Title: Urbanization and Plant Communities: Comparing Native and Invasive Herbaceous Plants in Selected Disturbed and Undisturbed Sites in Vigan City
Slide 1: Title Slide
- Research Title: Urbanization and Plant Communities: Comparing Native and Invasive Herbaceous Plants in Selected Disturbed and Undisturbed Sites in Vigan City
- Student Researcher: Jimmya Mae Dayag
- Subject: General Ecology
- Location: Vigan City, Ilocos Sur
- Academic Year: 2025–2026
Slide 2: Introduction
Background
- Urbanization alters natural habitats through clearing, soil compaction, and frequent human activity, creating disturbed sites that favor invasive plants over native species.
- Vigan City is a UNESCO Heritage Site undergoing residential/tourism expansion; effect on ground-level herb plants remains understudied
- Native herbs support soil stability, pollinators, and biodiversity; invasive herbs often displace them. This study compares their communities in disturbed vs undisturbed sites.
Research Gap
- Most local studies focus on trees; lack direct comparison of native vs invasive herbaceous plants between disturbed & undisturbed sites in Vigan
Objective
- Compare species composition, richness, and abundance of native and invasive herbs; relate differences to level of site disturbance
Slide 3: Methodology
Study Area: Paired sites in Vigan City — Disturbed (roadside, residential edge, public park) vs Undisturbed (protected grassy slope, riparian zone, green reserve)
Sampling Method: Systematic 1m x 1m quadrat sampling with replicates per site; record abundance, percent cover, and disturbance indicators
Identification: Use Philippine flora references and herbarium standards
Data Analysis: Compute species richness, relative abundance; use t-test to compare diversity between site types
Slide 4: Expected Results
Disturbed Sites: Lower native herb richness/abundance; dominated by aggressive invasive herb species
Undisturbed Sites: Higher native herb diversity and cover; fewer invasive individuals present
Statistical Outcome: Significant difference will confirm that increased urban disturbance reduces native herbaceous plant community quality
Slide 5: Discussion & Application
Interpretation: Urban disturbance weakens native herb survival while giving competitive advantage to invasive species
Significance:
- Provide baseline data for Vigan City environment and tourism offices
- Recommend resilient native herbs for sustainable roadside/community greening
- Guide targeted invasive plant control and biodiversity conservation efforts

This research investigates the impact of urbanization on herbaceous plant communities, focusing on the comparison between native and invasive herbs. Conducted in Vigan, the study employs paired quadrats to assess cover and abundance in disturbed and undisturbed sites. Results indicate that disturbed areas favor invasive species, while undisturbed sites promote native diversity. The findings aim to inform strategies for urban greening and invasive species management.
