More than 5000 trees are being planted by 24 landowners through a post-fire koala habitat recovery grant funded by Landcare Australia and guided by Hastings Landcare.

The project aims to create additional habitat and food resources to support koala populations, trees have been donated by the Port Macquarie Koala Hospital.

Lorne residents Taliska and Dale Arentsen deep stem planted 200 trees on their property and installed electric fencing against feral deer as part of the program.

"The project was a great way to continue the work we are undertaking to rehabilitate our property including the riparian zones of Camden Haven River which borders our 40 acres," Mrs Arentsen said.

"It was also special to plant them when we did as I was 38 weeks pregnant with our daughter. We will watch these trees grow with her.

"The whole family pitched in and it was a really rewarding group effort. Our two-year-old son was also actively involved and can't wait for the koalas to move in."

Mrs Arentsen said the trees have thrived with recent rain, despite some of them going under in flood water.

Hastings Landcare president Peter Fitzroy said the program is supporting local people caring for the environment, farmland and natural resources of the region.

"This project provides benefits for our koala populations both now and in the future, and supports sustainable land management practices," he said.

Mr Fitzroy said members of the public seeking to support or join the program can contact Hastings Landcare on 02 6586 4465 or office@hastingslandcare.org.au.
