As of October 2025, the Sierra Madre mountain range in the Philippines is actively undergoing reforestation and conservation efforts, with assistance from a variety of groups. The Tourism Promotions Board (TPB) Philippines carried out corporate social responsibility activities, such as planting 1,250 native tree seedlings in the Southern Sierra Madre, notably in Brgy. San Andres, Tanay, and Rizal. This is part of a larger Adopt-A-Seedling Program that includes community training and nursery installation to sustain these seedlings for three years. These projects seek to protect the Sierra Madre as a green tourism attraction, critical watershed, and natural storm barrier for several communities.
