Electric fences against wild boars: protection or danger for deer?

In Waldeck-Frankenberg, the installation of electric fences has become a priority to keep wild boars out of North Rhine-Westphalia that may be infected with African swine fever (ASF). This measure was taken to stop the spread of the disease and protect local agriculture. The fences are primarily placed along the busy federal highways 253 and 236 from Eifa to Bromskirchen. However, despite this initiative, citizens remain concerned about the effectiveness and safety of the fences.

One reader even expressed concern that the fences could not only keep out wild boars, but also deer, which in the worst case could lead to accidents involving wildlife. However, the Ministry of Agriculture in Wiesbaden has justified the existing generators as an “acute measure to contain ASF” and emphasizes that the fences, which are around 80 cm high, are primarily aimed at prohibiting wild boars from leaving infected areas or entering new areas.

The technical details

Electric fences are capable of controlling and containing wild boars, but are not impregnable fortresses. The ministry has found that infected animals often linger near the fences without crossing them. Wild boars can overcome fences, especially if they take a running start. Therefore, external measures such as solid wildlife fences are necessary in cases where electric fences are not sufficient. Secured costs for the construction of these fences amount to around 100,000 euros, supported by the Hessian forestry works.

The existing wildlife crossings were also taken into account during the planning. It is important that deer and deer are able to jump the fences to minimize the risk elsewhere. The local authority has also provided for flexible handling of the fences so that they can be moved at short notice if necessary.

Damage caused by wild boar

Another problem is the damage that wild boar can cause to crops. Tall plants such as rapeseed and corn not only offer pigs protection, but also the opportunity to root and eat, which results in significant commercial losses. A properly fenced area can effectively prevent such damage. In order to be efficient, the electric fence systems used should be put into operation before the crops are high enough so that the damaged ones can stay in the fence itself. According to AKO Agrar, you should consider a pulse energy of over 5 joules in order to withstand heavier vegetation.

The Waldeck-Frankenberg region is therefore faced with a challenge that must balance both nature and agricultural concerns. The use of electric fences is a step in the right direction, but it remains to be seen how effective these measures actually are in averting the risk of contamination from African swine fever.
