  • Towards science-based coastal management: Tipping points for seagrass conservation and restoration

    2015-2019. The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS)

    Principal Investigator: Dr. Eduardo Infantes

    Dense seagrass meadows facilitate their own growth by improving light conditions – they attenuate currents and waves, trap suspended particles and stabilize sediments. If such a system is perturbed to a degree that it cannot maintain suitable conditions, a threshold for collapse is reached beyond which natural recovery becomes extremely difficult. Although this theory is now well-developed, quantitative assessment of feedback strength and related consequences are lacking. This project aims to empirically quantify how much vegetation can be lost before a system collapse and how much should be revegetated to improve the water quality for seagrass recovery. Novel insights about seagrass-sediment-hydrodynamic interactions will be achieved combining field data, experiments and an empirically parameterized numerical model.

  • Coastal mapping using drones

    2017-2018. Kosterhavet National Park, Länsstyrelsen Västra Götaland

    Principal Investigator: Dr. Eduardo Infantes

    Kosterhavet National Park is a marine national park with the aim of maintaining the biodiversity of the area. The management plan for the park contains a lot of conservation goals and one is to maintain and increase the l such as Zostera marina (eelgrass) beds in the park. In 2008, mapping of the eelgrass beds was carried before the establishment of the park, but no mapping has been done after that. It is now time to reinvestigate the areas of eelgrass and look for the actual distribution in the national park. The aim of this project is to develop a methodology using drones and underwater cameras for mapping eelgrass on the Kosterhavet National Park.

  • No-net-loss and restoration of marine habitats: Legal and ecological constraints and solutions

    2012-2015. The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS)

    Principal Investigator: Dr. Per-Olav Moksnes

    Eelgrass beds play a key role in Swedish coastal ecosystems for marine biodiversity and natural resources by providing habitat and food for a number of organisms, including several commercial species. These ecosystems are presently impacted by eutrophication, and over 50% of the eelgrass has been lost from the Swedish NW coast. Because of slow horizontal growth and possibly due to local regime shifts, natural recovery of eelgrass may not occur even if growing conditions improve. The main goal of the proposed project is to assess if transplantation of live eelgrass could be used for restoration of eelgrass ecosystems in Sweden, both to restore eelgrass in areas where it has been lost, and to establish eelgrass in new areas to compensate for habitat lost to coastal exploitation. Using a multidisciplinary team of scientist and managers, and a combination of model and empirical studies, we aim to (1) identify environmental threshold conditions for eelgrass survival, and potential feed-back mechanism that prevent the return of eelgrass, and (2) evaluate a number transplantation methods successfully used in other parts of the world to find the best methods for Swedish conditions. Based on these results, and in dialog with coastal managers, we will develop a detailed management guideline regarding methods for site-selection, transplantation and evaluation of results for eelgrass restoration in Sweden.
