Can I use different species of timbers from my own property in my barn?

Asked by Jeff S from Buchanan, MI USA

I would like to build a barn based on your 30×50 plans. I have 22 acres of hardwoods and would like to cut my timbers and siding with a portable sawmill.

I have many species to choose from–ash, black oak, red oak, cherry, cottonwood/tulip.

What trees would be best?

I had a Forester come in and say I should have my 100 Ash trees logged because of the Ash Borer disease.

Is one species better for siding or structural timbers? I’m in southwest Michigan.
