That's a good way to look at it. In the modern world we use a few quiet tools. Tiny camera traps sit in the underbrush and only flash when something moves. Drones fly low with infrared sensors to map heat patterns without touching anything. Acoustic recorders listen for changes in bird songs or insect buzzes. And the newest trick is environmental DNA—collect a drop of soil or water, and we can see which species are around just from the traces they leave. All of it keeps the forest untouched while still giving us a clear picture of what's happening.
