The Impending Death of the LRGV

Make no mistake, the construction of a border wall, or even a fence, would doom the economies and ecologies of the Lower Rio Grande Valley LRGV) in south Texas. Public and private lands alike would take the brunt of a closed border, effectively impoverishing every aspect of life in the region. I speak from having visited the area on three separate occasions.

Among our favorite places in Texas is Bentsen-Rio Grande Valley State Park, a world-famous destination for tourists wishing to see birds, butterflies, dragonflies, and other watchable wildlife found nowhere else in the United States. The planned route for the border wall would exclude visitors from half of the current acreage, if the park even remained open to the public at all. This is what the average American does not seem to understand: The rights of American citizens will be denied as a result of this massive undertaking.

The National Butterfly Center, where new U.S. records for Mexican species are documented almost annually, will likewise be heavily compromised, and that is private property. Why Libertarians and others who hold private property in sacred esteem are not up in arms over this is beyond me. There is a lawsuit pending, but it may have little impact, for reasons that should terrify you.

To pave the way for the border wall in the legal sense, executive orders rescinded protections afforded by: The National Environmental Policy Act, the Endangered Species Act, The Federal Water Pollution Control Act (Clean Water Act), The Migratory Bird Treaty Act, The Archeological Resources Protection Act, The Solid Waste Disposal Act, The Historic Sites, Buildings, and Antiquities Act, The National Wildlife Refuge System Administration Act, and The Native American Graves Protection and Repatriation Act, among several other distinguished pieces of legislation (nearly thirty in total) that make this country truly great.

Were it not for persistent and vocal protests, the Santa Ana National Wildlife Refuge would already be bisected by the wall. For now it has received a temporary stay of execution (of wall construction). The refuge is a gem, with a variety of habitats and mind-blowing biodiversity from "bugs" to birds.

A border wall would have a devastating impact on wildlife, for even though birds could fly over the barrier, the habitat would be so fragmented by the structure and accompanying 150-foot "enforcement zone" that migrant wildlife would no longer have refuge in their travels; and resident wildlife would likewise be displaced. Meanwhile, have we learned nothing from the insidious networks of tunnels beneath our existing border barriers? Do we truly believe for an instant that "coyotes" will be deterred from their businesses of human trafficking and gun and drug running?

Opposition to a border wall can take many forms, and you are encouraged to pursue one or more of them:

• Engage in in-person protests at various border locations.
• Call, write, and e-mail your U.S. Representatives and Senators to express your outrage in polite but assertive language.
• Bombard the White House with calls, e-mails, and letters.
• Donate to the National Butterfly Center and other conservation organizations, and humanitarian non-profits that are fighting the border wall.
• Find out who the contractors are for construction of the wall and urge them to cease activity. Threaten to not do business with them otherwise.
• Continue visiting the border and infusing the local economies with your tourist dollars. Ask locals how best you can help them fight the wall.

Our current U.S. President is hell-bent on erecting a highly visible legacy of his own fear of immigrants and refugees instead of enacting foreign and domestic policies that would defuse volatile relations with Mexico and Central America instead of igniting more fires. He insists on punishing law-abiding citizens in the U.S. instead of crafting more stringent laws against human trafficking, and expanding the currently overworked agencies charged with handling the deluge of legitimate refugees seeking asylum.

Foreign policy should address corrupt governments that lead to mass exodus, but we need the cooperation of our allies, the UN, and other international bodies that the President has turned his back on. We may even need more official ports of entry along the border so that the few currently in play are not overwhelmed, and adjacent lands between those posts can be patrolled more easily.

We have by no means exhausted all our options with regard to immigration reform, but we will be taking a step backward by building a wall. Yes, Mr. President, it would be something concrete, literally if not figuratively, but what you personally gain from visibility you will lose by several orders of magnitude in credibility, both at home and abroad.

Resaca de la Palma State Park

The first stop on Bugguide’s “Texas Mini-Gathering” in early June was Resaca de la Palma State Park in Brownsville, Cameron County. The park is only three years old, but at 1200 acres it is the largest park in the World Birding Center contingent of south Texas parks.

Resaca is Spanish for an “oxbow lake,” a wetland cut off from a river that now takes a different path. The wetlands are being restored at Resaca de la Palma, but during the hot, dry season of late spring and summer, water is still scarce. What little water remains does attract a number of water birds such as the Least Grebe shown below.

Our party of three was given the royal treatment from naturalist Katherine Miller and her interns Cynthia and Ryan. We were taken on a tram ride (visualize an electric golf cart built for 8-10 passengers and no clubs) that covers 3.2 miles within the park, stopping anytime we spied something interesting. Cynthia found this spectacular, albeit deceased Beautiful Mesquite Borer, Callona rimosa as we went whizzing by at…about 2 mph.

The visitor center is surrounded by a garden that attracts a dazzling array of butterflies and other insects. One could easily just relax and stake out the bird feeders, too. In the heat and humidity it is a tempting option. Those who do wander the trails will find shade in most places, and be treated to wildlife such as armadillo, lizards, and toads. The trails are certainly used by nocturnal mammals, too, and they leave their, um, calling cards along the way. A pile of scat can be as attractive as a bouquet of flowers, though, as this pair of Mexican Bluewing butterflies attests.

Despite our arrival during the “off season,” the park had no shortage of things to offer and I encourage folks to pay a visit whenever they can. Amenities include eight miles of walking trails, and four wood platforms that each overlook a section of the four-mile Resaca. Watch for active oriole nests (in June at least). Keep an eye out for the large but shy Plain Chachalaca.

You’re likely to hear them more often than you see them. You might also be treated to a display from a Yellow-Crowned Night-Heron.

Many thanks again to Katherine for going out of her way for us (she even escorted us on a night hike). You will never get so much out of a $4.00 admission to anything. Note that your comfort will hinge a great deal on keeping well hydrated, tolerating annoying insects like eye gnats, and repelling chiggers with sulphur or another treatment.

Bentsen Rio Grande Valley State Park

I recently returned from a vacation (being currently unemployed the term “vacation” seems inappropriate, but…) to the southern tip of Texas where I met up with two other amateur entomologists (the quality of their studies makes “amateur” seem inappropriate, too). One of our destinations was the Bentsen Rio Grande Valley State Park in Mission, Texas. I will now indulge you in a rave review of this amazing piece of real estate.

Be advised, our party was there in the first week of June, clearly the “off season” for park visitors. Expect heavy crowds during the “wet season” and fall migrations in September and October.

There is plenty to see in late spring and early summer, however, including lots of birds like this Groove-billed Ani, Crotophaga sulcirostris, one of a pair that was nesting right at the visitor’s center. After imaging the bird, I noticed a sand wasp in the genus Bicyrtes that was digging a burrow at my feet. I hardly knew where to point my camera the whole time I was there.

The visitor’s center is just the tip of the iceberg. The bulk of the park is located across a canal. The road is closed at the canal and Border Patrol habitually stakes a vehicle at this post. A tram, towed behind a pick-up truck, transports park visitors through the park, which is otherwise closed to vehicular traffic. One may then hike on trails that start at the various tram stops.

Wildlife feeding stations are placed at various points, equipped in some cases with “blinds” consisting of walls with holes for your camera or binoculars. While birds were not particularly abundant when I looked, the oriole feeders with orange halves were overwhelmed with emperor butterflies, genus Asterocampa.

Bentsen Rio Grande Valley State Park is named after the Bentsen brothers of political fame who donated the 760 acre parcel to the state, largely in exchange for lands they developed elsewhere. The park, which opened in 1965, is also the headquarters of the World Birding Center.

Expect to see an abundance and diversity of butterflies, dragonflies, and damselflies as well as birds when you visit the park. There are also reptiles, like this Great Plains Rat Snake, Elaphe guttata emoryi that I encountered one night near the visitor center. Western diamondback rattlesnakes, Crotalus atrox, also occur in the park, so do pay attention to where you are walking.

The highlight of my recent visit (and there will be many more if I have my way) was, without a doubt, spying this bobcat sitting on the wall at the entrance to the park after an afternoon thunderstorm had subsided. Do visit yourself and make your own memories at this jewel in the Texas state park system.
