There are several theories as to how it became so huge and oddly shaped.[citation needed] The Major Oak may be several trees that fused together as saplings, or the tree could have been pollarded. (Pollarding is a system of tree management that enabled foresters to grow more than one crop of timber from a tree, causing the trunk to grow large and thick.) However, there is only limited evidence for this theory as none of the other trees in the surrounding area were pollarded.[citation needed]
This enormous tree is commonly thought to be the UK's second-largest oak tree, only truly surpassed by the gigantic Majesty Oak near Dover.[6]
History
Support chains were first fitted to the tree in 1908, and its massive limbs have been partially supported by an elaborate system of scaffolding since the 1970s.[7] In 1974, fences were installed around the tree to protect it from root damage, since the number of visitors to the tree was compacting the soil around it.[8]
In a 2002 survey, it was voted "Britain's favourite tree".[9]
Also in 2002, a person illegally attempted to sell acorns claimed to be from the Major Oak on an internet-based auction website.[10]
In 2003, in Dorset a plantation was started of 260 saplings grown from acorns of the Major Oak.[5] The purpose was to provide publicity for an internet-based study of the Major Oak, its history, photographic record, variation in size and leafing of the saplings, comparison of their DNA, and an eventual public amenity.[11]
