Invasive species… and more invasive species

A recent study revealed that globally, about one-fourth of all invasive species are “new” invaders, meaning that they have not previously been invasive in other areas. In other words, although we can predict that certain species will become invasive in new environments, there are other species that may invade even though they haven’t caused problems elsewhere. An example of an animal that we know is invasive is the wild pig (Sus scrofa). Just about anywhere wild pigs are introduced, they become a major invasive problem. On the other… Read More →

New publication: Texas Water Law

If you’ve never visited the Texas Agriculture Law Blog, now is a great time to check it out! In a recent post, Extension Agricultural Law Specialist Tiffany Dowell Lashmet released a new publication called “Basics of Texas Water Law.” Given this year’s water theme on TexNat, this is a timely publication! Both groundwater and surface water are addressed in this concise, easy-to-read paper. These concepts are applicable not just for agriculture producers, but also for those who use ground and surface water for wildlife.

How much water?

Edited by Dr. Bob Dittmar, Wildlife Veterinarian, Texas Parks and Wildlife Department The water needs of different wildlife species vary widely. Even within a species, an animal’s water needs may differ depending on climate, body size of the animal, reproductive status, and other factors. This is why the daily water intake of a particular species is usually given as a range of values. Below are some of the factors that can influence the specific water needs of a given animal. Physiology Different animals are adapted to different climates… Read More →

The annual TCTWS conference… Read More →

Quail on ice

Earlier this week, a post on the Rolling Plains Quail Research Ranch Facebook page featured a covey of bobwhites huddled up against the cold weather. This leads us to an excellent NatNotes topic: what do wildlife do when it’s cold? Across the rangelands of Texas, some critters are more familiar with cold than others. Most of the bobwhites in south Texas probably haven’t seen this much cold weather in a couple generations, while quail on the High Plains of the Panhandle experience freezing temperatures more regularly. So for… Read More →

All About Water

We’ve experienced some highs and lows and crazy weather in Texas the past few months. But, unfortunately for our rangelands, what we’ve been missing is rain! On Texas rangelands, drought is not an “if” but a “when” and “how long will it last.” So, while we always hope for rain in the forecast, it’s good to prepare for the driest scenario. This year, water will be a regular feature of TexNat posts. We’ll discuss how wildlife use water, how rain affects plant health and diversity, and how all… Read More →

Hunting as population management

Many hunters dream of harvesting a trophy buck. While people hunt for a variety of reasons, including food, tradition, spending time with family, connecting with nature, and seeking that trophy buck, the role of hunting in deer population management is sometimes overlooked. In particular, some hunters do not realize the importance of harvesting does to maintain balanced sex ratios. “Sex ratio” refers to a comparison of the number of males in a population to the number of females. As with most mammals, the sex ratio of white-tailed deer… Read More →

Hurricanes, floods, and wildlife

As Texans continue to recover from the impacts of Hurricane Harvey, and with hurricane season far from over, many people have questions about how these events affect wildlife. Quail are particularly prone to the effects of rainfall. Find out more in this short video by Texas Wildlife Association: Quail vs. Hurricane

Wildlife and flooding

When a natural disaster strikes, wildlife have limited ways to respond. Floods commonly displace many species from their usual homes and allow other species to access new areas. As the water recedes, people may be surprised to find wildlife in unusual places. Most wildlife displaced by flooding is simply trying to find food and shelter. However, if people are unaware of their surroundings, negative encounters with displaced wildlife can result. One particular concern during post-disaster cleanup is snakes. Debris piles created during a storm attract snakes for several… Read More →

Notes about Nighthawks

What’s in a name? Although most wildlife names are pretty straightforward (white-tailed deer have white tails, northern bobwhites say their name), others can be misleading. This post is about nighthawks, which are fascinating birds that are not at all related to hawks! Unlike hawks, which are classified together with other large, diurnal birds of prey, nighthawks are part of a group of birds that eat insects and are most active at night. Other birds in the same family as nighthawks have equally fascinating names, including nightjar, chuck-will’s-widow, whip-poor-will,… Read More →
