Trees are on the job 24 hours a day. Every day. They help clean the air we breathe; filter the water we drink and provide habitat to over 80% of the world’s land based biodiversity.

Healthy, strong trees act as carbon sinks. Through their leaves and bark they sweep up particles like dust and smoke and absorb harmful pollutants to release clean oxygen for us to breathe.

Their intricate root systems act like filters, removing pollutants and slowing down the water’s absorption into the soil. This process prevents waterslide erosion and reduces the risk of over-saturation and flooding.

A single tree can be home to hundreds of species of insects, fungi, moss, mammals, and plants. Without trees, birds and possums would have nowhere to call home. Their canopies create wildlife corridors for animals, birds, and insects - connect them to seasonal food sources that are away from predators. 

Trees provide shade and reduce the heat urban island effect. Unlike hard surfaces that absorb the sun’s heat, trees reflect heat and actively cool the air.

Insightful are the words of Isobel Bowden (1908-1986) when she said, ‘We can’t afford to lose another tree’. Born in Woodford and awarded an OAM for services to conservation and botany in the Blue Mountains, Isobel saw at a local level, the unfolding impact of tree loss on planetary health.

Every tree counts.
