National Trust meadow seed for sale


This is a message from Natalie of the National Trust:

We were able to brush harvest meadow seed this year!
We a few bags left for sale from this year’s mini hoard – £35 per Kg.
It might be a bit late now to sow this autumn due to the heavy frosts we have been having – but I may be a little pessimistic.
The seed will be great for spring sowing, however the yellow rattle seed would have just expired.
If you know of anyone who would like to turn their garden into a meadow please send them my way!

All the best,
Natalie

Interesting fact

Trees are big and tough because more than 95% of their cells are dead. That's remarkable!

November's Indoor meeting


After the AGM and the Recorders Reports there will be a dvd called "A Bird for all Seasons" made by one of our Life Members, Gordon Yates. I think it is one of his best, and not ALL about birds. Members and visitors who want to chat instead of watching the video are invited to do this in the back half of the room.

Society Walk to Lydgate; some history notes

Adding to Steve's account of this walk, I have gleaned some info from 'Flora of Todmorden' published 1911. This flora was compiled decades after the deaths of Stansfield and Nowell, from records gathered by them in the early to mid 19thC.

But before I go on and in case the following article is not of interest, can I arrest your attention by mentioning a reference to a book by Mr. Stackhouse -- Map of Rocks published 1831, in which there are large lithographs and descriptions of many of the major named Rocks in the valley. I can find no reference to this book anywhere and I have searched the internet. If anyone has any knowledge of it I would love to hear.

For the aficionados; please read-on

The Flora of Tod states there is a calcareous grit outcrop in Harley Wood Scout (near to our walk) and "This stratum arrested our attention many years ago, in consequence of finding several calcareous plants growing upon it. These were Wall Rue, Maiden Hair Spleenwort, Carline Thistle and Wood Melic and some others" (pity they weren't listed). (I have never seen Wood Melic in that area).

On our walk it was mentioned that Frank Murgatroyd had a record for a Filmy Fern; but it seems no one had ever found it and doubts was expressed about the suitability of the habitat where Frank said it was.

I wonder if he was bringing to mind this early record from the Flora of Todmorden where there is a record of Tunbridge filmy-fern being common above Springs at Harley Wood (Lydgate). The book goes on to say this filmy fern was destroyed by the getting of stones for building the Burnley Railway (built in 1840's). Maybe Frank was passing on this record and perpetuating the plants existence? Although the site he mentioned was not near the stone quarry. Perhaps not all plants were destroyed? "The gametophyte is likely to be inconspicuous with a narrow ribbon-like thallus" --Wikipedia.

The walk went past the Orchan rocks. The Flora of Tod gives this info "We come now to the Orken, or Orchan stone: or as spelt in a deed of 1491 Ork-ndstone. The name as pronounced by the inhabitants is none other than the Gaelic word meaning incantation; or in the Irish dialect of the Celtic, 'Orcain', a murder or killing. In the ordnance survey the word is spelt Hearkenstone but we apprehend this is wrong. Though the name is applied to the whole group of rocks, the real Orchan Stone is the large, square, isolated block which stands nearly in situ, whilst the others around it have been tumbled down in the utmost confusion. The stratum a few yards to the north of the Orchan Stone, remains in situ and has only been disturbed here and there."

"Some years ago a number of masons and quarrymen laid siege to this fine mass of rocks, and it was at our earnest request , and from the good sense of the proprietor (the amiable T. Ramsbotham) that this piece of reckless destruction was prevented."

Mr, Stansfield also refers to ludicrous names given to these stones in the "History of the Parish of Halifax". Mr. Stansfield has the riposte "His informant must have been some ignoramus of the lowest grade, totally unfamiliar with the district".  (Todmordians have always been expressive in their opinions)!!

Society Walk - Todmorden Walk Sat 27th October

The Autumn colour and woodland fungi walk went really well considering the dire warnings from the BBC of cold weather arriving. It should be  "The North Wind doth blow and we shall have sun" (NOT snow - or rarely.)

Fifteen people and two dogs turned up; we were pleased to welcome two ladies from Hebden Bridge with their dog Bibo, who were very welcome, and as usual Peachysteve's Meg accompanied us.

The mood was light-hearted as we set off, despite the early parts being steeply uphill. The views were amazing, and the Autumn colours rich and satisfying.

At Orchan Rocks we had the spectacle of approx 800 Pink-footed Geese going over in several skeins. The sight and sound was impressive, especially for those who had not seen wild geese migrating before.

We found fewer woodland fungi than hoped for, a single Elfin Saddle being a notable exception, but on the sheep pastures higher up there were interesting species of waxcap, and a group of Caterpillar Clubs, each one attached to an underground moth larva, as we proved by digging one up (and replanting.),

Other birds seen were large flocks of Fieldfares "chack-chacking" as they went over.

After the walk, five of us went  to Jerusalem Farm in Luddenden Dean, to check for fungi, including the rare Date-coloured Waxcap which I once found on a HSS/ Mid Pennine Fungus Group foray, (I was ignorant of its identity and  rarity) but we were unlucky, but did find the fragrant Cedar Waxcap, which smells like pencil sharpenings.

Gosport Clough photos - Oct. 20th

The walk was very well attended and led by Peachy Steve whose knowledge and enthusiasm is infectious and inspiring in equal measure.

Despite it not being a classic year for fungi so far a very long list was racked up and recorded for the relevant organisations. My FUNGI highlight was this Spangle Waxcap in appropriate autumn colours.

I tend to only photography fungi new to myself rather than the more showy ones, a point well illustrated here with these Ugly Milkcaps - note the bruised gills dripping with milk.

I was surprised to find I hadn't recorded these Petticoat Mottlegills before either. The veil remnants on the cap edge being the "petticoat".

This is one of three Scarlet Caterpillar Clubs we found. I couldn't resist excavating it to find the host just below ground level - a moth larva.

And the dissected larva full of mycelium.

And anyone who knows me will know that this was my highlight of the trip - a Barred Sallow resting by day, appropriated enough on a Beech leaf - it's foodplant. One of a group of autumn species well marked to blend in with fallen leaves.

Invitation to October 27th Walk - Report on the recce we did today : Autumn colour and woodland fungi in the Harley Wood area of Todmorden


 Hopefully it will be dull, calm and misty. This is when the Autumn colours really smoulder and look so fabulous; far preferable to bright and garish  New England !


All these images taken on the way back downhill. On the way up we pass the Orchan Rocks. There are some longish steep lanes to get up there, but we will go at the speed of the slowest.


To my eyes the most scenic area of Calderdale; deep drops and spectacular but uncrowded tree views


Our route is on safe footpaths all the way, but a little nimbleness may be needed on some rocky downhill paths


From Lydgate on the Burnley Rd we go up as far as Hartley Royd on the Todmorden Centenary Way, then back down a different route.


Our phones told us we walked about 4 km, but I don't know if this allows for the  undulations.
We should be back by 3.30pm easily.


We sat under beech trees to eat our picnic when the drizzle threatened to penetrate. Lovely real outdoor weather!         Birds seen included Kestrel, Goldcrest, Fieldfare, Brambling (1).
Meet 10.30 at Lydgate Post Office (beyond Centre Vale Park, just after a car wash.) Park on Church Street, or on Burnley Rd.
If coming by bus I'll meet you at the fish shop just over the river bridge at Tod Bus Station. Let me know what time your bus gets in. Two spare seats at the moment. 0771 500 5379

Bradley Wood

I was given a splendid tour of Bradley Wood by Mick Harrop. It is ancient woodland containing bell pits showing a former use by digging for coal.

The woodland is an interesting mix of tree species as a result of planting over recent decades by the Scout Camp and Activity Centre. But when you filter these out an older landscape emerges, which includes large Hazel coppice stools and many fine Oaks.

One of my photos is of a Beech which is large in both height and girth and looking remarkably healthy. It could easily be 200 year old, an age which is rare for this species in our area. Notice the graffiti carved in the bark high up the trunk.

A most intriguing tree is a large multi-stemmed Oak growing from an old coppice stool. Just how old is it? Looking at the width of the base and how it could have spread outwards with each coppice cycle is it fanciful to think in terms of 400 years old?

There are also some American Red Oaks (Quercus rubra), with leaves showing the natural variation in shape which caused me confusion when trying to identify them.

Before we went to Bradley Wood, Mick showed me an Oak in the middle of a field near Warley Town. It is the kind of tree that stands out in the landscape; with its spreading branches being evidence for it always having been an open grown tree.

To keep this Oak from losing its character and help it live longer, it is important not to let it become part of a woodland. If pollards were created from the young Oaks nearby---their present branch structure being ideal for doing this---both young and old would benefit. The many burrs contain dormant buds, which are just waiting for the right conditions to enable new shoots to grow. This is an Ancient Tree of the future.

Larinioides cornutus, Bradshaw

Lovely to find this female Larioides cornutus near Bradshaw Lane this Sunday, shown roused from its weather-proof 'silken retreat' by a gentle poke from a pen nib.

The retreat is closely woven with an entrance near the bottom.

A smaller spider is using the same dried stem, probably a Dictyna which tend to haunt the dead heads of plants
Both common species but amazing beasts. The cornutus often live near water, sometimes climbing beneath the water surface to escape danger.



October's Talk on 9th. Please note this replaces the Geology talk from Will Varley in our printed programme and elsewhere on this site. (Due to an error on my part.) SB



If you are a gardener you will be perhaps taking stock on how well it did this year. This talk will help you to make decisions to improve your plantings if they could be better for the bees and other nectar-loving insects next spring and summer.

At Blake Dean


Very impressive Beech and measured round the girth gives a possible 200 year old tree. The whole group of trees here is very attractive and the sheltered position will have helped them grow. I wonder who planted them.

On the other side of the little footbridge there are a few isolated trees; the illustrated Oak is difficult to age but has character. The bulge at the base is probably decades of adventitious buds trying to grow but constantly eaten by sheep. It produces a complex pattern of cell growth distinct from the normal tissue.
                                              
                                                 Hmmm; I wouldn't stand there too long.



                                                             That branch is remarkable


                                                               Characterful Oak

Hardcastle Crags fungi

Seen near Gibson mill on discarded remains of a pine footbridge. Peachy Steve has helped by suggesting it could be Antrodia xantha. There is a record of this a couple of years ago in the same area, possibly the same piece of wood!

Very attractive fungi and with imagination has a Mount Rushmore head on the left, possibly Theodore Roosevelt.

Hardcastle Crags and Beech

The National Trust has a woodland management plan for the Crags which is available to view by searching --   forestplans.co.uk and entering Hardcastle Crags in search box.

I was surprised to see that extensive work on the Beech trees has already begun within the last week or two. Quite a number of selected mature trees have had all the crown removed and a chainsaw version of ring barking to the lower trunk. The reason for leaving them like this is to provide standing dead wood. They will not recover; unlike Oak or Ash treated in this way would probably survive and some would thrive.

So far the older ones have been left alone and I do hope they are allowed to remain.

The tree works are taking place above Gibson Mill, near the 2 footbridges upstream; on left banking looking upstream.

There will be replanting but I do hope the numbers aren't excessive; it is the spaces between trees that make for a functioning woodland. A good experiment would be to leave an area to seed itself and compare it with an adjacent one that is planted.

Beech is a bit of a nuisance in the wrong place or in excessive numbers but there is no doubt it makes an impressive tree. We are seeing the last of the big Beech trees in the Calder Valley; photograph them whilst you can. The massive one at the junction of Mytholm steeps and the main road, just opposite the turning circle at Hebden Bridge, has been condemned and will soon be gone.

                                   


                                     Many in this area have had all the upper crown remove
                                       
                                   

                                               Ring barking as well as crown removal

                                                 More sunlight as crowns are removed

                                                                Tops taken out

Field Bird's Nest fungi



These have been present on my allotment for the past month or so, I thought they were just stunted, de-hydrated mushrooms up until today when I had a closer look a look at them. They range from around 6-11mm in diameter and are easily overlooked so I was pleased to have given them a second glance.

I think they are Field Bird's Nest fungi (Cyathus olla), judging by their size and trumpet shaped cups when mature. They have 3-5 eggs inside.


If anyone wants a look at them drop me a line - they're at Skircoat Green allotments.

Plant battle

Pendulous sedge (left) 'muscling in' on Woodrush

Portia is wondering if anyone else has noticed the effect of increased amounts of Pendulous sedge locally, muscling in on Woodrush in damp woodland. An area near her in Todmorden has no Woodrush left as a result.

Fig plant

Growing from the river wall in Todmorden is this Fig plant. It will be a Ficus but what species I don't know. Is wild Fig unusual in Calderdale---there is a colony of it in Sheffield.

Hares, Short-eared owls, Twite and more...


The rather dismal, rainy start to Sunday September 16th culminated in a glorious evening while we were walking the area round Gorple reservoir. We were treated to the sight of  Short-eared owls (we counted four in total), which circled above fields of hares (at least 6!), rabbits, pheasant and grouse. Driving back along Edge Lane, we were lucky enough to see a flock of perhaps 20 Twite which landed briefly on a disused Delph. More about that later from Steve Blacksmith. For me, the joint highlights were the hares - I have never seen so many all in one go! - and the sight of those magnificent owls, their wings flashing a pure, bright white in the afternoon sun.

Autumn Crocus, a quick visit.

The number of the Autumn crocus, Crocus nudiflorus, blossoms in St John's graveyard at Bradshaw is 129. This one of my best totals for this site. The hot dry summer has not had any visible effect on these plants.



                  _______________________________________




Update:
That's excellent Bruce, thanks for checking.

If anyone wants to see them, they are on the downhill side of Bradshaw Churchyard, along the perimeter wall under a row of trees.

TOUR OF SITES Sat 22nd September


There's an Autumn Crocus trip, consisting of short walks to see them along the riverbanks with short drives between, in the Copley and Ryburn Valleys on 22nd September. Meet PS and SB at Hollas Lane, Copley at 10.30am HX3 0UW.  If you are with us all day, bring a packed lunch.                                            (Report of the walk below)

This was taken last year of the colony at Strines Beck, Bradshaw/Holdsworth,  by Annie Honjo.  Julian Birkhead another of our members is in the picture.




Report of the Walk on 22nd September: Ten members attended plus two dogs.
We first went to the colony on the left bank of the Calder, near the junior rugby pitches at Copley. I was surprised to be shown by Peachysteve several odd crocuses and one clump actually on the playing fields! Those on the riverbank under the young oaks were blooming, but somewhat flattened by last week's wind and rain.

Secondly we went to the right bank of the Calder opposite the above spot, where Peachysteve recently found several patches of the leaves in spring. These also were flowering, but sparsely, showing it's much better to survey the extent of the colonies in spring, when the foliage comes up.

Next we drove along to Kebroyd and looked at the colony at Grassy bottom, by the weir, on the left bank of the Ryburn, among the beeches. Again there wasn't a great show, but the site is intact. There were some convenient fallen trunks here so we sat and had our packed lunches.

We made our way back up to the Oldham Rd through Ripponden via the football pitch and explored up Ryburn Lane, where all but Peachysteve had never been before. At the top, just after it ceases being a tarmac lane and changes to a bridleway, Peachysteve wanted to show us an immense oak, approximately 5ft diameter in its short trunk, with several large ascending smaller trunks. Philip Marshall thinks it is possibly the oldest oak in Calderdale. The "Ryburn Lane Oak" we decided it should be known as, and that it is imperative that it should be recorded and carefully protected.

After that we walked back to Grassy Bottom, via a single crocus at a small colony on the grass verge outside 112 Oldham Rd.,  to the Old Parade Ground, now overgrown with youngish trees, where there is another Crocus colony on the left river bank approximately 60 paces down stream from the footbridge. We confirmed that it is still there and saw a few bedraggled blooms.

Finally we all shared cars up to Dean Lane at Sowerby to see the colony in the field there, not far from Ryburn High School playing fields. These were the only undamaged blooms, and showed a large swathe of purple among the grass.

Other notable wildlife were a Little Egret at Hollas Bridge on the Calder, a beautiful white tufted caterpillar at Grassy Bottom, black in between a few segments, and with a pastel pink appendage sticking up near the rear, now identified on www.wildlifeinsight.com as  

Pale Tussock Moth (Calliteara pudibunda)

 and a Hedgehog, sadly a fatality on the main road at Kebroyd.   Also a single plant of Rustyback Fern on a garden wall along the main road, the only one known of for miles, and fungi were coming up in quantity and variety. The Ryburn Lane Oak had a huge, dripping beefsteak fungus on it, as well as an Artists Bracket.

Unusual Grass species

I looked at the Incredible Edible raised beds in Todmorden railway station car park. There was some Sweetcorn but then a tall annual grass at the front looked of more interest. It was Cockspur grass, Echinochloa crus-galli, which flowers very late in the season and often in October.

The last time I saw it was Todmorden park in October 2010, a large stand of it occupying the lake of flood water. Cockspur originates from tropical Asia and Africa; in the paddy fields of the far east it is a real pest.

Cockspur grass is considered one of the world's worst weeds and can remove as much as 80% of the available soil nitrogen. Accidently introduced to many countries where it has become invasive but in the Calder Valley is rarely seen

Some varieties of Cockspur are grown for their edible seeds and young shoots, so it would be interesting to know whether Incredible Edible knowingly planted this grass or if it just 'popped up'.

UPDATE: Incredible Edible have said they didn't plant it. Good record then for this casual. It probably won't appear next year, so see it while you can if passing that way.
