RIYADH: Three times more large mammal species once roamed Saudi Arabia than previously thought, according to a new study. The research, conducted in Thuwal, identifies 15 large mammal species that inhabited the Arabian Peninsula over the last 10,000 years. It was published on May 12 in the Journal of Biogeography by researchers from King Abdullah University of Science and Technology and Taibah University. The findings have potential implications for rewilding efforts in the Kingdom, KAUST said in a statement.
