Tessa Mazor, who has recently submitted her PhD in Kark Group, has published along with other experts a paper in Ecological Applications about: Large-scale conservation planning in a multinational marine environment: cost matters

This study aims to provide an approach for including cost when planning large-scale Marine Protected Area (MPA) networks that span multiple countries. In order to include cost in conservation prioritization, we developed surrogates that account for revenue from multiple marine sectors: commercial fishing, noncommercial fishing, and aquaculture. We found that for less than 10% of the Sea’s area, our conservation targets can be achieved while incurring opportunity costs of less than 1%. In marine systems, we reveal that area is a poor cost surrogate and that the most effective surrogates are those that account for multiple sectors or stakeholders. Furthermore, our results indicate that including cost can greatly influence the selection of spatial priorities for marine conservation of threatened species.

Our PhD student Tessa, along with Salit, Hugh and research colleagues, have published a paper in PLoS One, titled: The crowded sea: incorporating multiple marine activities in conservation plans can significantly alter spatial priorities.

This paper explores how the inclusion of multiple marine activities can shape conservation plans. We used the entire Mediterranean territorial waters of Israel as a case study to compare four planning scenarios with increasing levels of complexity, where additional zones, threats and activities were added. We found that by including increasing numbers of marine activities and zones in the planning process, greater compromises are required to reach conservation objectives. This case study follows an illustrated framework for adopting a transparent systematic process to balance biodiversity goals and economic considerations within a country’s territorial waters. This work had important findings for Israel which is currently aiming to expand its current network of protected areas.

The first nest boxes are going into the trees for the 2014 breeding season! This project sees Salit Kark, along with research assistant Carla Archibald and Honours students Laura Cox and Emily Dayman, monitoring breeding of cavity nesting birds.

Salit Kark was profiled recently for her Australian Research Council grant, which looks at interactions that influence the spread of invasive species.
