Consequently, the derivation of riparian woodlands is entirely different from that of the rest of our flora. The closest relatives to riparian species come from summer-wet climates such as those across the Midwest and eastern parts of the United states. Wander in these forests if you are homesick for the look and feel of eastern hardwood forests. Nearly all are deciduous in winter, for they can afford to make whole new sets of leaves the following year, come what may. They are also borne in thick tiers from top to bottom.
Riparian trees reach maturity quickly because they're able to grow over such long periods each year.
Quick growth may cause weak wood, however, and many riparian trees are liabilities because of brittle limbs. They also have relatively short life spans.
