I may have told you before, but my allotment has a lot of plastic sheeting on it to supress weeds. When I pull it back for the robins to feed, there are often tunnels. I always assumed they were rat runs, but now I wonder if they are moles, as there are mole hills on the next door lawn, and they are now appearing in some of the areas I have cleared and covered in wood chip. I thought moles were tiny though, and these seem too big. Does anyone know how big mole tunnels are? Sorry there isn't much in the photo for scale! Thanks
From personal experience (although I'm far from expert!) moles are stocky little things several inches long and make very long tunnels about 5 - 6 cm in diameter. There should be an old post of mine in the mammals section with a photo of a dead mole. This tunnel (if it is a mole) is likely to be a temporary job as it is so close to the surface.
The more I think of it, the surer I am it's moles. It's pretty urban, and damp, and quite close to the river (Taff). I have lots of worms (Robbi is very grateful! ) and there are definitely moles around. Here is another photo with a size 7 1/2 for scale
Hi Teasel, I know this is an old post, but could be a Mole. It will be a solitary Mole, not several, as they live a lone life and will avoid other Moles, except to breed. Moles will tunnel close to the surface if there is limited soil (I've seen photos of one lawn, with very poor soil, where the initial tunnels were plain to see) and also when the depth would be confusing for the initial tunnels as in this case, with the covering over the soil. I love Moles :-) Shamefully they are not protected here, which is dreadful, they do no harm to the environment and just live their lives, which involves tunnelling, and are killed often because people like a nice lawn, and can't be bothered to just sweep up the mounds.They do not purposely pull down or damage vegetables and plants and their roots, damage to them is usually minimal ,they eat worms and beetles etc Also, killing them is futile, as often when one Mole dies, another will take up residence in it's tunnels (I am not saying you would kill it, I'm on about others) I'll do a separate post on Moles:-)
You know a lot about moles I am happy to have them as I am trying to grow wildlife with a few fruit and veg, but don't tell the council I've read that mole nests are quite deep, so I think some are rats as I've come across nests of shredded plastic / veg matter quite close to the surface. I don't mind them either but the shredded plastic is a pain. Oh, and welcome to WABI!
As a slight diversion to thread. I knew a gardener who always collected the earth tossed out by moles as he said it made wonderful sifted and clean earth for potting up his plants so he did not need to buy compost.
