Biodiversitas 24: 1438-1449. Land Use Cover (LULC) maps using remote sensing technology became popular due to their contribution spatial information useful for threat determination, biodiversity conservation, landscape management. Our area interest this paper is the southern Philippines with no...

Litsea leytensis Merr. is an endemic and premium hardwood species in the Philippines used for wood carving. It a threatened that survival wild impossible with persistent causal factors. The study estimated probability of occurrence Laguna Quezon based on local knowledge, published records distribution, environmental variables using Maximum Entropy (MaxEnt) model. Six pre-models were generated: one climatic model, four partial models variable groups combined variables, full model 31 original...

Following the international protocol for establishment of permanent plots, a two-hectare biodiversity monitoring area (PBMA) was established inside Makiling Forest Reserve. Results intensive 100% inventory revealed that PBMA holds tremendous tree diversity. A total 155 species were identified. Of these, 148 are indigenous to Philippines with 47 endemics (30% endemism). The most abundant native in is Magabuyo (Celtis luzonica) 2,287 individuals, followed by Balobo (Diplodiscus paniculatus) ,...

The study analyzed the raindrop size distribution (DSD) measured by an optical Parsivel disdrometer in Southern Luzon, Philippines and utilized it to generate dual-pol relations for nearby Tagaytay radar.The were generated using two methods (Method 1 -gamma-based Method 2 -linear fitting), four timeintegration steps (1-, 2-, 5-, 10-min) datasets from periods (wet season single event).The resulting quantitative precipitation estimates (QPEs) calculated R(Z) compared rain gauge stations near...

Mangrove forests are crucial biologically-productive ecosystems facing global loss and widespread degradation. The Philippines is one of the top countries with most significant mangrove fragmentation rates, contributed by worsening catastrophic typhoons. This paper was conducted to assess post-disaster recovery forest in Matalom Maasin City Leyte Island, Philippines, after Super Typhoon Odette using Sentinel-2 imagery. Specifically, it aimed utilize synergy vegetation indices, biophysical...
