Abstract
ABSTRACTBlack truffle (Tuber melanosporum Vittad.) has very specific environmental requirements. We integrated these requirements in a geographic information system and weighted them depending on their importance for the presence of the species, based on previous field and laboratory experience. The parameters considered were divided into three groups: (i) topographic; (ii) climatic and (iii) edaphic. A multicriteria analysis was used to develop a final potential habitat map, and filtering it by land uses we produced the cultivation potential map. The result of this work is a 1:275,000 map of Zaragoza province (Spain) that integrates all mentioned maps. This is a practical tool for territory managers, farmers and researchers who will be capable of identifying the better cultivation zones in the Zaragoza province with this map.
Highlights
Black truffle (Tuber melanosporum Vittad.) cultivation is one of the most valuable emerging agroforestry activities throughout the Mediterranean area, it is not yet completely domesticated
We analysed the natural factors of black truffle presence in Zaragoza (17,274 km2) province, an area with promising internal cultivation potentiality because of its edaphic and climatic characteristics (Palazón, Delgado, Barriuso, Sánchez, & Asensio, 2008)
This region borders the province of Teruel to the south, one of the most productive areas of black truffle in the world with about 4000 ha of plantations (Reyna & García-Barreda, 2014)
Summary
Black truffle (Tuber melanosporum Vittad.) cultivation is one of the most valuable emerging agroforestry activities throughout the Mediterranean area, it is not yet completely domesticated. We analysed the natural factors of black truffle presence in Zaragoza (17,274 km2) province, an area with promising internal cultivation potentiality because of its edaphic and climatic characteristics (Palazón, Delgado, Barriuso, Sánchez, & Asensio, 2008). The final aim is to produce a map of potential cultivation in order to identify the most suitable areas based on environmental requirements of the species.
