A study into potential natural vegetation and creating an action plan for planting suitable trees in Yunnan Province

Activity grant

Project Description

The mountains of Xishuangbanna Mangao Nature Reserve in China's Yunnan Province are becoming bare due to excessive forestry development in the region, resulting in severe water pollution in Lake Dian, the province's largest lake which is located in Kunming, and there is an urgent need for tree planting initiatives. Following an appeal for support from an environmental development foundation based in Yunnan, this project will formulate a 'Miyawaki method' action plan aiming to conserve the environment, restore vegetation, and recharge groundwater. This method involves selecting plants based on potential natural vegetation, and the project will look to regenerate the forests quickly through close, companion planting. Specific measures will include dispatching a research team, including Dr. Miyawaki, to research the potential natural vegetation of two areas, identifying suitable plant species, and formulating a planting plan. China-Japan academic exchange symposiums will also be held to foster academic exchange and technical cooperation between Chinese and Japanese parties. This will ensure that Miyawaki method reforestation techniques are passed on to local people with the hope that it will lead to planting activities on an appropriate scale to ensure quick reforestation and water purification in the region.
