Research, Development and Extension Programs: In further support to this agenda, the Ecosystems Research and Development sector was engaged on the following research and development extension programs and activities:

• RDEP 2: Program on Sustainable Upland and Coastal Areas Development

Sub-Program: Program on bamboo and rattan, medicinal plants and other economical important species for livelihood and ecologically stability

Study 1: Survey of bamboo stands and establishment of a national database of economically important bamboo species in the Philippines

The study aims at providing the necessary data on the extent, distribution, availability, and location of commercially valuable bamboo species in the CALABARZON region.

For the conduct of this Study, a Regional Team was created, which composed of personnel from Decision Support System Office (DSSO), Forest Management Sector, and PENRO/CENRO in Laguna. Dr. Lamberta N. Meraña of ERDS-Region IV-A acted as the Study Leader. The Province of Laguna was chosen as the Pilot Area.

Dr. Lamberta N. Meraña of ERDS-Region IV-A acted as the Study Leader. The Province of Laguna was chosen as the Pilot Area.

→Among the municipalities and specific barangays considered for survey are the following: Brgys. Taytay and Oobi in Majayjay; Brgy. Bucal in Nagcarlan; Brgy. San Jose in San Pablo City; Brgys. Cansuso, Pauwin, Lumot, and Sisilmin in Cavinti; Brgys. San Antonio and Longos in Kalayaan; Brgys. Kapatahan and Macombo in Paete; Brgy. Galalan in Pangil; Brgy. Matikiw in Pakil; Brgy. Minayutan in Famy; Bgrys. Parang na Buho, Santiago, Laurel, Cueva, and Paco in Sta. Maria; Brgys. Novaliches and Ilayang Sungi in Liliw; and municipality of Rizal.

→More than 900 clumps of mixed bamboo stands were surveyed/ inventoried within the eight (8) barangays in 6 selected municipalities in the province of Laguna. Bamboo stands in Majayjay, Laguna are situated along riverbanks and water channel beside upland vegetable farms. Most of which is Gigantichloa levis species. Kawayang baging almost covers the entire riparian (upland) in barangay Matikiw, Pakil while Kawayang tinik was observed growing along foot trails and municipal roads (lowland). High concentration of Buho (Schizostachyum lumampao) was found in barangay Ilayang Sungi, Liliw.

Bamboo stands were concentrated in small area above upland farms. In the municipality of Sta. Maria, mixed species of bamboo were found concentrated in one are only. Accordingly, most were replaced with Mahogany trees and others destroyed by Typhoon Milenyo, or harvested by local residents. In barangay Minayutan, Famy, most of the Giant bamboo were situated along Inawasan River. On the other hand, bamboo clumps of Buhong Cinâ were predominantly situated along roadsides and creeks, with other species such as Tewanak in Tala, Rizal. (See Table III-30 for the detailed results of the survey per municipality per barangay).
Below are photos of Bamboo stands found in selected municipalities within the province of Laguna.

For this year, the Region was able to generate the Regional Database of Bamboo Stands and produced one (1) GIS-based map of Bamboo stands in the province of Laguna. (See Figures III-20 and III-21).

Study 3: Establishment of pilot plantation of bamboo and rattan With a general objective of transferring technologies on bamboo and rattan plantations establishment, the sector will establish Bamboo and Rattan plantations and at the same time train upland tree farmers on plantation establishment and management.

→The Quezon Protected Landscape (QPL) in Malicboy, Pagbilao, Quezon was chosen as the plantation site. The area was surveyed and basic characteristics were gathered such as topography/aspect, soil type drainage system, current landuses, climate, and tree species within. (see below Table III-31).

→Four (4) Pilot Plantations of Bamboo were established for this year, a 100% accomplishment based on target. A total of 240 bamboo seedlings (90-Puser; 90-Anos; 60-Bayog) were outplanted in productive area of PACBRMA, Brgy. Mamala 1, Sariaya, Quezon and another 240 bamboo seedlings (90-Puser; 90-Anos; 60-Bayog) were outplanted in marginal area of CBFM, Brgy. Sta. Catalina, Atimonan. Quezon. The Percentage survival in the marginal area is 60.78%, while in the productive area is 68.86%.

Sub-program 3: Development of strategies for the production of quality planting materials

Project 1: Tree Improvement Program for Indigenous and Endangered species

The project generally aims at upgrading and enhancing the sustainable sources of quality germplasm and vegetative materials for planting stock production of some demand-driven indigenous/endangered species nationwide.

→Clonal Seed Orchard Establishment: Tree improvement approaches were used in the selection of site and species for this activity. Sitio Amao, Malicboy in Quezon was selected as the project site and Bani (Pongamia pinnata) as the species. Basic descriptions of the site and the species were also gathered. (Table III-32).

A total of one hundred (100) Bani species were grafted to produce planting stocks for the seed orchard establishment and were outplanted in Quezon Protected Landscape (QPL) Brgy, Malicboy, Pagbilao, Quezon with an area of 1,250 sq. m. and 3 x 5 m spacing .

120312 8

A total of one hundred (100) Bani species were grafted to produce planting stocks for the seed orchard establishment and were outplanted in Quezon Protected Landscape (QPL) Brgy, Malicboy, Pagbilao, Quezon with an area of 1,250 sq. m. and 3 x 5 m spacing .

→Ramet/Hedge Garden Establishment: For easy protection and maintenance, the site for hedge garden is situated at the Clonal Nursery in Sitio Amao, Malicboy, Quezon covering about 5,000 sq.m. As of this quarter, three (3) hedge gardens were established and planted with Lanete, Bani, and White Lauan. Germplasm collection of Lanete is currently being done in preparation for outplanting.

→For the Provenance/Progeny Testing/Trials and Protocol Development, one hundred thirty-five (135) White lauan (Shorea contorta) species were outplanted in 2,500 sq.m. area in Brgy. Sapinit, Pagbilao, Quezon.

Three (3) blocks were established, each blocks have 7 meter spacing for isolation. Forty-five species (45) were outsourced from three (3) provinces namely: Aurora, Laguna, and Quezon. Each has di stinct di f f erence s in geographical locati on and climatic factors. The figure below provides for the image of experimental design for this study. The blue ci rcle represents species from Aurora, the red and yellow represent species Laguna and Quezon, respectively. 120312 9

Sub-program 4: Improving Reforestation Technologies/Strategies and Enhancing Productivity of Upland Areas

Project 1: Application of mycorrhiza and other Soil Amelioration for Improving Reforestation and Agroforestation in the Uplands

The project specifically aimed at field testing and demonstrating the effectiveness of the application of mycorrhiza (biofertilizer) in significantly enhancing survival of different tree and agroforestry species in the upland. Highlights of accomplishments for this year were as follows:

 →Nursery and Demonstration area selection: Clonal Nursery in Malicboy, Quezon was chosen as the nursery area due to the existing facilities and proximity to the demonstration area. The demonstration farm would be in a private land covering 5.2 hectares. The area has a flat rolling terrain, a marginal grassland, and accessible to the national road.

→Preparation of seedbeds inside the misting chamber of the Clonal Nursery in Quezon:sowing and broadcasting of seeds of Batino, Kupang, Raintree, and Ipil-ipil, innoculation using various mycorrhizal treaments (1,2,3 and 4). (see photos).

Seed germinates were maintained and protected in the Clonal Nursery and outplanted to the Demo area located at Brgy. Ikerin, Pagbilao, Quezon.
