First Blade Delivered to Pantex Renewable Energy Project
The first wind turbine blade is delivered to the site of the Pantex Renewable Energy Project Thursday. Work crews are beginning to erect the first of five wind turbines that will make up the PREP project. When it is completed this spring, PREP will be the largest federally owned wind farm in the country and will provide approximately 60 percent of the average annual electricity need for the Pantex Plant.
Wild Pantex – Spotlight on Wildlife
Article by Jim Ray, Pantex Wildlife Biologist/Scientist
Our pickup made its way slowly down the dusty two track pasture road. We were two miles into a 24-mile spotlight survey that we had begun once it had gotten good and dark. Our crew consisted of a spotlighter for each side of the vehicle, a Security Police Officer to provide key support and, on this night, a co-worker had come along to help us out as a data recorder. And trust me, our night had been well coordinated – assistance by Security, and notification to the Pantex Operations Center, Carson County Sherriff’s Office, Texas Parks and Wildlife Department, and Texas Tech Research Farm.
As we crept along, one million-power spotlights shown out each side of the vehicle. Its holder would watch for eye-shine, or even the outline of the animal itself if close enough to the vehicle. We stop and glass (binoculars) an animal when we need to, but otherwise we record what we have seen at the end of every mile.
We had already observed two deer and a few cottontails when Monty Schoenhals asked me to stop and identify a set of eyes that would occasionally light-up as it made eye contact with us. Through my binoculars I could tell it was a deer, but I needed it to stand-up in order to have a chance of identifying the species. A quick blow on a predator call and it did just that. An eventual glimpse of its light-colored rump and rope-like tail positively identified it as a mule deer and off we went continuing along the survey route.
Spotlight surveys are an important element of our natural resources surveillance program. We spend much time and effort trying to document and monitor our natural resources, and we utilize that information for protecting them, and making land management decisions. I initiated the spotlight surveys back in 2000, my second year at Pantex. Initially, they were aimed at trying to detect swift fox, then, a subject of much debate as to its presence or absence. I had participated in many a deer survey over the years and had also assisted with those for swift fox. Although, not a good technique to estimate numbers of swift fox in an area, you can sure detect their presence if there is a population. Although there is no hint of a swift fox at Pantex, the surveys have been continued due to the opportunity to document and monitor the other nocturnal animals that we come across.
A typical spotlight survey will take us from two to three hours to conduct depending on how many stops that we have to make to glass and identify eyes that are a considerable distance from the vehicle. Animals that we have recorded over the years on these surveys include badgers, black-tailed jackrabbits, bobcats, cottontails, coyotes, gray fox, feral cats, mule deer, raccoons, striped skunks, and white-tailed deer. In some years, it may be the only means of documenting a badger, a gray fox or, less so, a white-tailed deer.
We use the spotlight data every year to supplement other data gathered by a variety of survey methods. For the most part, I just use it for presence/absence-type data and this is included in annual reports and all-time species lists.
Whether in Palo Duro Canyon, the Canadian River bottom, or on the flat plains of Pantex, it sure is a different world out there at night in the lit-up beam of a spotlight. It is another view of our Wild Pantex, one that most will not get to see, and one that we look forward to every year.
Corps of Engineers General Visits Pantex
HEPF sets bar for project management
Lt. Gen. Tom Bostick, commanding general of the U.S. Army Corps of Engineers (USACE), visited Pantex this week to tour the High Explosives Pressing Facility (HEPF). Bostick toured the facility and said he came away impressed, singling out HEPF as an excellent demonstration of what can happen when federal agencies and contractors work together effectively to manage projects. USACE is managing construction in cooperation with NNSA, B&W Pantex and main construction contractor Kiewit Building Group.
Construction on HEPF is approximately 90 percent complete and is on schedule and under budget. When finished, the $65 million project will combine high explosives work from a half dozen older buildings – two dating back to World War II – into one state-of-the-art facility.
Wild Pantex – One Tough Ole Mouse
Article by Jim Ray, Pantex Wildlife Biologist/Scientist
Recently a Pantexan couple were fortunate enough to see and photograph a strange mouse at their new home in my neighborhood north of Canyon. This mouse was “different” in that it had a very short tail. Their visitor was one of the most unique mammals in our area, and I was impressed that my neighbors had already properly identified it as a grasshopper mouse.
Our local grasshopper mouse is the northern grasshopper mouse. It is found in our prairies and I first became acquainted with them while trapping for my Mammalogy collection while a student at Texas Tech. I found them to be an easy catch in the grasslands and playa edges around my hometown of Dalhart. Evidently, they have a fondness for peanut butter, as do most mice.
The northern grasshopper mouse is found in western North America from southwestern Canada into northwestern Mexico. This is a stoutly-built mouse, with a short tail that is less than one-third of its body length. Its color is drab brown to reddish brown, with white underparts. Its short tail stands out, causing the mouse to resemble a hamster.
So, besides its short tail, what makes this animal so unique? First off, this mouse is a predatory species, subsisting off of a diet that includes insects and other invertebrates, as well as mice, reptiles, and even grassland birds. NO FOOLING! Additionally, this animal has a well-known vocalization that resembles a scream or a howl. It is believed that it is given while hunting as well as for territorial reasons. During this process, the mouse stands on its hind legs, throws its head back, and gives it all he/she has.
Here is a recording of a grasshopper mouse vocalizing, which I can attest to, is a common sound at night in the grasslands of Pantex!
Pantex and Texas Tech University actually has some pretty good data on grasshopper mice. During two different research projects that looked at what wildlife species utilize prairie dog colonies versus prairie without prairie dogs, Texas Tech and Pantex discovered that the grasshopper mouse was more abundant, by far, in prairie dog colonies than in prairie not occupied by prairie dogs. In fact, they were the only small mammal species that showed a strong relationship to prairie dog colonies. No doubt, the burrows of prairie dogs and the preponderance of ground-dwelling insects that we also found to be highest on prairie dog colonies, make these areas attractive habitat to this species. BTW, when captured these guys smell horrible, a likely tactic used to get an occasional predator to drop him.
Here is an interesting statistic for you! The number one predator of a well-studied population of Texas horned lizards in South Texas is…you guessed it – the northern grasshopper mouse! This may explain why we find fewer than expected horned lizards in the very promising-looking habitat (for horned lizards) found in prairie dog colonies at Pantex. The question is, is this because of predation by grasshopper mice (and burrowing owls??) or are our Panhandle horned lizards programmed to avoid this predation by avoiding prairie dog colonies?
So, next time you are out on the prairie at night, listen for the howling of grasshopper mice. Perhaps, before, you assumed it was a bird. Now you know that it was one tough ole mouse!

Wild Pantex – Wildlife Research on the Texas Tech Research Farm
Article by Jim Ray, Pantex Wildlife Biologist/Scientist
The Texas Tech Research Farm is comprised of almost 6,000 acres of land lying between the Pantex Plant and U.S. Highway 60. Operated as a production farm and ranch, the land doubles as a safety and security buffer zone for Pantex.
Wildlife species typical of the High Plains of the Panhandle roam and feed in its prairies and croplands, and waterfowl and shorebirds are fond of two playa wetlands when Mother Nature is gracious enough to provide surface water. Like on the 12,000-acre DOE/NNSA portion of Pantex, during one of my trips across Texas Tech, I may encounter a herd of mule deer, a few white-tailed deer, a bald eagle, or even a bobcat wearing a G.P.S. collar around its neck.
Often, I spot a Texas horned lizard dash off the road ahead of me, and as I stop the vehicle it dives into escape cover on the side of the road. In this case, I locate the lizard, which in Texas, bears a state-threatened status designation. I catch it, and now this lizard will be marked and tracked, becoming one of many from the Texas Tech property to be part of a growing body of wildlife research being conducted there.
Formerly, a host for agricultural research relating to animal science, soils, crops, water conservation, entomology, and range management, little research had occurred on the Texas Tech property for the better part of two decades. Beginning in 2003, research on prairie rattlesnakes begin extending onto Texas Tech from the main Pantex property when a few rattlesnakes being radio-tracked by Pantex and Dr. Richard Kazmaier of West Texas A&M University (WTAMU), made excursions across the boundary between the two properties. My, how things have changed since that time!
Texas Tech Research Farm is now host to several Pantex-sponsored research projects, including work on bobcats, Texas horned lizards, and pre- and post-monitoring of birds in advance of wind energy development. In cooperation with Pantex staff, WTAMU’s Dr. Ray Matlack leads the work related to bobcats and wind energy, and besides work on rattlesnakes, Dr. Kazmaier also led the work on horned lizards. Dr. Clint Boal, USGS Texas Cooperative Fish and Wildlife Unit at Texas Tech University, has joined the collaboration on a portion of the work dealing with birds-of-prey nesting in and near the proposed turbine fields. A considerable amount of research has been performed by Texas Tech wildlife faculty and students at Pantex, but this was all on the adjoining USDOE/NNSA property.
Aside from the value of the information being generated by these studies, it is a great sight to see students, professors and Pantex staff conducting fieldwork across the site, which, depending on the occasion, might include the marking of a horned lizard, setting a trap for a bobcat, applying a radio-transmitter to a Swainson’s hawk, or conducting a survey for grassland birds.
As the name implies, the Texas Tech Research Farm and wildlife research are a great fit. Data from that property adds greatly to the information needs valued by Pantex in the realm of wildlife and habitat management.
