Photo by mattiasklumofficial | Morning in the Danum Valley, on Malaysian Borneo. This rainforest is estimated to be at least 130 million years old, making it one of the oldest in the world (twice as old as the Amazon rainforest). Extremely rich in biodiversity, Borneo provides habitat for about 15,000 known species of flowering plants, more than 3,000 tree species, 221 terrestrial mammal species, and 420 bird species. After years of work in Borneo, it's one of the places in the world deeply embedded in my heart!
