At the National Butterfly Center – South Texas, Day 3

IMG_2544.JPGWhen you first arrive at the National Butterfly Center, you see a quiet pool with lotus and other plants, and then walk to the visitor center entrance through patches of flowers alive with bees and butterflies. In our visit on October 18, these plants were heavily visited by queen butterflies (among many others), creating a kaleidoscope of black-edged orange wings with a sprinkling of white spots. But amid the peace and beauty of the center’s gardens looms a threat to the center’s integrity, as well as a threat to our system of fairness and due process. Clint and I were there to learn about the beauty of the place, the work of the center staff, as well as the threat that the property will be torn apart by a border wall. The Center’s director, Marianna Trevino Wright, was very generous, taking us on a walking tour of the 30 acres at the front of the center and then a tour of the 70 additional acres of habitat behind a canal and levee that currently can be driven or walked over.

Knowing our interest in reptiles and amphibians, she first took us down a trail where an indigo snake periodically turns up. While we did not see the indigo, we did find a marine toad (or “cane toad”) hunkered down in a big lump on top of a cut tree stump, several feet off the ground. Wright said that they climb, and here was a clear demonstration of that! Marine toads are found in Central America and the Mexican coasts, making it barely into the United States along several counties of the lower Rio Grande Valley. It is our biggest toad, growing to roughly four to six inches long. Unfortunately, the species has been introduced in several spots around the world and is a harmful invasive in those areas. Marine toads have very large parotoid glands that produce toxic secretions that discourage predators, and while they are not dangerous to humans (provided you don’t eat them!) it is important to wash your hands if you handle a marine toad.

A little later, as the trail bent around to another area with plants for pollinators, a group of chachalacas ran, hopped, and briefly flew nearby. These birds are roughly chicken-sized, mostly a sort of gray-brown color with a buff-colored belly and white-tipped tail feathers, and we saw several groups at the Santa Ana National Wildlife Refuge. There, they usually moved about on the ground and on low branches, and sometimes one would trot along in a way that reminded me a little of a big, chunky roadrunner. Like the roadrunner, their flight was often low and for short distances. Here at the National Butterfly Center, this small group emerged from the brush, hopped onto something and flew on to the next group of trees.

Wright showed us the canal and levee that divides the front and back of the property. The North American Butterfly Association (NABA), which is the parent organization to the Center, owns the land that the levee is on, but the government has an easement at the levee for flood control. The easement would allow government officials or contractors to enter the land and use it for specified purposes. While the language about the purpose of the easement may not say “border wall,” the government can describe the wall as a “fence” and assert that it is an improvement to the levee, thereby attempting to stay within the purposes of the easement.


Part of the property behind the levee

On the other side of the levee, the Center’s property is mostly a combination of forest and the kinds of plants that make up the south Texas thorn scrub. The low mesquites, acacias, and other trees shelter cacti and various shrubs that can support a variety of wildlife. A little over a mile down the road, we emerged at the banks of the Rio Grande, in this spot looking wide and grand, indeed. The possibilities for supporting wildlife and providing education and research opportunities are clear. Wright described how the Center, as one part of the chain of refuges, preserves, and parks, is supposed to function as a conservation corridor, connecting habitat up and down the river to support everything from indigo snakes to ocelots, Texas tortoises to great kiskadees. Along with preserving a piece of the lower Rio Grande habitat, the Center is also busily helping schoolkids and others learn about wildlife. Wright said that they worked with 6,000 kids last year, and they are working with Streamable Learning to provide virtual field trips to classrooms anywhere and everywhere.

Unfortunately, the border wall will significantly limit some possibilities and destroy others. The threat is not off in the distance, it is here right now. Last July, a government-contracted work crew showed up on the back property, with no notice and no communication to the Center, beginning to take earth samples and cutting trees and brush to widen an already wide dirt road. It is worth noting that this was not on the levee itself, where the government has the easement, but along a 1.2 mile road owned by the Center running back to the Rio Grande. Customs and Border Protection (CBP) come onto the property at will, and occasionally things are tense. Wright said that the NABA has filed a notice of intent to sue CBP regarding their destroying habitat and property without due process – the Center got no notification and no opportunity to challenge what was happening in court. Keep in mind that CBP’s plans not only include a wall of concrete and steel bollards on top of the levee, but clearing a 150-foot zone around the wall that will be barren, and setting up lights and surveillance around the wall. Wright told us that she has been told that the workers will be back, accompanied by armed CBP agents. It appears that the intent to go to court means nothing, and they may show up and clear the land, getting it done before NABA would even be able to try to get a court injunction that would make them wait until the legal question is settled.

For some background information about the wall in the lower Rio Grande Valley, you could read “Over the Wall,” an article from this past June in the Texas Observer. Another article described how the wall would destroy the Santa Ana National Wildlife Refuge, in the words of a federal official quoted by the Observer.

We know that readers of this blog may be united in an interest in wildlife and habitat but have diverse political opinions. However, my perspective is that this is not necessarily a political issue in the usual sense. I don’t care who you vote for, but chances are you support conservation of wildlife and habitat, nature education, and the preservation of our rights as private citizens (or private nonprofit organizations) to hold private property without worry that the government will simply take it, overrun it, or destroy it without due process – without our having our day in court to say why it shouldn’t happen.

It you would like to support the National Butterfly Center, there are a couple of ways to do this, through their website. One is to support their legal defense fund, and the other is to download and send their model letter to the U.S. Army Corps of Engineers supporting NABA’s right to due process prior to CBP taking part of their land, making a strip of it completely unusable for its purposes, and consigning over half of their property to a “no man’s land” behind the wall.
