Autumn Crocus

Some pictures of a very interesting Calderdale speciality - the delicate Crocus nudiflorus - native to the Pyrenees but naturalised in our area perhaps since the Middle Ages. Taken today on the annual Halifax Scientific Society Autumn Crocus walk, led by Steve Blacksmith. A good year, with a host of over a thousand flowers seen in one of the traditional places, and a good day out as always.

Hedgehog records

I would welcome any records of Hedgehogs this year in Calderdale. They are really scarce in our area nowadays !
I already have  a few records in the database but unfortunately, all are road-kills other than one record so far of a living one - a juvenile near Roils Head.
I'm looking for location (street name), date and 'alive or dead'.
Please post any sightings on the blog, or in the comments box, or pass to Steve B who will forward the records on. Many thanks. Dave.

No food or shelter. The future is bleak.

Having just travelled through the East Riding, I find it not surprising that many bird species are in decline. There isn't any secret to it that needs the pretence of intensively written reports.

Mile after mile of farmland hedgerows were being tractor strimmed to neat garden-type hedges. All the growth that young birds would have just discovered to be 'home' was being hacked away. But worst of all was the squandering of the hawthorn berries and many, many elder fruits--rich black luscious hanging bunches. Now all gathering mud and squashed on the road.

White Beech

I noticed that a young Beech sapling in Centre Vale Park at Todmorden was looking white on its upper leaves. I thought it was mildew but took a closer look as I have never seen mildew on Beech.

What is actually happening is these upper leaves are totally devoid of chlorophyll, yet the lower leaves are as normal. No idea why this should be or whether it will persist on next year's growth.




         I have reduced the highlights in this image to try and get some detail in the leaf. you can just see there are some tiny eyelets of chlorophyll, yet the extension growth of the stem is vigorous.

Hi Everyone,

Please find attached the September issue of the YNU News Brief.  This month includes a feature article on Thistle Broomrape in Yorkshire written by Phillip Whelpdale; a fully referenced version will be available on the website shortly.  
There are still a few places available on the upcoming botanical training days at Three Hagges Wood-Meadow near York. The one day courses are suitable for professionals or amateurs, are reasonably priced at £40 per day and no prior knowledge is necessary. For more details, please visit the Three Hagges website: http://www.haggewoodstrust.org.uk/events/
Finally, the Freshwater Habitats Trust want to encourage as many people as possible to take part in the Clean Water for Wildlife Survey. Anyone and everyone can get involved, both groups and members of the public are welcome to participate. The two quick test kits, are easy to use and you can record the amount of nutrient pollution in your local ponds, streams, rivers, ditches and canals – and maybe discover new clean water sites. FHT will send you as many nitrate and phosphate kits as you need to take part. Each kit comes with a Clean Water leaflet and recording form, so that you know what to do and what to record. More information can be found on our website  https://freshwaterhabitats.org.uk/projects/clean-water/take-part/ or contact Laura Quinlan lquinlan@freshwaterhabitats.org.uk
If you would like to contribute a feature article highlighting the work being done in our region or species of interest, or if you have any news or events you would like to include in the next News Brief, please e-mail comms@ynu.org.uk

Hollas Lane walk - Sept. 2nd

Blessed with fantastic weather the turn out was good - around a dozen people showed up. Peachysteve lead the walk and his local plant knowledge and ID skills are something to behold! There were a sprinkling of knowledgeable plant folk who I'm sure left the walk having seen new plant or fern species. From a lepidopterist's point of view it was a worthwhile trip becoming familiar with a range of plants that moth larvae use such as Grey Alder, Sneezewort and the goosefoot/orache family.




BIRDS: Kingfisher and Grey Heron on the river with Pied Wagtail, Nutchatch and Great Spotted Woodpecker all heard.




SPIDERS: I took a couple of shots of "interesting" looking arachnids - maybe Bruce or Julian can enlighten us? Their bodies were small pea sized.





LEPIDOPTERA:
Quite a few Red Admirals using the numerous Buddleia bushes on site.

A new one for me was this Coleophora argentula case on a Yarrow seedhead. After taking it home for further study I was surprised to find it was tenanted, the larva is now happily feeding away on the seeds. It will "hibernate" over winter to resume feeding in the spring. The adults emerge in early summer.
A leaf mine found on Downy Birch was Stigmella confusella. The frass (caterpillar poo) line is black and narrow throughout the mine which helps ID this species. The mine is complete and the larva will have exited it a month or two ago and have dropped to the ground to pupate.

Oak Trees

Acute Oak Decline and Chronic Oak Decline are terms used for the large numbers of older trees (above 50 years) which are showing signs of dieback and stress. AOD is affecting increasing numbers of Oaks each year and can kill the tree within 5 years. This blog does not all copying. Go to Google either of those diseases there is plenty of info there.

The affected trees are mainly in the eastern counties, midlands and south of England. There has been much research on the causes but recent work has suggested AOD and COD are the same disease at different stages of the spectrum. There was a theory that the Agrilus Beetle was part of the problem but it is more likely the beetle activity is taking advantage of already weakened Oak stems.

More recent research is looking at the soil environment and there has been found a strong link between high Nitrogen levels (from farming/air pollution/car exhausts) in the soil and the mapped trees that are showing symptoms of the disease.

What may be happening is the altered soils are affecting the essential link between mycorrhiza fungi and the roots of Oak trees. The roots need the fungal association to help with water uptake. When this link is severed, then the trees die from lack of water, particularly in the already drier parts of the country such as East and South. 

There is a worry that essential fungi are dying and soils generally are being degraded.



Norland moor walk - Aug.23rd

I won't give a summary of the walk as others are better qualified for that, suffice to say there was a good turn out of fifteen people and a couple of dogs and the weather was great after an ominous start to the day.


Lepidoptera as follows:


As is usual on the higher part of the moor micro moths were few and far between, in fact I only saw three all day but two of those were new to me :-)






No Annie, it wasn't a White-streaked Badger Moth but Eupoecilia angustana. It's larvae feed on the flowers and seeds of Heather amongst other plants.


This was in the grass at the base of an isolated birch tree - Epinotia trigonella. It's larvae feed on the spun leaves of birch. At 10mm in length it's nearly twice the size of the previous species. This one brings my list of Lepidoptera seen in Calderdale to 499.......

The third micro was a Agapeta hamana lying face down in a puddle!

Lots of leaf mines and coleophora cases seen but I'll not trouble you with a list of meaningless latin names.

Other leps were:

Silver Y x 3 flying wildly after been disturbed
Peacock sunning itself on Heather
Small White x 1
One Buff-tip larva doing well to avoid being trampled or run over in the car park.

Also of interest was this Cowberry plant hosting the fungi - Cowberry Redleaf (Exobasidium vaccinii). It deforms the upperside of the leaf turning it a reddish colour and the underside is covered in a white spore-bearing powder. I don't think this is the usual rust or smut but more closely related to the jelly fungi, sharing the same phylum.

Help plant 3000 Autumn Hawkbit plug plants to provide food for Twite!



Volunteers needed!  Please see below the note from Katie Aspin of the RSPB:

As you may be aware, the Twite Recovery Project has been working with farmers to increase food availability for Twite during the breeding season, mainly through restoring hay meadows with key Twite food plants including Dandelion, Common Sorrel and Autumn Hawkbit.  Autumn Hawkbit is an important food source for Twite late in the breeding season, however, botanical surveys last year showed that this species hasn’t taken particularly well in some of the reseeded meadows.  Natural England have therefore approved a grant to buy some Autumn Hawkbit plug plants, which we hope will do better than the seed.  We are looking for volunteers to help us to plant these plug plants in September at farms near to Ripponden, Rishworth and Marsden.  If anyone would like to help out, please let me know which dates you could make from the list below:

Monday 18th September
Tuesday 19th September
Monday 25th September
Tuesday 26th September

Any time you could give would be very much appreciated, we have over 3000 plug plants to plant!

Many thanks,
Katie Aspin

Change of Plan

At the monthly meeting last night when we were treated to Philip Marshall's excellent talk on historic trees I announced in the second part of the meeting that there was to be a walk to Howarth from Mount Tabor on Friday 11th August, (returning by bus we had planned.)

Unfortunately I had forgotten it is the Cromwell Bottom Open Day on Sat.12th, where we are due to have a stall. Due to this I will have to postpone this walk. (See the link to the Cromwell Bottom Wildlife Group on this blog.)

It is an impromptu walk ( not in the programme.) Some of us want to to commemorate the book "A Spring-time Saunter" by Whiteley Turner about a four-day walk he did in 1904. We were prompted by the upcoming talk "Uncovering Bronte Country" which we are hosting on September 12th.

I will obviously go to the meeting-point to check if anyone turns up.
Yesterday morning (Tuesday August 8th) I found this beautiful creature almost drowning on the metal walkway outside our building. Unable to identify it, I sent the photo to our very own Moth expert, Charlie Streets. For those people at last night's meeting who also didn't recognise it, Charlie has identified it as a Lesser Swallow Prominent (Pheosia gnoma), showing the chocolate brown head and thorax typical of the Northern form (apparently!). Charlie also supplied this useful link:

Weeping Beech

For those who were enquiring at yesterday evening's talk where this magnificent weeping beech is growing; it is in the local park at Evesham in Worcestershire. I have never seen a better specimen.


                                                     Beech in Evesham Local Park


If anyone wishes to visit this 1,000 year old Oak, which has a girth of 9.08 metres, it is at Ripley Park in Yorkshire. Originally it would have stood within the Forest of Knaresborough. But this was not a Forest of trees as we understand the term.
