50 years to the day we met for a ramble in Sleightholmedale. 20 members and guests met on The Avenue. We do not know the exact route taken in 1964; in 2014 we enjoyed a ramble through the woods down into the valley and then walked through the flower-rich water meadows upstream along the river. I suspect the earlier trip may have gone further upstream or visited the other side of the valley, since we did not pass any habitat suitable for bog asphodel or cottongrass. Some of us braved the swinging Nepalese bridge over the river.The 1964 plant list was short, clearly only recording interesting species. I am very suspicious of the frog orchid (there is only one other old local record that I know of, and no recetn ones. The way it is phrased I think there was uncertainly of hte identity of whatever was found, and I wonder if it might have been a twayblade perhpas with damaged leaves.
Of the plants on the list only the columbine (leaves only), spindle, cow wheat (only one plant) and fly orchid (almost over) were found. There had been several spikes of fly orchid seen a few weeks earlier, but only one remained, in deep shade in an old quarry. This may indicate the effects of global warming if there were more fly orchids 50 years ago, or perhaps they also only found late specimens.
In keeping with the 1964 list I only recorded a few species of particular interest. The Herb Paris was in fruit, so we could see the shiny black berries which iwas interesting as we usually see this plant earlier in the season with its extraordinary 4-way flowers. I was sorry not to find the butterfly orchid (although at this date I would expect it to be over and therefore hard to spot!), pyramidal orchid or the chickweed wintergreen. We only found a single plant of cow wheat this seems to be scarce throughout Ryedale and declining, although we do not know why.
In the waterside meadows we saw several butterflies and moths, including a ringlet butterfly and a magnificent green caterpillar (subsequently identified as a Copper Underwing moth (Amphipyra pyramidea).
