DENR Supports Nomination of Biri Rock Formations for UNESCO Global Geopark Status

TACLOBAN CITY — The Department of Environment and Natural Resources (DENR) regional office is advocating for the Biri Rock Formations in Northern Samar to be recognized as a UNESCO Global Geopark, aiming to enhance protection and global recognition of this significant natural landmark.

According to Philippines News Agency, DENR Eastern Visayas regional executive director, during a press briefing on Tuesday, the Biri Rock Formations’ nomination aligns with efforts to safeguard the site’s unique geological features, including its limestone walls. The formations are already part of the Biri Larosa Protected Landscape and Seascape, safeguarded under the Republic Act No. 11038, or the Expanded National Integrated Protected Areas System Act of 2018.

The Biri Rock Formations, accessed via an hour-long motorboat ride from Lavezares town, consist of seven distinct formations that have been recognized for their international geological significance. A 2010 study by the University of the Philippine National Institute of Geological Sciences highlighted the formations’ importance, with the Makadlaw rock estimated to be from the Early Miocene era, approximately 15-20 million years old.

The site’s most notable formations, including Magasang, Magsapad, and Bel-at, are not only visually striking but also play a critical role in protecting the island from the formidable waves of the Philippine Sea and San Bernardino Strait. This natural barrier is part of the broader “Biri Volcanic Complex.”

The push for geopark status gained momentum following a visit on May 24 by UNESCO National Commission of the Philippines Secretary-General Ivan Anthony Henares and other officials, who assessed the site’s potential. If successful, Biri Island would become the second UNESCO Global Geopark in the Philippines after Bohol Island.

UNESCO Global Geoparks are designated for their geological significance and managed under principles that emphasize protection, education, and sustainable development, providing a model for preserving natural sites while supporting local communities.
