“…A total introduced fish score was used to down-weigh condition index, which together with irreplaceability feeds the ranking algorithm defensible conservation zones in freshwater systems with greater potential to remain free of a highly invasive diatom. Another strategy was followed by Sealey et al (2014), who estimated cumulative impact scores in coastal ecosystems due to physical restructuring, destructive uses, coastal development, and alien plant invasions, evaluating high-score areas as non-priority for conservation actions. One approach followed by some studies was to integrate alien species in the cost function of MARXAN (Hermoso et al, 2011(Hermoso et al, , 2013Lawrence et al, 2011) or ZONATION (Stewart et al, 2017), which was aimed to be minimized in the prioritization process.…”

“…Specifically in the marine environment, the approaches that have been followed so far were to either protect alien biodiversity by setting conservation targets in MARXAN for both native and alien species (Giakoumi et al, 2011), or by estimating cumulative impact indices that included invasive alien species and either incorporate them in the cost function (Tallis et al, 2008), or adequately modify the optimization algorithm of MARXAN (Klein et al, 2013). All the other approaches applied in the freshwater or terrestrial environments can be transferred to the marine environment as well, i.e., exclusion of highly impacted areas Rouget et al, 2003;Pierce et al, 2005;Olson et al, 2010;Reid et al, 2012;Sealey et al, 2014), maximizing contribution to measures of condition and complementarity (Ausseil et al, 2011), or applying a least-cost path analysis including invasive alien species in the cost matrix (Lagabrielle et al, 2009). …”

Biological Invasions in Conservation Planning: A Global Systematic Review

et al. 2018

Biological invasions threaten biodiversity in terrestrial, freshwater and marine ecosystems, requiring substantial conservation and management efforts. To examine how the conservation planning literature addresses biological invasions and if planning in the marine environment could benefit from experiences in the freshwater and terrestrial systems, we conducted a global systematic review. Out of 1,149 scientific articles mentioning both "conservation planning" and "alien" or any of its alternative terms, 70 articles met our selection criteria. Most of the studies were related to the terrestrial environment, while only 10% focused on the marine environment. The main conservation targets were species (mostly vertebrates) rather than habitats or ecosystems. Apart from being mentioned, alien species were considered of concern for conservation in only 46% of the cases, while mitigation measures were proposed in only 13% of the cases. The vast majority of the studies (73%) ignored alien species in conservation planning even if their negative impacts were recognized. In 20% of the studies, highly invaded areas were avoided in the planning, while in 6% of the cases such areas were prioritized for conservation. In the latter case, two opposing approaches led to the selection of invaded areas: either alien and native biodiversity were treated equally in setting conservation targets, i.e., alien species were also considered as ecological Mačić et al. Biological Invasions in Conservation Planning features requiring protection, or more commonly invaded sites were prioritized for the implementation of management actions to control or eradicate invasive alien species. When the "avoid" approach was followed, in most of the cases highly impacted areas were either excluded or invasive alien species were included in the estimation of a cost function to be minimized. Most of the studies that followed a "protect" or "avoid" approach dealt with terrestrial or freshwater features but in most cases the followed approach could be transferred to the marine environment. Gaps and needs for further research are discussed and we propose an 11-step framework to account for biological invasions into the systematic conservation planning design.

“…However, such a relationship was not found in other zones. Coastal plants can be critical indicators of the ability for a locality to recover from vegetation removal or coastal alterations and they can improve coastal condition over time, but native plant revegetation alone cannot restore or rehabilitate severely impacted coastlines (Sealey et al 2014). A well-developed and diverse dune plant community acts as an ecosystem engineer that provides unique ecosystem function, including buffering intertidal habitats and protecting sensitive inland ecosystems from the negative effects of erosion.…”

“…Physical alterations happening to the shoreline will impact coastal processes such as waves, changes in sea level, and sediment supply, and caused to the loss of biological diversity, erosion of beaches and loss of coastal dune habitats and all of these changes can impact ecosystem function, particularly shoreline stabilization (Sealey et al 2014). Erosion and shoreline retreat often result in man-made coastal defense structures that cover part of the intertidal and upper-shore zones causing coastal squeeze and habitat loss for coastal dune plants.…”

Coastal erosion resulted in dramatic changes in the structure of coastal dune communities for example many characteristic species may be removed from dune zones. The effects of coastal erosion on coastal dune communities in north of Turkey were investigated along seashore-inland gradient. It has been found that the severity of erosion caused to increase the differences among coastal dune communities. Our results also implied that embryonic shifting dunes represented by Achilleo maritimo-Elymetum farcti (EU Habitat 2110) and shifting dunes along the shoreline with Ammophila arenaria (white dunes) represented by Medicagini marinae-Ammophiletum arundinacea (EU Habitat 2120) were more prone to coastal dynamics. It has been found that the severity of erosion caused to increase the differences among coastal dune communities.

“…Previous studies have reported the diverse impacts on island land expansion, which is subject to various types of interference, such as reclamation (Lou, Liu, and Zhu, 2012;Xu and Yu, 2003), urbanization (Crawford, Marcucci, and Bennett, 2013;Tzanopoulos, Mitchley, and Pantis, 2005), tourism (Sealey, McDonough, and Lunz, 2014;Tzanopoulos and Vogiatzakis, 2011;Wang and Liu, 2013;Wong, 1998), agricultural activities Koulouri, 2006, 2010;Shoyama and Braimoh, 2011), and governmental policy (Lagabrielle et al, 2011;Lloyd and Shucksmith, 1985). However, these factors have been commonly treated separately using single-case studies.…”
