Anatomy of a monitored tree
Every instrument we have at one stand, drawn on the tree it measures. The trunk in the middle is the width the dendrometer is reporting at the cursor - press play and watch it drink.

Layers
Cores are joined to this tree by LOCALITY, not by site code: the survey numbers one code per locality and the register numbers two.

Legend
- Why the trunk moves
- A stem is thinner at the end of a warm day than it was at dawn, and swells again overnight.
- Only the dashed line is growth
- The running maximum never falls. Everything below it is water the stem has given up, not wood it has lost.
- Two plots, one locality
- Each site is a pair - a reference stand and a drier one - so a season can be read as a difference rather than a number.
- Rain from the nearest MET station
- What fell over there. Soil water above is what actually reached these roots, and the two are not the same quantity.
