"We all enjoy a nice fire when it gets cold, but it is important that you source your wood legally," South East Local Land Services Yass and Boorowa area local manager Chris Harris said.

Anyone caught removing timber or disturbing vegetation (alive or dead) from a TSR can be fined up to $5,500 under the Local Land Services Act 2013.

These rules help protect the integrity of the network of Travelling Stock Reserves which is recognised as an asset of state significance with agricultural, social, cultural and ecological values.

"We've been getting reports of illegal collecting around Boorowa and Yass, we'll be monitoring these areas continuously," Mr Harris said.

"We need to make sure there is a clear understanding in the community about the importance of TSRs and their long-term viability."

TSRs are an extremely important refuge for many rare and endangered native plants and fallen logs and standing dead wood can be part of their habitat.

Decaying timber and leaf litter are also important in the process of nutrient recycling back into the soil.

Members of the public are asked to report any illegal activity to Local Land Services on 1300 795 299, or to contact NSW Police on 131 444.

Taking note of registration numbers, descriptions, locations and dates also provides valuable information that can assist in the prosecution of offenders.

Travelling Stock Reserves are clearly signposted, but if you are unsure of the status of a piece of land, please contact the Yass Local Land Services office on 1300 795 299.

Members of the public can apply for a permit to collect firewood from selected state forests. Contact 1300 655 687 for details or visit www.forestrycorporation.com.au for further details.
