I saw for myself the Hard Shield Fern Polystichum aculeatum at Cromwell Bottom LNR yesterday.
Yorkshire Naturalist Union had recorded here on their recent visit and I was unaware of it. It is a really rare fern in Calderdale, and it looks like this is a fairly new colony of about ten plants near the Hawthorn Alley growing in the fly-ash banking.
Later I was doing the recce for the walk to the former Halifax Zoo site to follow on from David Glover’s talk this Tuesday. There is a patch of the Winter Heliotrope Petasites fragrans just outside the boundary fence in the wood above the Elland Byepass. We used to call this Elland Wood Bottom when I lived in Siddal.
The only other record in Calderdale is at King Cross Cemetery, across the road from the Fire Station.
It is an invasive garden discard, and very extensive in some parts of the country.
David is a Courier columnist and his anecdotes will no doubt include the time one of the bears escaped into the woods.
