Use structures made from unnatural materials to restore / repair / create habitat for corals to encourage natural coral settlement
A replicated, randomized, controlled study in 2005–2007 at three degraded coral reefs in northern Sulawesi, Indonesia (Ferse et al. 2013) found that concrete structures placed close to transplanted stony coral fragments had similar numbers of stony coral recruits to structures placed further away. The number of coral recruits was similar on concrete structures placed next to transplanted corals compared to structures placed away from corals in eight of nine comparisons (next to transplants: 0.02–0.28 corals/100cm2, away from transplants: 0.03–0.26 corals/100cm2), and higher in the ninth comparison (next to transplants: 0.58 corals/100cm2, away from transplants: 0.36 corals/100cm2). For limestone plates placed next to, or distant from, transplanted corals there were a similar number of recruits in 15 of 18 comparisons, more recruits in two comparisons, and fewer in one comparison (see paper for data). In July 2005–March 2006, six-thousand-one-hundred-and-sixty-four stony coral fragments (Acropora yongei, Pocillopora verrucosa, Acropora muricata, Isopora brueggemanni) were collected from donor colonies near three transplant sites. Two plots (10 × 10 m) at each of three sites, with each plot randomly assigned to either: concrete structures (25/plot) alternating in a ‘chessboard’ design with transplanted stony coral fragments attached to bamboo frames; or concrete structures only (25/plot). At all plots, six groups of three limestone settlement plates were also installed on metal frames. Coral recruits that settled on concrete structures were counted after 14–24 months. Recruits on limestone plates were counted every three months for 14–24 months. Plates were replaced every three months.
