Species Info

  • Rhizophora apiculata

Description

  • A common cause of failure of mangrove reforestation is from the changes in sediment properties that occurred when the vegetation was removed from the sediment.
  • In the Saigon River Delta in Southern Vietnam, large amounts of herbicides were sprayed during the Second Indochina war, which lead to the destruction of dense mangrove vegetation.
  • After the war, reforestation, using Rhizophora apiculata seeds and saplings, took place between 1978 and 1986.
  • This research evaluates the spatial gradients of redox potential (Eh) and pH as well as the sediment aluminum, iron, phosphorous, calcium, and nitrogen in transects along the planted stands.
  • The authors found that pH (acidity) had a strongly negative affect on the sediment nutrients and leaf P and N in the reforestation plot (except for sediment N which increased with acidity).
  • The increase in iron and aluminum with acidity appeared not to affect mangrove growth.
