A new report from Auburn University says the fire that damaged the oak trees at Toomer's Corner will make the trees even weaker than they were beforehand.
A study released on Monday says the trees already were in what it calls a "severe state of decline" from being poisoned.
The report says flames that severely damaged the trees on Nov. 18 will only worsen their condition.
It says damage will likely leave the trees without foliage all winter, reducing photosynthesis to even lower levels. That's important because plants use photosynthesis to survive.
Auburn police say no one has been charged in the fire, which occurred while the trees were rolled with toilet paper after a football victory.
An Alabama fan charged with poisoning the trees is undergoing mental screening.
