Coastal marine ecosystems provide critical goods and services to humanity but many are experiencing rapid degradation. The need for effective restoration tools capable of promoting recovery coastal remediating their valued has never been greater. We identify four major challenges the future development implementation ecosystem (MER): (1) Development more effective, scalable tools, (2) adaptation cope with climate change global stressors, (3) integration social ecological priorities, (4) promotion perception use MER as a scientifically-credible management approach. Tackling these should improve success rates, heighten recognition, accelerate investment in MER. Here, reverse currently accelerating decline ecosystems, we discuss potential directions meeting by applying that science-based actionable. For have impact, it must incorporate science, technological conceptual advances, plan climates.

In 2019, the United Nations Environment Assembly requested that Programme (UNEP) and International Coral Reef Initiative (ICRI) define best practices for coral restoration. Guidelines led by UNEP were prepared a team of 20 experts in reef management, science, policy to catalog best-available knowledge field provide realistic recommendations use restoration as management strategy. Here, we synthesis these guidelines. Specifically, present (1) case value face increasing frequency intensity disturbances associated with climate change, (2) set improving strategy, tailored goals current methods. can be useful tool support resilience, especially at local scales where recruitment is limited, mitigated.

Abstract Coral reefs worldwide are increasingly damaged by anthropogenic stressors, necessitating novel approaches for their management. Maintaining healthy fish communities counteracts reef degradation, but degraded smell and sound less attractive to settlement-stage fishes than states. Here, using a six-week field experiment, we demonstrate that playback of can increase settlement retention habitat. We compare community development on acoustically enriched coral-rubble patch with unmanipulated controls. Acoustic enrichment enhances across all major trophic guilds, doubling in overall abundance 50% greater species richness. If combined active habitat restoration effective conservation measures, rebuilding this manner might accelerate ecosystem recovery at multiple spatial temporal scales. shows promise as tool the management coral reefs.
