Background information and definitions
Many populations of marine subtidal benthic invertebrate species have declined or been depleted due to the multiple threats they are under, including habitat damage or loss and direct physical damages from anthropogenic activities (Airoldi et al. 2008; Hobday et al. 2000). As a pre-emptive conservation measure, species can be temporarily removed to allow for an impactful activity to occur, then relocated back into their original location, or at a different location. Such measure has been trialled to preserve maërl (rhodolith) species and the habitat it forms during the dredging of new shipping channels (Sheehan et al. 2015; see “Habitat restoration and creation – Remove and relocate habitat-forming (biogenic) invertebrate species before onset of impactful activities”).
