Seagrass Loss and Restoration: Case Studies from the Indo-Pacific Webinar

Open Communications for the Ocean (with support from the NOAA National MPA Center)

Seagrass meadows are vital to food security, livelihoods, and coastal resilience across the Indo-Pacific. They provide gleaning and small-scale fishing opportunities for the region’s most food-insecure households, as well as essential habitat for commercial fisheries. They also protect coastal communities by reducing wave energy and erosion, buffering storm surges, stabilizing sediments, and filtering pollutants, pathogens, and excess nutrients to improve water quality.

Greater Southeast Asian has the largest global extent of tropical seagrass, but over half is degraded. Restoration projects are underway across the region, with varying degrees of success. A recent synthesis of this work identified several factors—including species, restoration methods, light levels, wave energy, and water depth—that are associated with greater survival and establishment of restored seagrass.

In this webinar seagrass restoration experts Dr. Rohani Ambo-Rappe and Dr. Jennifer Verduin will share lessons from two of the most extensive and well-studied seagrass restoration programs in the region, including:

• The use of simple, low-cost restoration methods in the Spermonde Archipelago, South Sulawesi, Indonesia

• Work to replant foundational seagrass species in partnership with Indigenous traditional owners in Shark Bay, Western Australia.

The presenters will discuss why seagrass loss occurred, describe the restoration approaches used and their successes and challenges, and share lessons learned about what works, what doesn’t, and why. The webinar will conclude with a live Q&A, providing attendees an opportunity to ask the presenters questions.

Subtitles will be available in over 30 languages.
