Introduce tree/shrub seeds or propagules: brackish/saline wetlands
A replicated, before-and-after study in 2012–2013 in a brackish/saline estuarine site with mudflats and existing mangroves in southeast China (Peng et al. 2016) reported 38–100% germination of planted mangrove propagules. Germination rates depended on the combination of species and the habitat in which it was planted. For example, the germination rate of non-native mangrove apple Sonneratia alba ranged from 67% amongst the oldest, darkest forest to 100% on bare mudflats. Three native mangrove species had germination rates of 38–90%, but only one (river mangrove Aegiceras corniculatum) was clearly affected by the habitat. Methods: In June 2012, propagules of four mangrove tree species were planted into four habitats: a tidal mudflat, a 2-year-old mangrove apple plantation, a 4-year-old mangrove apple plantation, and an 8-year-old mangrove apple plantation. Twelve sets of 30 propagules were sown for each species (3 sets/species/habitat). Germination was monitored daily for 20 days.

Directly plant trees/shrubs: brackish/saline wetlands
A replicated, before-and-after study in 2012–2013 in a brackish/saline estuarine site with mudflats and existing mangroves in southeast China (Peng et al. 2016) reported 0–80% survival of planted seedlings over 12 months, and that surviving seedlings grew. The lowest survival rate (0%) was exhibited by three of four species, including non-native mangrove apple Sonneratia apetala, in a strongly shaded, 8-year-old mangrove plantation. The highest survival rate (74%) was for river mangrove Aegiceras corniculatum in a lightly shaded, 2-year-old mangrove plantation. The study reported increases in the biomass, height and basal area of surviving seedlings (statistical significance not assessed). Growth rates depended on the combination of species and the habitat in which it was planted (see original paper). Methods: In June 2012, seedlings of four mangrove tree species were planted into four habitats: a tidal mudflat, and 2-, 4- and 8-year-old mangrove plantations. Twelve sets of 50 seedlings were sown for each species (3 sets/habitat). Seedlings were monitored every three months for a year.
