Barbed wire

Our lovely walk around the fishing lake which I have previously blipped now has a barbed wire fence separating us from the lake and another one separating the path from the undergrowth. Apparently the owner of the land wants to stop otters getting in the lake and eating the fish and also doesn't want to be liable if people go into the water. I appreciate it is private land and so the owner can do what they want but a lovely nature walk (public right of way) where I could photograph butterflies and dragonflies is spoiled. The fence is shoulder height.
