A Comparative Study of Tree Species Responses to Enrichment CO2 Over A Six-Year Period in Tekam Forest Reserve, Jerantut, Pahang

Abstract

Industrialization has increased greenhouse gases, particularly CO₂, due to urbanization, agriculture, and industrial processes which leads to climate change. Climate change affects on Malaysian forests including physiological processes, forest distribution, and biodiversity, as these are influenced by air temperature, moisture, CO₂levels, and soil nutrients. A free-air carbon dioxide enrichment (FACE) system serves experimental platforms to explain plant responses to escalating CO₂ concentration, offering the most realistic conditions for stimulating the effects of anticipated enrichment CO₂levels. The purpose of this study is to assess and compare the response of tree species and quantify tree community structure under enrichment CO₂ in the FACE plot over a six-year period in Tekam Forest Reserve, Jerantut, Pahang.
