This is no ordinary squirrel. It is likely a ground squirrel, since, as such a designation and its presence on the ground suggest, it likely lives in the ground. That divot on the ground in front of it seems to be a burrow, presumably where it lives. It seems to be rather plump for a ground squirrel. Perhaps it could be a common squirrel who lives on or under the ground because it is too plump to live in trees. I have no idea. We did not get any more acquainted than necessary for me to get this picture from a significant and what I considered to be safe distance. Although a squirrel like this could inflict major injuries, I doubt that it can move very fast. It reminds me how fortunate that we do not contend with such large rodents at work. Gophers are small but very destructive to the vegetation within our landscapes. I do not want to know how much damage this squirrel or whatever it is is capable of. It must consume a considerable volume of roots, foliage or whatever it wants to eat. Supposedly, such squirrels, whether in trees or in the ground, are not as destructive as gophers, but I do not know what to believe. I suppose that some wildlife is more obviously worse. Fortunately for us, deer avoid our landscapes, though we could do nothing to exclude them. No one knows why. Much larger herbivorous wildlife that inhabit other regions, such as the Pacific Northwest are more voracious than deer. I can not imagine the extent of damage that just a single moose is capable of. Nor do I know how such wildlife can be excluded from landscapes. It seems to me that a moose can probably go wherever it wants to.
