Raking for truffles is the act of raking the soil of a forest to expose truffles, and then collecting them. This method, used regularly for scientific collections, often yields unripe and immature specimens which may not be suitable for culinary use. Destructive or aggressive raking damages the ecosystem from which the truffles are removed and also negatively impacts the truffle economy, devaluing the quality and reputation of the truffles. Raking can damage other unripe truffles that are not harvested by dislodging them from the support network with their host trees and thus ending their maturation process.
