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 ---2114655128-1723118488-1348589351=:43658 Content-Type: text/html; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable <html><body><div style=3D"color:#000; background-color:#fff; font-family:ti= mes new roman, new york, times, serif;font-size:12pt"><div><span>Hi Ian and= those interested in Old Age</span></div><div style=3D"color: rgb(0, 0, 0);= font-size: 16px; font-family: 'times new roman', 'new york', times, serif;= background-color: transparent; font-style: normal; "><span>My observations= from the woodpile of knowledge in my yard</span></div><div style=3D"color:= rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york',= times, serif; background-color: transparent; font-style: normal; "><span>i= s the older a tree the smaller the rings.
