Several important concepts and definitions critical to the assessment of landscape structure are discussed. Graphic helps to illustrate how landscape metrics can be used to understand environmental condition and establish thresholds of change. Diagnosis of fragmentation and landscape sustainability conditions are essential to environmental planning and sustainable management of natural resources.

The program is almost completely automated and thus requires little technical training. An example using simulation modeling of American marten habitat change under four timber harvest scenarios XML: Riparia, a research Center at Penn State, has been assessing landscape conditions around its more than reference wetland sites.
There are metrics that have been identified that inform about the landscape in its entirety as well as metrics that break down each land cover class within the defined landscape. The raster version also computes several nearest neighbor metrics. Do Go to the Fragstats webpage.

Typically metrics are calculated for data classed within a specified landscape your extent. Using a moving window focal function, values were assigned to each pixel tabulating the percent of forested pixels within 1 km circle around that pixel.
Cluster analysis and Permutational Multivariate Analysis of Variance were used to test the null hypothesis of equal degrees of fragmentation and sustainability fragstatz among municipalities inrespectively.
