Palustrine

Palustrine – Stocks

 

The conceptual models were compiled by researchers in collaboration with a wide range of stakeholders from Natural Resource Management groups, universities and government agencies and based on available scientific information[4].

Nitrogen stocks in palustrine wetlands are large due to organic rich soils and, in some palustrine wetlands, large trees.

Soils

Most of the nitrogen stored in palustrine wetlands (90%) is in the soil, especially the near surface layers (less than 1 m)[2][1], with nitrogen stocks up to 1,600 kg/ha. In palustrine wetlands with peat soils stocks, the peat can reach depths of over one metre and values of N can be >13,000 kg/ha[1].

Vegetation

In forested palustrine wetlands, the trees can store > 119 kg/ha, with some forests of Melaleuca quinqueflora and Melaleuca quinquenervia storing up to 900 kg/ha[1].

Biota

Palustrine wetlands often contain temporary populations of crocodiles (in north Queensland), turtles, fish, birds, reptiles, and bats, which store nitrogen in their tissues.
