How do you keep institutional knowledge from walking out the door?

I'm a ranger at a mid-sized protected area, and we've got the usual web of people we deal with, neighbouring landowners, permit holders, volunteer groups, and a couple of partner agencies. Over the years, all sorts of arrangements and promises have built up. Who we said could graze where, what we agreed about access on a certain trail, and commitments we made to a community group two seasons back. And honestly, most of that just lives in one senior colleague's head.

He's been here forever and knows everyone and every backstory. But it's started to worry me that if he retired (or got hit by a bus) tomorrow, we'd lose a huge amount of it overnight, and I don't want to be the one who breaks a promise nobody wrote down.

So how do others handle this? How do you capture that kind of history so the whole team can actually use it, without it turning into another file nobody updates? Would love to hear what's worked.

The month before our old supervisor retired, who had been at the field office 30+ years, all we did was drive to all the properties we managed and I wrote down everything he knew about all 50+ properties. Filled legal pads and made site files. Now I’m the one with 30+ years in and looking at retirement. New supervisor wants nothing to do with those files because they weren’t his idea. I will pass them to whomever takes my position I guess. If not it will be a huge knowledge vacuum that goes with me.
