Tropical rainforest trees release a tremendous amount of water through pores in their leaves in a process called transpiration. The pattern of cork development is the main determinant of bark appearance. All tissues outside the cork cambium constitute the outer bark, including the nonfunctional phloem and cork cells. However, fires also can be detrimental to the environment by releasing stored carbon back into the atmosphere, and causing the decades-long loss of a valuable carbon-storage system. moist/dry deciduous forest (monsoon): the length of the dry season increases further as rainfall decreases (all trees are deciduous). But there are other kinds of rainforests, too. RM MAYN5F - Halloween Crab (Gecarcinus quadratus), also called Harlequin Land Crab, on tropical rainforest tree bark in Costa Rica.
