Do hunters conserve nature? This seemingly controversial issue seems to be a source of never-ending debate. I recently found a text discussing this issue, published in the “Finnish Nature” (Suomen Luonto) magazine as early as 1944. While conservationists and hunters may sometimes be in direct conflict, some shared targets were recognized already in 1944.
O. Hytönen (1944) raised the very same observations that are still apparent. Although hunters kill animals, prey animal populations should not be eradicated by responsible hunting practices. Some hunting actions are straightly connected to nature conservation, such as feeding animals during harsh winters, habitat management and predator control. Currently discussed effect of trophy hunting as an important conservation tool in development countries is an example of an indirect connection: by paying for hunting permits hunters help to maintain local animal diversity. As noted in a recently published paper, banning of trophy hunting can lead to exacerbating biodiversity loss.
In 1953 “Finnish Nature” (Suomen Luonto) published another text on the subject, this time written by G. Bergman. Bergman wrote that the relationships between hunters and conservationists has not always been smooth in Finland, or in other Nordic countries, while no benefits could be gained from these conflicts. Bergman noted that modern game management has several shared principles with nature conservation. He also pointed out that nature conservation and hunting have successfully been managed together in the US. As during Bergman’s times, Europe is still somehow on separate paths, and the situation has become particularly inflamed in some countries. Ironically, Bergman wrote that if we refuse to understand the interests of others, nature conservation aims may be disturbed.
The good old American way
What were the good manners already mentioned by Bergman in America? Maybe he meant the Federal Duck Stamp system established already in 1934. All US hunters must buy a Duck Stamp on a yearly basis, however, whoever can get one. With this small cost the buyers contribute to bird habitat conservation. The US Fish and Wildlife Service advertises that the stamp is “among the most successful conservation tools ever created to protect habitat for birds and other wildlife”. About 1 500 000 stamps are bought yearly, and 98% of the profits are given to the National Wildlife Refuge System for wetland conservation.
Another traditional American actor smoothly combining conservation and hunting is Ducks Unlimited (DU), founded by a group of hunters in 1937. DU targets habitat conservation, and is now claimed to be the world’s largest and most effective private waterfowl and wetlands conservation organization according to their website. Most DU members are still hunters.
The land of a thousand lakes
Wetlands have been destroyed for a long time due to differing human interests, also in Finland. Some areas have been lost altogether, while some have lost their value due to e.g. vegetation overgrowth. We still have many lakes left, but shallow eutrophic lakes – the waterbird lakes – are the ones that have been lost most often. Hunters are a group with an interest to construct and restore wetlands. According to a report by the Finnish Wildlife Agency, hunters have constructed or restored about 2 000 wetlands during the past decades. In addition to benefitting game animals, the entire ecosystem benefits. Wetlands also offer several other ecosystem services, including water purification and erosion control.
Sometimes hunting itself supports animal populations. For example, hunters can help to maintain animal communities through ecosystem engineering pushed by hunting and the co-evolution of animals and humans. In 2013 a scientific paper showed that in Australia Aboriginal hunting was one of the cornerstones supporting monitor lizard populations. Monitor lizards occur most densely in areas where they are hunted, because of the hunting method used; the burning method creates a patchy mosaic of regrowth in the landscape. In areas with no hunters, occasional lightning strikes burn land in a more homogenous way, and thus also lizards are scarcer. The same practice might also benefit several other desert species. However, in many cases Aboriginals have lost their traditional hunting possibilities, and the loss of these traditional practices sustaining habitats might have contributed to decreasing populations of several desert animal species.
While the debate between hunting and nature conservation has already lasted a long time, and is still on-going, common targets have been raised throughout the process by cooperative actors of both sides. There has always been, and currently still are, differing hunting methods for concerning conservational effects, but it is self-evident that all these practices are not against conservation targets.
