so important to protecting Franklin Mountains State Park. Here are ten of them.

1. The lowland desert areas surrounding Franklin Mountains State Park provide habitat for many species of animals and plants. To survive in this part of the Chihuahuan Desert ecoregion many species require these lower elevations for food and protection. Other species require habitat at both low and high elevations.

2. As urban sprawl creeps closer to the boundaries of the park the area's nesting birds will be threatened by domestic cats that many people in El Paso allow to roam freely in their neighborhoods.

3. The new TX-Dot road project and related developments along the three mile corridor on the west side of Trans Mountain Road will destroy the last wild scenic view in this part of the city important to the quality of life for thousands of El Pasoans currently enjoying the area.

4. The loss of the last wild scenic view in West El Paso will hurt the city's ability to expand ecotourism important to the entire region.

5. Campers visiting the Tom Mays section of Franklin Mountains State Park plus those who will someday be able to camp out on backcountry trails will be affected by both light and noise pollution associated with developments included in the Northwest Master Plan.

6. Threatened Texas horned lizards living in the lowland areas of the Franklin Mountains will lose critical habitat which could eventually lead to extinction of the species in this part of Texas.

7. Golden eagles and other raptors in the Franklin Mountains will lose important lowland hunting and nesting areas.

8. Mule deer will not have as many lowland areas to use as part of their overall range important to seasonal food production and protection from extreme temperatures during winter snow storms.

9. Javelina or collared peccaries appear to be expanding their range in this area and developments associated with the Northwest Master Plan will hurt their chances of finding the habitat they need to successfully establish themselves in this part of El Paso.

10. The potential for any future efforts to restore extirpated species like desert bighorn and Mexican wolves to this part of the Franklin Mountains will be impaired by urban sprawl developments.
