WFV June 17th 2025, Marsett Hill and Semerwater

Our last visit to this orchid rich site in Raydale was ten years ago. We took the Ribblesdale route which allowed for a toilet break at Horton-in-Ribblesdale. We returned via Bishopdale/Upper Wharfedale, stopping in Buckden for the toilets.

 As we journeyed through Settle the weather was closing in and we were soon driving through rain clouds. It did brighten as we reached the lower levels of Wensleydale but that changed again once we alighted from the minibus. As it was close to noon the decision was taken to have lunch before setting off onto the ridge. Four of us elected to stay in the bus whilst the other five preferred to picnic by the bridge over the beck.

The rain returned as we headed towards the nearby ridge but it was far too blustery for umbrellas so leggings and macs were the sensible choices. If only I had paid closer attention to the local forecast instead of being lulled by the national mini heat wave!

Very quickly we were finding lots of orchids on this cattle grazed steep hillside; Northern Marsh, Common Spotted, Twayblades & Heath Fragrants. A few Birds-eye Primroses also.  The rain did ease (at no time was it heavy) and after about an hour or so the group split into two; three members went in the bus to the north end of the lake and the others walked the two miles (it seemed longer?) towards Semerwater.

The paths were very easy to follow but did involve a number of stiles. Numerous wildflowers were recorded; Meadow,Wood & Hedge Cranesbills, Ragged Robin, Catsears, Valerian, Pignut & Eyebright. 

Curlews & Oystercatchers were very vocal & were seen all along the route. A singing Willow Warbler was observed on top of a bushy tree. No dragon/damselflies were seen. Lepidoptera was also sparse but nevertheless Red Admirals, Whites, Large Skipper. two Chimney Sweeper Moths & a Large Yellow Underwing were noticed. Several micro moths escaped identification!

Our two groups met up alongside the lake which contained lots of Canada Geese, Gulls, Oyster C’s & some Sandpipers.  Plenty of hirundines were in the air.   More Northern Marsh Orchids were growing close to the lake. Some had the look of hybrids & a very striking plant we later discovered was a recognised form of Northern Marsh var. atrata. Instead of the squiggles on the petals the central section was dark & the outside edges paler which made it look most distinctive.  

We departed at 16:10.   Kevin & Julia shared the driving duties.   John Gavaghan
