Butterflies Still Tumbling

Wall Brown - Nigel HeptinstallWall Butterfly

You may well have noticed the national news, “Butterflies crash in fourth worst year on record in 2016.” It makes worrying and uneasy reading. Butterfly Conservation tells us some 40 of the 57 species studied recorded a decline compared with 2015, many of those species suffering are inevitably the rarest species and ones we aren’t often privileged to see, especially locally. One species which is suffering and can, or perhaps was, seen locally is the wall butterfly which is widespread but rapidly declining; it is a UK Biodiversity Action Plan (BAP) Priority Species. I don’t recall seeing one last year and I always keep an eye open for butterflies. It’s not however only the rare species that are suffering, our more common and most welcome species are also in decline. The Gatekeeper is down 48% and Meadow Brown falling by 31% compared with 2015. It’s not all bad news, however; the widespread and migratory Red Admiral recorded a rise of 86% compared to 2015, but beware don’t forget 2015 was a really bad year as well. It’s a bit like a 1% pay rise for low paid workers, a little bit of nothing is bugger all.

Red Admiral - Nigel HeptinstallRed Admiral

Local Butterfly Situation

Paul Millard is the butterfly recorder for this area of Yorkshire. He has kindly given me permission to reuse his local butterfly news. The first snippet of interest is that a “Red Admiral was seen on 25 March at Ainderby Steeple, this is so early that it could easily have been an overwintering adult. It is only a few years ago that it became accepted that Red Admirals overwintered in southern England.” Another sign of global warming? Paul tells us, “The list of butterflies flying now has expanded, it also includes; Small Tortoiseshell, Comma, Peacock and Brimstone. They all share the same habit of hibernating in the adult stage. I have also had reports of Holly Blue, Orange Tip, and Green-veined White.” So weather permitting some butterflies are flying earlier, that creates problems because they need access to food and are appropriate plants always available? Not necessarily.

NO RECORDS

These records need to be taken in the knowledge that folk are now using mobile phone apps and similar to record their sightings and the improved numbers seen last year may reflect an increase in recorder activity. Interestingly Paul tells us, “The Small Tortoiseshell is a cause for concern as the numbers are trending downward again, however they are flying again now as they emerge from hibernation after a less challenging winter. Recent research has confirmed what we always suspected, that butterflies in general do better the year after a cold hard winter. Last winter was hardly that but at least it was not so wet.”

Please Help

My experience, which unlike Paul’s has no scientific basis, is that with the probable exception of brimstone all butterflies did very poorly last year. Cold wet summers don’t help butterflies and when we did start to see butterflies in autumn food plants were again scarce, so you can help and here’s how.

  1. Join Butterfly Conservation.

  2. Donate. In the UK we have lost 25% of our widespread butterflies in just 40 years. Iconic species are struggling to survive.

  3. Identify a butterfly.

  4. Report your sighting, get the Big Butterfly Count App. It’s fun and easy to use and helps you identify the butterflies. It’s also free.

  5. Make your Garden Wildlife Friendly. Remember butterflies and most wildlife need a source of food and places to nest all summer. The fields are full of pesticides, make sure your garden helps wildlife.

Spring Hots Up

Comma - Roger LittonComma – Roger Litton

Peter Durkin reports “whilst working on Quarry Moor Lane, Ripon on Wednesday, 22 March a flock of redwings about 200 flew over at a height l have never seen them fly before heading north. Today, Thursday, a swallow came by heading same way.” When did you see your first swallow of the summer? Indeed have you seen one at all this year yet?

John Stockill writesSince being off work due to an operation my wife and I have been enjoying the lovely weather and taken full advantage and walked nearly every day visiting Whitby at low tide, the Farndale daffodils, a scorching Scarborough and a raging Janet’s Foss at Malham and best of all being a loyal ‘Cragrat’ Knaresborough. It reminds me that in a modern technology fuelled world that a good pair of walking boots and a packed lunch which costs next t’nowt the British countryside is all ours to explore and enjoy. Here are a few pictures of our treks including a comma butterfly. You can’t disagree with that and John was also lucky to see a comma butterfly, see the above.

What signs of spring have you seen?

Tree Aftercare Event

What, I asked myself, is a Tree After Care Event? Well it’s an opportunity to come and help The Friends of Jacob Smith Park clear the ground around the park’s young trees. This enables the roots to receive more nutrients, meaning the trees can grow nice and strong. Everyone is welcome! So have some fun together whilst caring for the park. You’ll need suitable footwear, your waterproofs and a pair of gardening gloves. Please also bring forks and spades. Come for as long as you can! Meet at the noticeboard, main entrance, 10am Sunday, 30 April. Email Jo at Jacob.smith.park@gmail.com if you need more info or visit the website. It’s free, it’s outdoors, what else do you want?

Rossett Nature Reserve

If like Roger Litton you went to Rossett Nature Reserve and was a little horrified with what you found, cleared ponds, all the vegetation stripped away and completely bare ponds, then don’t worry. It has all had to be done. Sam Walker from the Council explains, “There has been an intensive programme of work at Rossett over the last 15 months so that it was necessary to bring the site up to scratch. This work has included a new dipping platform, noticeboard, footpath improvements, litter picks and a variety of habitat enhancements. The major work carried out this winter was a programme to clear the ponds of Crassula Helmsii – an invasive non-native species that was choking the ponds and limiting them as a suitable habitat for the Great Crested Newts (GCN). In fact it had reached the point where you could walk across a number of the ponds on a Crassula carpet! For a number of years the friends group and HBC had been carrying out this work manually but the impact we could have was limited. It was decided that the best way to ensure the continued suitability of the site for Great Crested Newts was to bring a digger on site to clear the ponds. This work was all agreed with the Harrogate Borough Council’s ecologist and we ensured that the work was done in January when the newts wouldn’t be in the ponds. This work was always going to have a significant initial impact as you can’t just selectively remove the crassula. However, over time, the site will make a full and complete recovery. The works have certainly had the desired effect and the ponds are now suitable for breeding Great Crested Newts. In fact we have already had reports of both Great Crested Newts and Smooth Newts in the ponds already this year. The vegetation will of course grow back, especially now that it’s starting to warm up. The Crassula will return as it is impossible to eradicate. I would anticipate we would have to do something similar again in the next 5-10 years. These works are essential to ensure we maintain a network of ponds suitable for breeding Great Crested Newts.”

Red Line Against Fracking

Frack Free Ryedale has sent out an appeal for knitted/crocheted 15cm red squares, to be sent to them by the end of May. These will be stitched together by the Frack Free Yarnbombers to make a RED LINE AGAINST FRACKING. In a joint project with fellow activists in Portugal and Germany the piece will be displayed on 11 June, before travelling to Bonn for the COP23 conference in November; a literal representation of the flourishing campaign for a clean energy future. If you complete any squares than let Janice Scott know email timscot@hotmail.com and she will collect them and pass them on.
