Texas Master Naturalist Program (Part 3 of 3)

Yellow flower, yellow butterfly…the quest begins for
identification and information…books, internet, experts until the
yellow has been named. Native? Beneficial? Is this a common sunflower?
I have been challenged by yellow.

Entities were on the move the second weekend in October. Tarantulas
cross the road, butterflies dart from flower to flower, and vultures
wait for that first cold front. And those of us in the Texas Master
Naturalist class cover ground in Big Bend National Park and Alpine.

This male tarantula (Family Theraphosidae) was in a
determined search for a mate and his fate. If he is not eaten by a
female, he will die a few months after mating.
Don Corrick, BBNP Geologist, led a driving tour from Persimmon Gap
to Panther Junction, unraveling some of the earth’s formation mysteries
and organized the park’s mountains, valleys and flatlands into four
historical chapters while explaining how some of the chapters are
presently being rewritten…how advances in research technology have
added a new theory to the evolvement of Goat Mountain.

Patt Sims (Shafter) on left and Steve Elfring (Alpine)
on right, hold the world for Don Corrick (BBNP) as he explains shifting
masses of lands that were formative to the park’s landscape.
We wandered all over Rio Grande Village and Boquillas Canyon Trail
with Jeffery Bennett, BBNP Hydrologist, while he covered the basics of
aquatic and wetland ecology and the significance of a river’s highs and
lows.

“There is nothing linear to energy, it flows in all
sorts of circles and eddies,” comments Jeffery Bennett (Alpine/BBNP) as
he explains how the river channel has changed in over fifty years.
River regulation has been a factor in eliminating the extremes of
scouring floods and dry, stressful times. This has allowed invasive
plants to move into the flood plain creating a smaller channel and
consequently habitats are altered.
An afternoon of meandering through a substantial archeology site was
spent with Dr. Stephen K. Mbutu, Assistant Director at the Center of
Big Bend Studies in Alpine. As we gawked at rocks, he explained
evidence of human occupation: metates, wickiups, and tools.

Proximity to water, excellent vantage points, and
defensible outcroppings were factors for various cultures to spend time
at the archeology site shared with us by Dr. Stephen K. Mbutu. (L to R)
David Mainz (Ingram), Mary Baxter (Marathon), Dr. Mbutu (Alpine), and
Roger Siglin (Alpine).
Dr. Joe Sirotnak, BBNP Botanist, clarified conflicts with invasive plants in the area. How they arrived, why they are problem, and methods of removing them.
BBNP Wildlife Program Manager Raymond Skiles exhibited methods to
work out conflicts between humans and animals (everything from rodents
in employee housing to mountain lion or bear encounters on the trail)
while giving an overview of the diverse mammalogy in the park.

Hundreds of turkey vultures Cathartes aura were recently
swirling upward over the Rio Grande in formation for migration. We will
herald their return in March.
Our final day was spent driving to Alpine for an enthusiastic
presentation by Dr. Cathryn Hoyt, Executive Director of Chihuahuan
Desert Research Institute, on naturalists from the past including ideas
on how Native Americans studied nature.

“Museums do not teach by rote, but rather by imagination,” states Larry Francell (Fort Davis)
The closing hours of our 40-hour class time were spent with Larry Francell, Director of the Museum of the Big Bend. He stressed the importance of museums and how a child’s wonderment in learning and understanding is the basis for such a foundation. Francell’s ideas were with me recently as I watched a father with his two young sons. We were on a bike tour and had been exploring in a creek. The kids asked why aren’t they fish here? Where did the crystals come from? And as we strolled through a blanket of purple-pink Nama flowers, the father said “Stop, listen…do you hear that?”
“They’re bees,” the older boy commented. We stood and just listened
to the bees getting ready for winter. Kids are such natural
naturalists.

Tornillo Creek spins its enchantment on Donna Greene (Alpine).

So now our class of adult kids will be deemed Texas Master
Naturalists with 40 hours of volunteer work and 20 hours of continuing
education. We’ve been informed of many volunteer options so you’ll
probably see us out there helping Bennett and Sirotnak replacing native
plants near the Boquillas Canyon entrance, or clearing brush on Fort
Davis Nature Conservancy land, or cleaning congested waterways of
invasive plants at Elephant Mountain Wildlife Management Area.
