Short description

Zorro is an interdisciplinary research program where marine ecologists, oceanographers, ecotoxicologists, environmental lawyers and environmental economists collaborate on issues related to the management and restoration of eelgrass ecosystems. The work is also carried out in close association with various authorities.

Among other things, Zorro has produced national guidelines for restoration and ecological compensation of eelgrass, a national action plan for eelgrass and over 40 scientific publications and popular science articles.

The Research Program Zorro

(Zostera restoration)

Interdisciplinary research about management and restoration of eelgrass in Sweden

Zorro is an interdisciplinary research program that started in 2011 at the University of Gothenburg. It has the goal to improve the management of coastal ecosystems with focus on eelgrass meadows along the Swedish west coast. The program constitutes a base for research collaboration between marine ecologists, oceanographers, ecotoxicologists, environmental legal scholars, and environmental economists about management and restoration of eelgrass ecosystems, and is carried out in close collaboration with the Country Administrative Board of Västra Götaland, and the Swedish Agency for Marine and Water management. The name ‘Zorro’ is constructed from the words ‘Zostera’ (the eelgrass genus) and ‘restoration’.

Today, more than 20 Swedish and international researchers and national and regional managers are collaborating in 6 different research projects coordinated by the program, with funds from national research councils, national authorities and the EU.  

The research program have produced national guidelines for restoration and ecological compensation of eelgrass, as well as a national action plan to protect eelgrass beds. The research has also resulted in over 40 scientific publications and popular science articles. Furthermore, Zorro conducts public outreach to spread information about eelgrass, why it is threatened and how it can be protected and restored. This work is carried out by researchers from the program giving lectures, through interviews in media, and through a number of films about eelgrass produced within the program.

(3/8 -21) Losses of eelgrass beds give rise to large emissions of carbon and nutrients

A new study published in the journal Ecosphere shows that losses of eelgrass meadows lead to sediment erosion and release of large amounts of carbon and nutrients.

(17/5-21) 80,000 eelgrass shoots planting started

The planting of over 80,000 eelgrass shoots has started at the sand-covered area at Lilla Askerön, in the municipality of Tjörn. The shoots will be planted by scuba divers and the work is expected to be completed within 2 months.

(12/3 -21) Eelgrass will be restored using 1800 tonnes of sand

The County Administrative Board of Västra Götaland and Gothenburg University are studying if coarse sand placed on top of the seafloor can help re-establish threatened eelgrass. The method will be tested at a small island in the municipality of Tjörn, 70 kilometers north of Gothenburg. This is the first time restoration of eelgrass using this sand coverage technique is  tested at large scale in Sweden.

Ongoing Research Projects

Preventing small-scale physical disturbances from causing large-scale turbidity and loss of coastal habitats (2020-2023)

Goal: To combine remote sensing, oceanographic modeling, ecological and legal studies to (1) try to identify thresholds ​​when small-scale physical disturbances causes large-scale resuspension of sediments with large ecological effects on e.g. eelgrass (2) assess if dumping of dredge material from recreational marinas constitute a major source for the ongoing spread of TBT and other contaminants to the environment, (3) develop a more sustainable management of the coastal environment that takes into account the cumulative effects of small-scale exploitation.

Genetic population structure of Baltic Sea eelgrass – urgent information for conservation of a foundation species under climate change (2020-2024)

Goal: to integrate new knowledge about eelgrass genetics with modeling of connectivity and how eelgrass distribution and demography can change due to future climate change. The project will use different modeling techniques that can provide support for prioritizing when eelgrass meadows should be protected or restored, and assess the ability of different meadows to recover and adapt to future environmental changes.

Seagrass as a natural protection against beach erosion (2019-2022)

Goal: to combine small-scale experiments in the laboratory, large-scale field studies, and biophysical models to study how eelgrass beds affect large-scale transport of sand and beach erosion, and determine whether eelgrass restoration can be used as a measure to counter beach erosion, which expected to increase due to climate change. In collaboration with authorities, the results will be used to develop guidelines for the conservation and restoration of eelgrass along wave exposed coasts, where the meadows' protection against beach erosion can be included in coastal zone planning.
