Volume 25 No. 2&3 – Compilation of Selected Forest Species from Vol. 1 Nos. 1-10, 1989
The Ecosystems Research and Development Bureau produced the first 10 issues of Research Information Series on Ecosystems in 1989. Since then, due to numerous requests for copies of said materials, we have ran out of copies and we have been reprinting them for our readers.

Five of the most requested titles are Lumbang, Almaciga, Akle, Bagtikan and White Lauan. In this reprinted version, we are featuring these forest species to meet current demands.

We are therefore publishing this compilation for school libraries or as a handy reference in public reading nooks or information centers. In its compiled form, this issue can be conveniently used by our readers.
