The Nature Conservancy's top 10 nearest neighbors span journalists, politicians, activists, environmental organizations, and media channels — with no single entity pulling far ahead of the rest. Similarity scores range from 0.94 down to 0.91, a narrow band that defines the flat shape of this audience.

Treehugger leads at 0.94, the only website in the top 10, followed closely by journalist Caroline Orr Bueno at 0.93 and public radio program On Point at 0.92. The subcategory breakdown across the top 10 is telling: politicians appear three times (Sara Gideon at 0.91, Adam Parkhomenko at 0.91, Robert Reich at 0.90), journalists twice (Caroline Orr Bueno and Bill McKibben at 0.91), and environmental organizations twice — Sierra Club at 0.91 and World Wildlife Fund at 0.90. Rounding out the set are an academic (Seth Abramson, 0.91), a non-profit (Citizens for Ethics, 0.91), and an activist (Amy Siskind, 0.91).

The cross-kind character here is the dominant finding: only two of the ten neighbors share The Nature Conservancy's own Environmental subcategory. The rest are drawn from political, journalistic, and civic media spaces — suggesting this audience is shaped as much by civic and political engagement as by environmental identity.
