Trevor(not visible), Marda Norris, and their dog, Clyde, search on the Woodford Truffle farm, for Black Winter Perigord truffles in an orchard of specially-planted oak trees, close to the town of Ceres, in the Western Cape Province, on July 16, 2021. Here, the truffle season lasts between the last week on June to early August. The Norris' are animal trainers that have turned their skills to training dogs to find truffles. - It took six years of trial-and-error, and tonnes of calcitic lime to redress soil acidity, before the first truffles were unearthed. Today the family is South Africa's number one Perigord grower and supplier, with almost 100 hectares of truffle orchards planted on farms across the country. (Photo by RODGER BOSCH / AFP)
