Rosslyn Barr

Chair of Trustees

About Rosslyn

Rosslyn loves nature, and has always been inspired by the ocean. She is an avid traveller with happy memories of rock-pooling on Scottish Islands, whale watching, penguin spotting in the Falklands and watching baby turtles dash towards the ocean during a stunning Ascension sunrise.

A zoology graduate, specialising in marine biology, Rosslyn spent 20 years in the corporate world focused on strategy execution and change management. The volunteering she did with Sharklab Malta and the Edinburgh Shoreline project opened her eyes to the impact that marine conservation work could have. She has supported the environment sector since, allowing her to make best use of her experience and networks, alongside a life-long knowledge and passion for nature conservation.

Her current roles include Board Member of Sharklab Malta, Steering Committee member for the Edinburgh Shoreline project, and Project Manager for a proposed combined Shoreline and Heriot-Watt project in the Forth. In all roles she aims is to create opportunities for people from all walks of life to enjoy our beautiful oceans and participate in their conservation.

She is delighted to be joining the Project Seagrass Board of Trustees. As a shark lover, she knows how important seagrass is as a safe environment for all marine creatures, having seen a rescued Nursehound shelter in Neptune grass (Posidonia oceanica) in Malta. She was also fascinated to learn that the gaels in Scotland used seagrass to thatch their roofs as it was stronger than straw!

Jake Davies


About Jake

Growing up along the coast of Pen Llŷn, North Wales has meant that the marine environment has always been a big part of Jake’s life. His passion for the marine environment led him to study Marine Biology at Bangor University, where he’s been part of numerous projects to better understand a range of marine species and habitats from seagrass to sharks. In 2016, Jake joined Project Seagrass as an Intern where he assisted in data collection and spreading awareness of seagrass in North Wales. Following the internship, he continued to work closely with Project Seagrass as a regional ambassador.

His passion for marine life, exploring the underwater world and technology doesn’t stop there. As a professional scuba diver and underwater videographer (JDScuba), he reveals what’s found beneath the waves to wider audiences via social media and TV. Bringing together his enjoyment of research and providing engaging content to bridge the two areas together.

He is honoured to be joining the Project Seagrass Board of Trustees. He hopes to bring his hours of knowledge gained from spending time amongst the seagrass leaves, experience of media and use of different technologies to help in engaging wider audiences in finding out more about the importance of Seagrass habitats and the valuable groundbreaking work carried out by Project Seagrass.

Mike Furness


About Mike

Mike’s early career aspiration was to have a job that required wellies, so it wasn’t too surprising that he ended up with an ecology degree and boots to suit. After an early spell in the water industry, Mike’s career has been split between forestry, countryside access and environmental consulting, with a recent focus on environmental impact assessments.

In 1992 he set up, and still helps to run, a volunteer conservation group managing an award-winning local nature reserve in Oxfordshire. Mike hopes that his long experience of working with volunteers, of practical conservation and environmental projects, and hundreds of grant applications will be of value to Project Seagrass.

Picking seagrass spathes by torchlight at 3am in water barely 4″ deep, Mike was surprised by a matchbox-sized creature repeatedly knocking his searching fingers. A plucky, over-ambitious ‘squidlet’ was letting Mike know who’s home this was. Young, squid became a regular delight during early morning seed collection.

Sebastian Hennige

Associate Scientist

About Sebastian

Sebastian is a Marine Scientist at the University of Edinburgh with over 15 years of experience investigating the impacts of man-made stressors and climate change to marine ecosystems. This has included tropical and temperate systems, and work from research vessels, SCUBA diving, and snorkelling. In a time of rapidly changing oceans, we need to understand how ecosystems are changing, what we can do to mitigate this, and what this will mean to how we interact with and manage them in the future. To understand how ecosystems will change, we need to understand their environmental limits now and potential to grow under different conditions. This will not only impact where they can grow, but directly inform restoration efforts.
