“…Burials lead to a reduction in community diversity and native species biomass, while favoring the invasive species. In addition, seaside goldenrod, Solidago sempervirens, within invaded communities exhibited significantly lower photosynthesis rates than those individuals in non-invaded communities [79]. Their results suggest that nourishment will promote Asiatic sand sedge invasion to the detriment of native dune species.…”

“…Unfortunately, there are very few examples of this approach. One of these rare studies is an experimental research project dealing with the role of BN in the success of an invasive Asiatic sand sedge, Carex kobomugi Ohwi [79]. Dune communities were subjected to 5 burial depth treatments in ~15 cm increments ranging from 0 (control) to 60 cm burial.…”

Sand beach nourishment (BN) is one of the commonest “soft solutions” for shore protection and restoration. Yet it may have ecological consequences. Can this practice enhance the introduction and dispersal of non-indigenous species (NIS)? There has been little research on the impacts of nourishment on NIS, especially in the southeastern Mediterranean, a region considered most affected by invading biota. However, so far only one study referred to the possible interaction between BN and the success of invading species. It reports increasing numbers and densities of the aggressive, omnivorous Indo-Pacific moon crab, Matuta victor (Fabricius, 1781) in Haifa Bay (northern Israel) between 2011 and 2017. This research suggests a possible role of anthropogenic disturbance in the outbreak of M. victor and blames the Israel Ministry of Environmental Protection for authorizing a (rather small scale) BN in Haifa Bay in 2011 as an alleged cause for this outbreak. Circumstantial indirect evidence is not sufficient to establish the role of nourishment in promoting the establishment and dispersal of NIS. There are plenty of examples of successful settlement and rapid and large-scale distribution of NIS (including another member of the genus Matuta), especially in the eastern Mediterranean, without any BN in the region. Furthermore, the location where the M. victor specimens were sampled was exposed to more prevailing and frequent anthropogenic marine stressors than BN, such as eutrophication, pollution, fishing activities and particularly port construction. To firmly establish an assumed role of nourishment in the invasion of NIS, assessments must be based on solid and orderly planned scientific research to be designed well before the beginning of any BN. It is suggested that direct communication between environmental regulators and scientists is crucial for improving both scientific research and environmental management policies.

“…To predict the beach width response including alongshore variability and dunefoot migration, as observed at the Hondsbossche Dunes site, an explicit representation of the subaerial beach may be necessary. The recently developed coupled hydrodynamic and aeolian processed-based models [59,78,79] show potential to predict this behavior in the near future.…”
