Impact of wildfire on vegetation health at wetland area in Tok Bali, Kelantan

This study investigates the effects of wildfire on vegetation health within the wetland area of Tok Bali, Kelantan, through the application of remote sensing techniques. Vegetation changes were analyzed between the pre-fire and post-fire periods, specifically from 2019 to 2020. The assessment focused on four vegetation classes: (i) non-vegetation, (ii) low vegetation, (iii) moderate vegetation, and (iv) high vegetation. A supervised classification approach was employed, followed by Normalized Difference Vegetation Index (NDVI) analysis, achieving an overall classification accuracy of 78.13%. The findings revealed a notable reduction in moderate and high vegetation classes after the wildfire event, accompanied by an increase in low vegetation coverage. This indicates significant ecological disturbance and suggests early- stage vegetation regeneration in the affected area. The study demonstrates the effectiveness of remote sensing for monitoring vegetation dynamics and highlights the susceptibility of wetland ecosystems to fire-related impacts. These results underscore the need for continuous monitoring and the implementation of proactive land management strategies to enhance the long-term ecological resilience of the Tok Bali wetlands.
