Ecosystem Restoration
Restoration ecology is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human interruption and action. Effective restoration requires an explicit goal or policy, preferably an unambiguous one that is articulated, accepted, and codified. Restoration goals reflect societal choices from among competing policy priorities, but extracting such goals is typically contentious and politically challenging. Natural ecosystems provide ecosystem services in the form of resources such as food, fuel, and timber; the purification of air and water; the detoxification and decomposition of wastes; the regulation of climate; the regeneration of soil fertility; and the pollination of crops. These ecosystem processes have been estimated to be worth trillions of dollars annually. There is consensus in the scientific community that the current env ...

Wetland Restoration In Australia
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reforestation
Reforestation (occasionally, reafforestation) is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation, but also after clearcutting. Management A debated issue in managed reforestation is whether or not the succeeding forest will have the same biodiversity as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a monoculture forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different selections of seedlings taken from the area, often of multiple species. Another important factor is the natural regeneration of a wide variety of plant and animal species that can occur on a clear cut. In some areas the suppression of forest fires for hundreds of years has resulted in large single aged and single species forest stands. The logging of small clear cuts an ...

Civilian Conservation Corps
The Civilian Conservation Corps (CCC) was a voluntary government work relief program that ran from 1933 to 1942 in the United States for unemployed, unmarried men ages 18–25 and eventually expanded to ages 17–28. The CCC was a major part of President Franklin D. Roosevelt's New Deal that supplied manual labor jobs related to the conservation and development of natural resources in rural lands owned by federal, state, and local governments. The CCC was designed to supply jobs for young men and to relieve families who had difficulty finding jobs during the Great Depression in the United States Robert Fechner was the first director of this agency, succeeded by James McEntee following Fechner's death. The largest enrollment at any one time was 300,000. Through the course of its nine years in operation, three million young men took part in the CCC, which provided them with shelter, clothing, and food, together with a wage of $30 (equivalent to $1000 in 2021) per month ($25 of ...

University Of Wisconsin–Madison Arboretum
The University of Wisconsin–Madison Arboretum is a teaching and research facility of the University of Wisconsin–Madison and the site of historic research in ecological restoration. In addition to its in Madison, Wisconsin (located about four miles from the main campus of the University of Wisconsin–Madison), the Arboretum also manages of remnant forests and prairies throughout Wisconsin. It was designated a National Historic Landmark in 2021, in recognition for its role as a pioneer in the field of ecological restoration. History In 1911, landscape architect John Nolen proposed an arboretum for Madison based on Boston's Arnold Arboretum. The UW Arboretum was founded on April 26, 1932, when the University Board of Regents accepted the deeds to 6 parcels, 246 acres of land on the southwestern end of Madison's Lake Wingra, creating the "University of Wisconsin Forest Preserve Arboretum and Wildlife Refuge". The acreage at the time was mostly farmland fields and pastures. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tallgrass Prairie
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba. They were characteristically found in the central forest-grasslands transition, the central tall grasslands, the upper Midwest forest-savanna transition, and the northern tall grasslands ecoregions. They flouris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Peoples
Indigenous peoples are culturally distinct ethnic groups whose members are directly descended from the earliest known inhabitants of a particular geographic region and, to some extent, maintain the language and culture of those original peoples. The term ''Indigenous'' was first, in its modern context, used by Europeans, who used it to differentiate the Indigenous peoples of the Americas from the European settlers of the Americas and from the Sub-Saharan Africans who were brought to the Americas as enslaved people. The term may have first been used in this context by Sir Thomas Browne in 1646, who stated "and although in many parts thereof there be at present swarms of ''Negroes'' serving under the ''Spaniard'', yet were they all transported from ''Africa'', since the discovery of ''Columbus''; and are not indigenous or proper natives of ''America''." Peoples are usually described as "Indigenous" when they maintain traditions or other aspects of an early culture that is assoc ...

University Of Wisconsin–Madison
A university () is an educational institution, institution of higher education, higher (or Tertiary education, tertiary) education and research which awards academic degrees in several Discipline (academia), academic disciplines. Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation ...

Bill Jordan (environmental Critic)
hoto by Barbara Jordan Bill Jordan (born 1944), more formally William R. Jordan III, is an American botanist and journalist who has played a leading role in the development and critique of ecological restoration as a means of developing an environmentalism that is philosophically more coherent, psychologically more productive, politically more robust, and ecologically more effective. His critique has had a significant influence on environmentalism in the United States and abroad. Jordan worked for 24 years at the University of Wisconsin's Arboretum in Madison. This was the site of early attempts to recreate historic ecological communities, such as tallgrass prairies and maple forests, an effort led by the famed conservationist Aldo Leopold. In 1981 Jordan founded and served as editor of the journal ''Restoration & Management Notes'' (now ''Ecological Restoration''), and he was a founding member of the Society of Ecological Restoration. He has been called the first person to wri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Local Adaptation
Local adaptation is a mechanism in evolutionary biology whereby a population of organisms evolves to be more well-suited to its local environment than other members of the same species that live elsewhere. Local adaptation requires that different populations of the same species experience different natural selection. For example, if a species lives across a wide range of temperatures, populations from warm areas may have better heat tolerance than populations of the same species that live in the cold part of its geographic range. Definition More formally, a population is said to be locally adapted if organisms in that population have evolved different phenotypes than other populations of the same species, and local phenotypes have higher fitness in their home environment compared to individuals that originate from other locations in the species range. This is sometimes called 'home site advantage'. A stricter definition of local adaptation requires 'reciprocal home site advantage' ...

Native Species
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...
