Cover Story: Following the fast and continuous degradation of coral reefs worldwide, new approaches for coral reef restoration and adaptation were raised, some are being tested. This manuscript describes 7 novel approaches that are further classified into three operation levels (improved methodologies/ecological engineering; “assisted” approaches; epigenetics/chimerism). While the literature discusses each approach separately, this concept paper unifies all under the single umbrella of the ‘coral gardening’ tenet, also revealing that each level is based on the accomplishment of the other levels. This is the first attempt to combine all reef restoration tactics under a single working rationale. Legend to the figure: Farmed Acropora coral colonies in the mid-water floating nursery at Eilat (Israel), the Red Sea. Each colony has started from a coral nubbin in the size of few mm length (Courtesy: S. Shafir). View this paper.
