A total of 20 butterfly species belonging to two Nymphalidae and Pieridae families were recorded. The Various diversity indices, i.e. Simpson Index (0.09), Shannon Winner Index (3.05), Berger- Parker Dominance Index (0.06), Margalef &rsquo;s Index (3.27), Menhinick Index (0.89), Buzas and Gibson's Index (0.96) were also calculated. The Lepidoptera diversity decreased along elevation gradient (1,400 &ndash; 2,600 m asl). This study will help in understanding the total energy flow in the ecosystem and in ensuring the soil fertility of Tolipir National Park.</p> Biodiversity, Conservation, National parks, soil fertility Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2015-JAPS-610
