Activity targets, ideas, etc.

The planted area is a steep slope of 2,200 m above sea level, overlooking Tianchi, the largest lake in Yunnan province. Originally it was a eucalyptus plantation, but the steep slopes were devastated by frequent forest fires due to the high oil content and dryness was widespread. Therefore, developing a large evergreen broadleaved forest by dense and mixed planting, the Miyawaki method of tree planting, could prevent forest fires. At first terraces were formed on the degraded steep slope, and the seedlings grown in the Xishan Forest Farm were planned under the 5-year plan. In the first year, we planted 20,000 seedlings in 2020. It is a place where 18 members have to transport seedlings manually many times over 30 minutes one way and planted on the terrace, but on the last day, in addition to the staff of Xishan Forest Farm, Yunnan Province, the volunteers from the Yunnan Forestry Bureau and Kunming City Forestry Bureau also participated, and these 100 people planted trees on the steep slope.

Other comments

At Yamada Bee Farm, we hold volunteer tree planting trips to China in May and Nepal in July, which also serves as an annual overseas employee training. A five-year project started in this target area in Kunming City, Yunnan Province from 2020, but due to the worldwide spread of the new COVID-19 infection, it had to be canceled in 2020, and 20,000 planting by only Chinese people was required. Over the next five years, we plan to develop evergreen broadleaved forests on this degraded land and stop forest fires on the green mountains.
