15. GIS analysis
We used Idrisi 32 software to analyze the level of fragmentation in the landscape. The
fragmentation index is a value that has a range between 0 and 1. If the polygons are classified mostly
into the same class, the fragmentation index becomes 0. If polygons are in a class different from
adjacent polygons, the fragmentation index becomes 1. We also roughly estimated the distance from
each plot to the nearest forest patch using the measuring tool of ArcView.
16. Statistical analysis
We used one-way ANOVA and multiple comparison statistics with SPSS software and MS
Excel for the statistical and graphical analyses.
