Distribution modeling of Rafflesia schadenbergiana and Rafflesia consueloea using multi criteria decision analysis-analytical hierarchy process in GIS

The identification of potential habitats the largest and smallest flowering parasitic Rafflesia in Philippines is a prerequisite conservation species preservation their which have been being degraded due to anthropogenic activities climate change. This research aimed at revealing possible habitat suitability for schadenbergiana Göppert ex Hieron consueloae Galindon, Ong Fernando throughout using Geographic Information Systems (GIS). selection criteria this were based on four parameters (elevation, annual rainfall, temperature, land use / classification) identified during extensive literature review. generated map shows that optimal growth can be observed with temperature range 20–22°C while thrive within 24°C 25°C. importance these was evaluated pairwise comparison method final weight computed each criterion. Setting up values suiting subject followed by weighted overlay analysis. output distribution species.
