GLYDEL GIDIE C. Floral Biodiversity Assessment of the Riparian Ecosystem of Ylang-Ylang River Watershed, Cavite, Philippines. Undergraduate Thesis. Bachelor of Science in Environmental Science. Cavite State University, Indang, Cavite June 2019. Adviser: For. Junser P. Magpantay.
The study was conducted in the riparian ecosystem of Ylang-Ylang River Watershed (YYRW) from August 2016 to March 2019. Specifically, it aimed to: (1) describe the vegetation of YYRW using vegetation index; (2) identify the flora species in the riparian ecosystem of YYRW; (3) assess the distribution of flora\ species in YYRW according to richness, evenness, abundance, and dominance; and (4) identify the indigenous plant species and its category.
The Normalized Difference Vegetation Index (NDVI), through the use of Landsat@ imagery year 2017 and ArcMap 10.5, was calculated to analyze the vegetation cover of YYRW And identification of flora species was done using quadrat sampling method. in total, 45 sampling sites were established every 2 kilometers of the riparian zones in YYRW.
The vegetation in YYRW ranges from low to high NDVI with a value of -0.40634 to 1. Among the four local government units, Silang has the highest vegetation cover while Dasmarinas City, General Trias City and Imus City have low vegetation cover due to {and conversion into built-up areas. A total of 722 flora; species were identified and categorized into trees, intermediate, and understory. Among the identified floral species, exotic flora\ species (64%) have a greater number than indigenous flora species 936%).
The computed Shannon Weiner Diversity index in YYRW has a ranging
from 1.531 (very low) to 2.348 (moderate). Meanwhile, the evenness level of fi0fai species in YYR\/v' ranges from 0.459 (high) to 0.930 (very high). Based on the results of the biodiversity indices computation, the floral biodiversity in YYRRW is low and evenly distributed. As an ecosystem becomes fess diverse, competition among for a species within the watershed is very low causing high survival rate. Due to similarities in species, results indicate that YYRW is unstable and vulnerable to anthropogenic activities.With this, the conservation of the remaining indigenous floral species, especially those categorized as vulnerable, is needed. A greening program (tree painting) of indigenous flora; species must be proposed and implemented to help revive the fiver watershed. Last\y, a seminar or program on the importance of indigenous flora species must be organized to increase the awareness of the communities within the watershed
