My friends and I do wildlife research around the Nam Tok Chet Si waterfall north of Chiang Mai, a beautiful place in the forest with many animals enjoying the spray from the waterfall which keeps them (and us) wet and cool.
Once we've cooled off we venture into the water and look for wildlife. Our task is to monitor changes in health and population sizes. We use waterproof cameras for photos and phone apps to log our observations.
He coordinates our research, picks the wetland areas we go into, and what species to focus on. Once he has defined our objectives, he sends us into the water for explore the area. Then he visits each of us in turn to help and assist, goes in and out of the water more than often than any of us. Most of the day he is dripping wet.
