Abstract

Commercial value of non-wood forest products is increasing and in some cases can be equal or may even surpass the commercial value of timber. Therefore, an initiative for assessing the potential yield of commercial wild mushrooms in Slovenia arose. We developed empirical spatial models for 27 commercial wild mushrooms. The spatial models have a resolution of 1 × 1 km, assessment for potential production is given in kg × year–1. We verified model accuracy with data from central database of fungi in Slovenia, Boletus informaticus. The accuracy of models range from 60.6% to 99.2%. Estimated potential yield of studied commercial wild mushrooms was 2,869–37,800 tons/year, on average 12,169 tons/year. Potential commercial value of wild mushrooms is estimated at 263–527 €/ha, while overall commercial value of commercial wild mushrooms is estimated at 91–182 million €/year on average. Possible improvements of models for assessing the potential yield of wild mushrooms are discussed.
