Paysage de forêt tropicale au pied du mont Tangkoko et Duasudara (Dua Saudara) dans le nord de Sulawesi, Indonésie. Selon un nouveau rapport de la Wildlife conservation Society, on estime que les forêts tropicales de haute intégrité éliminent et stockent environ 3,6 milliards de tonnes de CO2 par an (net) de l’atmosphère. Cependant, la forêt – et les espèces sauvages qui la soutiennent – sont menacées. « Entre 2012 et 2020, les températures ont augmenté jusqu’à 0,2 degrés Celsius par an dans la forêt, et l’abondance globale des fruits a diminué de 1 pour cent par an », a écrit une équipe de scientifiques dirigée par Marine Joly.

Landscape of a rainforest area at the foot of Mount Tangkoko and Duasudara (Dua Saudara) in Bitung, North Sulawesi, Indonesia. A report by a team of scientists led by Marine Joly, in relation with crested macaque (Macaca nigra) conservation, has revealed that the temperature warming is threatening Tangkoko forest. "Between 2012 and 2020, temperatures increased by up to 0.2 degree Celsius per year in the forest, and the overall fruit abundance decreased by 1 percent per year, ” they wrote on International Journal of Primatology._According to a new, different report by Wildlife Conservation Society, high-integrity tropical forests are estimated to remove and store around 3.6 billion tons of CO2 per year (net) from the atmosphere. However, to protect them, the stakeholders must save the large frugivores._Large-bodied wildlife species, in particularly fruit eaters such as primates, hornbills, and others—disperse large seeds from tree species with high carbon stock capacity, according to the scientists. In other words, losing these species will change the composition of forests: wind-dispersed or small-seeded tree species with lower wood density, and therefore lower amounts of carbon, become more prevalent._"Many tropical forests have been described as 'empty' owing to loss of animals, often as a result of unsustainable subsistence or market hunting. Such hunting is known to have detrimental effects on target species, broader biodiversity, and the livelihoods and well-being of local communities. Less appreciated is the adverse impact of defaunation on the capacity of tropical forests to sequester and store carbon, which has implications for climate change, " said the lead author, Dr. Elizabeth Bennett, as quoted by ScienceDaily.
