Abstract
This research explores ecology of Yarsgumba (Cordyceps sinensis) and its local economical contribution in Manang district of Nepal. The research was carried during the period of 2003 -2004 by direct field inventory and questionnaire survey methods.
The research showed that altitudinal range of C. Sinensis distribution was 4500„b300m with preferable aspect of NW & SW slope in 460 - 650.  The minimum density of Cordyceps sinensis was 1010 individual per hector. Laboratory soil analysis resulted that there was no significant difference in soil nutrients in its habitat. The main associated and feeding plant of moth's larvae was Sunpati (Rhododendron anthopogon). The moisture contain in the Cordyceps sinensis was measured 40-73%. The overall vulnerability of Cordyceps sinensis to harvesting in study area was indicating a high vulnerability and following the traditional harvesting techniques. The study showed that every year approx. NRs 7544500 and 15190900 (US$ 1 = Nepal currency (Nrs) 70) had been earned by local people through selling of Yarsagumba in the year of 2003 to 2004 respectively. While local administrative bodies i.e. VDCs (Village Development Committees) were able to collect NRs 113500 and 554500 as a permit fee in the year of 2003 and 2004 that was less than actual government royalty rate.
 
Key words: Cordyceps sinensis, NTFPs,  Moths,  Mushroom, Hyphae, (US$ 1 = Nepal currency (Nrs) 70)
