Shade-Intolerant Species
Shade-Intolerant Species : Plant species that require open, sunny conditions for optimal growth, and will grow poorly, if at all, in shady conditions, although they may colonize gaps. Typically, easily dispersed plant species that can invade a disturbed site and grow rapidly to form the first forest community in the next successional sequence (e.g., many pine species, larch, alder, and cottonwood)
