Morels grow abundantly in the two and sometimes three years immediately following a forest fire.[11] However, where fire suppression is practiced, they may grow regularly in small amounts in the same spot year after year. Commercial pickers and buyers in North America will follow forest fires to gather morels. The Finnish name, huhtasieni, refers to huhta, area cleared for agriculture by slash and burn method. These spots may be jealously guarded by mushroom pickers, as the mushrooms are a delicacy and sometimes a cash crop.[10]
Morels have not yet been successfully farmed on a large scale, and the commercial morel industry is largely based on harvest of wild mushrooms
