Final plan of management for the Lancelin Island lagoon fish habitat protection area.

The Lancelin Island Lagoon is a small area of reef habitat on the western side of Lancelin Island and a popular snorkelling and diving destination. Water depth ranges from less than 0.3 m on the intertidal reefs to less than 3 m on the sand or seagrass-covered bottom. The area has a diverse array of benthic marine habitat. During a marine survey of the area, over 200 flora and fauna species were positively identified, with many more remaining unidentified due to the diversity of species supported in this marine environment. The survey, which was facilitated by direct observations and photographs, also identified 13 large corals that are a feature of the lagoon\u27s environment. Lancelin Island Lagoon is accessible to divers and swimmers only during low swell, as a strong current develops from wave energy converging over the outside reefs. The peak use period of the lagoon coincides with low summer/autumn swells, making it a popular destination for holidaymakers. The deeper areas of the lagoon are currently accessible by boat, but a conflict of use exists between boats, divers and swimmers, due to the lagoon\u27s small area. Extensive fishing and spearfishing has resulted in the local extinction of many larger edible species, with smaller fish now being targeted. The purpose of the Lancelin Island lagoon FHPA is to be established are: i) the conservation and protection of fish, fish breeding areas, fish fossils or the aquatic ecosystem; ii) the management of fish and activities relating to the appreciation or observation of fish

Recent advances of quantitative modeling to support invasive species eradication on islands

The eradication of invasive species from islands is an important part of managing these ecologically unique and at-risk regions. Island eradications are complex projects and mathematical models play an important role in supporting efficient and transparent decision-making. In this review, we cover the past applications of modeling to island eradications, which range from large-scale prioritizations across groups of islands, to project-level decision-making tools. While quantitative models have been formulated and parameterized for a range of important problems, there are also critical research gaps. Many applications of quantitative modeling lack uncertainty analyses, and are therefore overconfident. Forecasting the ecosystem-wide impacts of species eradications is still extremely challenging, despite recent progress in the field. Overall, the field of quantitative modeling is well-developed for island eradication planning. Multiple practical modeling tools are available for, and are being applied to, a diverse suite of important decisions, and quantitative modeling is well placed to address pressing issues in the field.</p
