Edge Effect
Distortion or bias in spatial analysis results near the boundaries of a study area (standard GIS usage).
What is Edge Effect?
The term "edge effect" describes the shifts in ecological processes or environmental conditions that take place at the border or edge between two distinct ecosystems or types of land cover, such as grassland and forest. In comparison to the interior regions of each ecosystem, these edge zones frequently have distinct microclimates, species interactions, and resource availability.
Edge effects can affect species distribution, habitat quality, and biodiversity in ecology and geography. Some species, for instance, might flourish close to edges because of the increased sunshine or food sources, while others might suffer from increased exposure to predators or human activity. Decisions on land use, habitat management, and conservation planning all depend on an understanding of edge effects.

Changes in population or community patterns that take place along the border between two distinct ecosystems or habitats are referred to as the edge effect in ecology. Because these edge locations incorporate resources and conditions from both adjacent environments, they frequently exhibit higher species diversity and abundance than inner habitats. But margins can also put animals at greater risk from things like invasive species, human disturbance, and predation.
The division of vast environments into smaller, isolated areas is known as habitat fragmentation. At these patches' borders, the edge effect takes place, altering the environment in ways that can reduce biodiversity, increase predation, and benefit invading species.
In biodiversity, the term "edge effect" describes the shifts in species abundance and composition that take place at the border between two distinct habitats or ecosystems, like a forest and a grassland. Because edges offer conditions and supplies from both adjacent habitats, they frequently have a higher species variety. Sensitive species may occasionally suffer as a result of their increased susceptibility to invasive species, predators, and human disturbances.
The intersection of a forest and grassland serves as an illustration of the ecological edge effect. A distinct environment is created at this boundary by differences in sunlight, temperature, and wind compared to the interior regions. Higher biodiversity is frequently supported by this boundary, drawing species from both ecosystems. For example, deer eat at the forest edge while birds and insects use the open grassland.
