فهرست کهنسال‌ترین درختان
درخت‌های کلونی

مانند همه گیاهان و قارچ‌های طولانی مدت، هیچ بخش جدا از پرگَنهٔ تاگی زنده نیست (به معنای متابولیسم فعال) بیش از کسری بسیار کمی از زندگی کل کلون. برخی از پرگنه‌ها ممکن است کاملاً از طریق سیستم‌های ریشه ای خود متصل شوند، در حالی که بیشتر آنها به هم پیوسته نیستند، اما کلون‌های ژنتیکی یکسان هستند که از طریق تولید مثل رویشی ، منطقه را جمع می کنند. تخمین‌ها برای پرگنه‌های تاگی، اغلب براساس نرخ رشد فعلی است.

| --- | --- | --- | --- | --- | --- |
| Antarctic Beech | less than 70 million years | Antarctic beech Nothofagus moorei | Repeater Station Road, Springbrook National Park, Queensland | Australia | Three individuals approximately 2000 years old are the parent trees to others in the surrounding forest; they grow clones by coppicing new shoots radially, forming a ring at the base of the parent tree trunk. |
| Wollemi Pines | 60+ million years | Wollemi pine Wollemia nobilis | Wollemi National Park, New South Wales | Australia | According to Cris Brack and Matthew Brookhouse at the ANU Fenner School of Environment & Society: "Once you accept that a common, genetically identical stock can define a tree, then the absolute “winner” for oldest tree (or the oldest clonal material belonging to a tree) [in Australia] must go to the Wollemi pine (Wollemia nobilis). It may be more than 60 million years old. The Wollemi pine clones itself, forming exact genetic copies. It was thought to be extinct until a tiny remnant population was discovered in Wollemi National Park in 1994... There is also substantial evidence that the tree has been cloning itself and its unique genes ever since it disappeared from the fossil record more than 60 million years ago." |
| Unknown | 43,600–130,000 | King's lomatia Lomatia tasmanica | Southwest National Park, Tasmania | Australia | Lomatia tasmanica is an endangered species with only one population, consisting of several hundred genetically identical individuals. Although it flowers occasionally, fruit production has never been observed, and it  propagates vegetatively. Fossilized leaves are dated as at least 43,600 years old, found in sediments with a maximum age of 130,000. |
| Pando | less than 14,000–80,000 | Quaking aspen Populus tremuloides | Fishlake National Forest, Utah | United States | Covers ۱۰۷ جریب فرنگی (۰٫۴۳ کیلومتر مربع) and has around 47,000 stems (aged up to 130 years), which continually die and are renewed by its roots. Is also the heaviest-known organism, weighing 6,000 tonnes. |
| Jurupa Oak | 13,000 | Palmer oak Quercus palmeri | Jurupa Mountains, California | United States | Quercus palmeri Engelm. = Quercus dunnii Kellogg. |
| Old Tjikko | 9,550 | Norway spruce Picea abies | Fulufjället National Park, Dalarna | Sweden | The tree's stems live no more than 600 years, but its root system's age was established using carbon dating and genetic matching. Elsewhere in the Fulu mountains, 20 spruces have been found older than 8,000 years. |
| Old Rasmus | 9,500 | Norway spruce Picea abies | Sonfjället, Härjedalen | Sweden |  |
| Mongarlowe mallee | 3,000–13,000 | Mongarlowe mallee Eucalyptus recurva | Mongarlowe, New South Wales | Australia | Alive.  A critically endangered species, known only from 6 wild individuals, first described in the 1980s.  Based on the size and growth rate of its lignotuber, the largest single specimen is estimated to be 3,000 years old.  However, it is possible that two other specimens are actually the result of a split in the original rootstock, and based on their spread of 26m would be estimated at 13,000 years old, potentially the oldest single tree on earth. |
| unknown | 3,000–10,000 | Huon pine Lagarostrobos franklinii | Mount Read, Tasmania | Australia | Several genetically identical males that have reproduced vegetatively. Although single trees in this stand may be around 3 to 4 thousand years old, the stand itself as a single organism has existed for 10,000 years. |
