Online maps of seagrass meadows at Hera, Timor-Leste are now available.

Blue Ventures (Timor-Leste), Project Seagrass and Seagrass-Watch, as part of the IKI SES project, collected field validation data using Seagrass-Watch subtidal drop-camera technology at a number of pre-determined mapping points.

Sharks keep a seagrass ecosystem healthy and able to respond to stresses. When seagrass is damaged, sharks assist recovery by reducing herbivory and allowing maintenance of goods and benefits.

Improving Approaches to Mapping Seagrass within the Great Barrier Reef: From Field to Spaceborne Earth Observation

Seagrass meadows are a key ecosystem of the Great Barrier Reef World Heritage Area, providing one of the natural heritage attributes underpinning the reef’s outstanding universal value. We reviewed approaches employed to date to create maps of seagrass meadows in the optically complex waters of the Great Barrier Reef and explored enhanced mapping approaches with a focus on emerging technologies, and key considerations for future mapping. Our review showed that field-based mapping of seagrass has traditionally been the most common approach in the GBRWHA, with few attempts to adopt remote sensing approaches and emerging technologies. Using a series of case studies to harness the power of machine- and deep-learning, we mapped seagrass cover with PlanetScope and UAV-captured imagery in a variety of settings. Using a machine-learning pixel-based classification coupled with a bootstrapping process, we were able to significantly improve maps of seagrass, particularly in low cover, fragmented and complex habitats. We also used deep-learning models to derive enhanced maps from UAV imagery. Combined, these lessons and emerging technologies show that more accurate and efficient seagrass mapping approaches are possible, producing maps of higher confidence for users and enabling the upscaling of seagrass mapping into the future.

Seagrass-Watch: Global Seagrass Observing Network is a not-for-profit organisation that monitors the status and trends in seagrass condition. The network has conducted over 5700 assessments at 418 sites across 26 countries, involving thousands of dedicated participants.

We strive to educate and collaborate with likeminded conservationists to make a difference environmentally and socially.
