In forestry and ecology, understory (or understorey, underbrush, undergrowth) comprises plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor.
 Only a small percentage of light penetrates the canopy so understory vegetation is generally shade tolerant.
 The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth.
 Small trees such as holly and dogwood are understory specialists.
