Research and Development


 In the background is a man-made mini forest, an experimental forest currently plantedto different indigenous and endemic species of forest trees and non-timber forest species. Indigenous forest species like  dao, ilang-ilang, pili, molave , malabuho, narra and white lauan including softwood and shrubs are present. The endemic forest tree species are mahogany, yemane, mangium and bagrass. Most of these trees species were 15-20 years old. Some non-timber species were also planted along the creek like bamboo and rattan mixed with non-forest species like kaong and anahaw.



 Relevant research, development, and extension towards a healthy environment and sustainable natural 

resources for an improved quality of life 



To provide appropriate technology and information through research, development , and extension towards the enhance productivity and  sustainability of natural resources and protection of environment for the improvement of quality of life of Filipinos  



The Ecosystems Research and Development Service was created on June 10, 1987 pursuant to Executive Order No. 192, otherwise known as the Reorganization Act of the Dept. of Environment and Natural Resources. The Research Service then had two divisions. The Ecosystems Resources Research Division and the Technology Transfer Division.

In year 1999, Technical Services was created as one of the administrative units of DENR Regional Offices pursuant to DENR Administrative Order No. 99-14 and 99-52 which realigned the various divisions and other units in the regional offices with their corresponding redefined functions. The Lands Management Division (LMD) and the Forestry Resources Conservation Division (FRCD) joined Ecosystems Research and Development Division (forn\mer ERRD) and Technology Transfer and Information Division (former TTD) were grouped to make up the Technical Services.

The creation of Coastal Marine Management Office (CMMO) through DENR Administrative No. 8, S. of 20202 gave way to the addition of the Coastal and Marine Management Division as another division to the Technical Services.

Dept. Administrative Order No. 1 S. of 1988, had been restated in DAO No. 2002-27 in November of the same year, which deployed divisions of DENR Regional office to various sectors provided in Executive Order 192. In which case, ERCD (ERRD then), TTD (TTID then) and the CMMD composed the REsearch Service.

Later in 2003, CCMD was integrated with the Protected Areas and Wildlife and Coastal Zone Management Service (formerly PAWS), thereby reducing manpower of the Research Service to just two divisions, the ERRD and TTD.

The formulation and implementation of an integrated research program relating to Philippine ecosystems and natural resources such as water bodies, land and forests, as holistic and interdisciplinary fields of inquiry is the man concern of the ERDS.

The Research Service involves the generation and development of technologies relevant to the sustainable use of our ecosystems and natural resource. As a technology generating agency, ERDS fosters information exchange with and transfer of technology to various government agencies, LGUs, NGOs, private entrepreneurs, researchers, students and stakeholder in different localities in the region.

Likewise, it promotes partnership between DENR and the local government units through the Community-Based Resource Management Project.

Located at Kalisan Park, in Barangay Sagpon, ERDS is strategically located near the boundary of Legazpi City and Daraga, Albay. The area is located at the back of the Bicol University campus, approximately 500 meters form the national road and about 10 minute ride to the city commercial center or the nearest arirport. The are is walking distance from Camp Simeon Ola, Legazpi City. It is bounded by Sagumayon River on the East, Sitio Bagong Lipat on the South, Barangay Sagpon on the West and the Municipality of Daraga on the North.

   cClonal Propagation Facility

 Showcases a revolutionalized plantation technology on forestry which utilized the clonal multiplication technology (CMT) for the production of superior quality planting stocks of gmelina, mahogany, narra and indigenous species like sakat and sambualuan. It has the advantage of producing stocks with uniform growth, uniform quality and high yield. The nursery has a potential capacity  of 40,000 seedlings per year.

  Experimental Forest 

An approximate 10-hectare area planted to 38 different forest tree species in eleven plantations. Seeds of important forest trees can be collected from this man-made forest.

 ERDS Mini Library

 Provides scientific literature services (SLS). Open for public use 8 hours/day on weekdays

Laboratory Services (Seed Testing)

Conducts seed collection, processing, and propagation of forest tree species; determines seed viability; monitors growth and survival of seedlings taking into consideration parameters like: germinative energy, percent moisture content, germination capacity, and percent survival in the nursery; conducts seed testing; implements studies on seed storage; conduct lecture on seed technologies

 DENR Kalikasan Park 

Serves as an outdoor laboratory for students and scientists from within and outside the region. Ecotours are allowed. Kiosk, tree house and open picnic ground can be used by the public. At its outskirts are the 1901 American reservoir, tombs of Japanese soldiers, and the World War II tunnel (now the San Lorenzo Ruiz Peace Shrine).

 Seed Production Area (SPA) for Rattan  

Matured stands of rattan (Calamus merrilii) are maintained at the ERDS compound. This SPA is capable of producing 10 million seeds every year.
