Editing Habitat fragmentation (section)

==== Variegation model ====
The other model is the variegation model. Variegated landscapes retain much of their natural vegetation but are intermixed with gradients of modified habitat <ref>{{cite web|title=Landscape Ecology and Landscape Change|url=http://www.veac.vic.gov.au/reports/Chapter%202%20-%20Landscape%20Ecology%20and%20Landscape%20Change.pdf|access-date=March 22, 2018|ref=2}}</ref> This model of habitat fragmentation typically applies to landscapes that are modified by agriculture. In contrast to the fragmentation model that is denoted by isolated patches of habitat surrounded by unsuitable landscape environments, the variegation model applies to landscapes modified by agriculture where small patches of habitat remain near the remnant original habitat. In between these patches are a matrix of grassland that is often modified versions of the original habitat. These areas do not present as much of a barrier to native species.<ref>{{cite journal |last1=McIntyre |first1=S. |last2=Barrett |first2=G.
