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

    A replicated study in 2008 in two coastal sites in the Cayman Islands (Krumholz & Jadot 2009) reported 48–84% survival of planted red mangrove Rhizophora mangle saplings after 10 months, and that the average height of surviving trees increased. After five months, 94% of the planted saplings were still alive in both sites. After 10 months (including hurricane season), survival rates had dropped to 84% in the sheltered site and 48% in the exposed site. The average height of surviving seedlings was similar in both sites: 39 cm when planted, 42 cm after five months, and 51–52 cm after 10 months (statistical significance not assessed). Methods: In early 2008, approximately 400 containers of 2–3 red mangrove saplings were transplanted into shallow water across two coastal sites. The containers were specially designed concrete pots: 25 cm tall, 40–45 cm diameter, 16 kg when empty, holes in the sides to allow water exchange and the bottom to allow root growth. Saplings had been grown in the containers in a nursery for 15 months. Sapling survival and height (tallest sapling in each container) were monitored in January, June and December 2008.
