A handful of small trees stand at the edge of a clearing. The wind blows gently as the sun starts to rise in the east. You can almost see the trees reaching for the light, as they slowly convert the sunshine into sugars, which is used to grow and produce seeds. Each species will have different survival strategies, but all trees have a natural urge to disperse their seeds towards the middle of the clearing, where there is less competition and more fertile ground. However, it won't be long until the many saplings have filled the available space and the fight for sunshine will become more and more intense. In the meantime, some trees will have grown old and will die, freeing up precious ground for seeds to settle and hopefully germinate.
