hugelkultur impact on gophers

I"m putting in a hugelbeet in one of my raised beds.  To make my raised bed originally I laid down weed cloth and used cinder blocks to create the border, and filled.  This has worked well for me, but require a great deal of water.  I have removed the soil, ect. setting it aside to reuse.  Removed the weed cloth, and I find a gopher hole straight under my bed.  My plan was to dig 3 feet down fill with wood, dirt, small wood, and or chips, compost, and the soil I removed plus compost and other stuff I like to refresh my bed with before I plant a new crop.  Now I'm not sure what to do.  I did this to another bed last fall and it's been fine, but I planted garlic and onions in it, so it probably isn't enticing to gophers.  I am without a job right now so I can't spend any money on this project.  I have 1 roll of chicken wire, and a good amount of weed cloth.  I don't want to use up the chicken wire, I know I'm going to need it.  I really don't want to use the weed cloth, most of the reason I'm changing to this type of system is to encourage worms and natural organisms to help the health of my soil.  I also don't want to do all this work and loose everything to gophers.  Does anyone know if the wood will deter or entice the gophers?  Do I need to line the hole with chicken wire?  Then I have to consider what the wire is leeching into the soil.  (I know some of you are saying I have to worry about what the cinder block leeches into the soil.  I did my beds years ago, never even giving that kind of thing a thought.  Now it's what I have and have to go with it.)  What if I  dig the hole larger then I need and line the bottom with wood like I planned, but also lined the whole outer perimeter with wood and branches making a wood barrier.  I know it will brake down, but it would take a few years.  I'm open to suggestions, and look forward to your insight. Thanks.  

The wood should deter the gophers, at least until its much more decomposed. I would skip the weed cloth and chicken wire and just rely on the fact that they should experience the buried wood as a barrier they can't dig through.
We never had problems with gophers in our small hugels even though they did some damage to the crops planted between them (including garlic, once they discovered it we were never able to grow a crop again in that yard).

I've had some success using Sepp Holzer's suggestion of burying a layer of well dried blackberry canes in a layer at the bottom of the hugel.

I don't have many black berry vines, but I have 30+ rose bushes organically grown.  That could work thanks.  I guess I have been lucky, or they haven't found there way through the wood.  I know all creatures have a place, but man I hate gophers!

It's almost done, so time will tell.  I dug a hole.  I thought wow this is a huge hole, it's got to be 2 2 1/2 feet, then I measure it and its 16"  what a let down.  I decided to go to 18".  It looked deep enough to do what I wanted to do, and make the bed 24" with the height of the cinder blocks.  I filled the bottom with wood built a kind of wooden fence out of small branches around the perimeter. ( loved the idea of rose wood, but don't have any at the moment, and if I trim it now it's all soft, so I decided not to use it.) Filled the nooks, crannied and topped with native soil, then a layer of small wood and branches, spread bagged organic chicken manure that had gotten damp and started to smell, topped that off with soil, put a layer of 3 year old wood chips, and a layer of soil.  Now I am at normal ground level. I will use a combination of organic soil, organic compost, mushroom compost and organic chicken manure.  This will be the bulk.  I will also add some other things I have at hand like rock dust, vermiculite, maybe a bit of bone meal, and blood meal, maybe some organic fertilizer.  As I plant I will add worm castings, since I don't have a lot of that and I want to make it count.  If the weather will let me I will finish the top today and then the fun begins of planting.  Time will tell if I have done enough to keep those nasty gophers away.
