Today is National Tree Day. Combined with Schools Tree Day it is Australia’s biggest community tree-planting and nature care event. Co-ordinated by Planet Ark, these are special days for all Australians to help out by planting and caring for native trees and shrubs to improve the environment in which we live. National Tree Day started in 1996 and since then more than 2.8 million people have planted almost 20 million seedlings! It is held on the last weekend of July every year – this is the optimal planting time for the majority of Australians towns. However this might not suit certain areas, so you can find a date that suits you. As Planet Ark says, “every day is Tree Day”.
The organisers put great store in local provenance. This term describes native plant populations that naturally occur in a given area. Many native plant species can be found to occur across a broad geographic area or range. For example, hairpin banksia (Banksia spinulosa) naturally occurs across 3 states, from coastal Victoria to Cairns. However, the plants growing in a specific area have adapted to the local conditions over a long period of time. Although of the same species, a hairpin Banksia from southern Victoria will have a different genetic makeup to it’s cousin in Cairns, just as the same species of plant found on the coast will be different from that growing in the mountains. Different populations containing local genetic variations are called provenances. For true local provenance, the individual plant is grown from seed stock from parent plants within the same population (or as close by as possible). Preserving local provenance populations is an important way of protecting biodiversity. For more information visit the Benefits of Local Natives page.
“I grew up out in the bush and everyone living and working in regional Australia knows how important trees are to the land. National Tree Day is all about individuals, communities and the country coming together to plant trees and to make a big and positive impact for our great nation and future generations,” Lee says.
This year the campaign aims to reach the milestone of planting its 20-millionth seedling. Everyone can help by getting involved in one of the hundreds of organised community events, or just planting an indigenous tree in your own garden. Every tree makes a difference!
