[124] Tropical rainforests bordering rivers and lakes inhabited by crocodilians are of fantastic relevance to them, creating microhabitats the place they might flourish. The roots in the trees absorb rainwater and bit by bit release it again in the natural environment. This keeps crocodilian habitat moist throughout the dry year while stopping flooding throughout the moist season.[125]
