Cordgrass Introduced for Land Reclamation Spreads as Invasive Species in New Zealand and China
In the mid-20th century, New Zealand and China introduced cordgrass species to reclaim tidal wetlands for grazing and land development. In New Zealand, cordgrass planted since the 1940s spread aggressively, altering estuaries and affecting local ecosystems. Similarly, China introduced smooth cordgrass in 1979, which now covers about 68,000 hectares along its coast, reducing feeding and resting habitats for shorebirds. Both countries now recognize cordgrass as an invasive species with significant ecological impacts on coastal mudflats.
