The General Bureau of Forestry under the Ministry of Land and Environment Protection took a detailed step for provinces, cities and counties to secure seeds of good tree varieties on a mass scale during this year's autumn land management campaign.

As a result, Ryanggang, Jagang, Kangwon and other provinces and Pyongyang City collected in a short period many seeds of various trees, including pine-nut tree.
