It re-quires a considerable degree of light, however, and prefersa moist seed bed. The natural distribution of the seedtakes place for several hundred feet from the seed trees,the dissemination depending almost entirely on the great part of the seed falls on the hardwood bottom whenthe land is flooded, and is either washed away or, if already LpB^P^S^BBPP™^ -»*—*?*-> -^.

After germinating, the red gumseedhng demands, above everything else, abundant hghtfor its survival and development. It is for this reasonthat there is very little growth of red gum, either m theunculled forest or on culled land, where, as is usually thecase, a dense undergrowth of cane, briers, and rattan ispresent. Under the dense underbrush of cane and briersthroughout much of the virgin forest, reproduction of anyof the merchantable species is of course impossible. Andeven where the land has been logged over, the forest isseldom open enough to allow reproduction of cottonwoodand red gum. Where, however, seed trees are contiguousto pastures or cleared land, scattered seedhngs are foundspringing up in the open, and where openings occur m theforest, there are often large numbers of red gum seed
