Mangrove – 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[5].

Soils

Stocks of nitrogen (N) in mangrove forest soils in tropical Australia are higher beneath Avicennia marina (11,653 kg/ha) compared to Rhizophora stylosa (10,330 kg/ha)[1]. The N content of mangroves in regions of the Great Barrier Reef catchments is 10,992 (8,655-11,653) kg/ha*[3]. Soil accounts for more than 90% stock of N within a mangrove forest[2].

Vegetation

The N stock in mangroves in the Great Barrier Reef region averages 472 (412-532) kg/ha*[1]. Higher N stocks have been measured in Rhizophora stylosa trees (532 kg/ha) compared to Avicennia marina trees (412 kg/ha)[2].

*Nitrogen quantities are displayed as an average followed by a minimum and maximum (range), e.g. “average (min. of range - max. of range) units”.
