My guess is that you are asking in order to run into a batch of Morel's That said, and seeins how you are in Fayette, you should do more searching for the numerous Elms that have dutch Elm disease. GOLD MINE.
As far as rendering Poplar to firewood. Not worth the time. Burns quickly and provides very little BTU's.
My former in-laws had them all over their property in Northern VA. The soil was very poor and mostly grew nothing but boulders and something that tried to be a lawn. These particular trees were very tall, had extremely straight trunks and had a habit of snapping off close to the top in relatively mild winds. The leaves were a mess in the fall. I think the lumber can be used as interior support structures in furniture making.
We had lots of them on the Paint Borough Sportsmen's Club property. I say had because we just sold off out timber to pay for the rifle range expansion we are currently doing. They can be found throughout Somerset and Cambria County.
