Abundance, distribution, and growth characteristics of three keystone Vachellia trees in Gebel Elba National Park, south-eastern Egypt

Abstract This study was conducted to evaluate the abundance and distribution pattern of three keystone Vachellia taxa in wadi Khoda and wadi Rahaba, Gebel Elba National Park, a protected area in south-eastern Egypt. These taxa included Vachellia tortilis subsp. tortilis, Vachellia tortilis subsp. ra...
