Forestland Boundary Delineation and Landuse Assessment CY 2011


The Forestland Boundary Delineation and Assessment (FLBDA) is a priority program of the DENR since CY 2000 under DAO No. 2000-24 to delineate and establish the permanent limits of forestland boundaries on the grounds. Presently, it was continued under DAO No. 2008-24, a revised guidelines for the assessment and delineation of boundaries between forestlands, national parks and agricultural lands. The provision also stated to finish the whole activity in this year 2011.

This project aims to delineate and assess all existing Forestland and A & D lands and determine their present status and create a base map for better management and development within the region. This also aims to provide more accurate information on the total area of Forestlands and A & D lands in each province.

The project is specifically conducted by the Region Land Evaluation Party (LEP) . The LEP teams and other DENR personnel are combined to compose the Regional Assessment and Delineation Teams (RADTs) to execute the project regionwide.

For the year CY 2011, the RAD Teams were tasked to conduct the delineation and assessment activities for the remaining targets in the province of Quezon under regular funds how ever, 2010 budget which became continuing appropriation in 2011 w as tagged under NPSENRMP. For that budget 64 ki lometers and 1,294 kilometers target, respectively both located in the province of Quezon.

Based on the guidelines, the Geographic Information System (GIS) Team of LEP prepared all the maps needed before the actual ground assessment and delineation. Thematic maps were prepared and composed of the following:

1) Legal and Regulatory;
2) Land Use/Land Cover;
3) Slope;
4) Elevation;
5) Geologic/Soil;
6) Drainage/River Network;
7) Road Network;
8) Geo-Hazard;
9) Base Map with existing tenurial instrument;
10) Topographic/DMA;
11) Climate;
12) Cadastre.

Thematic maps were used to prepare the indicative maps and determine the current potential of Forestland and A & D lands within 500 meters on both sides. The current land cover or vegetation, slope and land use, especially if it is already a built-up area, were noted and marked on the map. During the actual assessment (primary data gathering), those information from secondary data were validated and actual ground situation were noted.

The pre-determined Forestland and A & D boundaries were relocated and the actual status in terms of land use on both sides of the boundary line (500 meters) was assessed. The areas previously determined which passed the criteria on either reversion to forestland or to be released as A & D were validated and staked (using PVC pipes) based on the prescribed dimension.

Before the actual field assessment, orientation/workshop was conducted by the RAD Teams to CENRO/PENRO personnel. Meetings and coordination were conducted to LGUs and stakeholders.

This year 2011, the team were able to del ineate a total of 354 kilometers; 64 kms. in the municipalities of San Narciso (43), and Unisan (21). Also, delineated 290 kms. in the remaining municipalities of Guinyangan (47), Gumaca (94), Lopez (54) and Padre Burgos/Pagbilao (95).

In the case of the municipality of San Narciso, there were a total of nine (9) blocks of forestlands, eight (8) of which were retained as forestland and only one (1) was recommended as non-conforming to forestland. Sample of blocks is presented below as Table F-18 and sample maps shows as Figures III-12 & III-13.


For the municipality of Unisan, a total of 11 blocks were assessed and delineated, seven (7) of which were retained as forestland and four (4) of which were allocated as non-conforming to forestland.


Likewise, also assessed a total of 1,057 kilometers of forestland boundaries in the following municipalities; Agdangan (6), Atimonan (64), Calauag (17), Guinyangan (61), Gumaca (94), Infanta (56), Jomalig (22), Lopez (54), Lucena (54), Padre Burgos/ Pagbilao (139), Patnanungan (145), Pitogo (17), Real (177), San Andres (23), San Francisco (21), Tagkawayan (36) and Tayabas (71). The slight increased of 39 kilometers on the actual area or boundary assessed in the municipalities of Padre Burgos, 28 and 11 kilometers in Patnanungan, all in the province of Quezon. The sample maps of assessed area iare presented as Figures III- 14 and III-15.


The numbers of planted Polyvinyl Chloride (PVC) pipe were also taken into account. A total of 870 PVC pipes were planted by the RAD Teams in all respective target areas in the province of Quezon.


Further, for this year CY 2011, the Region has al ready completed in the assessment and deliniation of forestland boundaries within the CALABARZON Region. A total of 4,000 kilometers of forestland Cavite—136 kms.; Laguna—105 kms.; Batangas—639 kms.; Rizal—310 kms.; and Quezon—2,810 kms. These are composed of 372 blocks of assessed and delineated forestland, 21 blocks of which are nonconforming to forestland while 351 blocks are retained to forestland covering an area of approximately 14, 924.98 hectares. (See Annex III- 16.)


The CALABARZON Region has a total land area of 1,622,861 hectares, out of these, 570,913 hectares or 35% are forestland. Therefore, if the result of this project will be approved, the region will have a total of 443,158 hectares or 27% forestland area, a reduction in forestland area of 8%. The map showing the assessed and delineated forestland area is presented below as Figure III-16.
