Saltmarsh Habitat Continues to Support Thriving Fish Populations

Fish populations are flourishing for a second consecutive year within a saltmarsh established to counteract industrial impacts. The Environment Agency (EA) conducted surveys at the Greatham, Teesside site, which was created to restore habitats, thereby enabling the return of migratory fish species that had been absent for centuries. According to the EA, the species diversity observed in this year’s survey remained consistent with the previous year’s findings, which had marked the highest diversity recorded since monitoring commenced. Among the species identified were flounders, herring, thin-lipped grey mullet, and more than 1,000 healthy crabs. The EA states that the Tees estuary is recognized as one of the most industrialized estuaries within the United Kingdom. This saltmarsh was finalized six years prior as an element of both the Greatham North managed realignment scheme and the Port Clarence and Greatham South Flood Alleviation Scheme. Its objective was to reinstate habitats that had been eradicated during the construction of flood defences. The ongoing monitoring efforts, initiated in 2021, are integrated into Tees Tidelands, a £30 million initiative designed to realign flood defences and restore mudflat and saltmarsh habitats. Anthony Crook, an environment monitoring officer for the EA, commented that the findings provided a “great indication” that the work undertaken by Tees Tidelands would “make a difference for generations to come.” He further stated, “There’s still a lot of investigation to do as these sites continue to develop and evolve.”
