3.4 Cluster Analysis (CA)
AHC was performed on the data collected from 274 transects in three geographical locations (rural, rural–urban transitional, and urban) within the TGDR. This test grouped the sites based on their RHI and pressure indicator characteristics. The results categorized the sites into three major cluster groups, with rural (A), rural–urban transitional (B), and urban (C). The findings revealed that indices and sub-indices revealed distinct traits for various land uses. The outcomes are shown in Figure 8.
