Approaches to Understanding Habitat Fragmentation
Two approaches that are typically used to understand habitat fragmentation and its ecological impacts

Species Oriented Approach:
The species oriented approach focuses specifically on individual species and how they each respond to their environment and habitat changes with in it. This approach can be limited because it does only focus on individual species and does not allow for a broad view of the impacts of habitat fragmentation across species.

Pattern Oriented Approach
The pattern oriented approach is based on land cover and its patterning in correlation with species occurrences. There are typically two models of study for landscape patterning which include the patch-matrix-corridor model developed by Richard Forman. The other model is the variegation model. Variegated landscapes retain much of their natural vegetation but are intermixed with gradients of modified habitat </ref

Causes and Types of Habitat Fragmentation
There are two types of processes that can lead to habitat fragmentation. There are exogenous processes and endogenous processes. Endogenous are process that develop as a part of a species biology so they typically include changes in biology, behavior and interactions within or between species. Endogenous threats can result in changes to breeding patterns or migration patterns and are often triggered by exogenous processes. Exogenous processes are independent of species biology and can include habitat degradation, habitat subdivision or habitat isolation. These processes can have a substantial impact on endogenous processes by fundamentally altering species behavior. Habitat subdivision or isolation can lead to changes in dispersal or movement of species including changes to seasonal migration. These changes can lead to decrease in a density of species, increased competition or even increased predation.
