Hello, some of these area tags are incorrect. The farmland along the Humboldt River would be more correct tagged as meadows since they appear to be used for grazing rather than growing crops, and a lot of what is tagged as natural wood would be better tagged as scrub and wetland since it's mostly inundated shrubbery/stunted trees or reed with very coverage from trees that would warrant calling it woodland (https://www.openstreetmap.org/way/885010630 for instance).
