| 説明 | This primeval scene is beside the Natchez Trace Parkway at mile 122, east of Canton, Mississippi. The National Park Service has provided a nice boardwalk to help the visitor experience this silent and gloomy place. In the lower right a few cypress knees can be seen protruding upward out of the water. A cypress knee is a distinctive structure forming above the roots of a cypress tree of any of various species of the subfamily Taxodioideae. Their function is unknown, but they are generally seen on trees growing in swamps. Some current hypotheses state that they might help to aerate the tree's roots, create a barrier to catch sediment and reduce erosion, assist in anchoring the tree in the soft and muddy soil, or any combination thereof. (Source: Wikipedia)Many years ago, the Pearl River flowed here but then changed course. A shallow area was created by the deposition of sediments as the river retreated. During periodic low water, seedlings of water-tolerant cypress and tupelo trees gained a foothold. The trees you see today are a result. Water tupelo and bald cypress trees can live in deep water for long periods. After taking root in the summer when the swamp is nearly dry, the seedlings can stay alive in water deep enough to kill other plants.
