Abstract:

In order to promote the development and protection of wild edible resources in Chengde Plateau, especially wild commercial fungus, from 2007 to 2010, the author studied wild edible mushrooms which were collected from forests of pine in Chengde Plateau and adjacent regions. In total, 102 taxa belonging to 31 genera of 16 families were identified, among which 15 taxa in 4 genera of 6 families were commercial mushrooms traded in the local markets. The results showed that, with the implementation of measures including grazing ban, logging ban, returning farmland to forest and so on in Sanhanba, ecological environment was gradually improved. The diversity of wild edible mushrooms from pine had a overall upward trend, while the variety and quantity of wild commercial fungi appeared a decline, especially the Lepista caespitosa had reached the edge of endangered species. It was appealed for taking some effective exploitation and conservation measures.
