Coastal restoration is often distrusted and, at best, implemented small scales, which hampers its potential for coastal adaptation. Present technical, economic and management barriers stem from sectoral poorly coordinated local interventions, are insufficiently monitored maintained, precluding the upscaling required to build up confidence in ecosystem restoration. The paper posits that there enough knowledge, technology, financial governance capabilities increasing pace scale of restoration, before onset irreversible degradation. We propose a systemic integrates Nature based Solutions (NbS) building blocks, provide climate-resilient services improved biodiversity curb result should be reduction risks decarbonised protection, same time increases blue carbon. discuss enablers adaptation-through-restoration plans, on vulnerable archetypes, such as deltas, estuaries, lagoons bays.

Restoring mangrove biodiversity: can restored mangroves support fish assemblages comparable to natural mangroves over time?

Restoration Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 21, 2025

Despite the recent global increase in mangrove restoration efforts, our understanding of outcomes and recovery biodiversity re‐establishing functionality, such as productive fish habitat, is limited due to lack long‐term monitoring. Here, we used a space‐for‐time approach investigate whether restored mangroves attain similar communities natural same age (5–11 years old). Fish forests along Guyana coastline, South America, were sampled using trammel nets collect data compare abundance, species richness, biomass. This study found no notable differences assemblages between ages. Nonmetric multidimensional scaling (NMDS), analysis similarities (ANOSIM), similarity percentage (SIMPER) revealed high overlap composition habitats, age, seasons, diel cycle. There was clear trajectory biomass, which indciates that quickly colonized habitats. Our provides evidence success projects yielding positive ecological benefits habitat. information useful for practitioners when setting goals timelines habitat after restoration.

Abstract Mangroves, tidal marshes and seagrasses have experienced extensive historical reduction in extent due to direct indirect effects of anthropogenic land use change. Habitat loss has contributed carbon emissions led foregone opportunities for sequestration, which are disproportionately large high ‘blue carbon’ stocks sequestration rates these coastal ecosystems. As such, there been a rapid increase interest using habitat restoration as climate change mitigation tool. This review shows that efforts able substantially blue stocks, while also having positive impact on various gaseous fluxes. However, increases spatially variable, biophysical factors such geomorphic setting. While potentially hundreds thousands hectares may be biophysically suitable restoration, activities still often conducted at small scales with mixed success. Maximizing potential gains through will require managers planners overcome the myriad socioeconomic governance constraints related tenure, legislation, target setting cost, push projects into locations unsuitable plant colonization.

As efforts to restore coastal habitats accelerate, it is critical that investments are targeted most effectively mitigate and reverse habitat loss its impacts on biodiversity. One likely but largely overlooked impediment effective restoration of habitat-forming organisms failing explicitly consider non-habitat-forming animals in planning, implementation, monitoring. These can greatly enhance or degrade ecosystem function, persistence, resilience. Bivalves, for instance, reduce sulfide stress seagrass increase drought tolerance saltmarsh vegetation, whereas megaherbivores detrimentally overgraze improve seed germination, depending the context. Therefore, understanding when, why, how directly manipulate support outcomes. In this expanded approach, we provide a conceptual framework, incorporating lessons from structured decision-making, describe potential actions could lead better outcomes using case studies illustrate practical approaches.

Mangrove forests, benefitting millions of people, experience significant degradation. Global recognition the urgency halting and reversing this trend have initiated numerous restoration activities. Restoration success is typically evaluated by estimating mangrove survival area restored, while diversity structure vegetation, as proxies for functional are rarely considered. Here we assess species richness along sea‐landward transects evaluate outcomes comparing number species, relative abundance, biomass, diameter, canopy cover in “Monoculture Reforestation”, “Mixed Species Regeneration” adjacent “Reference” forest stands, 14 (Tiwoho site) 16 years (Likupang after activities took place. In Reforestation” plots, still closely reflected original actions, with only one two “new” having established among originally densely planted “foundation” species. contrast, plots were more similar to terms tree diameter coverage, but number, abundance biomass lower. The trajectory suggests their similarity stands will increase over time, whereas such “smooth” transition unlikely happen foreseeable future. Implementing frequent small‐scale disturbances restored management would stand diversity, accelerating establishment a natural, likely resilient forest.
