On the adult tree bright yellow flowers are the first thing in the mangrove tree process. After a month the mangrove seeds drop of from the adult tree, and turn into pods that are anywhere from 6 - 12 inches long. Some pods just sink to the bottom of the ocean because they are too heavy, and some drift until they get waterlogged and then sink. Mangrove trees can grow anywhere from 20 - 60 feet. If the mangrove is in good weather it can grow up to 80 feet.
Mangrove trees are sometimes good and sometimes bad.
They are good because they make shorelines and hold the soil so it won't erode. The bad thing is that mangroves also overpopulate. The worst overpopulation is in the Florida Keys. Scientists think that pods floated from Africa and landed in Florida. Red mangroves are the first type of mangrove to start growing.
