Hi, and thanks for contributing.

It looks like you have been changing a lot of features from leisure=nature_reserve into leisure=park. I believe that in these cases, leisure=nature_reserve was the correct tag; the OSM definition for leisure=park is more strict than how the term is typically used in the US. Please take a look at the wiki page (especially the "Mapping history in the USA" section) to see what I mean: https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dpark
