A shared memory for the patches people tend
A patch is a piece of ground somebody looks after. Tendium gives it one record — every observation anyone has made there, and the answer each one got — so a place stops depending on one person's memory.
Running in Oak Bay, British Columbia. No account needed to add to a record.

Volunteer-led restoration runs on one leader's memory, a chat thread and a binder. When the leader burns out, the site's history goes with them — and the neighbour who walks past it every day has no way in that doesn't mean joining a committee.
Print it, tie it to a stake or a gate. Scanning it opens this patch — what it is, what has been happening, and one thing that could be done.
A photograph, a typed line, or a spoken note. No account, no sign-up, no dropdowns to fill in. Being structured is the record's job.
An identification with its confidence, grounded in this patch's own record — including what that same plant was doing the last time somebody looked. Both halves stay.
For whoever keeps the place
One queue holding only what is actually waiting on you. The record beside the things it keeps returning to. Work you wrote down, the people you can reach, and the two pages a stranger sees.

Midland Miyawaki Forest has thirty-seven observations on it, and all of them are somebody's.
