America’s hunters and wildlife managers are well into the feral hog war. More than 6 million wild pigs roam the country, gobbling down native flora and outcompeting native fauna. They’re also hell on agricultural crops. According to the U.S. Department of Agriculture, hogs cause $1.5 billion of damage annually.
“Researchers think that number may be closer to $2.5 billion now, but more research needs to be done to determine an accurate figure,” says Ben Westfall, the National Deer Association’s conservation coordinator.
There are massive efforts by government agencies and private landowners to cull feral hogs and stop their spread. Whitetail deer managers are at the tip of the spear, because pigs can also have a negative impact on deer.
Unfortunately, there hasn’t been a lot of formal, university-led research on how pigs impact whitetails.
There doesn’t need to be university-led research. Those are the same pointy head idiots who recommend against hunting to cull the hog population (but recommend government sponsored “sharp shooters”).
I can tell you what happens. They compete for the same sorts of food and bedding areas. If the feral hogs come in, the deer leave. It’s that simple. The deer won’t fight the hogs. But I think the article does get to that.
When hogs first appear on the scene, whitetails tend to avoid them, meaning they settle for lower quality bedding areas and food sources. This is even truer for mature bucks, which seem to have less tolerance for hogs than younger bucks, does, and fawns do.
However, in areas where hogs have been present for years, deer seem to get used to them.
Well, that last part is only sort of true. They are still displaced and still compete for the same food and bedding, they do learn to live in the same geographical area, but if you want to deer hunt in an area heavily populated by hogs, you’re best bet is to move on.
“Based on my observations, deer do adapt to hogs if they’ve been present a long time,” says, Dr. Grant Woods, a renowned deer biologist and founder of Growing Deer TV. “I see deer in South Florida ignoring hogs unless they get within 30 yards or so. I’m sure where hogs are new neighbors, deer give hogs more space. There’s certainly more food for deer if hogs are removed, and I suspect they’d be a bit calmer.”
Still, whitetails can be forced to move out of areas if hogs over-browse habitat and dominate resources. The higher the hog densities, the worse this problem gets.
That’s what I just said.
“It’s more about the food sources in the area,” he says. “If the hogs eat all the food, the deer will move to a new food source and return once the food source is available.”
The good news is that when hogs are removed (or severely culled) from the landscape, deer seem to bounce back. Anecdotes from the field are somewhat mixed but they are mostly promising. According to most deer managers I spoke with, whitetails generally return soon after hogs are removed. This can take longer in areas where the habitat is seriously degraded, but under average conditions, whitetails often return rather quickly. This is especially true in areas that offer adequate bedding areas, along with food, water, and security cover.
Once feral pigs become established, landowners can remove most of the hogs from their property. However, management is often very costly, and if neighboring landowners aren’t applying equal or greater management efforts, hog populations will continue to grow.
That’s why feral hogs can’t be eradicated. Culling the population on a 100 acre plot of land (whether by hunting or trapping, or both) does no good if the neighboring farms don’t do exactly the same thing, and as I’ve pointed out before, that’s very, very, very expensive.
Feral pig managers have a mighty steep hill to climb. Typical hunting tactics have proven to be mostly useless as management tools. Sure, hog hunting is fun. And it might remove a porker or two from the property. But on a landscape population level, it doesn’t accomplish much, and it can make pigs even warier. Even when running dogs, hunting doesn’t remove enough hogs to decrease overall population densities.
Furthermore, fertility control isn’t in heavy use yet. The heavily debated toxicant called Warfarin isn’t permitted in any state, and there’s a chance it won’t ever be.
Good Lord. There’s that awful, horrible idea floated again of putting a toxicant into the environment. For heaven’s sake, don’t do that. We have enough toxicants in the environment already. Besides, the unintended consequences of such a introduction could be terrible.
Generally speaking, it’s easier to trap pigs when food is scarce in the winter and early spring. This is when bait is most effective. It’s also best to trap when the most sows are pregnant. (This is easier than trying to trap sows and their piglets together.) Capturing the entire sounder is the goal—from the biggest sows down to the smallest members of the group. Of course, hogs like to stay closer to water, so bottomlands, marshes, swamps, and other lowland areas are all good locations to try.
As I’ve said, sounders don’t stick together in proximity the way this tactic makes is seem.
“The best thing the average land manager can do is cooperate with their state wildlife agency and familiarize themselves with the management efforts taking place as well as various programs that may be available to them,” Westfall said. “Many states have hog specific or cost-share programs in which they will work with landowners to help control the problem. It is our responsibility as landowners, managers, and hunters to know what our state wildlife agency is doing, understand that their efforts and methods are based on scientific research, and do our best to assist with their efforts in any way that we can.”
The best thing land managers can do is kill as many hogs as possible as quickly as possible, whenever and wherever they can. This means trapping, hunting, night vision, game cameras, research, communication, and all the things they already know about. I would find it hard to believe that land managers in South Carolina, Georgia, Alabama, Florida, Mississippi, Louisiana, Texas, Arkansas, and other states, don’t already know all about the problems. I’m sure they’ve been engaged in this war for years now. If they haven’t, they need other land managers.
