AnalysisFRAGSTATS• Each 3.2 km buffer analyzed• Number of patches, mean patch size,
area of each class, total edge, edge density, mean patch edge, and other spatial statistics calculated
• t-Tests used to compare spatial statistics of lek locations to random locations
• 1992, 2001, and 2011 NLCD layers used to look at change over time

Increase Scale
• 10 mile buffer
• 83 new random locations
• 3.2 km buffer around each random location
