Impacts of Climate Change to Eleocharis Habitat in Tram Chim National Park, Dong Thap province, Vietnam

Abstract

Combining the current remote sensing platform combined and field survey is one of the effective methods to assess the impact of climate change on the distribution of plant cover as well as their structure. This study combined field surveys in April 2019 and image analysis from google earth pro in real-time in May 2006, 2009, 2013 to assess the change of Eleocharis group in Tram Chim national park. The results of the study showed that Eleocharis group, which admirably adapts to the acidic soil conditions (pH <4.5), had significant changes. Although water storage has created an extremely safe environment to avoid the impacts of wildfires, temperature rising at midday made Eleocharis less alive. It could be seen that climate change had affected the physiological characteristics of the tropical grass group, more specifically, made their ecological limits change and narrowed the distribution area of the most developed group in the national park.
