Mycoforestry is an ecological forest management system implemented to enhance forest ecosystems and plant communities through the introduction of mycorrhizal and saprotrophic fungi. Mycoforestry is considered a type of permaculture〔Friedman, Zev. (Digging In. ) ''New Life Journal.'' 1 May 2009.〕 and can be implemented as a beneficial component of an agroforestry system. Mycoforestry can enhance the yields of tree crops and produce edible mushrooms, an economically valuable product. By integrating plant-fungal associations into a forestry management system, native forests can be preserved, wood waste can be recycled back into the ecosystem, planted restoration sites are enhanced, and the sustainability of forest ecosystems are improved. Mycoforestry is an alternative to the practice of clearcutting, which removes dead wood from forests, thereby diminishing nutrient availability and reducing soil depth.〔Dahlgren, R. A.; Driscoll, C. T. (The effects of whole-tree clear-cutting on soil processes at the Hubbard Brook Experimental Forest, New Hampshire, USA. ) ''Plant and Soil.'' Volume 158, Number 2 / January 1994.〕 ==Selection of fungal species== According to Paul Stamets, the first principle for the creation of a mycoforestry system is to utilize native fungal species. Implementing a mycoforestry system provides the potential of improving restoration efforts and the possibility of economic gain through mushroom cropping and harvesting. However to utilize native fungal flora, first the relationships between present fungal species and growth substrate, and habitat need to be studied. A simple way to introduce a mycoforestry system and enhance out-plantings for crops and forest restoration sites is to "use mycorrhizal spore inoculum when replanting forest lands"〔 For this process it is best to match native trees with native mycorrhizal fungi. This method keeps and will promote the functioning of the native ecosystem, and native biodiversity. It is assumed in a functioning forest ecosystem an underground mycelial network persists even if no fruiting bodies are visible.〔Frankland, Juliet C. (All you ever wanted to know about Mycelium. ) ''NWFG Newsletter.'' April 1997. (ISSN 1465-8054) Print.〕 A period of disappearance of mushrooms from an area should not cause alarm. In order to trigger the formation of fruiting bodies, many fungal species require specific environmental conditions. Most species of fungi do not fruit year round. Mycoforestry is an emergent scientific field and practice.〔 Until broadly standardized protocols are created and perfected, the collection of both current and historical ecological site conditions will improve the success of the project.〔 Therefore, a survey of fungal relations at the site under both prime and poor conditions is beneficial to implementation of a mycoforestry system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mycoforestry」の詳細全文を読む スポンサード リンク
