Map showing funding received by U.S. conservation organizations

I was curious to know how much funding is deployed to conservation efforts near me. I started by pulling a list of organizations using conservation-related tax codes, and cross referencing with the Land Trust Alliance and a few other sources. Financial records for 501(c)3 non-profit organizations in the U.S. are publicly accessible. So, once I had a list of organizations, I was able to fetch recent financial records for all organizations. I then plotted all funding values on the map using the organization's location.

The largest organizations are active all over the world, so their values should be excluded from any sort of local analysis. The area near DC, for example, shows billions in funding due to organizations such as the Nature Conservancy.

Curious to hear what y'all glean from this. Is there anything you'd like to see included in the map?
