The veld ecosystem relies on periodic fire disturbances like these to rejuvenate itself. In ecology, a disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem. Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements.

Sydney Tar Ponds and Coke Ovens sites in the city of Sydney, Nova Scotia, Canada, known as the largest toxic waste site in North America.

A diagram of the typical drivers of ecosystem collapse. [1]While collapse events can occur naturally with disturbances to an ecosystem—through fires, landslides, flooding, severe weather events, disease, or species invasion—there has been a noticeable increase in human-caused disturbances over the past fifty years.
Gap dynamics are the result of disturbances within an ecosystem. There are both large scale and small scale disturbances, and both are influenced by duration and frequency. These all affect the resulting impact and regeneration patterns of the ecosystem. The most common type of disturbance within a tropical ecosystem is fire.
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil ...
Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda. Natural vegetation along this coastal shoreline in North Carolina, US, is being used to reduce the effects of shoreline erosion while providing other benefits to the natural ecosystem and the human community.
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
Ecological extinction is an example of a definitive point of no return. Ecological thresholds are often characterized by hysteresis, which means the dependence of the state of a system on the history of its state. Even when the change is not irreversible, the return path from altered to original state can be drastically different from the ...
