Implementation of coral restoration practices within reef management strategies is accelerating globally to support resilience and recovery. However, full costs underpinning project feasibility have historically been underreported yet are critical informing cost-benefit decision-making. Such knowledge especially lacking for Australia’s Great Barrier Reef (GBR), where a program led by tourism operators, Coral Nurture Program (CNP), was initiated in 2018 (northern GBR) continues scale. Here we describe the early outcomes implementing similar tourism-led asexual propagation outplanting new region, Whitsundays (central through CNP. Specifically, detail local operational environmental context CNP Whitsundays, implementation continuation activities, as well evaluate survivorship outplants across three sites nine months after establishment (August 2022 June 2023). Baseline benthic surveys revealed relatively low hard cover at (ranging from 3.22-8.67%), which significantly differed composition collection 16.67-38.06%), supporting strong motivation operators undertake activities. Mean fate-tracked plots between 267 days 23.33-47.58%), with declines largely driven detachment. Early-stage cost-effectiveness (costs relative outplant survival) associated activity varied widely US$33.04-178.55 per surviving (n = 4,425 outplants) depending on whether ‘in-kind’ costs, (outplanting only vs. total encompassing planning monitoring), site-based survivorship, or combination these factors, were considered. As projects continue be established globally, our results highlight need ongoing, long-term monitoring that can inform adaptive practice, fully transparent cost-reporting understand improve any given project. We further inherent context-dependency importance considering social-environmental contexts their cost-benefits economic rationale projects.

Artificial reefs for coral reef restoration are often concrete-based. After concrete is poured, it initially has a high surface pH (approx. 13), which neutralizes within several weeks. During this curing, colonization by marine microalgae delayed and also macrobenthos such as corals may be impacted. In study, we evaluated how curing time applied prior to the deployment of artificial affected performance. Fragments five species were outplanted onto ordinary Portland discs ( n = 10) that had been cured on land. Seven different periods applied, ranging from one day up four months. The with deployed at Kenyan photographed start end experiment. 1 year, cover increased declined one, but was unrelated time. Also, no effect seen development other common benthic organisms macroalgae or soft corals. We conclude unlikely have any long-term negative impacts performance therefore, extended attachment benefit efforts.

Restoration and artificial reefs can assist the recovery of degraded but are limited in scalability climate resilience. The Mineral Accretion Technique (MAT) subjects metal to a low-voltage electrical current, thereby creating calcium-carbonate coating. It has been suggested that corals on MAT structures experience enhanced health growth. However, prior studies report conflicting results potentially due different conditions, species approaches used. We investigated how influences bleaching resilience, condition growth four coral natural recruitment Kenya. Coral fragments were outplanted charged iron tables using commonly-applied settings (6 V; 0.84 A m -2 ). After one month, when all had acquired coating, half taken off electricity serve as controls.
