The Forestry Herbarium and Wood Collection presents a collection of roughly 13,000 specimens consisting of 135 families, 645 genera with more than 1,500 species, and 700 specimens of Palms (18 genera and 103 species).

It safeguards priceless collections dating back to the 1920s from various tropical forests in the Philippines, e.g. Mt. Isarog in Camarines Sur, Mt. Pulag in Benguet, Mt. Malarayat in Batangas, Mt. Guiting-guiting in Sibuyan Island, Romblon and the legendary Mt. Makiling in Laguna.

The collection also includes donated specimens from foreign countries, i.e. Thailand Botanical Herbarium, and of course more than 600 palm and rattan specimens collected by Museum curator Dr. Edwino S. Fernando.
