Facilitate tidal exchange to restore degraded brackish/saline swamps

A before-and-after, site comparison study in southeast Mexico (Zaldívar-Jiménez et al. 2017) reported that following dredging of tidal channels to restore more natural tidal exchange to a degraded mangrove forest, mangrove seedlings colonized. Before dredging, there were no mangrove seedlings present in the study site. After dredging, there were 82 seedlings/100 m². They were 56 cm tall on average. In a nearby undisturbed mangrove, there were 3,400 seedlings/100 m². These were 40 cm tall on average. Methods: Around 2010, tidal channels were dredged in the 1,300-ha degraded mangrove forest on the edge of Términos Lagoon. This increased the flooding frequency and reduced flooding duration towards levels in undisturbed mangroves, but reduced sediment salinity below levels in undisturbed mangroves. Local communities were also engaged in restoration activities and decision-making. The study does not report details of vegetation monitoring.
