THE discovery of metal spikes along a walking track has prompted authorities to issue a warning.
The spikes were found on a narrow trail in the Avon-Mount Hendrick Scenic Reserve, north-west of Boisdale.
They have been removed, but Macalister District Forest Fire Management staff warn those visiting the area to be alert, in case there are more.
The spikes pose a risk for walkers and other trail uses, and they also pose a significant danger to wildlife.
Gippsland assistant chief fire officer Chris Stephenson said Forest Fire Management compliance staff have been out and about in Wellington's forests and parks during the holidays patrolling campsites and other areas.
"It's a shame that a minority often spoil it for others," he said.
"Our authorised officers try to get to as many sites as possible, but Gippsland has over three million hectares of public land, so it's impossible to be everywhere.
"That's why we ask the public for help to watch out for and report suspicious and illegal behaviour in our parks and forests, so we can work together to try and reduce the risk to all of us.
"That's why we're saying 'If you see something, say something' to encourage everyone to help us catch and punish the minority who let us all down."
Mr Stephenson said that officers had seen some disappointing behaviour, including finding unattended campfires and an appalling amount of rubbish left at popular campsites.
"We find it hard to believe that this sort of irresponsible behaviour continues year after year, putting the community and the environment at risk," he said.
Mr Stephenson encouraged public help to combat illegal activities such as rubbish dumping, unattended campfires, damage to campsites and facilities, illegal tree felling and irresponsible driving or riding.
Mr Stephenson urged people to come forward with information and photos, if was safe to take them.
He said information would be treated confidentially, and would assist with follow-up investigations and with planning targeted patrols.
