High‐value specialty crops are cultivated under the protection of a forest overstory that has been modified and managed to provide the appropriate microclimate conditions. Shade‐tolerant specialty crops like ginseng (Panax quinquefolium L.), log‐grown shiitake mushrooms (Lentinula edodes (Berkeley) Pegler), decorative ferns and spring ephemerals grown in the understory are sold for medicinal, botanical, food, decorative and handicraft, and landscaping products. Overstory trees are managed for high‐value timber or veneer logs.
