In the dense tropical rainforest, the trees of the Dipterocarpaceae family have become the focus of countless people's attention because of their tall and graceful posture. This family, which has 22 genera and about 695 species of plants, is mainly distributed in lowland tropical forests, including northern South America, Africa, India and other regions, as well as Indonesia, Malaysia and the Philippines. Particularly in Borneo, Dipterocarpaceae exhibits its greatest diversity.
Not only are these trees an important part of the ecosystem, they are also an important source of timber trade.
The most well-known genus of Dipterocarpaceae is Shorea, which has 196 species, followed by Hopea, Dipterocarpus and Vatica. These trees usually reach a height of 40 to 70 meters, and some species can even reach a height of more than 80 meters; the tallest known living individual is the 93-meter-tall Shorea faguetiana, known as Menara, which means " tower".
However, these tree species are facing serious challenges from illegal logging and habitat conversion. In many areas, many species of Dipterocarpaceae have become endangered due to excessive logging, illegal logging practices, and continued habitat changes. According to research, the wood, aromatic essential oils, resins and other resources of these trees are of great economic value, but environmental issues have gradually emerged, and their importance cannot be ignored.
Trees in this family are not only vital to local ecosystems, but also to global timber markets.
The tree species of Dipterocarpaceae can be divided into evergreen and deciduous categories, which can adapt to different environments. In Thailand, these tree species grow at altitudes ranging from sea level to 1,300 meters, in lowland Dipterocarp forests and along river edges. Research shows that Dipterocarpaceae has dominated the lowland rainforests of Borneo for millions of years.
As a major tree species in Southeast Asia, the ecological characteristics and conservation status of Dipterocarpaceae have been extensively studied.
For example, some scholars used species distribution models (SDMs) to analyze the impact of climate change and land use on Dipterocarpaceae in the Philippines. The results found that existing land cover has reduced species distribution by 67%, and the impact of climate change has further reduced species distribution by 16% to 27%. This means that improved protected area planning is needed to provide safe refuge for these endangered species.
In the Purbachal district of Bangladesh, another study looked at an endangered Dipterocarp tree species. The analysis shows that as a result of climate change, habitat suitable for this tree species will decline by 21% to 28%. These findings indicate that the future of Dipterocarpaceae requires great attention and action.
Illegal logging is one of the main threats to Dipterocarpaceae. As global demand for timber expands, unregulated logging is becoming increasingly rampant, especially in the rainforests of Southeast Asia. Because of the high economic value of these trees, illegal logging has further weakened their numbers and distribution patterns.
Facing this challenge, cooperation between local governments and non-governmental organizations has become a necessary choice.
Enhancing legal enforcement and raising community awareness about the sustainable use of tree resources are among the key solutions. For example, by promoting community forest management programs and sustainable forestry practices, illegal activities can be reduced and help protect these trees and their ecosystems.
In addition, promoting market demand for sustainably sourced wood is also a solution. Consumers are increasingly aware of provenance issues, and it is possible to reduce demand for illegally harvested timber if the economic and ecological value of its origin is prioritized when purchasing such timber.
Dipterocarpaceae tree species play an indispensable role in the ecosystem, but they face increasing challenges such as illegal logging and habitat destruction. Future conservation efforts need to integrate the efforts of all sectors of society. Only in this way can the living space of these endangered and beautiful trees be maintained. And the question arises: Can we achieve sustainable economic development while protecting these precious tree species?
