Rewilding
Rewilding is a form of ecological restoration aimed at increasing biodiversity and restoring natural processes. It differs from other forms of ecological restoration in that rewilding aspires to reduce human influence on ecosystems. It is also distinct from other forms of restoration in that, while it places emphasis on recovering geographically specific sets of ecological interactions and functions that would have maintained ecosystems prior to human influence, rewilding is open to novel or emerging ecosystems which encompass new species and new interactions. A key feature of rewilding is its focus on replacing human interventions with natural processes. Rewilding enables the return of intact, large mammal assemblages, to promote the restoration of trophic level, trophic networks. This mechanism of rewilding is a process of restoring natural processes by introducing or re-introducing large mammals to promote resilient, self-regulating, and self-sustaining ecosystems.

Species Reintroduction
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, Genetic diversity, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically Threatened species, threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment". Humans have been reintroducing species for food and pest control for thousands of years. However, the practice of reintroducing for conservation is much younger, starting in the 20th century.

David Foreman
William David Foreman (October 18, 1946 – September 19, 2022) was an American advocate for the conservation of wild lands and wildlife. He was a co-founder of three organizations: Earth First!, the Wildlands Project, and the Rewilding Institute. A prominent member of the radical environmentalism movement beginning in the 1980s, his advocacy and actions shifted in the early 1990s into collaborations with professionals in the field of conservation biology. Early life and education William David Foreman was born on October 18, 1946, in Albuquerque, New Mexico. His father was a United States Air Force sergeant and later an air traffic controller. Foreman attended San Antonio Junior College before transferring to the University of New Mexico, from which he graduated in 1967 with a degree in history. Early career In his early life he was active in conservative politics, campaigning for Barry Goldwater and forming the Young Americans for Freedom conservative youth chapter on hi ...

Keystone Species
A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. The concept was introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measur ...

UN Decade On Ecosystem Restoration
The United Nations Decade on Ecosystem Restoration runs from 2021 to 2030. Similar to other nature related international decades, its purpose is to promote the United Nations’ environmental goals. Specifically, to facilitate global cooperation for the restoration of degraded and destroyed ecosystems. Along with fostering efforts to combat climate change, safeguard biodiversity, food security, and water supply. While much focus is on promoting restoration activity by national governments, the UN also wishes to promote such efforts from other actors, ranging from the private sector and NGOs to regular individuals. Following on from the 2011 - 2020 United Nations Decade on Biodiversity, the decade on Ecosystem Restoration was launched in June 2021. The United Nations called for countries to follow through on existing pledges to restore a total area similar to the size of China by 2030. They also say the overarching goal of the decade is to catalyse a nature friendly movement that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecological Restoration
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can help to reverse biodiversity loss, combat climate change, support the provision of ecosystem services and support local economies. The United Nations has named 2021–2030 the Decade on Ecosystem Restoration. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. This may differ from historical baselines (the ecosystem's original condition at a particular point in time). To achieve successful habitat restoration, it is essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and shelter needed to supp ...

Pleistocene Megafauna
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, typically defined as animal species having body masses over , which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by their extreme size bias towards large animals (with small animals being largely unaffected), and widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence. The timing and severity of the extinctions varied by region and are generally thought to have been driven by humans, climatic change, or a combination of both. Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), as well as possibly environmental alteration. The relative importance of human vs climatic factors in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London. Along with its sister paper, ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in its journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectares
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is the ...

Local Government
Local government is a generic term for the lowest tiers of governance or public administration within a particular sovereign state. Local governments typically constitute a subdivision of a higher-level political or administrative unit, such as a nation or state. Local governments generally act within the powers and functions assigned to them by law or directives of a higher level of government. In Federation, federal states, local government generally comprises a third or fourth level of government, whereas in unitary states, local government usually occupies the second or third level of government. The institutions of local government vary greatly between countries, and even where similar arrangements exist, country-specific terminology often varies. Common designated names for different types of local government entities include county, counties, districts, city, cities, townships, towns, boroughs, Parish (administrative division), parishes, municipality, municipalities, mun ...

Landscape Connectivity
In landscape ecology, landscape connectivity is, broadly, "the degree to which the landscape facilitates or impedes movement among resource patches". Alternatively, connectivity may be a continuous property of the landscape and independent of patches and paths.Fischer, J. and D.B. Lindenmayer. 2006. Beyond fragmentation: the continuum model for fauna research and conservation in human-modified landscapes. Oikos, 112: 473–480. Connectivity includes both structural connectivity (the physical arrangements of disturbance and/or patches) and functional connectivity (the movement of individuals across contours of disturbance and/or among patches). Functional connectivity includes actual connectivity (requires observations of individual movements) and potential connectivity in which movement paths are estimated using the life-history data. A similar but different concept proposed by Jacques Baudry, landscape connectedness, refers to structural links between elements of spatial structures ...
