Crown shyness - Wikipedia

Crown shyness (also canopy disengagement , [1] canopy shyness , [2] or intercrown spacing [3] ) is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps. [4] [5] The phenomenon is most prevalent among trees of the same species, but also occurs between trees of different species. [6] [7] There exist many hypotheses as to why crown shyness is an adaptive behavior , and research suggests that it might inhibit spread of leaf-eating insect larvae . [8]
