True, but I was referring to copses of trees, creeks, hillsides, slabs of boulder, underground water. Things that are a pain in the ass to farm around so often affect the division of property lines and then the selling rates of land.
That happens in parts of the US that actually have those things, just not in the super flat bits that donβt have anything interesting in them to use as a boundary to begin with. Kinda hard to break things up by rivers or ridges or trees when there arenβt any there naturally. But near me, that stuff is super common as boundaries for fields for exactly the same reason.
Fun fact: the trees used to mark those boundaries are called witness trees, and since they were never chopped down they are the only remaining old growth trees in a lot of areas.
