From the trees that grow there, beech is completely a possibility, but I can’t find the little dashes that I usually see on the edge grain of beech wood, thus I eliminated that possibility. Still I don’t know if every beech look the same, so, maybe you’re right? Oak, ash and maple are all other possibilities for that forest, but maple was very unlikely, thus the other guesses (oak and ash) are completely plausible too.

Do you think of a test, or anything else I could do on the wood to help further determine the essence?

I didn’t know those terms as I’m a total woodwork newbie. Do you confirm the pictures I linked match what I called them?

Thanks very much everyone for your answers :-)
