Historic 200-year-old 'Treenis' landmark being chopped down

Scottish Forestry said the wood had reached the end of its life and was experiencing 'significant windblow'

A historic woodland that has caught the eye of travellers for more than a century is being chopped down.

The phallic landmark rises up a hillside south of Biggar, South Lanarkshire, and is visible from the M74.

Castle Crawford Wood has become known as the “Treenis” of “Penis Woods” because of its unusual form.

News of the plans to fell the forest that has stood proud for around 200 years has resurrected a petition to preserve it.

“These trees should be a protected landmark, as something of cultural significance,” one person wrote.

“This stretch of woodland is not only a memorable and wonderful landmark for those who have seen and visited it but holds so much life within that would otherwise be lost with its destruction,” another said.

A third fan wrote: “The world needs more whimsy. Save the Treenis!”

But despite the campaign, now backed by over 2,600 signatures, Scottish Forestry has approved the felling of the woodland, which is now in progress.

Castle Crawford Wood was originally planted in the 1800s, and features on maps dating back to 1849.

Scottish Forestry said the wood had reached “the end of its natural lifecycle” and is experiencing “significant windblow”, leaving many trees unstable.

The site has been felled and replanted several times throughout its history.

Scottish Forestry said it will be re-erected with a mix of tree species to help ensure a sustainable woodland long-term.
