Sherpa Nima is the man in charge of the massive Sagarmatha National Park which includes Mount Everest.

BBC Wales's Ashleigh Crowter reports

His visit to Cader Idris in Snowdonia National Park was part of a fact-finding mission to discover the techniques for managing an extremely popular attraction and balancing that with Mother Nature.

The scale of the task is enormous - Sagarmatha National Park is eight times the size of Snowdonia, which creates problems in itself.

Thousands of visitors descend on the Himalayas each year, bringing with them huge litter mountains and intruding on local communities.

Sherpa Nima: learning a few tricks of the trade

"We have 3,000 residents living in the boundary of the park and people depend on the area for resources," explained Sherpa Nima.

"They have to depend on the grazing lands for yaks."

Charles Falzon, of the Centre of Protected Landscapes, said the Welsh mountain ranges and the Himalayas had shared interests.

"There are things you notice from places around the world that feature very strongly, cultural and linguistic elements, tribal elements, that impinge on park management."

Sherpa Nima departs Wales on Thursday and will return to the Himalayan monsoon season.
