The first presentation, given by Reinhard Huber (HBLFA Raumberg-Gumpenstein), explained how a modern electric fence is constructed and how it functions. In addition to the correct and efficient construction of the fences, potential sources of error during construction and operation were also addressed. The central topic is proper grounding, adapted to the power output of the electric fence energizer, the materials to be used, and the necessary distances during construction and anchoring of the grounding system.
The next article presented the practical application of an electric fence system for livestock protection on the Grabneralm. Wolf attacks occurred there in 2021, which is why the sheep flock was cared for by a shepherd and protected with an electric fence in 2022. This involved both keeping the sheep in paddocks and herding them during the day and housing them in a secure night pen at night. In addition to the animals' performance, the study also recorded the working hours and costs associated with herding a small flock of sheep.
Albin Blaschka from the Austrian Center for Bear, Wolf, and Lynx explained the advantages and disadvantages of managed grazing on alpine pastures and meadows. With declining livestock numbers and climate change, sufficient water supply usually means that grazing animals have enough forage. However, selective grazing leads to a deterioration of the pasture in the medium term, potentially resulting in scrub encroachment. Managed grazing allows for the gradual utilization and preservation of less productive areas, leading to better utilization of forage areas. Having a herder present at all times offers additional benefits for animal health and enables the implementation of herd protection measures when necessary.
The next item on the agenda featured presentations from Gallagher, Patura, and Fency, showcasing their latest products and demonstrating their practical applications. Various electric fences were set up in the open area, and different systems were demonstrated: mobile fencing with netting and a smart fence system, various energizers, and a fence with T-posts. Johann Steinbrecher, head of the technical center, also explained the classic electric fence with wooden posts, which has been in use for 15 years. Under the expert supervision of the fence builders, visitors were able to practice the techniques they had learned in constructing different parts of an electric fence (driving a T-post with a post driver, tying insulators, installing fence tensioners, etc.) and gather valuable practical tips. Finally, the Landmarkt Technical Center Bad Mitterndorf invited participants to enjoy refreshments and snacks, where further technical discussions took place.
