  1. Introduce tree/shrub seeds or propagules: brackish/saline wetlands

    A study in 1989–1993 in a historically mined mangrove in Thailand (Komiyama et al. 1996) reported that 53% of planted tall-stilt mangrove Rhizophora apiculata seedlings survived for four years, and that the average height of surviving seedlings increased over time. Statistical significance was not assessed. Seedling survival rates were 70% after one year, 55% after three years and 53% after four years. The most common seedling height was 50–75 cm after one year, then 100–125 cm after four years. The most common seedling diameter was 0.5–1.0 cm after one year, then 2.0–2.5 cm after four years. The study also suggested that survival and changes in height were affected by elevation and firmness of sediment (see original paper for data). Methods: In August 1989, tall-stilt mangrove propagules were planted into 1,000 m2 of tidal coastal land (3,950 wild-collected propagules, 50 cm apart). The area had been mined for tin in the previous decade. Data were collected immediately before planting (August 1989) and for up to four years after (November 1990, August 1992 and August 1993).
