Greetings Aaron:
Sorry, but extension forestry does not estimate or appraise trees, logs, lumber via this forum. Estimates or appraisals need to be conducted on-site by a professional or a reputable individual. Alternatively, please use the Illinois Timber Prices Bulletin to estimate standing timber values and free on board pricing here in Illinois.

Volume estimate for Tree 1 at 26" dbh with one 16' sawlog = 272 bf (Doyle). Volume estimate for Tree 2 at 21" dbh with 14' sawlog = 147 bf (Doyle).
