Yes yes that is what they are, I couldn't think of it. OMG some have six inch spikes on them. I cut them all up as high as I could reach, all the way around. They tear my husband up when he mows. I even ripped out a rouge rose bush. Told my DH, that's it, I'm sick of getting tore up, so no more anythings with thorns in our yard. I do love the the trees And only took out those that had real bad ice damage. Now they are pruned up high. Now it will just be maint. To keep the, that way.
