I used the Greenness Index in GeoNadir as a proxy for plant diversity to visualize structural and spectral complexity rather than species richness. I conducted experiments in a 30 sq m sampling area at the UPOU Perma GARDEN.
High Diversity: The wide curve for Mixed Crops indicates a broad range of greenness values within that 30 sqm area. This "spectral heterogeneity" suggests differences in plant height, leaf structure, and phenological stage—traits typical of a polyculture or permaculture system.
Low Diversity: The "Dry Grass" (Blue line) shows a very tall, narrow peak. This indicates spectral homogeneity: almost every pixel reflects the same light quality, characteristic of a monoculture or uniform land cover.
