Hello, everyone. This is Enta. When I go out to survey slopes, I pay special attention to the bamboo. Well, it’s not just the bamboo—but by looking at the plants growing there, I can get a rough idea of the soil conditions. “Bamboo groves = a sign of good surface water retention,” “willows and alders = a sign of valley bottoms or high groundwater levels…”
