THESIS ABSTRACT – Modeling Species Distribution of Shorea guiso (Blanco) Blume and Parashorea malaanonan (Blanco) Merr in Mount Makiling Forest Reserve using MaxentClimate change is regarded as one of the most significant drivers of loss in biodiversity and altered forest ecosystems. This study aimed to model the current species distribution of two dipterocarp species in Mount Makiling Forest Reserve as well as the future distribution under different climate emission scenarios and global climate models.A machine-learning algorithm based on the principle of maximum entropy (Maxent) was used to generate the potential distributions of selected species. The species occurrence records of two dipterocarp species and sets of bioclimatic and physical variables were entered to Maxent software to predict the current and future distribution of the dipterocarp species. The variables were initially reduced and selected using Principal Component Analysis (PCA).Moreover, two global climate models (GCMs) and climate emission scenarios (RCP4.5 and RCP8.5) projected to 2050 and 2070 were utilized in the study. The Maxent models of dipterocarp species were evaluated using Receiver Operating Characteristics Area Under Curve (AUC) and True Skill Statistics (TSS).The models AUC values of Parashorea malaanonan ranges from 0.9885 to 0.9933 while 0.9352 to 0.9860 for Shorea guiso, which is both greater than 0.5 indicating better model prediction than random. Based on the criteria of TSS, models of Bagtikan (Parashorea malaanonan) and Guijo (Shorea guiso) both performed excellent.The Maxent models predict that suitable areas for Bagtikan will decline by 2050 and 2070 under RCP4.5 and RCP 8.5. On the other hand, Guijo was found to benefit from future climate with increasing suitable areas.The findings of this study will provide initial understanding on how climate change affects the distribution of threatened species such as dipterocarps. It can also be used as a basis and assist decision-making to better conserve the potential habitat of the species in current and future climate scenarios.Keywords: species distribution, Maximum Entropy, dipterocarp species, climate change
FEED runs a number of Students and Volunteers for the Environment (SAVE); Corporate Social Responsibility (CSR) – such as mangrove planting for coastal protection or ridge reforestation plantings; One Child, One Tree; Bio-Intensive Gardens (BIG) for nutrition in public elementary schools and other spaces; Climate Change Survival 101 and other LIVING LEGACY programs – customised environmental engagement activities for individuals and organisations interested in contributing to climate change adaptation efforts and greening critical areas such as watersheds, ridges, and reefs that all require rehabilitation.
