MAXENT MODELLING OF THE POTENTIAL DISTRIBUTION OF GANODERMA LUCIDUM IN NORTH-EASTERN REGION OF ROMANIA

Abstract

Ganoderma lucidum is one of the most valued mushrooms in the World, because of its medicinal properties. In the context of North-Eastern Region’s development, any forest product could have a valuable contribution. Therefore, it is important to understand the mushroom’s ecology and generate a map of its optimal distribution. For this, we used one of the most performant species distribution models available – Maxent, field occurrences and climatic-topographic-biotic variables. After multi-collinearity testing and step-wise Maxent modelling, we came to an end with a 0.8 final model based on two predictors. Thus, in the region, the optimal habitat distribution is found in oak, beech, riparian or mixed forests bellow approximately 800 m altitude. The species can be found in almost all forests across lowland, colline and submontane regions according to tree host presence. The approach could be promising for other fungal species for the sustainable development of the region.
