They developed various kinds of forest machines necessary for the cultivation of saplings and established a method for ensuring the tree-planting in all seasons.

The achievements also include the build-up of a database on forest with the aid of satellite image analysis, geographical information system technology, etc., which helps measure all indices ranging from the position of targeted forest district to its geographical feature and climate condition.

Besides, they settled sci-tech problems arising in the restoration of ravaged forest ecosystem and developed an aid information system for mapping up landscape ecosystem to put the study, planning and management of forest resources on a scientific and IT basis.

In the country, an all-people forest restoration drive is going on to turn all its mountains into thick forests.
