How are these produced? I assume they're not actually digging a giant trench and taking a section, but are the drawings based on measurements of a specific individual in some way?

In any case, very cool to have such a collection.

Really neat. I've often wondered about what the unexposed part of trees and plants are.

Like: am I walking on them? Are they tapping down somewhere deep or are they shallow.

The examples on a hill were interesting; I would have thought the extent would be skewed but it was fairly even

They usually are. It’s a process akin to archaeology where they have to carefully wash away the dirt from the root system, measuring as they go. The problem with this method is that it's hard to reconstruct the entire 3d structure of bigger plants like trees so a lot of the root drawings on the site don’t accurately show how deep they go. It’s much easier with small plants where the researcher can control the soil used.

Modern methods like xray CT or ground penetrating radar can do it nondestructively in the field but they’re usually expensive to set up compared to just sending some grad students to dig.
