Action Group

To tackle the global crisis facing kelp forests we need to work at a global scale, and broadly develop and implement solutions. To this end, we have established the global 

Green Gravel Action Group.

This international group of researchers will trial Green Gravel restoration in different regions. Together we will communicate research findings and develop general protocols for different kelp species and locations. This will facilitate broad implementation and uptake of the tool.

Wernberg Lab at UWA and SeaForester are co-leading the GGAG. SeaForester's prime focus is on global commercialisation and upscaling of the green gravel technique which is in line with its Blue Front Yard approach to seaforestation. Research institutions, companies and municipalities interested in rolling out seaweed restoration in their regions can partner with SeaForester to secure funding, implement local infrastructure, and establish local partnerships.

on implications for conservation.


Postdoctoral researcher with the Wernberg Lab at UWA. George works at the intersection of seaweed ecology, genomics and seaweed-associated microbial health for restoration. She has led seaweed restoration projects on the East and West coasts of Australia.


Holding a BSc in Marine Science Mason is the Lab Coordinator for the Wernberg Lab at UWA. He handles outreach & communication for the GGAG. Along with the logistics, aquaria management and field work aspects of UWA's Green Gravel project. 


Pål is founder and CEO of SeaForester. He was born on the Norwegian island of Frøya, and learned about seaweed cultivation while working in Asia. A few years later he moved to Portugal where he also founded Seaweed Energy Solutions, a pioneer in seaweed cultivation in Europe based in Norway.

After completing her MSc at the University of Aveiro, Portugal. Inês joined SeaForester in 2018 where she has acquired hands on experience in seaweed ecology. She leads the coordination of public research funds and supports project development and implementation, communication and fundraising.

João is a marine ecologist at MARE-Leiria, Portugal.He is a researcher in several  international marine reforestation projects and was directly involved in the first successful restoration trial using stones in Southern Europe. He leads research and development of Seaforester's restoration actions, from the nurseries to the ocean.
