Among their key inhabitants, macrofauna play critical roles in sustaining ecosystem health and resilience through processes like bioturbation,nutrient cycling, organic matter turnover, and trophic interactions, which in turn support ecosystem servicessuch as fisheries and coastal community livelihoods. Despite their contributions, no comprehensive review hasyet focused exclusively on the diverse roles and services of salt marsh macrofauna. This review aims to addressthis gap by synthesizing current research, supported by a bibliometric analysis revealing significant growth instudies since the year 2000, especially those addressing ecosystem services and climate resilience. We provide anin-depth assessment of macrofaunal functions in bioturbation, nutrient cycling, organic matter dynamics,greenhouse gas regulation, primary and secondary production, and food web interactions. Additionally, weexamine the ecosystem services provided, such as provisioning, regulating, and cultural services, and explore theimpact of environmental stressors on macrofaunal communities. Finally, this review identifies significantknowledge gaps, offering strategic insights for future research and serving as a vital reference for advancingcoastal management and salt marsh conservation strategies.
