Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. This is done within a variety of landscape scales, development spatial patterns, and organizational levels of research and policy. Concisely, landscape ecology can be described as the science of "landscape diversity" as the synergetic result of biodiversity and geodiversity.
Urban ecology is the scientific study of the relation of living organisms with each other and their surroundings in an urban environment. An urban environment refers to environments dominated by high-density residential and commercial buildings, paved surfaces, and other urban-related factors that create a unique landscape. The goal of urban ecology is to achieve a balance between human culture and the natural environment.
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment, and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats.
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. Connectivity includes both structural connectivity and functional connectivity. Functional connectivity includes actual connectivity and potential connectivity in which movement paths are estimated using the life-history data.
MARXAN is a family of software designed to aid systematic reserve design on conservation planning. With the use of stochastic optimisation routines Marxan generates spatial reserve systems that achieve particular biodiversity representation goals with reasonable optimality. Over the years, Marxan has grown from its standard two zone application to consider more complex challenges like incorporating connectivity, probabilities and multiple zones. Along the way, Marxan’s user community has also built plug-ins and interfaces to assist with planning projects.
A wildlife corridor, habitat corridor, or green corridor is an area of habitat connecting wildlife populations separated by human activities or structures. This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding, and reduced genetic diversity that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events. This may potentially moderate some of the worst effects of habitat fragmentation, wherein urbanization can split up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to access resources. Habitat fragmentation due to human development is an ever-increasing threat to biodiversity, and habitat corridors serve to manage its effects.
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. 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, and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. When such thresholds are associated with a critical or bifurcation point, these regime shifts may also be referred to as critical transitions.
Earthwatch Institute is an international environmental charity. It was founded in 1971 as Educational Expeditions International by Bob Citron and Clarence Truesdale. Earthwatch Institute supports Ph.D. researchers internationally and conducts over 100,000 hours of research annually. Using the Citizen Science methodology, Earthwatch's mission statement is "to engage people worldwide in scientific field research and education to promote the understanding and action necessary for a sustainable environment." As such, it is one of the global underwriters of scientific field research in archaeology, paleontology, marine life, biodiversity, ecosystems and wildlife. For over forty years, Earthwatch has raised funds to recruit individuals, students, teachers, and corporate fellows to participate in critical field research to understand nature's response to accelerating global change.
An intact forest landscape (IFL) is an unbroken natural landscape of a forest ecosystem and its habitat–plant community components, in an extant forest zone. An IFL is a natural environment with no signs of significant human activity or habitat fragmentation, and of sufficient size to contain, support, and maintain the complex of indigenous biodiversity of viable populations of a wide range of genera and species, and their ecological effects.
Ecosystem management is an approach to natural resource management that aims to ensure the long-term sustainability and persistence of an ecosystem's function and services while meeting socioeconomic, political, and cultural needs. Although indigenous communities have employed sustainable ecosystem management approaches implicitly for millennia, ecosystem management emerged explicitly as a formal concept in the 1990s from a growing appreciation of the complexity of ecosystems and of humans' reliance and influence on natural systems.
The Paroo-Darling National Park is a protected national park that is located in the Far West region of New South Wales, in eastern Australia. The 178,053-hectare (439,980-acre) national park spans two distinct regions in the outback area. This region covers the arid catchments of the Paroo River and the Paroo-Darling confluence to the south.
Livingstone is a national park and state conservation area located 30 kilometres (19 mi) south of Wagga Wagga and 10 kilometres (6.2 mi) east of Mangoplah, in the South West Slopes region of south western New South Wales.
Gary Tabor is an American environmentalist with over 30 years' experience working on behalf of large scale conservation internationally as well as 12 years as a leader within the U.S. environmental philanthropic community. Tabor is known for his role as a catalyst in forwarding progress through large landscape conservation, pioneering the fields of Conservation Medicine and EcoHealth, and advising agencies and organizations about contemporary environmental issues.
The Great Eastern Ranges extends from southern Victoria to the north of Cairns in Queensland, Australia, encompassing the Great Dividing Range and the Great Escarpment – two very old, mountainous, sometimes undulating an occasional tableland landscapes situated on the eastern side of the continent.
The Peel watershed drains 14% of the Yukon Territory Canada and flows into the Beaufort Sea via the Peel and then Mackenzie Rivers. While the lower part of the Peel River and its confluence with the Mackenzie River are in the North West Territories, most of the watershed, 68,000 km2 out of 77,000 km2 is in the Yukon. Six major tributaries and numerous smaller streams feed the Peel. The Yukon portion of the watershed is undergoing land use planning, a process laid out in Chapter 11 of the Yukon Land Claims Agreement and is called the Peel Watershed Planning Region (PWPR). This article is confined to the PWPR.

He specialises in large-scale, long-term research monitoring programs in south-eastern Australia, primarily in forests, reserves, national parks, plantations, and on farm land.
Climate change in Mexico is expected to have widespread impacts on Mexico: with significant decreases in precipitation and increases in temperatures. This will put pressure on the economy, people and the biodiversity of many parts of the country, which have largely arid or hot climates. Already climate change has impacted agriculture, biodiversity, farmer livelihoods, and migration, as well as water, health, air pollution, traffic disruption from floods, and housing vulnerability to landslides.
