[124] Tropical rainforests bordering rivers and lakes inhabited by crocodilians are of great importance to them, making microhabitats exactly where they are able to flourish. The roots in the trees soak up rainwater and slowly and gradually launch it back again to the setting. This retains crocodilian habitat moist in the course of the dry year even though protecting against flooding over the damp year.[one hundred twenty five]
