1. You only tagged the northern part of DeSoto National Forest
2. This area does not qualify as a leisure=park and is already tagged properly as a protected area.

See this excerpt from the wiki page about leisure=park:
" This tag is intended for (usually urban) parks with managed greenery, located within settlements and nearly always open to general public. Such an area may be known also as metropolitan park, municipal park (North America) or public park, public open space, or municipal gardens (UK)[2]. They are largely a "human-sculpted landscape.""

As such I'm reverting this changeset. If you have any questions, feel free to reply. Please reference the OSM wiki at https://wiki.openstreetmap.org in the future for proper mapping and tagging guidelines.
