Project Seagrass and the Environmental Leadership of Cullen-Unsworth
The health of our oceans depends on ecosystems that often go unnoticed. Among the most critical yet overlooked are seagrass meadows, which provide essential services to both marine life and human populations. The work of Cullen-Unsworth, a distinguished marine biologist and former CEO of Project Seagrass, has been pivotal in shifting global attention toward the protection and restoration of these underwater grasslands.
Academic Foundation and Early Research
Cullen-Unsworth's journey in marine science began with a degree in marine biology from Newcastle University, followed by a Master's degree at Bangor University. She completed her doctorate at Essex University in 2007 before moving to Australia for post-doctoral research funded by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
While conducting research in Indonesia alongside Richard Unsworth, the focus was initially on corals and mangroves. However, a critical discovery redirected their trajectory: they realized that seagrasses supported a vast array of life that served as the primary protein source for local families. This realization highlighted the direct link between seagrass health and human food security.
The Evolution of Project Seagrass
Building on these insights, colleague Benjamin Jones laid the groundwork for what would become Project Seagrass, an international NGO and UK-registered charity. Under the leadership of Cullen-Unsworth as CEO, the organization has worked to elevate the status of seagrass from a niche interest to a global conservation priority.
In 2018, Cullen-Unsworth served as the prime author of a significant paper in the journal Science, calling for urgent international action to protect seagrass habitats. She has consistently argued against the "fluffy" perception of seagrass—the idea that they are merely habitats for charismatic species like seahorses—emphasizing instead their vital role as resources for the global fishing industry.
Ecological Importance and Human Impact
Seagrasses are fundamental to the survival of millions. Research contributed to by Cullen-Unsworth highlights the importance of these meadows for gleaning—a method of fishing in shallow water (no deeper than a person can stand) using basic gear or bare hands. Invertebrate gleaning within intertidal seagrass meadows provides a critical food supply for hundreds of millions of people worldwide.

Despite their value, seagrasses face numerous threats. In the UK, these plants are sometimes removed from beaches to make the coastline appear more picturesque, despite their ecological necessity. Furthermore, Cullen-Unsworth co-authored a 2018 paper warning about the environmental damage caused by British sewerage systems.
Innovation in Restoration
To combat the loss of these habitats, Project Seagrass has embraced technology. The organization utilizes underwater robots to plant seeds, facilitating the growth of new seagrass meadows. This innovative approach has gained governmental attention, with the Welsh government incorporating this work into their official conservation plans.
In recognition of her contributions to science and conservation, Cullen-Unsworth was identified as one of the BBC's 100 most influential women in 2024.

Frequently Asked Questions
What is gleaning in the context of seagrass meadows?
Gleaning is a form of fishing conducted in shallow water, typically no deeper than a person can stand, using basic gear or bare hands to collect invertebrates.
Why is the "fluffy" approach to seagrass conservation criticized?
The "fluffy" approach focuses on the aesthetic or cute appeal of species like seahorses. Cullen-Unsworth argues that the more essential argument is the role of seagrass as a critical resource for the fishing industry and human food security.
How is technology being used to restore seagrass?
Project Seagrass employs underwater robots to plant seeds that can grow into new seagrass meadows, aiding in the restoration of damaged ecosystems.
What threats do UK seagrasses face?
In the UK, seagrasses are threatened by environmental damage from sewerage and are sometimes manually removed from beaches for aesthetic reasons to make them look more picturesque.
Who founded Project Seagrass?
The foundations for the NGO were laid by Benjamin Jones, with Cullen-Unsworth playing a key role as a co-founder and later serving as the CEO.
