The absence of predators is noticeable this winter. Some bordering fields use poison to kill predators and in RASA you can no longer see the foxes or the wildcat that kept the hare population at bay. Herbivores have greatly increased in number and when the summer pastures were lost they began to destroy the forestation. Willows and tamarisks are cut and eaten, unfortunately foreseeing their loss. Because RASA has more than two thousand units planted, it is very difficult to protect each one with plastic wrap.
