“…Condition was used to give less importance to wetland sites with degraded ecological integrity, thus generally avoiding highly invaded sites unless they were irreplaceable. Lagabrielle et al (2009) designed conservation corridors through a least-cost path analysis by optimizing both ecological and socio-economic constraints expressed in a cost matrix. Invasive plants were included in this cost matrix through a threats score that combined urbanization, agriculture and plant invasion.…”

“…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.

a b s t r a c tThe present study deals with the development of systematic conservation planning as management instrument in small oceanic islands, ensuring open systems of governance, and able to integrate an informed and involved participation of the stakeholders. Marxan software was used to define management areas according a set of alternative land use scenarios considering different conservation and management paradigms. Modeled conservation zones were interpreted and compared with the existing protected areas allowing more fused information for future trade-outs and stakeholder's involvement. The results, allowing the identification of Target Management Units (TMU) based on the consideration of different development scenarios proved to be consistent with a feasible development of evaluation approaches able to support sound governance systems. Moreover, the detailed geographic identification of TMU seems to be able to support participated policies towards a more sustainable management of the entire island.
