Zurich's questionable approach to wild boar

The Zurich hunting administration emphasizes that the wild boar population in Switzerland is growing "ever more" and causing increasing damage in agriculture, even though between 1,000 and 2,000 wild boar are already shot annually in the Canton of Zurich.

The populations are officially estimated at 2,000 to 3,000 animals, with wildlife damage compensation amounting to around 350,000 francs per year. An alleged "growth rate" of up to 300 percent per year is cited as justification for more intensive management.

These numbers alone reveal the fundamental problem: A directionless recreational hunt that has been firing 'from all barrels' unscientifically for years has neither stabilized the wild boar population nor noticeably reduced damage, serving primarily as permanent justification for even more interventions.

The new concept: Fields as war zones, forests as illusion of safety

With the new concept, hunting administration wants to hunt wild boar 'preferably only in the fields', while forests are supposed to serve as supposedly safe refuges. The official message reads: 'Field = danger, forest = safety'. Wild boar are supposed to learn to avoid agricultural crops through targeted harassment shooting in fields. In practice, this means: The night in corn or grain fields becomes the backdrop for shots with exceptional permits and night vision equipment, while the same hunting pressure can later extend into adjacent areas during drive hunts under the justification of 'damage prevention'.

That wildlife become tactically manageable 'opponents' in a spatial planning chess game is not collateral damage of the system, but its core: The landscape is divided along economic interests into zones of management and zones of 'tolerated life'.

Sparing lead sows: Animal ethics or population control?

In the SRF report, a recreational hunter explains that they 'deliberately shoot the young animals and let the older animals with leadership function live', because these are the 'memory of the sounder' and ensure after shootings that the rest of the group stays in the forest. In specialist papers from Canton Zürich, this line is supported: Lead sows should be deliberately spared, while piglets and young animals are to be preferably culled.

What is sold as consideration is in truth a concept of maximum controllability: Young animals are presented as 'digestible sacrifice', the group is deliberately maintained in a structure that reacts to human deterrence and avoids the 'right' areas.

From an animal ethics perspective, the question remains how a system that defines young animals as the primary target category should stand morally higher than classic maximization hunting, just because it proceeds more strategically.

In Canton Zürich, drive and still hunting of wild boar in forests for population and damage reduction is permitted from October 1st to the end of February. Due to increasing agricultural damage, hunting administration relies on intensive movement hunts, use of night vision equipment and preventive measures to regulate the wild boar population.

Technical harassment: Noise, stench and failed agricultural policy

The second pillar of the Zürich model includes technical harassment measures: Electric fences, stinking scents and mobile loudspeaker systems with shooting and scare sounds are subsidized with hundreds of thousands of francs from state coffers. In the last year alone, 200,000 francs flowed into defensive installations and an additional quarter million francs into their maintenance.

These numbers games obscure that the problem is produced elsewhere: Monotonous, high-energy crops are an artificial paradise for wild boar. Fragmented habitats and lacking wildlife refuge zones force animals to repeatedly retreat near intensively managed areas.

Instead of working consistently on the ecologization of agriculture, wildlife corridors and genuine protected areas, focus is once again placed on technology-supported displacement and hunting control.

'Everyone satisfied' except the wild boar

The hunting administration formulates the project's goal openly: If damages decrease with an 'approximately equally high wild boar population,' then 'everyone is satisfied'—meaning recreational hunters, administration, and agriculture. From the wildlife perspective, the assessment looks different: A population that is permanently under fire is trained to a desired behavioral pattern. The root causes of conflict—agricultural policy, spatial planning, recreational hunting, lacking ecological infrastructure—remain untouched.

That the Zurich strategy is now being discussed as a possible 'model for other cantons' primarily shows how strongly hunting and agricultural lobbies jointly define what counts as a 'problem solution.' A model based on refined control rather than consistent protection threatens to become the blueprint for a Switzerland where wildlife is only tolerated where it doesn't economically interfere.

What a truly sustainable wild boar management would be

Wild boar management that deserves this name would not stop at the question of how to deter animals even more efficiently, but would change the rules of the game: Reducing the attractiveness of crops through adapted cultivation and mixed cultures instead of pure deterrence. Expansion of wildlife quiet zones, corridors, and near-natural forest areas where wild boar can live without hunting pressure. Consistent monitoring that captures not only damages in francs, but also stress, injury risk, and ecological functions of wild boar in forests.

However, as long as the question of the legitimacy of recreational hunting itself remains excluded and wild boar, like foxes, are primarily viewed as damage factors and control objects, every new concept will ultimately lead to what Zurich now sells as a 'new path': more technology, more control, more shots, just packaged somewhat better.

What alternative prevention methods against wild boar damage exist

1. Adaptation of crops and areas

In areas with high wild boar pressure, less attractive crops like Sudan grass or cup plant can be grown instead of corn, potatoes, beets, and wheat. Guidelines recommend, for example, not planting corn in forest clearings or directly adjacent to cover structures to reduce the attraction effect on wild boar.

2. Technical barriers

Properly installed and well-maintained electric fences with appropriate wire height and sufficient voltage are considered one of the most effective protective measures, but require 2 to 5 inspections per week. Stable mesh or wildlife fences with solid ground guidance are suitable for particularly sensitive locations, such as vegetable cultivation or vineyards, but are cost and material intensive.

3. Acoustic and visual deterrence

The ZHAW 'wild boar deterrent' works with alarm and warning calls from wild boar as well as variable danger sounds and was able to significantly reduce damage in trials when used strategically during critical phases. Optical stimuli like reflectors, flashing lights, or moving strips can help short-term but often quickly lose effectiveness as animals become accustomed to them.

4. Olfactory deterrence

Strong-smelling repellents or spices like chili are used selectively, for example on posts with soaked cloths, but according to practical reports show very different and usually only short-term effects. Scent agents work, if at all, better as supplements to fences or acoustic systems, not as standalone solutions.

5. Spatial planning, quiet zones and management

Some cantons designate zones with high damage risk and link prevention obligations (e.g., fencing, crop selection) to compensation there. Wild boar management concepts explicitly recommend low-disturbance forest and cover spaces so that wild boar are not forced to systematically move into agricultural areas at night.

6. Combination instead of single measures

Studies and fact sheets consistently conclude that no single method offers absolute protection; however, damage can be significantly reduced when technical barriers, adapted crops, acoustic systems and spatial planning measures are intelligently combined.

7. Basic principles of birth control

Given the fact that recreational hunting does not represent an effective solution, but rather increases risk and undoubtedly causes suffering to animals, IG Wild beim Wild demands the development of effective and ethical methods for fertility control in wild boar, as is done in other countries. The goal is to reduce the fertility of a large proportion of reproducing animals so that population growth is curbed without shooting.
