  1. Directly plant trees/shrubs: brackish/saline wetlands

    A 1977 review of mangrove plantings in Florida, USA (Teas 1977) reported 0–100% survival of planted seedlings or trees over six months to 32 years. Experiments yielding high survival rates included: planting seedlings in sheltered coastal sites (85–90% survival after 1–4 years); planting >4-year-old trees, with roots wrapped in burlap, at or above mid-tide level (80–100% survival after 13 months); and planting trees, each 0.3–3.6 m tall, alongside sheltered canals (100% survival after six months). Experiments yielding low survival rates included: planting seedlings in exposed east-coast sites (0–2% survival after 7–10 months); planting >4-year-old trees below mid-tide level (0% survival after 13 months; insect damage noted); transplanting fourteen trees, each 4.6–6.1 m tall (0% survival after six months); and planting young seedlings in the Dry Tortugas Islands (80% survival after one year but 0% survival after 32 years). Methods: The review reported results from several experiments planting mangrove seedlings or trees under a range of conditions. Most experiments involved planting red mangrove Rhizophora mangle; some also included black mangrove Avicennia germinans and white mangrove Laguncularia racemosa. Between 14 and 60,000 plants were planted in each experiment. Some were nursery-reared and some were transplanted from wild populations.
