I’d start by letting the trees do the work—plant the sensors in bark, weave them into vines, so they’re almost invisible. Then I’d lock the data with a natural encryption—maybe use the rhythm of the wind to scramble the signal, only readable by the same pattern. I’d keep a silent watch over the edges, moving from shadow to shadow, and if anyone tries to pry, the sensors will heal themselves and drop a warning flare that looks like a startled owl. Trust is a luxury, so I’d only let a few of my own boots touch the network.
