Life, the Universe and Jarrah
Story of the Universe
It took all these things billions of years of breaking up and reassembling before they formed the patterns we recognise and name.
One such organised pattern of things is our planet Earth. The story of Earth had begun. But Earth could not live its rich and beautiful life story without the rest of the universe.
Story of Earth
Story of Jarrah
These expressions of order are called systems,... like the solar system and living systems, or ecosystems.
An ecosystem is a system of soils, plants and animals that live together in communities. Different ecosystems arise because of different soil and weather conditions. Different soil and weather conditions arise because of their positions on the earth. Different positions on the earth arise because of the places where different elementary things assembled. All these arisings happened because earth itself was located in exactly the right place in the solar system for them to happen. Earth was located in the right place because of the way things expanded from the fireball.
Thus, the only place in the universe that could assemble all the things needed to grow into the diverse species that make up the jarrah forest, was the Darling Range.
Darling Range system of soils, weather, plants and animals contribute
an enormous number of genes to earth's supply.
Importance of Jarrah Remnants
Fragments of the original forest remain in isolated patches, usually small, often on farms and roadsides. These remnants are usually neglected, even abused as there has been little appreciation of their importance.
But these remnants often function as refuges for populations of rare plants, or even animals, that are just 'hanging on' in the face of extinction. Here, the gene pool, which is the source of health to a population if it is large and varied, is small; isolation restricts the chance of increase. Roadside remnants may form the critical corridors that link otherwise isolated populations.
Hence scattered remnants of the jarrah forest ecosystem have a significance much greater than their size and nature would indicate. Each remnant harbours and protects a proportion of the rich Biodiversity of the whole. To what degree they do this no-one knows.
Can I live without the diverse species of plants and animals that make up life on Earth?
No. Humans are related to the Earth itself, and to all species of plants and animals. We are also related to the sun, moon and stars. We need their help to live.
And the little patches of jarrah bush, how do they help us to go on living?
To understand that, we need to know about the story of the universe.
