The present study investigated the natural and artificial regeneration of tree species of semi-arid region. All selected sites of this present study were Taj Nature Park, Shajahan Garden, Paliwal Park, Company Garden and Mau Forest in Agra. In this study, natural and artificial regeneration of tree species were categorized according to family wise and habitat wise. According to family wise, maximum artificial regeneration was 17 percent (Fabaceae) and minimum percentage was 7 percent (Meliaceae). In natural regeneration, maximum percentage was 20 percent (Fabaceae) and minimum was 16 percent which belong to Moraceae family. According to habitat wise, maximum percentage of artificial regeneration was 30 (protected area) and in natural regeneration was percent (protected area). Minimum percentage of artificial regeneration was 22 percent area under agriculture land and in natural regeneration was percent under road side plantation. During the study maximum number of tree species were belong to the Fabaceae family. Prosopis juliflora was the dominant species in all selected site which also belong to the fabaceae family. | Diversity and composition of tree species under semi-arid uttar Pradesh, India
