Part 1. Using Spatial Statistics to Compare Mosaics Generated by Different Disturbances

In this first part of the lab, you will compare the spatial structure of the three different disturbance types (fires, bark beetle outbreaks, and clear-cut harvest) in the GYE. Five landscapes (5 × 5 km) of each disturbance type were sampled from disturbance maps generated from remote sensing data (Landsat, 30-m pixels, n = 15 different maps). These disturbance maps were created by analyzing differences between images taken before and after the disturbance event (Figure 11.2).
