The Wildfire continues to grow in the eastern part of the state with latest reports holding at 40% containment. This area is important habitat for many species including the Red Wolf. Fire is an important tool of nature to reshape and regenerate areas and for the most part wildlife quickly adapts and escapes the fire.
Dr James Gallagher of Texas Agrilife Extension Services is currently studying the effects of wildfires on wildlife in Texas;
“While some dead animals are found in the aftermath of a fire, many more are seen wandering the landscape in search of food and shelter,” Gallagher said. “And with smaller-scale fires, mobile species populations like those of birds and white-tailed deer don’t normally suffer too greatly due to their ability to move quickly to escape fires and travel to new locations to find food and water.”
Even under harsh burning conditions, less mobile species like small mammals, Texas horned lizards and snakes, fare reasonably well during a fire itself, he added. But while some wildlife is killed during wildfires, more serious losses can come days and even weeks later.
“Even though the majority of animals may escape a fire, many will suddenly find themselves in the middle of thousands of acres of burned-over country side, with a lot less shelter and food than before,” he said. “Those living near the edges of the burned areas can usually travel to find what they need, as can those living in or near unburned patches. But unburned areas tend to be few and far between. Competition for resources in the unburned pockets can be intense, and those resources won’t last very long.”

US Fish & Wildlife are reporting that within the current foot print of the fire there is no known Red Wolves dens. Most of the Red Wolves have telemetry collars and biologists in the early spring map out where the dens are.
April and May are very exciting months for red wolves - both in the wild and in captivity. It’s pup season! This annual occurrence finds Red Wolf Recovery Program, USFWS, wildlife biologists spending many hours in the field, seven days a week, looking for hidden dens over the five counties of Dare, Tyrrell, Hyde, Washington and Beaufort. Radio telemetry collars tell the biologists that there are 18-20 packs in this 1.7 million acres of northeastern North Carolina - the only place in the world where red wolves roam free in a portion of their original home range. So far for the 2008 pup season, the biologists have found 12 litters with 51red wolf puppies. But there could still be more! For the next several weeks, the 5 red wolf wildlife biologists will keep looking. Ideally, the red wolf field crew would like to find 3 or 4 more dens, but this season has already proven to be a “healthy” denning season. During 2007, 2006, and 2005, 31, 44, and 55 pups (respectively) were found among the wild population. The pups shown above are wild pups from a 2008 litter in eastern North Carolina.

For the most part the pups are big enough now that if a den was threatened I’m sure the adults would get the pups to move out of the path. Of course the unknown question in this event given the overall size as well as the rather long duration of the fire burning in the peat will species crowd up into areas outside of the fire and are those areas big enough to provide food and shelter for the additional displaced wildlife. Dr. Gallagher identified that as an issue in Texas and I’m sure it will be an even bigger issue here given the amount of time this fire could burn.
“The majority of wildlife exposed to wildfire will see a drastic reduction in their amount of cover and a drastic increase in their exposure to starvation and predation,” he said. “Many animals forced to move to more suitable areas will often have to do so at unusual times and in unusual locations. As a result, many of them find themselves coming in contact with humans and, more specifically, their vehicles.”
According to Gallagher, wildlife’s need for shelter is often under-appreciated. Not only does shelter provide a place to avoid predators, it is also essential to help wildlife conserve energy and water. “Without adequate shelter, wildlife is exposed to the elements, requiring them to use up more energy to stay cool or warm,” he said.
Gallagher said it may take several months before an area has adequately recovered to once again support wildlife, and unless growing conditions are adequate, most burned areas will provide marginal wildlife habitat at best.
Although he does not directly mention it I’m sure the potential for diseases is also significantly higher. We’ll have to wait and see what if any long term effects the fire has on the Red Wolf project but right now the impact seems to be minuscule.
