RDEP 3: Program on Water Resources Management CY 2012


This study started last 2011 and is expected to be completed by year 2013. It generally aimed at transferring technologies on plantation establishment of bamboo, rattan and medicinal/economically important tree species. During the year, the following activities were undertaken:

⇒ Training for Upland Farmers Training on Bamboo and Rattan Plantation Establishment and Management was conducted in the Conference Room, CENR Office, Pagbilao, Quezon on November 28-29, 2012. It was attended and participated by farmers from different municipalities of Quezon, selected staff from DTI, President of Chamber of Commerce Quezon and Municipal Agriculture Officer of Gumaca. The two-day training aimed to transfer the technologies on plantation establishment of bamboo and rattan, specifically to strengthen the capability and knowledge level on production, utilization and plantation establishment of Bamboo and Rattan and to provide alternative technologies or enterprise development to the participants as their source of livelihood. Experts from Ecosystems Research and Development Bureau (ERDB) gave the lecture and field demo on bamboo. The introduction and identification of bamboo was discussed by Senior Science Research Specialist Ms. Cristina Roxas. She also gave the importance and usage of different bamboo species which will be a good input to the farmers. Mr. Paulino Umali, Science Research Specialist II lectured on Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 154 Propagation, Plantation Establishment and Harvesting of Bamboo. He also facilitated the hands-on in the propagation of different bamboo species using cuttings. Introduction, identification and propagation of Rattan species was discussed by the Supervising Science Research Specialist Forester Celedonio Dapla.

⇒ Establishment of Rattan Plantation Rattan plantation was established covering a total area of two (2) hectares located in Sitio Amao, Brgy Malicboy, Pagbilao, Quezon. 300 rattan species were planted, c omp o s e d o f Tagiktik (Calamus filispadix) and Pasan-pasan (Calamus ciphonophatus), 150 each.

⇒ Maintenance of Bamboo Plantation Bamboo plantations established at Sta. Catalina, Atimonan and Brgy. Mamala I, Sariaya, Quezon were maintained through weeding, brushing and data gathering. Developed bamboo shoots were observed on all four species namely: Anos (Schizostachyum lima), Bayog (Bambusa sp.), Laak (Bambusa philippinensis) and Puser (Cyrtochola puser). Based on the gathered data, Anos was observed to have the best performance among all species in terms of average percent survival, total number of culm shoots, average diameter and average height in marginal and productive area.

⇒ Clonal Seed Orchard Establishment Close monitoring of the one hundred fifty (150) Batikuling marcots was undertaken to ensure high survival and good quality Batikuling marcots for eventual outplanting in the identified clonal seed orchard area. Potted marcots were properly cared due to its sensitivity to insect infestation. Seventy-seven 77 Batikuling marcots were outplanted in the identified clonal seed orchard located at Quezon Protected Landscape, Malicboy, Pagbilao, Quezon with an area of about six hundred ninety three (693) square meters. Initial data on height and diameter was gathered.

⇒ Ramet / Hedge Garden Establishment Yakal Malibato (Shorea malibato) species was selected for the Detailed Accomplishments and/or Milestones Table E-4.

A total of 84 Yakal Malibato seedlings were outplanted in the 80 square meters area near the Clonal Nursery in Malicboy, Pagbilao, Quezon. Care, maintenance and protection of the established hedge garden were regularly done to ensure high survival. In the ramet multiplication area, a total of eighty-three (83) Kalantas (Toona calantas) marcots were outplanted in 83 sq.m area located in Quezon Protected Landscape, Malicboy, Pagbilao, Quezon. Initial data on height and diameter was gathered. The hedge gardens established in CY 2011 continuously provide the needed cuttings for the protocol development component of this study.

⇒ Provenance/Progeny Testing/Trial The selected species for the Provenance/Progeny study is the Kamagong (Diospyros discolor Willd.) species. K ama g o n g s e e d s collected from five (5) d i f f e r e n t s o u r c e s / p r o ve n a n c e s we r e brought to the Clonal Nursery in Malicboy, Pagbilao Quezon for germination.  1. Negros Oriental 4. San Pablo 2. Leyte 5. Bicol 3. Batangas

⇒ Development of protocol Malibato species was selected for the Development of Protocol study using non-mist method. As of this reporting total of five h u n d r e d (500) yakal m a l i b a t o c u t t i n g s were used f o r t h e a c t i v i t y using the 2 0 0 p pm IBAA rooting hormone. From the total number of cuttings used, three hundred eleven (311) cuttings already survived and now placed at the recovery area.

⇒ Maintenance of Established Provenance Plantation Maintenance activities such as weeding/brushing and gathering of growth data were employed in the established provenance plantation of Narra and Molave located in Silangang Malicboy, Pagbilao, Quezon Based on the computed average height and diameter of Narra, FC 10 or provenance coming from region 6 obtained the highest average height which is 2.18 m and average diameter which is 2.58 cm. On the other hand, the calculated highest average height and diameter of Molave species was 3.40 m (FC 10/region 3) and 5.71 cm (FC 15 region 8) respectively. Availability of seeds for the provenance study is the problem encountered in this project.

⇒ Preparation of Demonstration Area Two (2) plantation sites were established: agrofrestry and reforestation species, located in Brgay Ikiren, Pagbilao, Quezon. For agroforestry, species planted were jackfruit, lipote, ipil-ipil, coffee while for reforesteation, species planted were acacia, malaiknmo ⇒ Maintenance and Protection of Demonstration Areas Continuous maintenance and protection of forest trees (Rain Tree, Ipil-ipil, Kupang, Batino) and agroforestry seedlings (jackfruit, coffee) in the demonstration area thru ring weeding of individual species, brushing and clearing of grasses along the boundary of the area. Survival and health status of the two (2) established plantations (attack of pest and diseases) and other significant findings that affected the growth were always been monitored.

⇒ Database Database for mycorrhiza project have been regularly being updated thru which measurements on Height (H), Diameter (D) and Survival were periodically encoded, both for reforestation and agroforestry areas. The updated database was sent to ERDB thru electronic mail for checking and final consolidation in the national report.

⇒ Data Collection Individual tagging both of reforestation and agro forestry species have been done for easy identification by block number and treatment used for s p e c i e s s u b j e c t e d t o measurement, protection and maintenance. First data gathering of HD for both species was done after three (3) months of transplanting. Three (3) Soil samples from reforestation and agro-forestry areas were gathered during the 2nd, 3rd and 4th quarters of the year. These samples were submitted to ERDB for soil analysis. The gathering was done per block/per treatment (3 samples by species) with a total of 126 bags both for agroforestry and reforestation areas. The construction of the AWS has been started and installation is scheduled in January 2013.

⇒ Management of Data of the RDEP 2 Project Based on the data gathered from the nursery as initial data on Height Diamter and survival, and subsequent data gatherings conducted for the two (2) plantations, the matrix provided by ERDB Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 159 for average Height, Diameter and percent (%) survival of the species planted per block. ⇒ Installation of Automated Weather Station (AWS) The construction of the AWS shelter started only on the 3rd week of December 2012 and due to the problem encountered in the roofing where the solar panel will be attached, the installation is scheduled in January 2013.


Project 3: Riparian Zone Rehabilitation to Minimize Erosion and Sedimentation and Improve Water Quality

     This study aims to evaluate the effectiveness of various riparian zone/ stream bank rehabilitation measures in minimizing erosion and sedimentation of watersheds. A total of four (4) experimental plots were established in the riparian zone areas in Sitio Logpond, Barangay Binahaan, Pagbilao, Quezon using heliconia, lemon grass and ornamental bamboo species. For the year CY 2012, data on rainfall, soil erosion rate and foliage development of treatment plants were gathered in order to assess/ evaluate the effectiveness of the selected species as a rehabilitation measures in minimizing soil erosion and sedimentation on riparian areas.

⇒ Establishment of experimental plots, site preparation and outplanting of treatment plants on riparian zone in Sitio Logpond, Barangay Binahaan, Pagbilao, Quezon Experimental plots for the study were established in Sitio Logpond, Barangay Binahaan, Pagbilao, Quezon following the prescribed field lay out presented in Table E-5. This was for the planting of three selected indigenous species namely: Heleconia, Lemon Grass and Ornamental Bamboo to monitor their impact in controlling soil erosion on riparian zone and to determine which of them can effectively minimize soil erosion and sedimentation. Experimental field layout was set in an RCBD Design in three replicates Field Lay Out). Replication was represented by a Block. Each Block contains three plots. Each plot has a dimension of 3m x 5m with an isolation of 1 meter in between plots. Clearing of the chosen experimental area from weeds and other plant debris was done before the site was delineated and out planting was carried out. Spacing used in between individual plants was 0.5m x Detailed Accomplishments and/or Milestones Table E-=. FIELD LAY OUT: Randomized Complete Block Design 3 x 3 BLOCK 1 P1S3 CONTROL BLOCK1 P2S1 BLOCK1 P3S2 CONTROL BLOCK2 P1S2 BLOCK2 P2S3 BLOCK2 P3S1 BLOCK3 P1S1 BLOCK3 P2S3 BLOCK3 P3S2 CONTROL Where: B = Block; P = Plot; S = Species; C = Control; S1 = Heleconia; S2 = Lemon grass; S3 = Bamboo; CY 2012 Annual Report - DENR CALABARZON Region 160 0.5m so that each plot contains 45 plants altogether.


⇒ Data sets collected, monitored and analysed- To quantify the effectiveness of treatment species in controlling / minimizing soil erosion, the following parameters were monitored and measured: soil erosion rate, rainfall intensity and frequency and foliage growth. A temporary data collector was hired and trained in using modified devices for daily rainfall monitoring and bi-monthly assessment of soil erosion rate and maintenance of the area. Data collection is being supervised by a Technical Staff involved in the project. As of this reporting, 12 sets of bi-monthly assessment of soil erosion rate was conducted, 12 months daily rainfall monitoring was done, and ten monthly assessment of foliage growth was accomplished.


⇒ Soil Erosion Rate Assessment Assessment of Soil Erosion Rate was conducted from February 29, 2012 to December 1, 2012. Results show that, there are positive and negative SER values that came out from the first period to the last period of data collection. These findings could be attributed to instability of surface soil which was impacted by heavy rainfall. The type of soil in the study area is sandy loam which during rainy days can be vulnerable to displacement to lower areas. Despite the planted species which are expected to protect and keep the soil binded, movement of the soil was not prevented. Annex E-1 presents the summary of Soil Erosion Rate on riparian area rehabilitated with heliconia, lemon grass and ornamental bamboo in So. Logpond, Brgy Binahaan, Pagbilao, Quezon.

⇒ Monitoring and assessment of rainfall occurrences Table E-6 shows the monitored rainfall occurrences in millimeter in the study area from January to December, 2012. The Table further shows that rainfall intensity is higher during months of January to March, July, September, October, and November and lesser during months of April, May, June and August. Based from the results, it Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 161 can be deduced that dry period i n the area falls from April to June, while rainy period covers the remaining months. It was also observed that rainfall intensity in August was low despite that this month is within the rainy period. This occurrence could be a consequence of climate change. It is expected that high rainfall occurrences could trigger soil erosion on vulnerable areas like the riparian.


⇒ Monitoring and Assessment of Foliage Development of Treatment Plants Monthly assessment of foliage development of treatment plants in percentage was done to determine the extent of the area they can cover and protect. This is also to know which of these plants can effectively control or minimize erosion caused by rainfall. Table E-7 shows the summary of the average foliage development of treatment plants from February to December 2012. Table E-7 reveals that in the tenth month of assessing foliage d e v e l o pme n t o f t reatment plants, bamboo (S3) provided the highest percentage which is 100%. This is followed by Heleconia (S1) which obtained 83% then by Lemon Grass (S2) which gave the least foliage development of 72%. The Table also shows that from October to December, foliage development of Lemon Grass (S2) had decreased while the two other treatments, S1 & S3 showed a consistent increase. Control plots on the other hand, have 100% weeds cover from February to December. Variation in the obtained percentage of foliage growth could be attributed to plants’ responses to unpredictable climatic conditions that prevail in the area. Small leaves and the presence of thick and hard stem, made bamboo tolerant and resilient to strong wind and too much water brought by rain why their growth surpassed that of the two other treatment plants. Lemon grass was affected by too much water on their stem which made them weak and soft and caused them to fall down. Slow growth that was exhibited by Heleconia in some plots at early stage resulted to inferior foliage development. Foliage or crown development of a plant plays an important role as mediator or buffer against direct impact of heavy rain on soil which can trigger soil erosion to occur.


 Project 4: Stakeholders’ Participation in Water Resources Protection and Development Program- The study on Stakeholders’ Participation in Water Resources Protection and Development Program was completed this year 2012. As of to date, terminal report is being prepared. A total of Php 52,000.00 was released for the implementation of this project. No problem or any difficulty was encountered during the implementation of the project. All research activities were carried out according to work plan.

⇒ Attendance to the National and Regional Levelling-Off activity- The “National Levelling-Off Workshop on the Implementation of Priority Research, Development and Extension Program (RDEP)” was conducted by the Ecosystems Research and Development Bureau (ERDB) last February 28 to March 3, 2011. This was Detailed Accomplishments and/or Milestones Condition of Lemon grass in Block 1 CY 2012 Annual Report - DENR CALABARZON Region 163 followed by another leveling-off session in order to brief and orient the study leader on how social research is to be carried out using an effective method of generating the necessary data and/or information.

⇒ Reconnaissance survey During the reconnaissance survey, possible watersheds in the CALABARZON Region were identified for assessment and from which a model site was selected. Each identified watershed was evaluated according to the management schemes/strategies and/or practices and stakeholders’ participation.

⇒ Assessment of watersheds- The six (6) watersheds that were characterized and evaluated according to management approaches by various stakeholders are the following:

1. Lagnas Watershed, Dolores, Quezon The Pinagdalayan River and Cristalino Spring are the main sources of water of the municipality of Dolores, Quezon. During summer months, water scarcity is being experienced by the local consumers. In Brgy. Sta. Lucia, Dolores, Quezon, potable water is being sourced from different springs coming from Lagnas Watershed by the natural pressure/gravity force to supply the 1,200 households. Each household is charged of Php 30 per month as user’s fee without any meter installed. A development project on water resources to be funded by OBAMA fund will be undertaken. The project will be spearheaded by the Department of Social Welfare with an amount of Php 500,000.00 per barangay and a 20% share from the Municipal fund, amounting to 187,000.00 per barangay. The barangay counterpart is the “bayanihan system (labor)” with a value of Php 113,000.00. The total budget for the said project amounted to Php 800,000.00 per barangay.

2. Amao Creek, Pagbilao, Quezon Amao Creek is one of the natural water systems in Sitio Amao, Brgy. Binahaan, Pagbilao, Quezon. A water intake tank was installed within the ERDS clonal nursery area from which the water through a gravity force is being used for all the nursery activities and by the adjacent community. The households in the area are not paying any amount on the water they are consuming. Twenty (20) residents are also dependent on free flowing water from Amao Creek to support their car washing business along the road.

3. Mt. Malarayat Forest Reserve, Lipa City, Batangas The Mt. Malarayat Forest Reserve is the largest forest reserve in the province of Batangas, covering a total area of Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 164 1,275 hectares. It was declared as a forest reserve in 1928. Through time, these resources may considerably become exhausted. It was projected that the domestic water demand may reach up to 62,433 cubic meters with a 3% population increase by year 2020. Four (4) headwaters were identified covering four barangays. As part of the protection goal for the Malarayat Forest Reserve, the area is being protected by various stakeholders. Through City Ordinance No. 53 of 2007, the Lipa Headwaters Council was created in order to establish a database on water sources, educate the public regarding the protection of water sources, undertake research activities to enhance water security, and reward all those who will institute watershed protection activities. The Mt. Malarayat-Malepunyo Watershed Protection Council (MMMWPC) was also organized to fully protect the said forest reserve. A biodiversity assessment of the Mt. Malarayat-Malepunyo was conducted by the DENR-R4A and PUSOD, Inc. (formerly Babilonia-Wilner Foundation) to address the vulnerabilities of Malarayat ecosystem and dependent communities to climate change. Based on the assessment, a total of 89 species surveyed are endemic and this include 7 out of 16 mammal species observed in the area; 35 out of 63 species of birds; 24 out of 35 species of herpeto fauna; and 23 out of 122 plant species. The Inter-governmental Panel on Climate Change (IPCC) reported that some species of flora and fauna demonstrate considerable changes in the timing and behavior of their biological events (i.e. phenology), as they respond to climate change. According to some key informants, a total of 135 ownership claims over some portions of the Mt. Malarayat-Malepunyo was identified as one of the threats to the existing ecosystems of the forest reserve.

4. Malabanban and Lubigan Springs, San Pablo City Based on the report of the San Pablo City Water District, water yield for domestic and commercial use in the city are being supported by the existing seven (7) freshwater lakes and eleven (11) springs in the area. Water production wells and deep pumping stations were constructed to augment the water needs in the city. According to the City Environment and Natural Resources Officer, the Malabanban and Lubigan Springs are protected through multi-sectoral reforestation activity. Only 10% survival was observed on the outplanted trees in Malabanban watershed due to its rocky feature. Annual bush fire was also observed in the area. Water scarcity is being experienced only during el nino period. Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 165 The city government had prepared a Tourism Entrepreneur Zone Management Plan in order to sustainably develop the existing seven lakes in the city and make it an incomegenerating source of the city government.

5. Binahaan Watershed, Pagbilao, Quezon Binahaan Watershed covers an area of about 1,489.38 hectares with six (6) sub-catchments such as Catapang; Busilak; Binahaan Munti; Malinta; Binahaan Malaki; and Low-land. It has an elevation of 420 meters above sea level (asl). For the past six years, it has recorded the highest rainfall of about 506.39 mm. It supplies the water requirements of Team Energy Coal Power Plant for their cooling system, and the water demand for irrigation and domestic use of the communities. To fulfill the commitment of the coal plant as part of its Corporate Social Responsibility (CSR) over the protection of the environment, regular protection (i.e. patrolling activity) and carrying out of successive reforestation activities were undertaken within the Binahaan Watershed. The Daloy Biyaya (formerly Tubig Biyaya Irrigators Association) which was created to help the farmers in the area. Through the association, the farmers were able to secure a loan amounting to Php 3M in 2010. The said financial grant covered the development/construction of distribution canals or patubig for farm crop production.

6. Maulawin Spring Protected Landscape (MSPL), Guinayangan, Quezon The Maulawin Spring Protected Landscape (MSPL) is formerly known as the Maulawin Spring Watershed Forest Reserve. Through Proclamation No. 295 (April 23, 2000), it was proclaimed as Maulawin Spring Protected Landscape under the NIPAS category. It has a total area of 149.01 hectares with an elevation of 250 to 500 meters above sea level. It is located at Barangays Himbubulo West, San Pedro 1 and Magsaysay, Guinayangan, Quezon. It is geographically located at 13° 55´ longitude and 122°25´ latitude. It is traversed by numerous rivers and creeks. The Maulawin, Hiwasayan and Prenza Rivers are the major sources of surface water for domestic consumption in the locality. The Maulawin River is the only source of potable water of the Metro Poblacion of Guinayangan, Quezon. A total of 1,216 concessionaires from six (6) barangays are being serviced by Guinayangan Water District (GWD), of which, 932 (77 %) and 284 (23 %) are active and inactive, respectively. The MSPL is considered as priority area for biodiversity conservation under the classification of Insufficient Data (ID) based on the results of the National Biodiversity Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 166 Conservation Priority Setting Project of DENR-PAWB, UP Center for Integrative and Development Studies, and Conservation International Philippines. The management and development of water resources in MSPL were dependent on the participation and involvement of different stakeholders. Records show that several resolutions were passed by the Protected Area Management Board for ecological and economic considerations.

⇒ Model Site Among the six w a t e r s h e d s ident i f ied, the Maulawin Spring P r o t e c t e d Landscape was selected as model site. Selection was based on the n u m b e r o f s t a k e h o l d e r s ’ participation and level of being proactive in water resources’ protection and development as manifested in the number of management schemes adopted by different stakeholders. By virtue of Presidential Proclamation No. 365 dated January 2, 1939, the model site was proclaimed as Maulawin Spring Watershed Forest Reserve (MSWFR). Then, on April 23, 2000, under the P r e s i d e n t i a l Proclamation No. 295, it was declared as Maulawin Spring Protected Landscape (MSPL). It is within the a d m i n i s t r a t i v e jurisdiction of the Municipal i ty of G u i n a y a n g a n , Q u e z o n a n d specifically located at Brgys. Himbubulo and Magsaysay, Guinayangan, Quezon. It lies about 260 kilometers southeast of Manila. The geographical location is 13°55’ longitude and 122°25’ latitude. It can be reached for about ten to twenty minutes hike through several trails from Brgys. Calimpak, Sisi and Gabok. The area is also accessible by land transportation during the dry months of the year through the barangay roads of Brgys. Himbubulo and Sta. Cruz, Guinayangan, Quezon. Detailed Accomplishments and/or Milestones CY 2012 Annual Report - DENR CALABARZON Region 167 It has a total land area of 149.01 hectares. At present, more or less one half of which is a secondary growth of mixed forest dominated by Dipterocarp species. It falls under the second climatic type wherein it is characterized by two pronounced seasons, dry from February to May and wet during the rest of the year.
