Photosynthesis - the capturing of sunlight energy is the driver of our lives.
It is estimated that vascular plants (grasses, trees, ferns) evolved and started to occupy earth 423 million years ago.
These were the first plants that had the ability to grow tall (unlike the bacteria, algae, moss and cyanobacteria that first evolved).
This ability to grow tall was the start of earth's ability to photosynthesise at levels not seen before - creating growth and the food source eventually for dinosaurs.
MORE IN OPINION:
For 423 million years, our plants have used this energy (growth) and slowly evolved and worked out how to best survive the environmental extremes.
They have worked out how to work with soil biology and other plants.
In courses I'm running, I joke that "Mother Earth doesn't do nudist beaches".
By this I mean that whenever soil is exposed, Mother Earth will grow something to cover herself up.
Think of the soil surface similar to your living skin, when we cut or graze our skin, we form a scab to cover up and heal ourselves.
For Mother Earth, pioneer species are the scabs sent to heal the wound.
The fortunate thing for us as land managers, is that nature wants to grow.
Nature wants to have diversity and cover.
Nature wants to restore ecosystem function.
Our challenge is to work out how we work with our ecosystem to have both ecosystem function and profitability.
How can we profitably create a habitat for desirable plants and biology to exist?
All living beings have the same basic needs: food, shelter, air and water.
So, if we want to improve ecosystem function, the question becomes how do we provide the conditions where the basic needs of our plants and biology are available?
Build it, and they will come. When the conditions are right we see the dung beetles, the wildflowers in the desert, the better grasses come back.
Similarly, when the conditions are right we see the weeds and pioneer species dominate.
Let us be thankful that nature wants to grow and have diversity.
Forever modest and giving, Mother Earth keeps forgiving our mistakes and misjudgements and continuously works to repair ecosystem function for us.
Are you working with or fighting against her in your operation?
Fighting against a system that has been refining its battle plan for 423 million years may not create the outcome you desire?
