Abstract
Alien animals cause drastic and negative impacts on biota and ecosystems. The feral donkey Equus asinus is an invasive alien species in Saudi Arabia. Damage to farms and plants consumed by feral donkeys was studied between Al-Ula and Al-Wajh governorates to spot their harmful effects in this region and propose possible solutions to the problems they caused. Surveys and direct interviews, and conversations with farmers and villagers were the selected methods used to collect information. As a result, prevention and management actions were suggested to decrease the number of feral donkeys. In addition, a good investment potential was proposed to get some benefits from them.
