very very sad news.. hope they are all safe...Along with Dr. Gurung..Dr Tirtha Man Maskey the man behind perservation of ghariyal and Rhino was also on the chopper. He is the one who has struggled for many years to turn Nepal's parks into what they are today. His contribution to Nepal has made a significant impact on Nature conservation... Let us all hope for the good news. Lets pray for miracle to happen...
