We live by the South Umpqua River and our garden and lawns are well-irrigated. Consequently, we are forever fighting Townsend's pocket gopher. We have tried trapping them and poisoning them but never seem to make much headway. As the proverbial saying goes, you beat them down in one place and their mound pops right back up in another area. Can you please recommend a particular poison that has been tested to be most effective. Thanks, Sherrie Wieland

Are you sure these are not Moles? I say that because of the shape and distribution of mounds, but I do not deal with moles in central Oregon, so I could be wrong.. I am more familiar with the Northern Pocket gopher in central Oregon. I do not see the typical horse shoe shaped mound. The Townsend pocket gopher is in one little area Northern CA, and then in (Harney and Malheur counties) Eastern OR, and Southern ID. Check out "The Handbook: How to Control Wildlife Damage" from Nebraska. It is a great resource on moles, ground squirrels, and pocket gophers (and other critters and birds) with descriptions, solutions, and ranges of where they live. https://digitalcommons.unl.edu/icwdmhandbook/
Please check out this link to see what the range of the Townsend pocket gopher is. https://www.iucnredlist.org/species/42598/115193369
There are many types of traps that can work very well.
From the picture it would appear that you are over grazing your pasture. You really want to leave 3-4 inches of plant height and not graze off all of the top growth.

I was hoping for a reply from our local Douglas County Oregon extension agent, as our conditions in Western Oregon are different than Central Oregon. I did make a mistake, it is a Townsend mole we are having trouble with, not a Townsend gopher - sorry.
