Preliminary investigation on the Distribution of Toona ciliata var. pubescens Resources in PanXi Areas

Toona ciliata var. pubescens is an endemic and rare wood species and is listed as endangered species under state protection (category Ⅱ). Investigation was made on the distribution of toona ciliata var. pubescens resources in Panxi areas and analysis was made of its resource distribution, distribution characteristics and resource stocks. The results showed that Panxi area had fower toona ciliata var. pubescens resources. And they were scattered with about dozens of strains,and were mainly distributed in Dechang,Yanbian and Miyi. Their natural regeneration ability was poorer,therefore some protection measures should be taken.
