Coastal dry woods are an unique habitat because of their high levels of ecosystems (containing many species found nowhere else). Adaptations in plants and animals are widespread due to this forest’s distinct dry season. To conserve water, many tree species are deciduous, which means they lose their leaves in the early part of the dry season. It expands when it rains so that the plants may withstand the dry season with their waxy leaves and tissues. Because the stored water is needed during the dry season, many dry forest plants produce poisonous spines to protect the water source.
