|
adaptive management
|
A component of ecosystem management in which management actions are seen as experiments and future management decisions are determined by the outcome of present decisions.
|
|
|
biological reserve
|
An often small nature reserve established with the conservation of a single species or ecological community as the main conservation objective.
|
|
|
buffer zone
|
A portion of a nature reserve surrounding a core natural area where controls on land use are less stringent than in the core natural area, yet land uses are at least partially compatible with many species’ resource requirements. Compare core natural area.
|
|
|
core natural area
|
A portion of a nature reserve where the conservation of biodiversity and ecological integrity takes precedence over other values or uses. Compare buffer zone.
|
|
|
ecosystem management
|
An approach to habitat management in which scientifically-based policies and practices guide management decisions on how best to meet an overarching goal of sustaining ecosystem structure and function for long periods of time.
|
|
|
edge effects
|
Biotic and abiotic changes that are associated with an abrupt habitat boundary such as that created by habitat fragmentation.
|
|
|
extent
|
In landscape ecology, the area or time period over which observations are collected for a region under study; together with grain, extent characterizes the scale at which a landscape is studied. Compare grain.
|
|
|
grain
|
In landscape ecology, the size of the smallest homogeneous unit of study (such as a pixel in a digital image), which determines the resolution at which a landscape is observed; together with extent, grain characterizes the scale at which a landscape is studied. Compare extent.
|
|
|
habitat corridor
|
A relatively narrow patch that connects blocks of habitat and often facilitates the movement of species between those blocks.
|
|
|
heterogeneity
|
The quality or state of consisting of dissimilar elements.
|
|
|
landscape
|
An area that is spatially heterogeneous either in its elements (such as the vegetative cover types found at different locations) or in how those elements are arranged.
|
|
|
landscape composition
|
In landscape ecology, the kinds of elements or patches comprised by a landscape and how much of each kind is present.
|
|
|
landscape ecology
|
The study of landscape patterns and the effects of those patterns on ecological processes.
|
|
|
landscape structure
|
In landscape ecology, the physical configuration of the different compositional elements of a landscape.
|
|
|
mosaic
|
A composite of heterogeneous elements.
