The remaining 3 species were first propagated by successful cuttings at Thuy Phin Tung.
The project has invested in construction in Phai Phin Tung house with homeland with an area of 200 m 2 and in early 2006 scientists and technicians have applied technical measures to implement nearly 10,000 species cuttings. Rare and precious conifer trees. The monitoring showed that after 6 months, over 90% of the cuttings were propagated, with roots of 2 to 3 cm in length. By the end of last September, a number of well-developed cuttings were planted under the forest canopy and the remaining stems will be planted in the next spring crop.
