      Why is central Virginia relatively low to the areas that surround it?

      I wonder what this map looks like if you only did natives. I know the Smokies is the most native tree diverse national park.

      are trees what will ultimately break my will to stay out of the south for the rest of my life? trees? am i going to florida for TREES? hahahah

      Not sure Im buying this one. I would be interested to know what kind of criteria they used to judge the dispersion of species, particular the granularity of the dispersion areas.

    5. It means 1 or just a few species, so it probably varies spatially as far as which species is where, but my guess would be a lot of those areas have only native Cottonwood species

    6. I find it interesting that this path is also indicative of paths that Hurricanes hit

    7. This is cool I never expected western tree diversity to be so low. Makes sense for the desert areas but I thought in the mountains would have a more pronounced increase in diversity. TIL

      There’s a hypothesis that the Apalachicola-Chattahoochee-Flint River basin acts as a route of dispersal and habitat refuge for species between the Gulf of Mexico coastal plain and Southern Appalachians, which allowed more species to survive repeated glacial events over millenia and is a place where two already diverse floristic regions can overlap. (Hence the biodiversity hotspot in the Florida panhandle)

      Monoculture is gonna be what ultimately kills us. One blight and we screwed.

      Somehow, this isn’t making sense to me… California is considered the most biodiverse state in the country and has multiple climate zones and ecological niches in one state. I would think it would have the highest tree diversity relative to other states. I look at the Bay Area and Central Valley on up into the Sierra foothills and there is diversity unlike anywhere else I have been with plants and trees from a wide range of planting zones in them. What am I missing?

    11. Ah yes the very diverse trees in *checks notes* the middle of the cornfields of Illinois.

      My favorite part of this is that you can clearly see the Hudson Valley! So pretty and deserving of the show offs

      I live in a tree dense area. What does the blue look like? I can assume desert for Nevada, but everywhere else is really strange and foreign to me. How do you only have one type of tree per sq mile?

    14. Maria_Dragon on

      This has large parts of  Idaho around the Snake River Valley as only one type of tree and that is simply untrue. So I don’t trust the blue areas.

    15. Also a map of rainfall and orographic effect. Very dry for a large chunk of the year reduces biodiversity down to the most drought adapted species.

      It’s kind of a shame about the lower Mississippi. I’d imagine the tree diversity would be extremely high in that area if not for human agriculture

    17. I’d be curious to see a similar map for Europe. I imagine it would be mostly a south-north gradient with the Mediterranean region being richer while the northern relatively more species poor. But maybe I’m wrong and it would be an unexpected pattern!
