Get Involved

Participate in our Eyes of the Reef Marianas training program!

Get trained in how to identify and report coral reef threats.

    • Eyes of the Reef (EOR) Marianas is a program that trains community members on identifying impacts on coral reefs and techniques for reporting impacts to coral managers. The program covers topics such as coral bleaching, coral disease, marine debris, crown-of-thorns starfish, and nuisance species. Training materials are online, and in person training events are open to the public.

  • If you love sharing your passion for the natural world with students, then consider becoming a volunteer docent at the Ritidian National Wildlife Refuge! They need volunteers on Thursdays and Fridays to help lead field trips in the refuge. Many of us on the GCRI team have assisted with Ritidian field trips in the past and they are always a lot of fun and a great opportunity to help young students connect with nature!

    Check out their website to learn more, or call 671-355-5096

    The Ritidian Wildlife Refuge also hosts monthly beach cleanups open to anyone over the age of 18. Click here to check out their schedule for upcoming beach cleanups

  • The Department of Agriculture hosts hunting derbies several times per year to help cull the population of feral pigs and deer. These species are not native to the island and contribute to the deforestation of Guam’s inland forests, which in turn contributes to increased erosion and sedimentation that impacts local reefs. Participating in these derbies may not seem like your typical way of helping corals, but everything is connected, from ridge to reef, so addressing threats in upland areas can also positively impact coastal areas!

    Check out the Department of Agriculture Division of Aquatic and Wildlife Resources Facebook page for updates on the next derby

  • Crown-of-thorns sea stars (COTS) are a nuisance species that can cause significant damage to coral reef ecosystems. If you are a confident scuba diver (Advanced Open Water certification level minimum) and want to help control COTS outbreaks, consider becoming part of the Guam Crown-of-Thorns Rapid Response Team!

  • Calling all fishers! Did you know that you can help keep Guam’s fish around for generations to come simply by sharing a photo of your catch? It’s true; all you have to do is submit photos of your catch with a ruler or other object in the frame for reference. From there, Sea Grant staff can record measurements and identify the species you caught. If you have a particularly large catch, you can also call in and request a staff member to meet up with you to collect data in person! Keeping track of this information is a great way to keep tabs on how local fish populations are doing and identify the best course of action to keep these species around for future generations of fishers.

    If you would like to participate, please check out @guam_fish on Instagram, or reach out to project coordinator Leilani Sablan at sablanl9009@triton.uog.edu

    • We periodically host Eyes of the Reef (EOR) trainings, which anyone is welcomed to join. Please follow the Guam Coral Reef Initiative on Facebook or Instagram @guamcoralreefs to see if we have an upcoming EOR training that may coincide with your trip. These trainings are in English and educate participants on basic coral reef information, and how to identify and report reef threats.

    • Check out the Guam Museum, and they also sometimes host seminars called HITA talks, which stands for Heritage, Ideas, Tradition, Arts. These are free and open to the public. For more event updates, you can also follow them on Facebook and Instagram @guammuseum

    • For nature walks on land, we recommend:

      • the Asan Ridge hiking trail- there's good signage pointing out native plants and their traditional uses. The hike ends with a great view of the ocean and a sign that talks about coral reefs.

      • Visit the Ritidian National Wildlife Refuge - it's a beautiful beach and beautiful nature area to explore, and they often offer free tours and sometimes organize beach cleanups.

    • There are some wonderful beaches and snorkel spots to explore! Here are some recommended sites:

      • Tumon Bay - Ypao Beach Park 

      • Tumon Bay - Matapang Beach Park 

      • Tumon Bay - Gun Beach - make sure the waves are calm before you snorkel here

      • Piti Bomb Holes Marine Preserve - Fish Eye Marine Park

      • At each of these beaches, we have posted signs with educational information and ocean safety tips! See if you can find all 4 signs.

      • We also have 3 other signs posted around the island - see if you can find all 7!

    • Use our Tumon Bay BINGO and Piti Fish Eye BINGO sheets to get familiar with local marine life and learn their CHamoru and English names. See how many species on the sheet you can spot during your time visiting.

  • We unfortunately do not offer group volunteering activies at this time. However, we do occasionally host volunteer events that are open to the public, including groups. Please follow our Facebook or Instagram @guamcoralreefs to stay updated with upcoming volunteer events. For example, we always host a cleanup for Coastal Cleanup Day, which is the third Saturday in September every year.

      • All you need is a trash bag (or reusable bucket) and a glove to get started!

      • To make cleanups even more effective, we highly recommend using the Clean Swell app to track what kinds of trash you pick up. This gets entered into a global database and helps inform policy aimed at reducing marine debris!

  • Unfortunately, we do not offer this at the moment. However, here are a few ideas that we hope may help you find what you are looking for:

    • If you are a tourist visiting Guam and want to volunteer while you visit, please see some ideas for places to volunteer in the two FAQs above.
