Date-commence: | August 1994 |
Duration: | 2 years |
Locations: | An urban wetland at Tainan City, Taiwan |
Sponsors: | Council of Agriculture, Executive Yuan |
Collabs: | - |
Objectives: | Restore the mangrove ecosystem that was destroyed for aquaculture in 1974. |
| The site is only 1.5 ha, Rhizophora stylosa, Avicennia marina and Kandelia candel were directly sowed The site is only 1.5 ha, Rhizophora stylosa, Avicennia marina and Kandelia candel were directly sowed with propagules, and Lumnitzera racemosa were planted with one-year-old seedlings. The survival rate and growth of all four mangrove species progressed very well during the first two years of the project. However, growth was arrested by stresses from the harsh environment, including high salinity, heavy low-nutrient soil (fish farmers removed the fertile silt), strong winds and heavy salt spray during the winter. The author visited the site in August 2001, when only 15 R. stylosa saplings had with propagules, and Lumnitzera racemosa were planted with one-year-old seedlings. The survival rate and growth of all four mangrove species progressed very well during the first two years of the project. However, growth was arrested by stresses from the harsh environment, including high salinity, heavy low-nutrient soil (fish farmers removed the fertile silt), strong winds and heavy salt spray during the winter. The author visited the site in August 2001, when only 15 R. stylosa saplings had survived, and the K. candel samples also gradually declined and died. The salt tolerant A. marina is the dominant species but a dwarf mangrove form (seven years old) is present, with a sapling height of only 35-70 cm. Most of the L. racemosa seedlings survived, but these have not grown significantly in height either. |
| Keep observing the growth performance of A. marina and L. racemosa. It is no need to replant any mangrove species in future. |
