Of the 51 giant redwoods Redwood World measured in Westonbirt's Old Arboretum in 2010, this one had the thickest waist. Its trunk was 7.01 metres round at chest height, wider than the famous pair at the old gateway and wider than the 42-metre layered tree about 60 metres to the north-east. It is not the tallest. At 34.2 metres it stood eight metres below the layered tree in that survey, a redwood that has put its growth into girth rather than height. The arboretum tracks it as tag 02.0142, and the measurements come from a single independent survey taken in September 2010, so the girth today will be somewhat larger. The planting date is the open question. No source we have found says when it went in, and we would rather leave the age blank than guess one from its neighbours. If you have the arboretum's planting record for this tree, tell us. It makes a good last stop after the layered copse. Walk the 60 metres between them and you have seen a 42-metre redwood and the stoutest one Redwood World recorded here within a few minutes of each other.
