Guidelines for Electric fences

It is recommended that a total of 5 lines of electric wire is put in place, in accordance with Life Arctos project guidelines. When constructing the electric fence, the first three lines of wire must be placed 20 cm from each other and start 20 cm from the ground. The last two lines should be at a distance of 30 cm from each other, for a total fence height of 120 cm. This is sufficient to prevent possible intrusion from bears.
A Voltmeter or Joulemeter should be used to measure the efficiency and effectiveness of the system.

The essential components of the electric fence are as follows:

  1. Fence Energiser at least 0.8-1 Joule (2-3 Joules is recommended) and pulse with minimum tension of 5,000 Volts (possibly between 8,000 and 10,000). The energizer can be powered by a home power grid or by 9-12 Volts batteries which work well in conjunction with a solar panel;
  2. Connection bolts from the energiser to the fence;
  3. Earth stake with connective wire to the energiser;
  4. Fence wooden posts 6-8 cm in diameter, placed at the corners of the fencing or at the gate (composed of electric spring gates with insulated handle), best if reinforced by corner counterthrust posts. The posts should be installed 4-5 m apart. Wooden posts should be used for permanent fencing, while for mobile fencing posts made of plastic or other material are acceptable;
  5. Insulators, generally plastic tools to insulate the electric wire from the posts. They are not needed if plastic posts are used;
  6. Fence wire (tape) 16-20 cm wide for mobile fencing and/or metal wiring of 1.5 mm diameter for fixed fencing.
  7. Fence warning sign indicating that electric fencing is in use.

 

Other systems to prevent damage
  • Stables, chicken coops and brick shelters can be made bear-proof by installing metal doors/windows or lockable iron grates and reinforcing roofs (metal fixed to the edges or concrete roofs);
  • Possible use of acoustic deterrents, with the advice of protected areas’ authorities;
  • Bear-proof chicken coops made using metal plates, recently prepared and tested by the Abruzzo, Lazio & Molise National Park according to animal welfare standards.
