Yeah. Here in the orchard the Gopher Palaces (I call them) are found wherever I backhoe out the stump of a tree that died. They must feel safe there because the discing never went over that spot when there was a tree on it.
It's normal to find up to a cubic foot of soft fine grasses in these cavities. I figure they must be birthing nests. And as I pursue roots outward from the stump it is obvious that major tunnels converge on these cavities. I dig up and disrupt an area at least the volume of a card table, in hopes they will move their headquarters somewhere away from the new tree I plant at that location.
There's nothing more discouraging than going out to water a new tree and see it fall over, rootless, as its basin fills with water. Second only to that, is when I fill a new-tree basin and suddenly the pool disappears down a gopher hole like I pulled the plug from a bathtub ... then I stomp on the gopher run to seal it, ... and sink into the muddy water, clear over the top of of the knee-high milking boots that I wear when watering. Seems they rebuilt their convention center cave right under the new tree. Bah. :irked:
I've told this story before - the gophers here are so bad that plant geneticist Luther Burbank gave up his experimental plots here and moved elsewhere.
He donated his land to the adjacent cemetery.
