Despite years of back-to-back drought worsened by a warming climate, the grass here seems to be improving. Luark and Wallner are crediting a new technology that allows them to move cattle without physical fences.
Under the system, cows are outfitted with shock collars — similar to ones for training dogs — that use GPS and reception towers to form a virtual fence controlled by a computer. The technology from Vence (for “virtual fence”) makes it easier for Luark to move his cattle and determine how long they should spend grazing in a particular spot.
