Introduce fragments of non-woody plants: freshwater wetlands
A replicated study in 2010–2012 in a tidal freshwater marsh in California, USA (Sloey et al. 2015) reported that all planted sedge and reed rhizomes died for two of three species, but that they survived and spread for the other species. Three months after planting, all rhizomes of hardstem bulrush Schoenoplectus acutus and broadleaf cattail Typha latifolia had died (i.e. none had produced shoots). In contrast, California bulrush Schoenoplectus californicus rhizomes were alive in all four areas where they were planted, with 6–31% of individual rhizomes having produced shoots. After 24 months, California bulrush was still present in all four areas and had spread to cover 4–23 m2/site. Methods: In June 2010, one hundred and ninety two rhizomes were planted into four areas within the marsh (16 rhizomes/species/area). Survival was quantified in September 2010. Cover was measured until June 2012. The study areas were flooded for 82–99% of each summer.

Directly plant non-woody plants: freshwater wetlands
A replicated study in 2010–2012 in a tidal freshwater marsh in California, USA (Sloey et al. 2015) reported that planted sedges and reeds survived for three months in 10 of 12 cases, but were present after two years in only 2 of 12 cases. Three species were planted in each of four areas. After three months, all four areas contained planted California bulrush Schoenoplectus californicus (44–94% of individual plants alive) and hardstem bulrush Schoenoplectus acutus (25–75% of individual plants alive). However, only two of four areas contained planted broadleaf cattail Typha latifolia (where 25–56% of individual plants were alive). After 24 months, the bulrush species were each present in only one of four areas (area covered: 0.1–2.4 m2) and broadleaf cattail was not present in any area. For all species, initial survival was statistically similar in open water areas (0–94%) and on the marsh fringe (0–75%). Methods: In June 2010, one hundred and ninety two nursery-grown plants were planted into four areas within the marsh (16 plants/species/area). Survival was quantified in September 2010. Cover was measured until June 2012. The study areas were flooded for 82–99% of each summer.
