Hunting and Biodiversity: Does Hunting Protect Nature?

"Recreational hunting protects biodiversity" is a statement that works well politically. It sounds modern, scientific and responsible. Hunting associations repeat it at every opportunity: in press releases, in consultation responses, in conversations with authorities. JagdSchweiz explains on its own website that hobby hunters make "an important contribution to biodiversity protection". This sounds like evidence. But upon closer examination, it becomes apparent: what is marketed as nature conservation service is a usage practice that gives itself an ecological label.

Biodiversity is more than the number of animal species in an area. It encompasses genetic diversity within populations, the diversity of habitats, and the functionality of ecological systems: insects, soil organisms, fungal networks, plant communities, water quality, structural richness. The federal biodiversity strategy identifies the greatest threats to biodiversity in Switzerland: habitat loss through settlement growth and infrastructure, intensive agriculture, pesticides, light pollution, climate change and lack of connectivity. Recreational hunting does not appear in this analysis as a protective factor. It is also not a threat factor in the narrow sense, but it is equally not the instrument it sells itself as.

Anyone who takes biodiversity seriously must protect habitats, promote connectivity and reduce human pressures. Recreational hunting does none of this. It annually removes around 76,000 wild ungulates and 22,000 predators from ecosystems, alters social structures, generates hunting pressure and behavioral changes, and ties every removal to politically determined quotas rather than ecological targets. This may have localized effects. But constructing blanket nature conservation legitimacy from this is not scientifically tenable.

Selectivity and social structures: When culling deforms populations

Recreational hunting is rarely ecological fine-tuning. It follows shooting plans, traditions, permit rights and individual preferences. Some animals are preferentially killed, others spared. This alters age and gender structures within populations and can have far-reaching consequences for species with complex social behavior.

In red deer, for example, studies show that targeted removal of experienced lead animals destabilizes migration patterns, spatial behavior and reproductive dynamics. Young, inexperienced animals assume roles for which they are not socially prepared. The result: disorganized groups, increased movement unrest and heightened browsing pressure, because the animals behave differently in their retreat areas than in stable social units. Prof. Dr. Josef H. Reichholf describes the mechanism thus: «Hunting does not regulate. It creates excessive and suppressed populations.» Population ecology shows that intensive hunting triggers compensatory reproductive increases: earlier sexual maturity, larger litters, higher survival rates in offspring. The more intensively hunted, the more offspring emerges.

In foxes, the effect is particularly well documented. In heavily hunted populations, the average age drops drastically, territorial structures collapse and the reproductive rate rises. In Switzerland, approximately 20,000 red foxes are killed annually, yet populations remain stable or grow. Luxembourg has protected the fox since 2015 and has since documented no population explosion, but rather a 20 percent reduction in fox tapeworm infection rates, because stable social structures slow the spread of parasites.

What the recreational hunting lobby calls 'population regulation' is in truth a periodic wildlife harvest that frequently stabilizes or enlarges the population while destroying social structures that are essential for ecosystem functioning. This is not biodiversity protection. It is an intervention that replaces ecological complexity with simplified shooting quotas.

Indirect Effects: When Hunting Pressure Disrupts Nature

Recreational hunting influences not only how many animals live in an area, but especially how they behave. Under hunting pressure, wild animals profoundly alter their spatial behavior: They avoid open areas, retreat into dense forest stands, and shift their activities to nighttime. Prof. Ilse Storch, head of the Wildlife Ecology and Wildlife Management chair at the University of Freiburg, states clearly: «Humans are perceived as a threat.» This is not habituation, but a biologically grounded stress response to a lethal threat.

These behavioral changes have consequences that extend far beyond the individual animal. When roe deer and red deer avoid open areas and concentrate in forests, browsing pressure on young trees, shrubs, and ground vegetation increases there. What recreational hunting describes as «forest protection» thus partly produces exactly the browsing damage it allegedly combats: because driven hunts panic wild animals into those refuge areas where they then consume available vegetation under heightened stress. The connection is scientifically well documented: A 14-year study of blood samples from hunted and naturally deceased ungulates for cortisol concentration shows that animals from driven hunts exhibit drastically higher stress hormone levels than those that died undisturbed.

The shift to nocturnal activity has additional consequences: When wild animals move their movements into darkness, the risk of wildlife accidents in road traffic increases. A US study in Wisconsin proved that the return of wolves, which naturally regulate wildlife behavior, reduced wildlife accidents by 24 percent. Recreational hunting, however, generates exactly those flight movements and stress reactions that promote wildlife accidents, then uses the resulting accident statistics as an argument for more culling. It is a self-legitimizing cycle.

For biodiversity, these indirect effects are severe. When hunted game avoids certain areas, its ecological contribution is missing there: seed dispersal, vegetation mosaic through selective feeding, trampling effects that create microhabitats. The landscape becomes more uniform instead of more diverse. Recreational hunting changes not only populations, it changes landscapes.

Feeding and Population Support: When Nature Conservation Becomes Production

In many hunting areas, wild animals are fed, officially out of «necessity» during harsh winters, but in practice often for population support or to direct wild animals into certain areas. Feeding fundamentally alters natural selection mechanisms. What nature regulates through food scarcity, disease, and winter mortality is undermined by human intervention: More animals survive the winter than the habitat can naturally support.

The consequences for biodiversity are documented. Feeding sites create unnatural concentrations of many animals in confined spaces. This promotes the transmission of parasites and diseases, increases browsing pressure in the immediate vicinity, and disrupts natural spatial distribution. Studies on tuberculosis spread in deer in alpine areas show that feeding sites function as hotspots for disease transmission. What is communicated as an animal welfare measure harms the health of the population.

The biodiversity contradiction is fundamental in nature: feeding maintains populations at a level that would not exist without human intervention. These artificially elevated populations then create the browsing pressure that serves as an argument for more culling. Recreational hunting thus creates its own regulatory need. Those who feed wild animals in winter so that enough culling is possible in autumn are not conducting biodiversity policy, but population management, a production logic that has nothing to do with nature conservation.

A biodiversity strategy worthy of the name relies on natural winter mortality as a regulatory element, on habitat-appropriate environments that enable wild animals to survive even without feeding, and on a wildlife policy that does not depend on culling numbers and hunting license sales.

Predators instead of recreational hunting: What natural regulation achieves

The most effective regulators of ungulate populations are not hobby hunters with rifles and culling plans, but predators: wolf, lynx, bear. These species have shaped the ecosystems in which biodiversity emerges for thousands of years. Their return to Switzerland is one of the most important developments of recent decades from a biodiversity perspective.

The ecological impact of predators extends far beyond mere reduction of prey numbers. The 'Landscape of Fear' effect describes how the mere presence of wolves changes the spatial behavior of deer and roe deer: The animals avoid certain areas, change locations more frequently and spend less time in sensitive places. Vegetation in these areas can recover: young trees grow back, riparian vegetation stabilizes, new habitats for insects, birds and small mammals emerge. In Yellowstone National Park, this cascade was scientifically documented after wolf reintroduction in 1995: Changed elk movements led to regeneration of willows and aspens, which in turn strengthened beaver, fish and songbird populations.

Comparable patterns are emerging in Switzerland. In Graubünden, the wolf's return has already helped reduce roe deer populations in individual areas and reduce special hunts. The forest association welcomes this development because natural browsing pressure decreases. The lynx has demonstrably reduced roe deer populations in regions like Toggenburg, Uri, Bernese Oberland and Solothurn. A study of 3,000 wolf scats in Germany found that over 96 percent of prey remains came from roe deer, red deer and wild boar, precisely those species that recreational hunting claims to 'regulate'.

The crucial difference: predators regulate selectively, continuously and without the destabilizing side effects of human hunting. They preferentially take sick, weak and inexperienced individuals. They create no seasonal stress peaks. They require no culling plans, no license sales and no politically negotiated quotas. The increasing wolf culls in Switzerland thus counteract precisely that natural regulation which would be most effective for biodiversity. Those who want biodiversity must accept predators, not fight them.

Browsing is not everything: Why the biodiversity debate falls short

The forest-wildlife conflict dominates public debate about recreational hunting and nature. Too many deer eat too many young trees, according to the standard argument. The solution: more culling. What is overlooked: browsing damage is a symptom, not a cause. And biodiversity is much more than the question of whether a particular young tree survives.

The greatest drivers of biodiversity loss in Switzerland are not deer and stags. They are habitat loss through urban growth and infrastructure, intensive agriculture with pesticide and fertilizer use, fragmentation of habitats by roads and fences, climate change with shifts in vegetation zones and phenologies, as well as light pollution that disrupts nocturnal insects and their food webs. In Switzerland's Red List, over one-third of all studied species are classified as threatened. Species loss primarily affects insects, amphibians, reptiles and plants—groups that are not addressed by recreational hunting at all.

Browsing pressure itself has multiple causes that go beyond the mere number of deer: Monocultures in forestry offer less alternative food than structurally diverse mixed forests. Climate stress weakens young trees and makes them more vulnerable. And hunting-induced retreat of wildlife into forests concentrates browsing pressure on smaller areas. The Swiss National Park has shown for over a hundred years that forests can exist and naturally regenerate without recreational hunting when habitats are intact and natural dynamics are permitted.

Biodiversity protection requires a holistic perspective: forest conversion toward climate-resilient mixed forests, reduction of pesticides, habitat connectivity through wildlife corridors, promotion of predators, removal of migration barriers and protection of wetlands, dry grasslands and forest edges. None of this requires an armed militia with hunting licenses. Those who reduce the biodiversity debate to the forest-wildlife conflict and present recreational hunting as a solution deflect from the actual causes and serve a narrative that primarily secures the continuation of recreational hunting, not the continuation of biodiversity.

Geneva's Counter-Example: Biodiversity without Recreational Hunting

The strongest empirical argument against the thesis 'recreational hunting protects biodiversity' lies in the heart of Switzerland. The canton of Geneva abolished militia hunting by popular vote in 1974. Since then, wildlife management has been conducted exclusively by state-employed wildlife wardens, according to clear criteria, transparently and without trophy logic.

The biodiversity record after over 50 years is unambiguous: Fauna Inspector Gottlieb Dandliker describes a strong increase in bird population from a few hundred to 30,000 winter visitors. Throughout the canton, a network of different habitats has emerged in which a variety of partly rare animals and plants have found homes. A long-term study documents the strong increase in biodiversity. Wildlife uses Geneva as a refuge from surrounding hunted areas. The population benefits from more frequent, less stressful nature observations and higher social acceptance of wildlife in urban areas.

The Geneva model not only refutes the claim that recreational hunting is indispensable for biodiversity. It also shows that the opposite is possible: more biodiversity without recreational hunting. Abandoning seasonal hunting pressure, drive hunts and battues, feeding stations and systematic removal of predators creates conditions under which natural processes can become effective again. Geneva is living proof that wildlife policy without militia hunting not only works, but delivers even better results for biodiversity.

What would need to change

Biodiversity strategy without hunting dependency: Nature conservation must focus on habitat protection, connectivity and reduction of human pressures, not on annual hunting quotas. Recreational hunting must not be considered a standard instrument of biodiversity policy. Model motion: Wildlife corridors and quiet zones
Promoting predators as natural regulators: Wolf, lynx and other predators are the most effective instruments for regulating ungulate populations and promoting natural ecosystem dynamics. Their return must be politically supported rather than undermined by culling.
Independent biodiversity evaluation of recreational hunting: Scientifically independent studies are needed on whether and how recreational hunting actually influences biodiversity in Switzerland, both positively and negatively. The previous self-assessment of recreational hunters as «nature conservationists» is insufficient as evidence. Model motion: Transparent hunting statistics
Ban on wildlife feeding outside clearly defined emergency situations: Population support through feeding contradicts a biodiversity strategy that relies on natural processes. The definition of «emergency situation» must be scientifically justified and regulated uniformly at cantonal level.
Decoupling of forest-wildlife conflicts and recreational hunting legitimation: Browsing problems are primarily a result of habitat loss, climate change and hunting-induced behavioral changes. Biodiversity policy must address these causes instead of reflexively calling for more culling.

Arguments

«Recreational hunting protects biodiversity.» Biodiversity depends primarily on habitats, connectivity, soil life, insects and natural processes. Recreational hunting selectively intervenes in individual species, changes social structures and creates behavioral changes through hunting pressure that generate new conflicts. A blanket nature conservation legitimation for a recreational activity that kills animals according to a culling plan is professionally untenable.

«Without recreational hunting, the forest would be destroyed by wildlife browsing.» Browsing is a real problem, but the causes lie deeper: habitat loss, climate stress, monocultures in forestry and hunting-induced retreat of wildlife into forests. Studies show that intensive hunting pressure drives wildlife precisely where they cause the greatest damage. The Swiss National Park has shown for over a hundred years that forests can exist without recreational hunting.

«Predators alone cannot regulate wildlife populations.» Predators have regulated ungulate populations more effectively than any human culling plan for thousands of years. The return of wolves in Graubünden has reduced the roe deer population and reduced special hunts. In Wisconsin, wolf return reduced wildlife accidents by 24 percent. The claim that predators «are not enough» serves primarily to maintain the recreational hunting system.

«Feeding is necessary for wildlife to survive winter.» Wildlife feeding alters natural selection mechanisms, promotes disease transmission and parasites, leads to unnatural concentration of many animals in few locations and promotes populations beyond the level that habitat can naturally support. Nature has functioned without human feeding for thousands of years. Feeding often serves not animal welfare, but population support for the next hunting season.

«Biodiversity requires active management, not doing nothing.» Active management means protecting and connecting habitats and reducing human pressures, not routinely killing animals. Wildlife ranger structures based on the Geneva model, predator promotion, biotope care and wildlife corridors are active management. Recreational hunting with trophy logic, shooting quotas and license sales is a utilization system, not a nature conservation concept.

The claim that recreational hunting protects biodiversity does not withstand professional scrutiny. Biodiversity emerges through intact habitats, natural processes and functioning food webs, not through shooting quotas and license hunting. A nature conservation policy that treats recreational hunting as a standard instrument confuses utilization with protection.
