PICTURES: Ice petals flower in woodland at Hardcastle Crags, Yorkshire

Rangers and volunteers at Hardcastle Crags, west Yorkshire, were treated to a rare spectacle last week as ice “petals” covered branches in woodland on the National Trust estate.

Natalie Pownall, 25, National Trust Academy Ranger at Hardcastle Crags, said: “We were walking through the woodland at Hardcastle Crags with our conservation volunteer party, when we saw all these glittering white gems littered on the woodland floor. At first I thought they were fungi – but on closer inspection they turned out to be ice. 

“The ice formations are caused by water in the wood freezing. The water expands out of the logs, creating the beautiful ice ‘petals.’ 

“Most of these ice petals formed on the dead logs that we’ve left on the woodland floor after our woodland conservation work. One tree, which we felled last year, was covered in the ice fungi. Dead wood can also be an important habitat for invertebrates like beetles, birds and fungi. 

“You’ll often see these ice formations if the conditions have been below freezing and clear for a couple of days. Normally they melt away as soon as the sun comes up, but because our wooded valley is north facing and doesn’t get much sun we can enjoy the frost flowers all day long.”
