I put ½" metal fabric under my two raised bed 'sleeves' as well, as we get gophers AND moles on our rural Central TX property. Grrrrr. The gophers are a much worse problem for us. they were well estsablished on tshe 42 acres when we bought it. I don't feel bad, as the adjacent properties on the Google map look more dotted with gopher mounds than even on ours is........for miles and miles actually.
Moles only eat bugs, worms, slugs, snails and insects. It is their burrowing/digging that tears up plant roots that get in their way on their seach for bugs. Luckily, we don't see many sign of moles, maybe one tunnel a year? So I figure the metal mesh will spare the most of my garden veggie roots from our gophers. These are new raised beds as I'm new to veggie gardening. I'm just now setting up my soil/compost in them for planting next spring, so I haven't learned if the metal mesh will be effective at saving their roots or not. Hope so.
