Tomorrow is National Tree Day, and as in previous years, I’ll be getting outside and finding a place for a native seedling or two somewhere in my garden. This year, I’ve earmarked a spot for a Crows Ash, Flindersia australis. This species would have been indigenous to my area when the land was virgin forest, and there are still some fine old specimens around. A beauty can be found in the south-west corner of Peacehaven Botanic Park at Highfields, where Tree Day celebrations will be held tomorrow morning. As a complement I’ll also be planting a couple of fruit trees.
It might comes as a surprise, considering the lack of publicity such an important initiative receives, to hear that National Tree Day has been an annual event for the last 15 years. It was co-founded in 1996 by Olivia Newton-John and the environmental organisation Planet Ark, and to date, is responsible for planting more than 15 million native trees. Another one million or so will go in the ground tomorrow.
Some of the benefits of planting trees are obvious. At the most basic level, they create shade, helping to cool us down. You think this would be so simple that it’s elementary, but drive through some of the new estates in Toowoomba or Highfields and you’ll enter a surreal landscape almost totally devoid of any trees. Why run the air conditioner all day to cool yourself down in summer when a well located tree can do the job for free? You’re welcome to live where you like, but lest we end up inadvertently creating suburban deserts, I think it would be wise to plant more trees.
Maybe you’re of the opinion that you prefer your air conditioner, and all this tree planting caper is a bit of a lark. Let me try to convince you otherwise by pointing to the example of Kenya’s Green Belt Movement (GBM) and its inspiring founder, environmental and political activist Professor Wangari Maathai. Since 1977, GBM has planted more than 45 million trees in sub-Saharan Africa, established 6,000 village nurseries, and trained more than 30,000 poor rural women in skills such as horticulture, forestry, food processing, and bee-keeping.
The net result of such activity is that desertification in north east Kenya has been halted by GBM’s planting of long “green belts” in what was an eroded and deforested landscape. With reforestation comes increased biodiversity and restored ecosystems, as well as fewer crop failures and water shortages. Wangari Maathai received the 2004 Nobel Peace Prize for her efforts. Her work is based on the belief that a healthy natural environment is at the heart of an equitable and peaceful society.
Contrast what’s happening in Kenya with the situation occurring in Niger, north-west Africa. Here, rampant desertification has encroached on what little arable land the already dry country possessed, leaving more than 80% of the landscape covered by desert and causing major food insecurity. Some reforestation efforts have been undertaken in recent years, but it hasn’t been enough. Now facing a prolonged drought, it is estimated that half of Niger’s population of 15 million is suffering form severe malnutrition. More than three million are classified as starving. Kids, as always, are being hit the hardest.
What’s the link between starving children in west Africa and a festive day of planting in the comparatively fertile Darling Downs in Australia. It’s the importance of trees. Once and for all we need to clear up the misconception that trees are little more than obstacles and inconveniences standing in the way of development. Let’s get real. Trees are vital. They provide habitat – for ourselves and for native animals – they help maintain healthy rural landscapes, they feed us, and we ought to never underestimate the role they play in enhancing our collective quality of life. Trees deserve far more respect than we currently afford them.
I’ll leave the last word to Wangari Maathai:
“I love the trees, I love the colour. To me they represent life, and they represent hope. I think it is the green colour. I tell people I think heaven is green.”

Add to all these fabulous benefits the recent discovery that rainforest trees actually seed rain in the sub-tropics and tropics. What more excuse do we need to plant a beautiful tree, like a Blue Quandong, for example.
Thanks for th great article.
