DISTRIBUTION AND COLLECTION PATTERN OF PICRORHIZA KURROOA MEDICINAL PLANT SPECIES OF NEPAL
Medicinal flora is one of the important natural resources of Nepal. Picrorhiza kurrooa (Kutki) is a well-known medicinal herb found in high mountain of Nepal. The Kutki rhizomes have been widely used to cure indigestion problems in traditional medication systems. Very less information is available on its distribution and collection patterns, particularly from high mountain of mid-western of Nepal till date. The present research aimed to explore the distribution of Kutki and assess its collection pattern in Nepal. Primary data were collected through direct field survey and key informant interview. Atotal of 63 plots with each plot size of 5m×5m were laid out in the field to collect data. The stratified systematic sampling with sampling intensity 0.01% was adopted for distribution survey. The results revealed no significance difference in mean number of Kutki with respect to aspect (p>0.05), whereas there is significance difference in mean number of Kutki with respect to elevation (p<0.05). The distribution of Kutki was recorded between 3750m lower plot and 4831m at higher plot. The Important Value Index of Kutki was found 113.59 with relative frequency of 34.44%. The highest density of Kutki (7476.92 per hectare) was found on eastern aspect. Male participation was found higher than the female for collection of Kutki. Scientific harvesting technique should be adopted for sustainable management of Kutki in the study area.
