This week the show comes from Vietnam. I make a botched attempt of singing a line from Noel Coward, and then explore Ba Be National Park in northern Vietnam. Ba Be is an area of deep green rainforest and high limestone peaks. I talk with the director of the park and some of the villagers in the area. In the second half of the show I talk with Chris Shepherd of TRAFFIC about the illegal wildlife trade in Vietnam. Here is this week’s Understorey.
