Under this harvest regime, beds can recover their harvested biomass within a year, [42] [43] and no long-term impact of the harvest on the biomass or morphology of A. nodosum has been observed. [44] [45] Several studies have looked at the impact of the harvest on associated species and have found only limited short-term impacts. [46] [47] [48]
