A tree nursery was built in North Phyongan Province.

The tree nursery is capable of producing more than 20 millions of saplings of good species every year.

In its afforestation area where over 100 000 trees of various species like Aronia melanocarpa are growing, there are grounds for acclimatization, species-care and seed-selection.

Lawn and shelterbelt inside and around the nursery well match its landscape.
