Role of wild boar in the dispersion of truffles


black truffle orchard

Tuber melanosporum orchard

The orchard of this picture is of evergreen oaks mycorrhized with black truffle, located 30km south of Barcelona city, in a place where Tuber aestivum is widely spread.

This plantation was never fenced until this year and it was quite common to see faeces of wild boars over the brules. When we studied those the amount of summer truffle spores was observed. So within the years, when monitoring roots, mycorrhizas of summer truffle start to appear as well, sharing the root system with melanosporum.

This orchard was never irrigated and in the area rains just 450mm a year. Summer truffles start to fruit at year 9, while melanosporum did not fruit yet.

Last weekend during a workshop we organized about how to restore wild truffieres, 42 people attended and the role of wild boars was discussed. Several wild truffle hunters felt that it was better to hunt all boars, if they help to create one truffiere, destroy dozens.

There is a couple of nice papers related to this. They show as the passage of the truffle spores through the gut freed spores from the asci, eroded the walls of free spores and modified their structure but spores were still viable.

P.D. This friday I´ll be flying to USA to attend the truffle growers annual meeting in North Carolina and visiting several truffle orchards. I will try to write some feedback while there.
