This study aimed to determine the angiosperm trees found in Mt. Riwata Barangay Dalig, Cardona, and Rizal. This study was conducted at the University of Rizal System Cardona Campus during School Year, 2018-2019. The identification and classification of trees were held at Barangay, Dalig, Cardona, Rizal. The subject of the study focused mainly on the angiosperm existing at Mt. Riwata, in the determination of the tree species, random sampling plots measuring 40mx50m was made at Mt. Riwata. Diversity indices were determined using Simpson's Index and Shannon-Weiner's Index. Based on the computed average of vegetation in Mt. Riwata in Cardona, Rizal in terms of diameter and height of trees, Plot 1 having a highest total average diameter of 12.42cm and highest total average height of 3.75m, while the lowest total average diameter of 2.99cm and lowest total average of 1.05m can be found on Plot 9. Based on the calculated Simpson Index of 0.125148089 shows that there less diversity among the plot because the value is nearer to 0. Whereas, the calculated Shannon Weiner Index 4.71434516 or roughly 5 shows that there is 5 percent diversity species per plot band verbally interpreted as moderately distributed. As a resulted of the study, it is recommended to encourage the people to take care the entire Mt. Riwata and also the plant existing in the area. Make a study about the Ethno Botanical Survey of different angiosperm herbs along Mt. Riwata of Cardona, Rizal. And inform the resident of Barangay Dalig to avoid dispersion of waste in every place in Mt. Riwata.
