Research paper thumbnail of Species Diversity and Assessment of the Ethnobotanical Uses of Arecales At the Peak of Mt Manunggal, Cebu, Philippines

Palms, specifically provide us with various uses that may or may not be common to us. As part of the Central Cebu National Park, Mt. Manunggal is protected by Republic Act 8457 which is a law for the protection and conservation of some selected areas in Cebu, Philippines. This research wishes to know if this law has been properly implemented in Mt. Manunggal by measuring the species richness and diversity of the species under palm family that are present at the peak of the mountain. Additionally, this research aims to identify how the locals make use of the palm species in the area. Species of the order Arecales were inspected and identified using their distinctive morphology. Palm biodiversity was measured using Simpson’s index, Simpson’s index of diversity, Simpson’s reciprocal index and Shannon-Weiner index. For the ethnobotany, locals were interviewed and a table of the ethnobotanical uses of each species was made. It was found out that Arecales has a low biodiversity in the peak of the mountain. The species under it are most commonly used by the locals as food and medicine.

This leads to a decrease in areas allotted for planting. Alternative ways for growing plants have been introduced to maximize planting despite the shortage of space; one of which is the hydroponics system. With hydroponics, the substrate used is water instead of soil. The study aims to compare the effectiveness of hydroponics as a medium for growth compared to the traditional soil medium. Six stems of malunggay (Moringa oleifera) were used in the study. Three of which were used in the hydroponics set-up, while the other three were used in the soil set-up. All set-ups were added with ten mL of fertilizer, containing 13.0 % nitrogen, 13.0 % phosphate, and 2.00 % soluble potash. Ten days after planting, the fresh and dry weight of each stem were measured and compared to the original weight. The malunggay stems grown in the hydroponics set-up had a greater average weight difference between the original weight and the fresh weight than the malunggay stems grown in soil. The greater difference signifies a greater assimilation of nutrients. This implies that hydroponics is a more effective method for growing M. oleifera stem. However, it is recommended that more time should be allotted in conducting the study for more observable differences on the growth of the malunggay stem.
