SummaryFieldwork on the distribution, status and ecology of birds was conducted in the northern Sierra Madre mountain range, Luzon, Philippines, during March–May 1991 and March-May 1992. The findings show the area to be one of the most important for conservation of threatened species of birds in all Asia. The results are here combined with evidence from earlier surveys by other searchers. Fourteen threatened and 18 near-threatened species are now known from the area. This paper reports on all the threatened and near-threatened resident species of the island of Luzon, with special emphasis on their occurrence in the Sierra Madre mountains. In addition, the paper treats species with very limited global distribution that breed in Luzon, and lists species of forest birds endemic to the Philippines that have not previously been reported from the Sierra Madre mountains. Maps show the known sites for 17 species of special concern for conservation. New data on the altitudinal distribution of threatened and near-threatened species suggest that it is essential to protect primary forest at all elevations.

A critical review of the PCA’s extensive R & D findings, and field-extension experience, particularly, the Small Coconut Farms Development Project or SCFDP (1990 - 1998) was done.  The analysis revealed several key points relevant to pursue a sustained coconut rehabilitation of 750,000 hectares (ha.) @ a 5-year cycle in the wet and intermediate growing zones  with judicious fertilization (crop nutrition management). These major points are: (1)  at least 2 million (M) ha of current stands of coconut ( more than 95 % local tall varieties) have been suffering from widespread multi-deficiency of plant nutrients such as nitrogen, chloride, sulfur, potassium, phosphorus and micronutrients like boron, zinc and copper;  (2) as such, this is a major growth and yield-limiting  factor   that   limits   the  average   annual  coconut productivity (40 nuts tree or 1 ton copra/ha); (3)  the average performance (1992-95) of the SCFDP farms showed that coconut productivity increased to 91 nuts/tree (from 35 nuts) or to 3.01 tons copra/ha (from only 0.94) after at least 3 years of regular annual application of fertilizers; in  1998 ( post-rehabilitation of 3 years) yields dropped to 70 nuts/tree or 2.21 copra/ha; (4) onwards to year 2010, without management, these SCFDP farms  are predicted to further drop to 25.9 nuts/tree ( 0.70 ton copra/ha/yr), based on the estimate 8-9% annual reduction rate of yield; and (5) apparently, nationwide, the SCFDP experience  had shown that the soil nutrient-poor coconut farms are only capable of producing only about 1/3 of its achievable yield of 85 – 120 nuts/tree ( 2 –3 tons copra/ha), annually.

We describe Begonia tandangii, a new species of Begonia sect. Baryandra from the Sierra Madre Mountain Range of Luzon Island, the Philippines. Begonia tandangii has a close resemblance to B. fenicis in gross morphology, differing in having leaf margin sparsely fringed with minute hairs (vs. glabrous or with minute hairs only on teeth) and capsules with broadly-ovate outline and an acuminate apex (vs. capsules with broadly-obovate outline and a rounded to truncate apex). Phylogenetic analyses of Philippines species of sect. Baryandra based on ITS sequences revealed that B. tandangii was clearly separated from B. fenicis. Begonia tandangii is currently known only from the type locality in a coastal forest of Baler, Aurora Province, which is in the neighborhood of Aurora Memorial National Park.

This research investigated the outcomes and social effects of a community-based development project in the form of a rice-based community intervention. Conducted in Regions 1, 6, and 10 in the Philippines, it employed mixed methods to gather quantitative and qualitative data concurrently from 86 randomly sampled farmer-cooperators and 20 purposively sampled key informants who were project implementers and facilitators. The project improved the farmer-cooperators’ human capital and social capital. They had high to very high knowledge of the component technologies of the PalayCheck System, as well as corn, mushroom, and vegetable production, after the project was implemented. PalayCheck is a rice integrated crop management system that presents the key technologies and management practices as Key Checks, which farmers need to learn, check, and share. The t-test showed a highly significant increase in almost all of the production technologies except for duck raising and bitter gourd production, which were only mildly significant. There were also significant increases in their groups and networks, trust and solidarity, collective action and cooperation, and social cohesion and inclusion after the project. Moreover, there was a highly significant increase in the farmer-cooperators’ social capital. However, the number of conflicts or disputes among the farmer-cooperators and the members of the farmer association was only mildly significant. The project also provided economic benefits to the farmer-cooperators, such as an increase in yields and incomes, through their continued adoption of the production technologies taught during training. The results further show that the increase in yields was sustained except in certain years when some of the farmer-cooperators experienced low yields due to pest problems, drought, typhoons, and other calamities. Overall, the paired sample t-test revealed a highly significant increase in mean yields in Year 1 to Year 5 after the project than before the project in the three regions. Participation and empowerment outcomes were also observed, such as greater access to information, resources, support services, and training and employment opportunities as well as improved participation in project-related decision-making and community activities.

Abstract. Forest lands play crucial roles in nutrient recycling and climate regulation. The change of closed canopy forests to open canopy forests may indicate disturbance within the closed canopy forest. Within the local context of the Philippines, few studies have been conducted to monitor changes in closed canopy forest lands. Efforts to do so are limited by the spatial extent, remoteness and ruggedness of closed canopy forests. Satellite imagery can cover the spatial extent of forest lands as well as provide constant revisit periods for monitoring. However, while multispectral imaging can detect changes in land cover, it has limitations when detecting the subtler change from closed canopy to open canopy forest cover. This study aims to provide baseline spectral characterization of a closed canopy forest in the Philippines. For this study, a hyperspectral sensor (EO1-Hyperion) with 198 band channels ranging from 426.82 nm to 2395.50 nm and a pixel size of 30 m was used to characterize the spectral variations of closed canopy forest, open canopy forest, shrubs and cropland in Northern Sierra Madre, Philippines. Multiple endmember spectral mixture analysis (MESMA) was employed to sort the image into classes as well as to characterize intra-spectral variations among the identified classes. Spectral library endmembers were assembled, optimized and used to classify the image. The spectral libraries were optimized by using Endmember Average Root Mean Square Error (EAR) , Minimum Average Spectral Angle (MASA) and Iterative Endmember Selection (IES). Results overall agreement is 0.56 for EAR and IES and kappa coefficient is at 0.4.
