Two years ago Lucy was saved from a rural area in New South Wales, Australia. Today, she is one of the lucky animals living in rows of trees that have been created to protect koalas and other animals by saving their smaller and smaller habitat(栖息地) , or natural environment. 

The trees, planted by the local protection group Bangalow Koalas, are made up of large systems of plants. They are a lifeline for koalas and other animals. All of them are in danger of dying out, or at risk of extinction. The trees provide a safe way across the koala's increasingly broken habitat. This protects koalas from human threats( 威 胁 ) "Our trees are actually trying to get them away from humans, cars and dogs. "said Linda Sparrow. President of Bangalow Koalas.

The koala is expected to die out in the wild in New South Wales by 2050. Some of the biggest threats include wildfires and habitat loss through land clearing for development. 

Bangalow Koalas has planted over 336, 000 trees on 119 areas, helping koala protection and improving the local ecosystem(生态系统) . The group. which depends on community volunteers. aims to plant 500, 000 trees by 2025. "The neighbor would want to join and then another neighbor would want to join. "Sparrow said. Volunteer Lindy Stacker. who has been planting trees for over five years.

A recent report by the Australian Koala Foundation said the animal was worth about S3. 2 billion per year to the tourism industry. However. the World Wildlife Fund-Australia reported a drop in koala populations in Australian states. "I can't imagine a world where there's no koalas in the wild. " Sparrow said. "We're going to do our best to make sure that doesn't happen."
