Abstract:

In order to facilitate conservation of forest products, a case study focused on monitoring the distribution trend of an economic mushroom, Tuber indicum, was conducted in Yunnnan province. Geographic Information System and species distribution models were employed to establish both current potential habitat and a future projection of T.indicum habitat, through main environmental and climate variables. Results confirmed that combining environmental and climatic factors in the model building process could greatly increase model accuracy. Among tested species distribution models, MAXENT showed the highest performance. At a large geospatial scale, annual precipitation during the wettest quarter, minimum temperature during the coldest month, geomorphology and soil types played the most significant roles in determining T.indicum distribution. Our future projection showed T.indicum shifting northward under both modeled climate change scenarios (A2 and B2), with the B2 scenario having a lower degree of habitat suitability.

Key words: Tuber indicum, Climate change scenarios Species distribution model, Spatial distribution trend, Yunnan Province
