### Unveiling Dynamic Species Diversity: Exploring Variations across Locations, Years, and Seasons  
Significant variations in species diversity indicators were detected across different locations, with year and season exerting varying influences (Table 2, Figure 3). The richness index exhibited substantial divergence by location (\(p<0.001\)), as did the Shannon diversity index (\(p<0.001\)); an interaction between location and season also surfaced (\(p=0.027\)). Additionally, the Simpson diversity index reflected significant differences based on location (\(p<0.001\)) and across all interactions. Notably, the evenness index displayed noteworthy disparities across all factors and interactions. Findings from the vegetation survey delineated a richer diversity of plant species within forested domains compared to non-forest realms. This observation is consistent with a prior study that found that forests harbor higher plant diversity owing to their intricate habitat structure and microclimate [33]. The Shannon-Weaver, Simpson, and Margalef species richness indices demonstrated elevated values within the forested regions, underscoring a more diverse and evenly distributed plant community [10].
