Why Natural History Collections and Surveys Matter Today

Published

Senior Research Associate 1

A little more than 100 years ago, G.W. Stevens traveled across Oklahoma collecting plant specimens as the director of the Oklahoma State Botanical Survey. A portion of his first collecting trip brought him through Love and Carter counties, where several of the ranches operated by Noble Research Institute are located, ranches where I’ve spent much of the last nine years involved in various research projects.

Stevens’ field survey was the first major undertaking to identify what plants occurred in Oklahoma. Up until that point and for the next 50 years or so, the study of natural history mostly revolved around two questions: what and where. In other words, finding out what species were present and where they occurred. The only way to answer those questions was to go out and collect specimens which then were dried, mounted and deposited in herbariums, usually at universities. While people could come along and make maps or study the anatomy of all the specimens of a particular species, nothing really exciting happened in those collections.

As new technologies were developed and improved in the 1980s and ’90s, the attention shifted to looking at how species and groups were related to one another based on DNA and pollen analysis. This was pretty attractive to folks because it all took place under air conditioning and didn’t involve chiggers and ticks. Tissue samples for a study could easily be extracted from preserved herbarium specimens. Natural history studies dropped off dramatically and are continuing to decline.

There are a lot of questions out there today that didn’t exist when G.W. Stevens and other early collectors were stumbling around through the prairies and woods of Oklahoma. Natural history collections and surveys can contribute a great deal to the answers.

VEGETATION REFLECTS ECOSYSTEM HEALTH

From historical collections and newer samples collected in particular habitats, we can begin to develop a concept of ecosystem health. How many native species are present versus non-natives? How closely do the species present today represent those documented for the site in the past? How have environmental changes affected native vegetation? How have land use practices influenced native vegetation? What can be inferred from the current vegetation about historical land use?

If we detect a difference — some species are absent that were present and new species have appeared — we can ask: What about this site has changed? How rapidly are changes taking place? Can we implement management practices to reverse the changes? Rarely do species invade an intact community. There is usually some disturbance that has taken place that sets the stage. Often the culprit is overgrazing, but it also may be something like a lack of fire. For example, eastern redcedar takes advantage of both situations and causes havoc by invading grassland plant communities.

A great deal of information about the status of vertebrate and invertebrate species can be inferred by the status of the plant communities present. In most cases, the plant community is the habitat for those species. If it’s gone, they’re gone.

During field work in the heavily forested Big Thicket in southeast Texas, I occasionally came across single pitcher plants under closed-canopy pine forests. If they’re only supposed to grow in pine savannas, why were they growing in the middle of the forest? Fires had been suppressed for so long that the pines had taken over the original savannas, which were the habitat for the pitcher plants. I was finding relict populations. Collections data can let us know where such habitats once occurred and where they might occur again, if properly managed.

Collecting Provides Insight Into Invasive and Endangered Species When dealing with invasive species, other questions arise. Have those species always been around, or are they introduced? When did they first turn up? If they have always been around, why are they causing problems now? What has changed? How fast is the change occurring? Collections data can help answer those questions as well.

Natural history collections may also provide insight into endangered species that are particular about where they live. Data on specimen labels about geology and soils can be put into a GIS system and analyzed to locate other potential sites where those species might be found or could be reintroduced. It is also possible that what we thought was an endangered species based on museum collections isn’t nearly as endangered once someone starts to focus on collecting them. Many organisms are easy to overlook and just are seldom collected.

COLLECTING HELPS ANSWER BIODIVERSITY QUESTIONS

How many species occur on a site? Do some appear only during or after really dry periods, or really wet ones? Several native forbs dramatically increase in abundance after fires. It’s not that they are suddenly invading, but it’s how that plant community is responding to fire. After every fire, those species behave in that fashion. Two years after the fire, the forbs will once more be minor components of that community. Some of the species occurring on a site don’t show up every year, or even every decade. Seeds remain viable in the soil for extended periods of time and may germinate only when conditions are just right. This may occur only when the overhead canopy has been removed, such as in the case of a fire or after a severe drought.

Collecting in an area, even over an entire season, still doesn’t capture all of the biodiversity that is likely to be present there. I’m specifically referring to plants here, but I think that trend holds true for whatever group of organisms one might study. Collecting is the only way to answer many biodiversity questions. We use some other technologies such as camera surveys or acoustic surveys to help measure biodiversity with animals, but they don’t work with plants.

Working the Night Shift

Published

on

By Ann Asher

Bats have never had the best public relations team.

They come out at dusk, fly in quick, uneven patterns and have spent too many years tied to scary movies, old barns and Halloween decorations. For a lot of people, the first reaction to seeing a bat is ducking, squealing or hurrying back inside.

Out in the real world, especially across Texas, bats do quiet work most of us never see.

While we are closing gates, turning off barn lights, watering the last few plants or heading toward the house for the evening, bats are just getting started. Many of the bats found in Texas feed on insects, including moths, beetles and other night-flying insects. That makes them part of the natural system working across farms, ranches, ponds, creeks, barns and backyards after dark.

For farmers and ranchers, that matters. Insects do more than annoy you in the backyard. They can affect crops, gardens, livestock comfort and the general balance of the outdoors. Bats won’t wipe out every mosquito or pest insect on a place, but they are beneficial wildlife. They feed at night, after many birds and other daytime predators have quit for the day, which gives them their own role in the landscape.

Contrary to a common misconception, bats are not blind. Many bats use echolocation to find insects and move through the night, but they can also see. Another old fear is that bats want to fly into people’s hair. They do not. A bat flying low or close is usually chasing insects or trying to steer away, not looking for trouble.

Bats are still wild animals, though. Respect them, and don’t handle them.

Rabies is the main safety concern people think of with bats, and it is a serious one. Not every bat has rabies, but treat any bat found on the ground, acting strangely, unable to fly or inside a home with caution.

Never pick up a bat with bare hands. If a person or pet may have been bitten or scratched, or if there is any chance of contact while someone was sleeping, contact local health officials or animal control for guidance.

Common sense goes a long way. Keep pets vaccinated. Teach children not to touch wildlife. If a bat gets into a house, don’t panic, but don’t ignore it either. Close off the area if possible, keep people and pets away and contact the appropriate local professionals if there is any concern about exposure.

Around farms and ranches, bats may roost in trees, bridges, barns, old buildings or other sheltered places. Sometimes that is not a problem. Other times, especially if bats are getting into living spaces or busy work areas, you may need to exclude them.

Timing matters. In some cases, sealing an opening at the wrong time can trap young bats inside or create a bigger problem. Wildlife professionals or Extension resources can help property owners find the safest and most responsible way to handle a bat colony in a building.

Some people put up bat houses, which can be a good option when placed correctly. A bat house doesn’t guarantee that bats will move in, however. Location, height, sun exposure, temperature and nearby habitat all matter. Natural roosting areas are important, too, which is why dead trees, wooded edges, water sources and undisturbed spaces can help support bat populations.

Landowners don’t have to turn their place into a bat sanctuary. It can be enough to understand that bats have a job to do. They share the same outdoor world as songbirds, pollinators, frogs, owls, deer and the insects we notice whether we want to or not.

Bats are also a good reminder that something useful isn’t always pretty, popular or easy to appreciate at first glance.

Some of the hardest-working creatures on a farm or ranch are the ones we barely see. Bats don’t ask for attention or show themselves in daylight. They take the night shift.

The next time you see one dipping and turning through the evening sky, try not to think of it as spooky. Think of it as a neighbor clocking in after dark, doing its work while the rest of us head inside.

Built to Run: The Greater Roadrunner in Oklahoma

Published

on

There are some birds you hear long before you see them. Others announce themselves with bright colors or a pretty song. Then there is the roadrunner, a bird most of us recognize from a quick glimpse across a county road, a flash of tail along a fence line or the unmistakable sight of a long-legged bird moving with purpose through the pasture.

The roadrunner also happens to be my mother’s favorite animal. No matter how many times she sees one, it never seems to get old. If one darts across the road or shows up along a fence line, she gets excited every time, as if it is some rare treat. I have come to understand why. There is something about a roadrunner that makes a person stop and pay attention. It is a little odd, a little comical and a whole lot tougher than its cartoon reputation ever gave it credit for.

The real bird is not just a desert runner with a famous call. It is a native predator, a skilled survivor and one of the more interesting birds found in Oklahoma.

The greater roadrunner, Geococcyx californianus, is a member of the cuckoo family, though it does not fit the delicate image many people may have of a cuckoo. This is a ground-dwelling bird built more for running than flying. It can fly when it needs to, but most of the time it would rather use its legs. Roadrunners have been reported running around 15 to 20 miles per hour, which is plenty fast enough to surprise a person when one darts across a road or disappears into brush.

In Oklahoma, roadrunners are most often associated with open country, grasslands, shrublands, fence rows, cedar breaks and pastures with enough cover to hunt and hide. They are more common in some parts of the state than others, but they are not limited to the desert image many people picture. A quiet gravel road, a brushy pasture edge or a sunny spot near a cedar thicket can all be good places to catch a glimpse of one.

At first glance, the roadrunner may look mostly brown and gray, but it is worth a closer look. Its mottled feathers help it blend into dry grass, brush and bare ground. The long tail is often held up or used like a rudder when the bird is running. The shaggy crest on its head gives it an alert, almost mischievous look. In the right light, its feathers can show more color and detail than a quick roadside sighting suggests.

One of the most distinctive things about a roadrunner is its feet. Like other members of the cuckoo family, roadrunners have zygodactyl feet, which means two toes point forward and two point backward. The track can look like an “X,” making it harder to tell which direction the bird was traveling. That unusual footprint has been part of Southwestern folklore for centuries, and it is easy to see why. Even its tracks seem to fit the bird’s mysterious, always-on-the-move personality.

While the cartoon version of the roadrunner made a living outsmarting coyotes, the real bird makes a living by hunting almost anything it can catch. Roadrunners are omnivores, but their diet is heavily made up of animal matter. They eat insects, grasshoppers, scorpions, centipedes, lizards, small snakes, small mammals, frogs, toads, eggs, young birds and carrion. They will also eat fruit and seeds, especially when animal prey is less available.

Their reputation for killing rattlesnakes is not just folklore. Roadrunners are known to take on venomous snakes, using speed, timing and repeated strikes to the head. They may also beat larger prey against the ground or a rock before swallowing it. As harsh as that sounds, it is part of what makes the roadrunner such an effective predator. This bird is not picky, and it is not easily intimidated.

That hunting ability can make roadrunners useful neighbors on farms, ranches and rural homesteads. They help control insects, rodents and reptiles, and they fill an important role in the food chain. Of course, they are not only predators. Roadrunners can also become prey for hawks, owls, raccoons, coyotes and other animals. The cartoon may have allowed the roadrunner to win every time, but in the real world, survival is never guaranteed.

Roadrunners have several adaptations that help them live in hot, dry country. Much of the water they need comes from the moisture in their prey. They also have ways to conserve energy and handle cool desert nights and chilly mornings. On cold nights, a roadrunner can lower its body temperature and become less active. In the morning, it may turn its back toward the sun and raise its feathers to expose a dark patch of skin that helps absorb heat. Anyone who has watched livestock, wildlife or even a barn cat find the first warm patch of sunshine can appreciate that strategy.

Their nesting habits are also interesting. Roadrunners often form long-term pairs, and both the male and female help with nesting and raising the young. Nests are usually built low in a tree, shrub, cactus or dense vegetation, often with sticks, twigs, grasses and other materials. The female typically lays several eggs, and both parents take part in incubation and feeding the chicks after they hatch.

Young roadrunners are not born ready to chase lizards across the pasture. Like many birds, they hatch helpless and depend on their parents for food and protection. After they leave the nest, they may continue to rely on the adults while learning to hunt. In a good year with plenty of food, roadrunners may raise more than one brood.

For all their toughness, roadrunners still depend on healthy habitat. Brushy cover, native grasses, insects, reptiles and small mammals all help support them. A perfectly manicured landscape does not offer much to a bird that hunts on the ground and needs places to hide, nest and ambush prey. On rural properties, leaving some natural cover, protecting native plant diversity and avoiding unnecessary pesticide use can benefit roadrunners and many other wildlife species.

Roadrunners are also a good reminder that Oklahoma wildlife does not have to be rare or dramatic to be remarkable. Some of the most interesting animals in the state are the ones we pass every day without thinking much about them. The bird that sprints across the road in front of the pickup is more than a familiar blur. It is a snake-hunting, sun-bathing, X-footed member of the cuckoo family that has figured out how to make a living in some unforgiving country.

Maybe that is why my mother loves them so much. A roadrunner sighting still feels like a small surprise, even in country where they belong. The greater roadrunner may not actually say “meep meep,” and it may not always outrun a coyote, but it has earned its reputation all the same. In Oklahoma, this long-tailed bird is part predator, part survivor and part roadside surprise, and that makes it worth watching for.

Late Summer Fishing

Published

on

By OKFR Staff

Right now, fishing in Oklahoma can feel a little like everything else this time of year.

It is hot, and the water is warm. The easy part of summer has worn off, and if you stand on the bank in the middle of the afternoon expecting fish to jump on the hook because you showed up, you may be disappointed.

The fish are doing what most of us do by late summer: looking for cooler places, easier meals and the most comfortable part of the day.

Across Oklahoma, late-summer fishing often comes down to timing. Early mornings, evenings, overnight hours and cloudy days can make a big difference. Fish may still feed during the heat of the day, but many species are more active when light is lower and water temperatures are less punishing.

The Oklahoma Department of Wildlife Conservation (ODWC) notes that summer fishing often improves during low-light periods, especially for species like catfish, which are active at night and bite on punch bait, stink bait, cut bait and other scented baits.

Catfish are one of the best late-summer targets for Oklahoma anglers. Channel catfish and blue catfish both bite this time of year, and they are a good choice for families, bank anglers and anyone who wants to keep the setup simple.

Look around creek channels, points, riprap, deeper holes and areas where wind or current may be moving food. Cut shad, worms, prepared stink bait, punch bait and other strong-smelling baits can all work. If you are fishing a pond, try near the dam, in deeper water or around structure, especially later in the evening.

For largemouth bass, August can be tough but still productive. The biggest adjustment is realizing that bass may not be where they were in spring. In hot weather, they often hold near shade, deeper water, vegetation, docks, brush, creek channels and other spots that offer cover or access to cooler water. Early in the morning, topwater baits are worth trying along the bank, around grass or near shallow cover. As the sun climbs, it often pays to slow down or go deeper with soft plastics, jigs, crankbaits or other baits that can reach fish holding off the bank.

White bass can also provide good late-summer action, especially when they are chasing schools of shad. This kind of fishing can go from quiet to exciting in a hurry.

Watch for baitfish breaking the surface, birds working over the water or sudden splashes that make the lake look like it is boiling. Spoons, slabs, small swimbaits, inline spinners and shad-colored lures are all good choices.

ODWC’s white bass guidance notes that anglers can succeed in summer by vertically jigging spoons and slabs off the bottom over ledges, a technique that works well when the fish are not visibly schooling on top.

Crappie can be more challenging in late summer, but they do not disappear. They may move deeper or hold tighter to brush, standing timber, docks, bridge pilings or other structure. Instead of beating the bank like you might in spring, look for shaded or deeper cover. Minnows and small jigs are still reliable choices, but presentation matters. Often the key is getting the bait down to the right depth and keeping it there long enough for a fish to decide it is worth the effort.

Don’t overlook bluegill and other sunfish, especially if you are taking kids fishing or want steady action. Look for them around docks, weeds, brush, rocks and shaded banks.

A small hook, light line, a bobber and a worm remain one of the most dependable combinations in the tackle box. In ponds, bluegill fishing can keep everyone interested while you wait for catfish or bass to cooperate.

No matter what you are fishing for, late summer rewards anglers who pay attention. Look for shade, baitfish, moving water, wind-blown banks, deeper edges, brush piles and places where fish do not have to work hard for a meal. In clear water, natural colors may work better. In stained water or low light, a little more scent, vibration or contrast can help fish find the bait.

August rewards smarter fishing more than harder fishing. Go earlier, stay later, and try after dark where it is safe and legal.

Bring plenty of drinking water, watch the weather and remember that heat is hard on both anglers and fish. If you are catching and releasing, handle fish quickly and get them back in the water as soon as possible.

Before heading out, check the current Oklahoma fishing regulations, including license requirements, daily limits and any lake-specific rules. The 2025-26 Oklahoma Fishing and Hunting regulations are available through ODWC, and rules can vary by species and location.

Late-summer fishing may take more patience, but plenty is still biting for anglers willing to adjust. The fish are still out there. Like the rest of us, they are trying to beat the heat.
