Scale  Name of landscape metric  Abbreviations  Description  Unit 
AreaEdge indices  
Class  Class percent of landscape  PLAND  The proportion of total is occupied by a particular patch type: It a measures of dominance of patch type.  Percent 
Landscape/Class  Largest Patch Index  LPI  The proportion of total area occupied by the largest patch of a patch type.  Percent 
Landscape/Class  Patch Size Coefficient of Variation  AREA_CV  Patch size standard deviation divided by the mean patch size; a measure of relative variability. CV (coefficient of variation) equals the standard deviation divided by the mean, multiplied by 100 to convert to a percentage, for the corresponding patch metric.  None 
Landscape/Class  Edge Density  ED  Describe the distance of an ecosystem from its centroid (the center of the patch).  m/ha 
Shape index 




Landscape/Class  AreaWeighted Mean Shape Index  SHAPE_AM  A mean patchbase shape weighted by patch size.  None 
Aggregation Indices  
Landscape/Class  Number of Patches  NP  Express the number of patches identified for each class.  None 
Landscape/Class  Patch Density  PD  The number of patches of per hectare.  #100 ha 
Landscape/Class  Landscape Shape Index  LSI  The landscape boundary and total edge within the landscape divided by the total area, adjusted by a constant for a square standard.  None 
Landscape/Class  Patch Cohesion Index  COHESION  Patch cohesion index at the class level measures the physical connectedness of the corresponding patch type.  None 
Landscape  Clumpiness Index  CLUMPY  Clumpiness index is calculated from the adjacency matrix, which shows the frequency with which different pairs of patch types (including like adjacencies between the same patch type) appear sidebyside on the map. Clumpiness is scaled to account for the fact that the proportion of like adjacencies (Gi) will equal Pi for a completely random distribution.  Percent 
Diversity and connectivity indices  
Landscape  Patch richness  PR  This index reflects the number of patch types (vegetation types) in the bauxite mining landscape. It is a measure of diversity of patch type.  None 
Landscape  Shannonâ€™s Diversity Index  SHDI  Express the proportional abundance of every patch of a certain type of patch multiplied by a proportion.  Information 
Landscape  Perimeter Area Fractal Dimension Index  PAFRACMN  It reflects shape complexity across a range of spatial scales (patch sizes). Perimeterarea fractal dimension at the landscape level is identical to the class level.  None 
Landscape  Radius of Gyration Area Weighted Mean  GYRATE_AM  Radius of gyration is a measure of patch extent (i.e., how farreaching it is); thus, it is effected by both patch size and patch compaction.  Meters
