Aside from some evolutionary estimates, evidence for trees only find traditional tree-ring dating on any single timber found growing to an age of no more than 2,500 years. This is also well within the ages of the oldest living bristlecone pines and other old trees found around the world including the Bristlecone pines which are native to the Rocky Mountains of the United States.
If the flood of Noah really occurred about 5,000 years ago then there should be nothing living older than that time frame and this is exactly what evidence indicates. Tree ring dating methods also vary depending on drought or flood conditions so this dating method like all of them is riddled with assumptions.
