Most relatively small fruit species are of great environmental importance because they are the food of many endemic birds and mammals, especially in Islands, and premontane and montane forests. Some
Memphis caterpillars feed solely on the leaves of one species of
Ocotea; for example
M. mora feeds only on
O. cernua, and
M. boisduvali feeds only on
O. veraguensis and
Cape parrot.
Ocotea fruit is also consumed by several
Columbiformes such as
Columba trocaz,
Delegorgue's pigeon, African wood pigeon, and American doves. Most of the African tree species are ancient
paleoendemic species, which in ancient times were widely distributed on the continent. Species of
Ocotea can be attacked by various rot-inducing root pathogens, including
Loweporus inflexibilis,
Phellinus apiahynus and
Phytophthora cinnamomi. Some
Ocotea species are used as nesting sites by ants, which may live in leaf pockets or in hollowed-out stems. The ants patrol their host plants more frequently in response to disturbance or to the appearance of insect pests such as grasshoppers. ==Uses==
