Palustrine Wetland

Definition - What does Palustrine Wetland mean?

A palustrine wetland is defined as a non-tidal wetland with ocean derived salinity of less than 0.5%. The word palustrine is derived from palus which means marsh in Latin. These wetlands are dominated by mosses, lichens, shrubs, and trees, but there are also wetlands that do not have any vegetation. Trenchless construction allows for the laying of pipeline in such areas without disturbing the delicate balance of nature that exists.

These wetlands are also known as marsh, bog, and swamp.

Trenchlesspedia explains Palustrine Wetland

Palustrine wetlands are distinguished by the following characteristics. 1- Spread in an area of 20 acres or less; 2- No tidal waves, shore line or wave formations; 3- Salinity less than 0.5%; 4- Maximum depth of 2 m at deepest part in low water. Palustrine wetlands are abundant throughout the United States. While laying pipeline, it is not uncommon to encounter one of these sites on the project route. To minimize impact on these wetlands, trenchless technology uses boring, horizontal drilling, and micro-tunneling to cross under such areas. Palustrine wetlands are able to regenerate very quickly, usually within one growing season, hence, any disturbance to a limited area is easily restored. Using trenchless methods prevents any damaging disturbance to natural habitats.
