The Cost of Banning Lead for Iowa's Dove Hunt

By Tim Lesmeister

The state of Iowa has come to its senses and opened a dove season, which will start on September 1 and run through November 9. Well, they almost came to their senses. As part of the dove season, hunters will be restricted to lead-free ammunition. Will the onslaught on hunters and shooters ever end? The anti-hunters are always looking for ways to restrict our sport. It's a never-ending battle, it seems, and while they have stepped back a little on trying to ban certain types of firearms, now these zealots are going after our ammunition.

Why would banning lead ammunition restrict hunters? Because the alternatives to lead are much more expensive and this would hinder those with a limited budget. You go through plenty of shells when hunting doves and it will get pretty expensive if you cannot use lead.

So how bad is lead to the environment? The radical environmentalist would have you think that lead is more toxic than nuclear waste. Hunters just want real data to decide, and not much of that exists.

Following is some information gleaned from the National Shooting Sports Foundation (NSSF) web site. While the crazed tree huggers would shout this is a biased site, it was the only place that stated a reasonable argument. Other sites that were against lead ammunition (that showed up on my web search) based their arguments on marginal data or were sentimental, creating an argument based on feelings and faith in their environmental message.

According to the NSSF web site:
Wildlife management policy is based on managing population impacts, not on preventing isolated instances of harm to specific individual animals in a species. Absent sound scientific evidence demonstrating a population impact caused by the use of traditional ammunition, there is no justification for restricting or banning its use.

With very limited exceptions, such as waterfowl and possibly the California condor (upon which the evidence of a causal connection to spent ammunition fragments is far from conclusive), there is simply no sound scientific evidence that the use of traditional ammunition is causing harm to wildlife populations. In the case of raptors, there is a total lack of any scientific evidence of a population impact. In fact, just the opposite is true. Hunters have long used traditional ammunition, yet raptor populations have significantly increased all across North America - a trend that shows no sign of letting up. If the use of traditional ammunition was the threat to raptor populations some make it out to be, these populations would not be soaring as they are.

And is lead ammunition a threat to humans? To put this issue in perspective, consider this statement from the Iowa Department of Public Health (IDPH), a state agency that has tested the blood lead level of Iowa residents for more than 15 years: "IDPH maintains that if lead in venison were a serious health risk, it would likely have surfaced within extensive blood lead testing since 1992 with 500,000 youth under 6 and 25,000 adults having been screened."

Iowa has never had a case of a hunter having elevated lead levels caused by consuming harvested game.

There is simply no scientific evidence that the use of traditional ammunition is having an adverse impact on wildlife populations that would require restricting or banning its use beyond current limitations, such as the scientifically-based restriction on waterfowl hunting. And, there is absolutely no evidence that consuming game harvested using traditional ammunition poses a human health risk. In fact, there has never been a single instance of an elevated lead level in a human in the history of the United States due to consuming harvested game.

The excise tax dollars (11 percent) manufacturers pay on the sale of the ammunition some demonize is the very source of wildlife conservation funding, the financial backbone of the North American Model of wildlife conservation. The bald eagle's recovery, a truly great conservation success story, was made possible and funded by hunters using traditional ammunition. Needlessly restricting or banning traditional ammunition absent sound science will hurt wildlife conservation efforts as fewer hunters take to the field.

Blake, I agree completely, especially on the issue of miss information. This is a Letter to the Editor that I sent in early 2010 regarding an article about eagles getting sick from lead poisoning from lead deer slugs and wounded and unrecovered deer. Send your piece off and be proud that you at least try to set the record straight.

Dear Editor:

This letter is in response to an article published in the Ottumwa Courier on February 10, 2010 entitled Eagles Getting Sick. This article is very similar to one that was published in The Messenger of Fort Dodge by staff writer Dawn Thompson on April 7, 2007. Both articles quote some misinformation and show inconsistencies. In both articles Kay Neumann, executive director of SOAR, blames deer hunters for most, if not all, of this problem that she says is the result of eagles feeding on dead deer that were wounded with lead slugs and then wandered off to die. The biggest problem with this statement is that there is no hard evidence that this is true.

The SOAR web site shows data collected in a study from February of 2004 through December of 2006. This data was collected by the McBride Raptor Project, SOAR, and The Wildlife Care Clinic. The study included 32 eagles that were brought into the center for treatment. Of these 32, 3 had been shot, only 1 showed ingested lead particles, 19 tested negative for ingested lead, and 10 were not tested, including one eagle that was shot. While the data did show that 10 of the eagles did die and 2 others were euthanized for other problems, it did not say that the lead levels were the cause of death, even though blood and liver tests did show lethal or near lethal lead levels. It also did not show that ingested lead particles from lead deer slugs were the cause of these high levels of lead.

Another study done by The Raptor Center at the University of Minnesota contradicted Ms. Neumann’s statement that this problem is becoming more wide spread. This study took place from 1996 to 2008 and was to study lead poisoning as a cause of morbidity and mortality in Bald Eagles. In this study they compared this 12 year period to the preceding 16 years in a study by Kramer and Redig published in 1997. The conclusion was that there was a continuing trend of the incident of lead poisoning but that there was no significant difference between the number of cases admitted per year between the current 12 year study and the previous 16 year study. “Similarly the mean blood lead concentration remained unchanged with a low level chronic exposure predominating”.

Lead isotope analysis showed that the lead was with in the isotope ratio for ammunition supplies but also pointed out something else. Kidney samples showed copper concentrations significantly higher in the lead exposed eagles. This would indicate copper fragment from copper jacketed rifle bullets were being ingested with the lead, and that more of the effected eagles came from areas of the State that allowed high powered rifles as opposed to just shotguns. Ms Neumann’s suggestion of switching to solid copper slugs might bring forth another whole gambit of problems. Copper poisoning has been linked to liver, kidney, and brain disorders along with Wilson’s disease and reproductive problems. So would we be just swapping one problem for another? Surprisingly the treatment for both copper and lead poisoning is the same, chelation.

The last thing I will touch on is Ms Neumann’s comment that hunters are harvesting more deer and most are shot with lead slugs. All of this statement is inaccurate. The Iowa deer harvest has drastically declined for several years. Dropping from a high of over 211,000 deer in 2005 to just 136,000 in 2009, a decrease of nearly 40% in only 4 years. Now if we have another look at the wounded and unrecovered deer being the source of the lead poisoning problem, we can apply some actual numbers to the issue. Iowa DNR data for 2008 shows that during the shotgun seasons, about the only time lead shotgun slugs are used, there were a total of 63,330 deer killed. While I have heard estimates of as high as 10% wounded and not recovered factor, the DNR generally supports less than 5%. That would mean that there were 3,166 wounded but unrecovered deer for the shotgun seasons in 2008. If we estimate that about 30% of those wounded deer actually survive, that leaves us with 2,216 dead deer in the field. Because, as Ms Neumann points out, many hunters have already switched from lead slugs to some of the “non-toxic” copper slugs we should reduce that by another 30%, leaving us with 1,551 possible contaminated deer. Now if we assume that even 75 percent of those actually have lead particles in them we are down to only 1,163 deer carcasses. Iowa has 55,875 land square miles so this means that there is 1 of these lead contaminated deer in every 49 square miles. Since eagles tend to stay and travel along rivers that would mean 1 contaminated deer in a piece of land that is 1 mile wide by 49 miles long. Even again assuming that eagles find that deer before the other scavengers such as coyotes, foxes, opossums, bobcats, or even crows consumes it that is spreading things pretty thin. Which brings up another point, that if lead poisoning from this source is such a problem, why aren’t we seeing large numbers of these other animals ill or dying from the same lead poisoning? It only seems logical to me.

I am neither for nor against changing some of the ammunition that we use deer hunting, but I don’t feel we should be forced to make that decision based on miss leading information. I believe that the Courier owes it to their readers to research articles a little deeper and not just take misinformation from another publication that originally published the misinformation.
