MONITORING OF THE FAUNA OF MANGROVE PLANTATION IN DAM BAY (TRE IS. NHA TRANG BAY)
Monitoring of fauna in mangrove plantations is extremely important for understanding developmental patterns of mangrove ecosystems, which contributes to conservation, rehabilitation and sustinable management issues of this economically and ecologically valuable system. In Dam Bay on a mud flat fringed by narrow belt of Rhizophora apiculata, seedlings of the same species were planted in 2005 and 2009. Dynamics of species richness, species composition and density of macro invertebrate fauna were recorded in newly planted mangrove association during ten years. Comparison between the fauna of mangrove plantings at Dam Bay and natural association in Nha Phu Bay was conducted. For those purposes quantitative and qualitative samples were collected from year 2005 to 2015 for Dam Bay, and years 2012 and 2014 for Nha Phu. The most diverse groups of invertebrates were gastropods, bivalves and crabs in both natural and planted mangroves. Faunal richness and quantitative characteristics altered significantly during monitoring period in newly planted mangrove association. We recorded the growth of species richness and density of eurybiotic and opportunistic species, due to the enrichment of the sediments by organic matter and appearance of new hard substrata. At the beginning of 2008, we observed progressive colonization of the plantation by specialized mangrove species, the main reasons were the growth of young plants and as a result gradual complication of vegetation structure. Nevertheless even after 10 years the plantation has lower species richness of specialized fauna than the natural association in Nha Phu. The structure of fauna i.e. proportion of specialized versus eurybiotic species and their abundance may be used as indicators of condition of mangrove associations.
