Celebrate Guam Year of the Reef 2018 with us!


Celebrate our island's coral reefs all year long - Guam Year of the Reef 2018

Guam’s coral reefs are a precious resource – they create vital habitat for fishes and other marine species, support social and cultural activities, provide the backbone for Guam’s tourism industry, and protect our coastlines from storms and erosion. Despite their value, they are greatly threatened by both local stressors – such as pollution, overfishing, and recreational misuse – and the impacts of global climate change and ocean acidification. This year, our island recognizes Guam Year of the Reef 2018 (GYOR) in honor of our valuable coral reef ecosystems and in answer to the global call to action to better protect and manage coral reefs. The International Coral Reef Initiative has declared 2018 as the third International Year of the Reef. Local natural resource managers, scientists, and community leaders are working together to recognize this designation on Guam. Throughout 2018, Guam will host a series of public events and opportunities for everyone to get involved in coral reef conservation and management and improve the condition of our local reefs. More information and a calendar of events is available on our events page here. Updates will also be posted on the GYOR Facebook page (@GuamYearoftheReef2018). Like our page to stay informed!

Our coral reefs give us so much to celebrate - fun days at the beach, underwater adventures, coastal protection, family traditions, and more.




Guam joins the international community to celebrate the 3rd International Year of the Reef (IYOR). 

The first International Year of the Reef was in 1997 and occurs every ten years. Government agencies, school groups, non-governmental organizations, and our community can come together to reach the IYOR goals:
strengthen awareness globally about the value of, and threats to, coral reefs and associated ecosystems;
promote partnerships between governments, the private sector, academia and civil society on the management of coral reefs;
identify and implement effective management strategies for conservation, increased resiliency and sustainable use of these ecosystems and promoting best practices; and
share information on best practices in relation to sustainable coral reef management.

June: Restoring Reefs and Watersheds

Did you know that Guam has lost 80% of the coral on its seaward slopes since 1960? Due to climate change and local stressors such as pollution, our coral reefs continue to decline. Between 2013-2015, Guam lost half of its branching staghorn corals. Guam’s natural resource managers and local researchers are now investigating innovative ways to actively restore our island’s coral reef habitats. Guam’s ocean- based coral nursery, located within the Piti Bomb Holes Marine Preserve, has hosted over 1,000 fragments of five species of branching staghorn corals. The fragments are transplanted to the nursery, where they are able to grow larger in favorable conditions before being outplanted to reefs. The nursery also contains juvenile corals that were bred in the University of Guam Marine Lab using coral spawn from Guam’s reefs. In 2015, after a mass spawning, more than 1,000 coral larvae were settled onto tiles and moved to the nursery, where they have a safe environment to grow before being transplanted.
In addition to coral restoration, Guam’s natural resource managers are also actively restoring watersheds. Pollution, storm water, and sediments run-off the land and onto adjacent coral reefs. These inputs can smother corals, cause harmful algal blooms, and result in coral disease outbreaks. One approach to decreasing the amount of pollution and sediments that reach the sea is through watershed restoration. This includes increasing the amount of vegetation on Guam’s land by replanting slopes and reducing impacts of wildland fires and offroading. By planting trees and other native plants, we can prevent erosion; the roots of plants will hold the soil in place and prevent runoff of sediments onto the reefs when it rains.

Conservation Officers are responsible for enforcing the island’s natural resource regulations. Signs are posted at each of the marine preserves outlining the laws and regulations of that preserve. Violators of marine preserve regulations are subject to fines up $500, or imprisonment up to 90 days. If you see a violation, please report it to the Department of Agriculture Division of Aquatic and Wildlife Resources (DAWR) by calling 688-3297.

Food Fishes of the Mariana Islands - Click here to a digital copy of posters of food fishes of the Mariana Islands that are often found in both homes and markets. Learn the names of different fishes in CHamoru, English, Carolinian, and more. Physical copies of this poster are available at the Guam Department of Agriculture’s Division of Aquatic and Wildlife Resources office in Mangilao. 
Kuentusi I Hanom – Speaking to Water - Humanities Guåhan’s project, Kuentusi I Hanom, Speaking to Water seeks to privilege the voices and perspectives of indigenous CHamoru people and other Micronesians—those who trace their heritage to the Federated States of Micronesia, Palau and the Marshall Islands—about the cultural importance and meaning of water in their lives. Their voices, which are heard in stories, chants, poetry, personal narratives, reflections and other forms of creative expression, were collected and curated for initial presentation in an interactive digital kiosk as part of our Water/Ways and Hita I Hanom exhibitions held at the Guam Museum in 2017. Kuentusi I Hanom is a collaborative pilot project between Humanities Guåhan and the Smithsonian Institution Traveling Exhibition Service through funding from the Smithsonian Asian Pacific American Center.
