My
land is literally marked by
deer paths which help the other animals to find their way.

Making use of something new or added will make the animal afraid rather than helping. My observation is that the animals don't like things that are new to them.
I believe that someone at
Wheaton Labs posted a picture of a trail that some animals had used. I doubt that I would ever find it doing a search.
I asked on Pinterest and found these:
