Is your vegetable patch ransacked in the early morning or your lawn turned over? Coexisting with wild animals can be complicated for owners of houses in the countryside or land on the edge of a forest. While flexible mesh fencing remains the most economical and quickest solution to install for delimiting a plot, its actual resistance to animal intrusion depends on one crucial factor: who are you trying to stop? Naturally, between a wild rabbit and a 100-kilo wild boar, the fencing strategy changes radically!
What type of animal are you looking to repel?
Before planting the first stake, you must observe the tracks. A standard chain-link fence is more than enough to stop small animals like rabbits, hares, or foxes, provided the mesh size is suitable. For these visitors, the mechanical strength of the wire is less important than the size of the diamonds: a mesh that is too wide will let the smallest pests through effortlessly.
On the other hand, when facing large game such as wild boars, roe deer, or stags, the situation changes. These animals possess phenomenal pushing force or impressive jumping ability. Entry-level flexible mesh, poorly tensioned or too thin, will only slow down a determined wild boar that will eventually lift the netting or simply smash through it to make its way.
The resistance of chain-link fencing
Flexible chain-link fencing is renowned for its high elasticity. This characteristic is an asset on uneven or sloping ground, but it can become a weakness when facing wildlife. If you opt for this solution, the choice of wire diameter is non-negotiable. Forget the thin 2 mm wires sold in DIY superstores; to hope to contain somewhat lively animals, it is imperative to aim for professional equipment with a thicker galvanized or plastic-coated steel wire (such as 2.7 mm or 3 mm).
The installation also plays a major role in the solidity of the structure. The installation must be irreproachable: posts sealed in concrete, correctly positioned struts and, above all, perfectly adjusted tension wires and strainers. “Soft” fencing is an invitation to enter for any wild animal that will test the resistance of your perimeter.
The specific case of wild boars
This is the number one enemy of flexible fencing. The wild boar does not jump; it charges or lifts. Against this type of threat, classic flexible mesh quickly shows its limits. If your area is frequently visited by suids, chain-link fencing risks deforming under repeated assaults. For these situations, specific flexible alternatives exist: sheep wire and heavy knotted mesh fencing.
These agricultural fences are designed with high-tensile steel wires and a progressive structure (tighter mesh at the bottom). They absorb shocks much better than residential fencing. Here are the minimum criteria for flexible fencing to resist wild boars:
- Use “high resistance” knotted mesh (minimum 2.5 mm wires).
- Add a row of barbed wire or a very low tension wire flush with the ground.
- Reinforce the attachment to the posts (often wooden stakes or metal T-posts).
When height becomes decisive
If your problem concerns cervids (roe deer, does), the strength of the mesh matters less than its height. A roe deer easily clears a 1.20 m fence. To effectively protect your plantations from these herbivores, your flexible mesh must reach a minimum height of 1.50 m, or even 2 metres depending on the species present in your region.
In this scenario, flexible mesh is an excellent option because it is easy to find high rolls at a reasonable price, unlike rigid panels which become very expensive at these dimensions. The objective here is purely deterrent through height: the animal will not attempt the jump if it perceives the obstacle as too high.
The essential tip: bury the mesh
Regardless of the quality of your flexible mesh, if you do not treat the bottom part, burrowing animals (foxes, badgers, rabbits, and even wild boars) will pass underneath. This is the most common flaw. For optimal protection, it is recommended to bury the bottom of the mesh to a depth of 20 to 30 centimetres, curving it towards the outside of the property (in an L-shape).
If digging a trench along the entire length is impossible, an alternative consists of laying a mesh “skirt” flat on the ground outside, held down by stones or ground staples, which the grass will eventually cover. This prevents animals from scratching at the foot of the fence to create a tunnel.
Should you switch to rigid panels?
If you want to take no risks and aesthetics matter as much as security, rigid mesh panels remain superior to flexible mesh. Non-deformable, they do not fear direct impacts (except very large game at full speed). It is the investment for peace of mind in areas with high pest pressure, but the budget will be significantly higher. Flexible mesh therefore remains the best cost/effectiveness compromise for large plots, provided you choose professional-grade equipment and adapt the installation to the threat.
