One of the most amazing things about working in a tropical forest is the ever-present thrill of what I might encounter next. On our last field trip, myself and our six research assistants woke up just before dawn to the unmistakable, deep resonating growl of a tiger, less than 200m from our tents. It was a little unnerving as it seemed to be circling us, but we knew it was just letting us know that we were in its territory. As the week of field surveys went on, we heard the tiger a number of times and saw many fresh tiger prints, but did not see it directly. However, it was captured it on a camera trap and now know that it is a new adult female for the site. With a global Sumatran Tiger population of less than 700, it’s excellent to know Harapan Rainforest is providing an important protected area for its conservation.
