I get annoyed when 'bushwalkers' do things that deliberate damage the natural environment, I get angry when they are from a bushwalking club and should know better, and I get furious when they show no remorse for their actions (that are not only unethical, but illegal!)
So here's the story. Over the weekend members of the UWS Bushwalking Society committed an act of vandalism in a National Park while part of an organised club walk. It occurred on Sunday 23 June on a walk to Pindar Cave in Brisbane Water National Park, NSW.
During the walk, a UWS student has scrawled the following graffiti on a rock face: "UWS Bushwalking Society 2013". He then shared the photo on the club's facebook page.
I saw this and left a note in their facebook group highlighting the inappropriateness of any graffiti in a national park and also shared with them a copy of the Bushwalkers Code of Ethics. I assumed that would be enough to allow them to realise the actions were inapropriate and to appologise. Instead I received the following response from the man who organised the walk this incident occurred on:
Hi Tim- with respect- I see no need to apologise nor do I find it unacceptable behaviour in this instance. Firstly, I would like to stress that we do take the principle of environmental awareness very seriously- when we did this walk we took care to pick up any rubbish we encountered which other thoughtless walkers left behind. Secondly, the inscription was made with charcoal from burnt out and legal fires at the site. If you would like to make the argument that charcoal graffiti is environmentally destructive I would be interested to hear it. It is a natural substance which will leave a non-permanent mark and with the next rainfall no doubt it will be erased. From the perspective of aesthetics, I generally agree with you that graffiti is wrong but I would also point out that our graffiti was not offensive in any sense of the term. If you have done the walk before you would have noted that our markings on the wall are hardly unique- the cave is littered with them. This is not to suggest that whatever is popular is right but given the reasons above I do not feel in this case that our markings were egregiously inappropriate. I share your concerns about respecting nature and I understand your outrage at the thought of nature being defiled permanently. However I assure you that this was not the case in this instance.
This left me absolutely fuming. What kind of f***tard thinks it is acceptable to deface a wilderness area? And what kind of bushwalking club has leaders (this guy is their most active trip leader) who are promoting this kind of action!!!

I got so hot under the collar that I've contacted the University, NOWS, the local police graffiti squad and Bushwalking NSW.
Am I overreacting here? Does anyone else know of bushwalking clubs / individual bushwalkers who think it is acceptable behaviour?
