In Mubon-ri, Choe Ryong Hae learned in detail about how it has preserved soil and solved the issue of firewood by planting fast-growing poplars.

Looking round the mother tree nursery of the forestry management station of the county, he gave a pep talk to its employees who are making great contributions to the forest restoration campaign by growing many saplings, and called for putting the production of saplings on a higher scientific, industrialized and intensive basis.

He gave field officials the instructions on such issues as letting every ri properly build its own tree nurseries, boosting the rate of rooting by fertilizing and tending them in a responsible manner and designing the cyclic felling in firewood forest in a scientific way as required by the Party policy.
