Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed [1] or transformed. [2] It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures.
The regime shift in the northern Benguela upwelling ecosystem is considered an example of ecosystem collapse in open marine environments. [24] Prior to the 1970s sardines were the dominant vertebrate consumers, but overfishing and two adverse climatic events ( Benguela Niño in 1974 and 1984) lead to an impoverished ecosystem state with high ...
These can reduce damage and erosion while simultaneously providing ecosystem services such as food production, nutrient and sediment removal, and water quality improvement to society [59] Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda.
The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far.
An example includes, varying aquatic insects are able to identify appropriate ponds to lay their eggs with the aid of polarized light to guide them, however, due to ecosystem modifications caused by humans they are led onto artificial structures which emit artificial light which are induced by dry asphalt dry roads for an example.

The European settlement period serves as a poignant example of how human activities can drastically impact natural ecosystems. In more recent times, overexploitation has resulted in the gradual emergence of the concepts of sustainability and sustainable development , which has built on other concepts, such as sustainable yield , [ 11 ] eco ...
If a species integral to an ecosystem has been lost due to extinction, a related species will be placed to fulfil the same role and re-establish the ecosystem function. These typically range from a related sub-species to another species within the same genus. [1] An example of such is the ecological services herbivores provide.
