Significant because of its age? Sure. Significant because of its tenuous ties to Darwin? Someone named it Darwin's Oak a couple years ago to gather public sympathy against the project. You could argue against any development in the area because "Darwin may have walked on these grounds and threw rocks in this stream as a child".
Yeah I'm all for keeping old trees like this one but that's because old trees are good in and of themselves. I care less about Darwin possibly having climbed it 200 years ago and more about little boys and girls climbing it 200 years from now. Nobody will be driving on that bypass in 200 years but I do hope that children will still be climbing trees like this one.
Does it, though? I see a perfectly good railroad, as well as National Cycle Route 81, running right through town. So WTF does anybody need a bypass for?
The reason behind building around the farm seems to be something quite practical:
“The myth was somewhat debunked last year when a recently unearthed documentary revealed that a geological fault, rather than an awkward farmer, was the real reason for Stott Hall, which lies west of Huddersfield, in West Yorkshire, being left in that peculiar location.”
Yeah this is true. In that case they had to build around the farm.
But, in the case of the tree, are they choosing not to build around the tree because the land either side of the tree is unsuitable to build a road on or because it's cheaper just to plough through the tree? I wouldn't know... but it makes me wonder.
