J. Gaps in the Rainforest
Rainforests are dynamic landscapes which are in a constant state of change. Trees grow, mature and fall, and are replaced by new trees whilst the old decay back into the soil to provide nutrients for the new growth. In addition to the constant cycling of nutrients, the availability of sunlight is vital in this changing landscape.
Where the rainforest experiences a disturbance of the canopy (for example, from a fallen tree, a fire or a cyclone), a gap in the canopy is created which prompts growth of fast-growing "pioneer" plant species that require high levels of sunlight. Once this re-growth has established shade cover, they are followed by slower-growing rainforest trees that prefer shade as they establish. A process called succession occurs as the shorter-lived pioneer species are replace by mature rainforest species. This succession process of recovering rainforest can take 500-600 years. In places where rainforest has been cleared completely, revegetation activities can be undertaken to recreate this process.
