This year marks the 10th anniversary of the establishment of the ASEAN Centre for Biodiversity (ACB), with the theme, ACB and ASEAN Member States: A Decade of Cooperation on Biodiversity Conservation.  As part of the celebration, ACB organized a series of activities on 2 October 2015 at the College of Forestry and Natural Resources, University of the Philippines, Los Banos, Laguna. Such activities include the following: 1. Groundbreaking of the New ACB Headquarters Building; 2. Tree Growing Activity at the "Tree World"; 3. Awarding of the Zooming in on Biodiversity Winners; and 4. "Nawa'y Muli Tayong Makauwi," a musical theatre show on biodiversity conservation. Termed as the ACB Day, the event provided ACB with an opportunity to promote the milestones of the Centre, and a venue for the ASEAN Member States (AMS), ACB and its partner organizations and countries to get together and further strengthen their partnerships and reaffirm their commitments to conserve the rich biodiversity of the ASEAN region.
