Directly plant trees/shrubs: brackish/saline wetlands
A study in 2000–2001 in a lagoon in southern Mexico (Reyes Chargoy & Tovilla Hernández 2002) reported 95% survival of planted red mangrove Rhizophora mangle seedlings after seven months, and that the average height of surviving seedlings increased. Statistical significance was not assessed. When planted, seedlings were 32 cm tall on average. Seven months later, surviving seedlings were 72 cm tall on average. Methods: In late 2000, a total of 550 nursery-reared red mangrove seedlings (90 days old) were planted at the edge of Pozuelos lagoon (elevation not reported). This site was flooded by two tides/day throughout the year. Surviving seedlings were surveyed for up to seven months after planting.

Introduce tree/shrub seeds or propagules: brackish/saline wetlands
A replicated study in 2000–2001 in two lagoons in southern Mexico (Reyes Chargoy & Tovilla Hernández 2002) reported 39–100% survival of planted red mangrove Rhizophora mangle propagules after 8–11 months, but that the average height of surviving seedlings increased. Statistical significance was not assessed. Pozuelos Lagoon was flooded by two tides/day throughout the year. Here, all 3,019 planted propagules apparently produced surviving seedlings eight months later. These were 65 cm tall on average (vs 11 cm one month after planting). However, the study also reported extensive natural colonization by mangrove seedlings (> the number of propagules planted), and it is unclear if/how planted and unplanted seedlings were distinguished. In Cabildo Lagoon, only 39% of 19,345 planted propagules produced surviving seedlings after 8–11 months. These were 60–75 cm tall on average (vs 12–18 cm one month after planting). The study suggests that seedlings in this site were killed by low water levels and trampling by people and animals. Methods: Between June and September 2000, field-collected red mangrove propagules were planted in the intertidal zone of two lagoons (from 20-cm-deep water to the “limit of the wet zone”). Surviving seedlings were surveyed for up to eleven months after planting.
