Most counties have GIS 'parcel viewer' pages online. As with old roads, terrain traps, maps, things on the ground subject to change. Obviously, resources are limited versus flashy stuff like RASTA zones, Devils Path parking, etc. And yes, being respectful and mindful seems good policy. Honestly, its been a cool way to meet several neighbors.
If ya wanna get existential with it, do humans own the forest? More practically, I think nature and recreation are things worth managing for. With BC stuff around me being quiet, it's harder to share the pow pics, gauge either side's intentions, address or even be aware of any issues. More fun to be skiing anyway.
But important stuff to talk about imo.
Though parallel botany and MTB realms of mine, I get to deal with invasive plants and ninja trails that ultimately hurt the cause, despite good intentions. That said if I followed every rule my world of trails would be way tinier...
