I suggest that stationary nodes spawn foragable resources in a 100x100 or 250x250 area around the central node.
In this fashion walling off nodes on a mountain would be impossible, walling regular nodes would require autistic amounts of time and labor, throwing up a village claim (on the 250x250 spawns) wouldnt fully cover every potential spawn.
you could still inspect the node to discover when the resource will spawn, you'll just have to search a little bit to find where
im certain this has been suggested before, but throwing it out again for emphasis
