Presidential Proclamation 413 declares September 26 of every year as Sierra Madre Day. This declaration is observed annually and spearheaded by the Save Sierra Madre Network Alliance, Inc. (SMNAI), a network of Indigenous Peoples and Non-Indigenous, People’s Organizations, Government Organizations, Civil Society Schools, Churches and Individuals committed to the protection and preservation of the Sierra Madre.
This is in response to the immense flooding in Metro Manila and the nearby LGUs caused by the Typhoon Ondoy, which were attributed to the continuous deforestation, degradation and destruction of the Sierra Madre Mountains.
This celebration is also in line with the Presidential pronouncement in his 2018 State of the Nation Address (SONA), earnestly encouraging initiatives of reducing vulnerabilities to hazards, and bolsters resilience on the impact of natural disasters and climate change.
This years’s theme is Buhay na Sierra Madre ay Buhay Nating Lahat” and Buhay na Kabundukan, Kaligtasan nating Lahat!”
