I also have 50 acres in ny that was timbered about 11 yrs ago.
Except deer have been thriving even immediately after.
As recent as last year heard 10 pt buck was spotteed on my land.

I did do some work, built a house that took about 3 yrs and was completed about 3 yrs ago.
It did change patterns, but didn't chase them away.
I am surrounded by larger lots and no farms,
Hard to say what's keepimg yours away,
Are others using you land?
Too much presence/ activity?
Good water source ?
When you say no deer, how about signs of deer? Scat, tracks etc..
Dogs yotes?
