I had checked with the mapping community on the osm Slack channel discussing these changes. The community was in agreement that many of these edits should be reverted. The guidance, between track/service being: highway=track roads access land, highway=service roads access facilities. The distinction here can be a bit muddled, but my rationale was this: roads that encourage traffic to specific places with infrastructure designed for specific activities, should be service. This would include the various boardwalk trails, picnic areas, boat launches, cabins/buildings, trailheads, etc. Pretty much anything with a sign, and some things without signs. Roads that access 'land' would be track. This would include dead end roads where logging roads use for access to the forest, or other roads hunters/birdwatchers/bushwhackers might use to access remote areas. The distinction between track/service (and many of the other highway= tags) has to do with how the roads are used, and doesn't reflect their condition. There are tags for tracktype=* and smoothness=* that describe the appropriateness of different types of vehicles, such as off-road capable trucks vs. standard sedans, etc. Further, something can be a highway, and be closed to traffic, or closed to non personnel of the land management team. There are many access= related tags to capture that information. 

I recognize that I'm primarily an armchair mapper but I don't make decisions willy-nilly. I also correct a lot of bad information in OSM. I invite those with better or more recent knowledge to correct any of my mistakes, just as I do for others. You are in a unique position to contribute really valuable information to the map for the lands you manage, but there are goals and standards of the OSM that might not line up with the goals and standards of the government agencies you work with. It's a delicate dance, but I encourage you to engage the community when you have questions.

I'd expect you to revert the changes you made, specifically the highway=* tagging. However, if you don't after a period of time, I'll go in and do what I think is appropriate.
