=0A=0AHello Dave, Heather and all,=0A=0AI'd be inclined to side with Dave, =
it seems unlikely the tree was over 400 years old. I just did a little rese=
arch, and found this website which claims that the oldest red oak (Quercus =
rubra) was measured in Netherlands in 2011. It was 210 years old +/- 10 yea=
rs, and had a diameter of=A0 5.84m! To put this in perspective, the red oak=
 in the Nature NS big-tree registry with the largest diameter was 2.84m.=0A=
=0AIt should be noted however that a large diameter tree does not always in=
dicate an old tree and vise-versa. A=A0 long-lived tree that has grown in u=
nfavorable conditions=A0 could live to a ripe old age without reaching an e=
normous diameter. If you ever age black spruce in a swamp, you'd be amazed =
how old a small tree can be!=0A=0AThis being said, it should definitely be =
looked at! If no-one checked the age of trees, we wouldn't ever find the re=
cords! It would be great to get a ring count. If you're not able to get a g=
ood look at the rings, can you get a positive ID on the species of oak? If =
it's an oak from Europe, I think we can say with confidence that it's not o=
lder than 400 years.=0A=0AIan
