It was during RD Machacon’s time that the Wood Industry Development Authority (WIDA) was created in 1985.  Forester Francisco C. Manaog was designated as OIC Regional Director of WIDA covering the island provinces of Samar and Leyte in Region 8.  Later on, four (4) WIDA Sub-district offices were created in provinces with operating timber licensees.  These were: Dolores, Eastern Samar; Basey, Samar; Laoang, Northern Samar; and San Juan, Southern Leyte.  This set-up was shortlived when the EDSA revolution happened in Feb.25, 1986.
