Hello, welcome to OSM. Seems like the features you removed in this changeset are valid. Please don’t remove valid OSM data.

You have a new account and might not be aware, On OSM, we do not removed features if they exist on the ground. If it exists on the ground, it is valid data regardless of a feature being public, or private, designated or informal/illegal/unauthorized. Removing them is actually considered vandalism.

Trails that exist, but are "not publicly available", is an invalid reason to remove data from OSM. So this edit is incorrect and damaging to valid OSM data.

The correct way to handle this is to use OSM's tagging system. access=private, or access=no would be appropriate if they are closed the public. Once this is done, services that do use OSM data will reflect that and specify their access.
