In Saudi Arabia, Al-Baha region is considered the most vulnerable to changes in community structure and biodiversity due spread of invasive plants.This study was designed evaluate diversity plants across six dam areas (Medhas, Aljanabeen, Alaqiq, Arada, Alahsaba Olib).Twenty were reported representing 17 genera 10 families; 35% them from American region, while 55% therophytes Asteraceae prevalent family.Species richness ranged 4 13 per area, higher Medhas lower Olib areas.Argemone ochroleuca which abundantly distributed all had greatest potential invade this area.The evenness value for area (0.92) markedly high since it close one.A level plant observed Aljanabeen areas.This result confirmed by highest Shannon (2.19), Simpson (0.88), Brillouin, (2.16), index values Margalef (1.86), Menhinick (0.52), Fisher's alpha (2.31) area.Plant invasion correlated with soil physical chemical variables elevation gradients.Canonical correspondence analysis revealed that total organic matter, electric conductivity, key active environmental factors studied areas.
