The DENR Office in Guimaras whose administrative jurisdiction covers the whole Province of Guimaras was established through the passage of the Provincial Development Council’s Resolution requesting for the establishment of an office within the Sub-province of Iloilo. The issuance of DENR Regional Administrative Order No. 251 dated October 11, 1990 created the Environment and Natural Resources District Office (ENRDO) for Guimaras. Consequently, it becomes a district office operating under the immediate supervision of the PENRO, Province of Iloilo.

            The dawning of the Provincial Environment and Natural Resources Office (PENRO)-Guimaras was realized upon the Provincehood of Guimaras where the District Office was elevated to the Provincial level pursuant to Special Order No. 83, dated January 27, 1993 issued by then, DENR Secretary Angel C. Alcala.From 1990 to 1993, a satellite office of DENR operated in the province of Guimaras.

Major improvements and expansion were undertaken at PENRO Guimaras Office since CY 2006. From a light material structure, the PENRO Guimaras Office is now a complex with two main buildings for the management services and technical services division, respectively. The PENRO Nursery was constructed at the left side of the DENR Compound. A nipa hut was also constructed as a support to senior citizen project and is also being utilized as information center

The organic office of PENRO Guimaras started with seven personnel. From years 2006 to 2015, there were thirteen warm bodies. The operation of the Office was reinforced by casual plantilla, contractual and job hire personnel.

On May 2015 the rationalization process was on its peak. The three (3) organic plantilla positions (PENR Officer, Administrative Officer IV and Accountant II) were increased into eighty-three (83) plantilla positions for the management and technical services divisions. On July 1, 2015, seven permanent personnel from PENRO Iloilo and the Regional Office were promoted to PENRO Guimaras plantilla positions. The two (2) Division Chiefs were appointed to their positions on July 24, 2017. Fifty-six (56) new entrants took oath as permanent personnel on August 6, 2017. Seven (7) personnel from other DENR Offices in Region 6 were promoted to Salary Grade 18 to 22 on September 8, 2015. Most of these new entrants were casual, contractual, and job hire personnel of the agency. At present, eighty (80) positions were already filled up. Three (3) positions are still vacant.


There were major changes in the management of PENRO Guimaras which started last January 2015. The organizational structure was changed from sectoral to functional. The Office was divided into two divisions namely the Management Services Division and the Technical Services Division.
