Maybe just not a wood duck place.
Tom
Our farm is mostly winter wheat and tallgrass prairie. However, we do have a 100' wide shelter belt of trees that was planted in the 1930s. We have very few nut trees, but like you, I have gotten some young ones planted.
We are definitely NOT a good wood duck place.
However, we do have a narrow live creek, that is mostly lined with various species of scrubby trees. I see a pair of wood ducks down on the creek every second or third winter.
If it is not too much work for you, I would keep trying to maintain your wood duck houses and habitat.
"If you build it, they will come." (Hopefully)
Good luck on your project!
