Natural recolonization of seagrasses may take decades after disturbances and is particularly challenging in near‐shore environments, where sediment mobility inhibits seagrass establishment. We assisted fifteen 4x10 m unvegetated experimental plots a Mexican Caribbean fringe the had died due to massive inundations holopelagic Sargassum species, containment barrier was placed avoid future inundations. The applied treatments were: artificial substrate (AS: 90 belowground, artificial, biodegradable, 15x15 cm‐sized substrates, cut from 0.91 x 0.45m Biodegradable EcoSystem Engineering sheet), transplant (TR: cores, 4.5 cm diameter, with Halodule wrightii ), control (C: no manipulation), each five replicates. After 6 months, 63% H. transplants survived, presenting mean rhizome extension 7.6 cm, natural surrounding patches started colonize plots. approximately 8 AS TR already showed higher light conditions lower fluctuations levels than controls. 14 reached (± SE) density (respectively, 4024 ± 620 3484 360 shoots/m 2 ) cover (60.3 3.85 53.7 2.84 %), compared (2043 381 , 35.3 5.7 % cover). Higher likely favored establishment Thalassia testudinum seedlings, an average 2.07 0.15) 1.87 0.18) seedlings plots, respectively, 0.48 0.23) Both techniques accelerated recolonization, but substrates required less effort avoided harvesting donor meadows.
