Rewilding (conservation biology) in the context of "Ecosystem engineer"

Wildlife management is the management process influencing interactions among and between wildlife, its habitats and people to achieve predefined impacts. Wildlife management can include wildlife conservation, population control, gamekeeping, wildlife contraceptive and pest control.

Wildlife management aims to halt the loss in the Earth's biodiversity, by taking into consideration ecological principles such as carrying capacity, disturbance and succession, and environmental conditions such as physical geography, pedology and hydrology. Most wildlife biologists are concerned with the conservation and improvement of habitats; although rewilding is increasingly being undertaken. Techniques can include reforestation, pest control, nitrification and denitrification, irrigation, coppicing and hedge laying.

Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, manmade rewilding projects, accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, or other cause. Originally the process was simply one of applying seed and fertilizer to disturbed lands, usually grasses or clover. The fibrous root network of grasses is useful for short-term erosion control, particularly on sloping ground. Establishing long-term plant communities requires forethought as to appropriate species for the climate, size of stock required, and impact of replanted vegetation on local fauna. The motivations behind revegetation are diverse, answering needs that are both technical and aesthetic, but it is usually erosion prevention that is the primary reason. Revegetation helps prevent soil erosion, enhances the ability of the soil to absorb more water in significant rain events, and in conjunction reduces turbidity dramatically in adjoining bodies of water. Revegetation also aids protection of engineered grades and other earthworks.

Organisations like Trees For Life (Brooklyn Park) provide good examples.

Knepp Wildland is the first major lowland rewilding project in England. It comprises 1,400 hectares (3,500 acres) of former arable and dairy farmland in the grounds of Knepp Castle, in West Sussex.

Since 2000 when the conversion from intensive agriculture started, the land now supports many rare species including turtle doves, barbastelle bats, slow-worms and barred grass snakes; it has become a major nesting site for nightingales; a breeding hotspot for purple emperor butterflies; the site of the first white stork chicks raised in the wild in England for 600 years, and is home to the first beavers living in the wild in Sussex for 400 years. On 17 November 2021, the very rare vagrant emperor dragonfly (Anax ephippiger) was discovered in one field.

Permaculture is an approach to land management and settlement design that adopts arrangements observed in flourishing natural ecosystems. It includes a set of design principles derived using whole-systems thinking. It applies these principles in fields such as regenerative agriculture, town planning, rewilding, and community resilience. The term was coined in 1978 by Bill Mollison and David Holmgren, who formulated the concept in opposition to modern industrialized methods, instead adopting a more traditional or "natural" approach to agriculture.

Multiple thinkers in the early and mid-20th century explored no-dig gardening, no-till farming, and the concept of "permanent agriculture", which were early inspirations for the field of permaculture. Mollison and Holmgren's work from the 1970s and 1980s led to several books, starting with Permaculture One in 1978, and to the development of the "Permaculture Design Course" which has been one of the main methods of diffusion of permacultural ideas. Starting from a focus on land usage in Southern Australia, permaculture has since spread in scope to include other regions and other topics, such as appropriate technology and intentional community design.

Land restoration, which may include renaturalisation or rewilding, is the process of restoring land to a different or previous state with an intended purpose. That purpose can be a variety of things such as what follows: being safe for humans, plants, and animals; stabilizing ecological communities; cleaning up pollution; creating novel ecosystems; or restoring the land to a historical condition, for example how indigenous people managed the land.

Ecological destruction or degradation, to which land restoration serves as an antidote, is usually the consequence of human influence's intended or unintended consequences. This can include pollution, deforestation, salination, or species endangerment, among many more. Land restoration is not the same as land reclamation, where existing ecosystems are altered or destroyed to give way for cultivation or construction. Land restoration can enhance the supply of valuable ecosystem services that benefit people.
