The value of trees cannot be understated. They filter air, sequester carbon, provide oxygen, conserve oil and water, prevent desertification, and protect and stabilise ground cover. In Australia, native trees assist in making our agricultural areas more sustainable – preventing salinity and soil erosion, and providing shade, shelter, food, and habitat to native animals. Trees also have a vital role in addressing climate change. As they grow, they uptake carbon dioxide from the atmosphere, using the energy to grow their trunks, stems, leaves, and roots.
