Reprofile/relandscape: brackish/saline swamps
A site comparison study in the early 1990s on the coast of Singapore (Lee et al. 1996) reported that an area reprofiled to the same elevation as a neighbouring remnant mangrove forest was colonized by mangrove vegetation within 42 months, but with greater plant species richness and fewer, shorter plants than the remnant mangrove. Statistical significance was not assessed. After 42 months, the reprofiled area contained 9 plant species and 241 individual plants along an 80-m2 transect (vs natural: 7 species and 487 individuals). Most plants in the reprofiled area were ≤2 m tall (75%) and the tallest were ≤6 m. In the remnant mangrove, most plants were also <2 m tall (77%) but some were >8 m. The reprofiled area was dominated numerically by smallflower bruguiera Bruguiera parviflora (50% of individuals, but mostly saplings) whereas the remnant mangrove was dominated numerically by Avicennia alba (67% of individuals, but mostly saplings). Methods: In 1988, a 1-ha plot between a remnant patch of mangrove forest and a tidal river was reprofiled to allow tidal inundation around 40–50 times/month (as in the remnant mangrove). Forty-two months later, vegetation was surveyed along a 2 x 40 m transect in the reprofiled plot and the remnant mangrove. All individual plants were identified and measured.
