“…Even so, very many other coastal systems along the temperate Australian seaboard that are extremely important from ecological, economic and social perspectives remain very poorly known: examples include estuarine wetlands associated with the many large drowned river valleys of coastal New South Wales, including the Clarence, Manning and Hawkesbury Rivers, and the Gippsland Lakes and Corner Inlet-Nooramunga complexes in Victoria. Several syntheses of the ecology of coastal saltmarshes in Queensland, New South Wales and Victoria (Laegdsgaard 2006;Saintilan 2009;Boon et al 2011) are now available, as well as a recent review of the ecology of temperate mangroves (Morrisey et al 2010) to match the very large literature on tropical mangroves (e.g. Alongi 2009).…”

“…Responses to altered water quality and, in particular, to salinity are also poorly known for coastal plants, despite their occurrence in naturally salty environments. In an exhaustive review of temperate mangroves, Morrisey et al (2010) referred to only one work (Ball 1988) on the salinity requirements of the grey mangrove Avicennia marina, the most common mangrove in southern Australia. I expect this is because it is the only paper on the topic.…”

Coastal wetlands of temperate eastern Australia: will Cinderella ever go to the ball?

Abstract. The many sheltered embayments, riverine estuaries and drowned river valleys of temperate eastern Australia support a large area and a wide diversity of coastal wetlands. This region also supports over one-half of the country's population and includes its major tourist and industrial centres. The story of Cinderella provides an excellent simile for the status of coastal wetlands in this region of Australia: coastal wetlands provide extremely valuable ecosystem services (indeed, of considerably greater value than those provided by an equivalent area of inland wetland), yet they are undervalued by the general community, by natural-resource managers and by funding agencies. The selective investment of ecological research (including rehabilitation studies) into inland wetlands -and in particular into floodplain wetlands of the Murray-Darling Basin -has left us inadequately equipped to understand how temperate coastal wetlands function, how they will respond to climate change, and how degraded sites can be rehabilitated. Not only is an increase in research funding required, but funding has to be coordinated and focussed. The problem, however, is not only a lack of research funding; at a more fundamental level, the widespread ignorance of the value of temperate coastal wetlands needs also to be addressed.

“…australasica), covering approximately 26,050 ha (Morrisey et al, 2010;Spalding et al, 2010). The distribution range extends from the top of the North Island to approximately 38 • south (Morrisey et al, 2010). The northern area of the North Island has a warm temperate climate, with mean daily minimum temperatures of 6 • C and maximum temperatures of 25 • C throughout the course of the year.…”

Carbon and Nitrogen Stocks and Below-Ground Allometry in Temperate Mangroves

2016

View full text Add to dashboard Cite

Mangroves play an important role in the storage of carbon (C) and nitrogen (N) within estuarine systems, yet are being lost at an alarming rate throughout the tropics. In contrast, temperate mangroves have increased in area at many locations in recent decades. Field surveys, sediment sampling, allometry, and C and N analysis were used to determine total C and N stocks in five temperate Avicennia marina subsp. australasica forests in New Zealand. This is the first study developing allometric functions to estimate root biomass C and N stocks for A. marina. A. marina forests stored 117.1 ± 16.8 t C ha −1 and 15.4 ± 1.0 t N ha −1 in above and below-ground biomass and sediment to 100 cm depth. Below-ground biomass and sediment C and N stocks contributed 88 ± 3 and 99 ± 0.4% to total C and N stocks, respectively, emphasizing the importance of below-ground biomass and sediment in mangrove ecosystems. The results of this study can be used to inform management decisions for estuarine and coastal ecosystems, currently undergoing rapid changes in mangrove area.
