Hi, Welcome to OSM. In this changeset you removed a trail that seems to have a good amount of heatmap activity data, its visible in Lidar data, and some parts are visible with aerial imagery not covered by tree canopy. By all accounts it seems to exist on the ground regardless of being illegal. 

Looks like you have a new account, so I'll give you some info on the OSM project. If a trail actually exists on the ground should not be removed from OSM, regardless if it's private or public, designated or informal/illegal. Please don't remove valid data from OpenStreetMap.

The correct way to handle this is to use the tagging system. access=no seems to apply here. Once this is done, services that do use OSM data will reflect that and specify their access. 

Please read this for more info:

The trail should be restored and tagged correctly, making it access=no. Only once the trails is completely gone and overgrown, then it's okay to remove it.
