Directly plant trees/shrubs: brackish/saline wetlands
A study in a marshy, estuarine site in northeast India (Das et al. 1997) reported 25–83% survival of planted mangrove saplings after one year, and that the average size of saplings typically increased over two years. Statistical significance was not assessed. Ten species were planted. One year after planting, mangrove apple Sonneratia apetala had the highest survival rate (76–83%) and Ceriopsis decandra the lowest (25–33%). Between one and two years after planting, the average size of surviving trees typically increased: height in 20 of 20 cases, trunk diameter in 16 of 20 cases, number of branches in 15 of 20 cases and canopy diameter in 14 of 20 cases (see original paper for data). Nine of 10 species had higher survival in mixed plantations than monocultures, but size metrics were more likely to increase over time in monocultures (40 of 40 cases) than in mixed plantations (25 of 40 cases). Methods: At an unspecified time, 1-year-old mangrove saplings (reared in a nursery from cuttings) were planted 2 m apart over 10-ha degraded salt marsh within the Mahanadi Delta. Ten species were planted in single-species or mixed-species stands (further details of layout not reported). Survival was monitored after one year. Surviving saplings were measured after one and two years.
