|Even when the marking tape is in the tree, it is basically rubbish. Unless someone comes and collects it all up once the path is established enough to follow, which I am unaware of anyone doing, it is abandoned plastic in the environment. I haven't been up to Muline, but say take the track over to Vandieman's, it is a clear foot pad with overgrowth from the sides. No vegetation needs to be removed, just trimmed. This isn't really damaging the regrowth - the bush with it's root stabilising the soil is still there. the formation of new paths around patches that are grown over forms new foot pads, damages new regrowth and feeds erosion. Even if you mark out a path, if it involves bashing through bushes, people will go around via any easier break in the vegetation either on purpose or because they get lost between markers. Some sort of trimming is pretty much always necessary to establish a path and is the lesser of two evils. Have a look at the amount of "trimming" that Parks do to establish paths.
