In 2001, the Science and Technology Department of the Autonomous Region implemented the “Introduction of Trees Research Project” in Nagqu, and experimented to explore the introduction of cold-tolerant trees in alpine regions to improve the ecological climate of Nagqu. In order to ensure the survival rate of introduced trees, a technological route was introduced to introduce tree species from similar climatic zones. In 2002, 300 species of willow shrubs, red willow, alpine willows and alpine leaflets were introduced from Bangor and Jiali successively.
