Prunus mira Koehne and Prunus armeniaca L. in Nepal Himalaya: distribution, use, and conservation

Prunus mira and Prunus armeniaca are the two prominent fruit-bearing plant species in the Nepal Himalaya and possess notable ethnobotanical significance. These two species represent relatively unexplored edible resources in Nepalese flora and are characterized by the presence of glands in their leaves and fruits with stony endocarp. Subsequent to an on-site investigation and personal interviews with 90 respondents, we accumulated comprehensive data related to folk nomenclature, distribution, ethnobotanical, threats, and conservation status of P. mira and P. armeniaca in the Nepal Himalaya. We recorded a total of nine vernacular names for P. mira and six for P. armeniaca. P. mira was found to be distributed in six districts at an elevation of 2200-3600 m and P. armeniaca in nine districts within the range between 1500 and 3500 m. The use reports of P. mira were more than 454 and that of P. armeniaca were 367 with significant difference (W = 5485, p < 0.05). Site-wise, the use report of P. armeniaca was significantly different (chi(2) = 44.317, df = 5, p < 0.01) but the use report of P. mira was less significant. Both species are economically valuable, growing in the farmyards and homestead areas. However, the modifications to agricultural practices posed an additional threat to the survival of these species. Establishing contemporary harvesting infrastructure, developing sustainable marketing goods, and disseminating conservation awareness throughout the Nepal Himalaya areas are necessary to ensure their preservation.
