In drier, temperate deciduous forests a thick bark helps to limit moisture evaporation from the tree's trunk. why is tree bark thin in the tropical rainforest? It is unlikely that buttresses provide aeration, as they have different anatomy from pneumatophores and as some species have both buttresses and pneumatophorese.g., Pterocarpus officinalis and bald cypress, Taxodium distichum. Height growth is diminished whenever buttressing is developed, suggesting that the carbon resources of the tree are reallocated as a response to environmental conditions.
