July 2nd walk to Middlefold (Hill Farm Garden and Hay Meadow) Colden

Halifax Scientific Society walk, Saturday 2^nd July: Middlefold

A walk and visit to a garden, wild flower meadow and wildlife haven created at 1000ft in Colden

Please meet outside the New Delight Inn, Jack Bridge, Blackshaw Head, Hebden Bridge, HX7 7HT.   There is roadside parking, but please make sure that your cars are not causing an obstruction on this twisty road, and are not in the New Delight’s car park!

We will be walking up to Middlefold, home of Jim and Elaine, which will take approx. 40 minutes.  For those who are fascinated by historical architecture, we will pass spots of great interest.   We will be shown round the extensive garden they have created, including the vegetable garden,  woodland area and the hay meadow, which will take approx. an hour.

The return journey is via a different, longer route and can, if desired, take in the 6 acre upland garden of Land Farm, Edge Lane, Colden (www.landfarmgardens.co.uk), one of the National Gardens Scheme’s Yorkshire gardens, which is dog friendly, offers teas and charges an admission charge.  Alternatively, folk can return by the same path we took at the beginning.

Please note:

Depending on which route you wish to take, this walk will take anything from 3 hours to much longer.

·         No dogs in Middlefold gardens and meadow please

·         Children welcome

·         Bring a packed lunch/drink etc.

·         The New Delight will be open if you’d like to have a drink at the end of the walk!

A trio of rare Grasses and a lost Rock Outcrop

Walking in Hardcastle Crags on Saturday we were admiring the hazy effect of hundreds of Wood Melick flower heads, on the track side just above Gibson Mill. This is a fairly widespread grass in Calderdale.

I mentioned the much rarer Mountain Melick that we had been unable to find at Hardcastle Crags since the days of our late President, Frank Murgatroyd. He wrote in his Flora of the Halifax Parish that "It is very rare and known only in the Hebden valley on a calcareous outcrop, where it has persisted for many years". However he was not able to find it for us on many visits since my time in the Society. Since we sadly lost him, several people have kept visiting the spot, but no sign of it was seen.
However, on Saturday 18th June, Annie Honjo found it! I persuaded Peachysteve and Philip Marshall to come and confirm it on Sunday, and they were satisfied it is Mountain Melick, Melica nutans. Charles Flynn also added his opinion that we had relocated it after seeing the photo.

So we are really pleased that it is still in existence there. The National Trust have kept the tree cover off the rocks for the sake of the special assemblage of plants that grows there.

Mountain Melick, Melica nutans

 Also on the Sunday I tried to lead the group to the other calcareous rock outcrop in the Colden Valley, but among the gloomy wet foliage (it had started to rain) I was unable to find the great boulder I had been to several times. Since then I've checked in Murgatroyd and he does list records for the Mountain Melick also being there on the Colden outcrop during the 19thC. 

Last week Philip found a grass with no previous records in Calderdale. Growing in a crack at the bottom of a wall at Mytholmroyd, he identified Water Bent from his seat on the bus! That shows a thorough knowledge of grasses, much greater than mine.

Tonight I visited the new bridge in the Copley Valley. I thought I had seen some Sand Martins among the Swifts over the Calder. There was a handful of them. On the ground I noticed a few fine rosettes of the stiff, bristly Fern Grass, or Hard Poa, Catapodium rigidum, which we had seen there before the development started. They are on the bare area on the left before the bridge going in the Sowerby Bridge direction.

Oak Biceps

Here is an Oak tree in the New Forest exhibiting its amazing strength.

The tonnage of wood on this horizontal branch is supported by the special cells which produce the interlocked grain at the junction with the main trunk. Also the branch will have tension wood growing above its centre to act like a bicep in an arm.

This junction is one of the strongest places on a tree and branches rarely fail at this point. The spiral grain on this particular branch also gives it greater bending strength.

Grass Flower

Who says grasses aren't colourful. This Meadow Foxtail is showing the lovely purple anthers and their attachment by a delicate filament, allowing them to vibrate in the wind and shed pollen.

Before this event the whole of the grass 'flower' envelope is tightly shut. At the base of this envelope of protective outer and inner scales are another 2 tiny scales (lodicules) which are attached to the ovary.

These Lodicules become turgid and expand, generating the considerable force needed to prise apart the outer scales, which allows the anthers and stigmas to emerge. Many grass species have their own time of day allotted for this to happen.

Anyone trying to 'name' the grasses will realise how different they look before the inflorescence is open.

The expanding of the individual florets is determined by the amount of light and when this is adequate the floret can open and exert anthers in just a few minutes. Mechanical disturbance can also initiate this and perhaps the grass is programmed to 'know' it might be windy enough to spread pollen.

Meadow Foxtail was probably the first forage species to be sown in Britain and prizes offered for quality as early as 1766.

      Illustration below is highly enlarged and a representation of one flower structure. Meadow Foxtail (above) has innumerable of these.

Incongruous Grafted Tree

This tree is a striking example of a Manna Ash--Fraxinus ornus, which has lovely creamy-white flowers in spring. It is grafted onto our more vigorous common ash, resulting in the strange mismatch at the graft union. Introduced to Britain in 1700.

The Manna ash is cultivated in Italy and Sicily for its gum, procured by making shallow cuts in the branches and allowing the yellow gum to harden in the air. It is then made into a syrup and used as a mild laxative.

Photos taken in Stanley Park, Preston.

June's Monthly Meeting and Presentation in a different venue (see poster)

--------------------------------------------------------------------------

We have had to book the Fire Station Community Room as our usual rooms with our library in the basement of Halifax Central Library are needed for secure storage of the Referendum postal votes.

Dr. Dave has given us some absolutely fascinating insights into his work in archaeology round the world and locally, and this one looks to be equally interesting.

It's a nice room, and we can have hot drinks/cakes. No need to bring anything. The HSS Council has got it organised.

Curious Elder bush

On the HSS walk to Sun Wood today, an Elder with linear cut leaves was noticed on the woodland edge .

It seems to be a combination of Sambucus nigra var. 'Laciniata' (Parsley -Leaved Elder) and 'Linearis'; not quite fitting the description of either. Laciniata has been known since the 16th century and does occur occasionally in the wild.

I suspect it is quite a rare tree, even in local gardens. Note the bifid and trifid, as well as entire linear leaves.

One or Three Sycamores?

How's this for a curious arrangement of Sycamore trunks at Downham? Presumably all from the same rootstock. Nothing like open-grown trees for character.

Don't look for Ancient trees in Ancient woodland---you won't find them there.

 

 

Beech Trees

In a field at Downham is this wonderful veteran Beech. It has fallen over many years ago and is now resting on its massive boughs on the ground. Never give up on a fallen tree if the roots are still in the ground. This lapsed pollard is growing and adapting itself to a retirement of leisure sprawled out in the sun.

Trees can often walk across the landscape in this fashion. The major threat being people who live in a different time-frame, think the tree is a gonner and reach for the saw!

Lime tree -- but not as we know it

In Clitheroe today I was intrigued to see a Lime tree that didn't look quite right. The flower bracts and the immature flower buds were obviously those of a Lime (Tilia) but the leaves looked odd.

On looking closer, I saw leaves which I had not seen before on this Genus. As you can see from the photos they are a puzzle. On looking in my tree book, the only one which seems to match up is Tilia miqueliana, named after Frederich Miquel (1811-1871) professor of botany in Utrecht.

One book says---"This species is unknown in the wild state and only occurs in Japan as a planted tree, most often seen in the courts of Buddhist temples, where it is regarded as sacred. It is reported to have been introduced from China (to Japan) about 1190AD but has not yet been found anywhere in that country. Its extreme variability points to a hybrid origin."

Introduced to the West between 1900 and 1904.

I've not seen one before. If anyone knows for certain whether my identification is correct, or whether I am barking up the wrong Lime tree, I would love to know.

Medlar/Midland Hawthorn

The natural hybrid between Medlar and Midland Hawthorn is now in full flower in Centre Vale Park Todmorden. It was previously 'lost' within Rhododendron which has since been cleared.

It has variable shaped leaves, some lobed some entire but the flowers are large and very attractive; not in clusters but single. Originally called Smiths Medlar when the hybrid was discovered in 1800 but now known as xCrataemespilus grandiflora.

Tod's flower has 3 styles, the same as Midland Hawthorn. I have never seen another of this hybrid. Edward Kemp planted some at Dobroyd Castle in 1869 under the name Crataegus grandiflora, which is considered to be the same hybrid under an earlier name. Kemp also did some landscaping at Centre Vale, so could it be one of his plantings?

Our Monthly Scientific Society Walk, May 2016.

 Emma Baker, our Geology Recorder, is leading a walk this Saturday, 28th May, 2016.                     The plan is to walk on the Todmorden Geology Trail.

 The meeting place is OL14 7JA (SD 918 247). At the crossroads of Sourhall Rd, Parking Lane, Flower Scar Road/Tower Causeway. There is some but limited parking.
Meeting at 10.30 am for 10.40 am.
Bring a picnic and a layer to sit on. Dogs are welcome if controlled as it is lambing and ground-nesting bird time. We will probably see and hear the haunting calls of curlews.
 Families welcome.

Any lifts needed from Halifax? I will leave town centre at 9.30am.

Coppiced Oak

This picture of a lapsed coppiced Oak was taken in Knotts Wood Todmorden. It is likely to be a very old tree looking at the size of the boulder shaped base. It needs more light to stimulate epicormic shoots from the base but unfortunately it is getting shaded out by other saplings.

Cult of the named tree

Not our area but still interesting for what it reveals about our blinkered sense of trees.

This is the New Forest and on the O/S map there is indicated the "Knightwood Oak", the biggest Oak in the New Forest at 25ft in girth and estimated at 600 years old. It has its own car park nearby and is specially ring fenced (a bit garden fence-ish) with historical notices. It is impressive and is obviously a lapsed pollard.

 

Knightwood Oak

 

 

Yet not 100 yards away there is this ancient centuries old tree, not named so not regarded, but just as interesting as the Knightwood Oak. It is hidden away and can only be sensed and not seen.
But if you look beyond the smokescreen of garden fences and nameboards, there are plenty of these other wonders in the woodland. This particular Oak was an open grown pollard in wood pasture until its space has been allowed to be invaded by young conifers.

Find the Ancient Oak

 

Here it is

 

Haloing round the Oak by removing conifer and Beech saplings will help it survive. Without any intervention its death will be premature. I always find it useful to look in the opposite direction to signboards and notices, where there is often far more interesting things to discover. Such as this Beech and Oak, again only yards away from Knightwood Oak but with no information board informing anyone what is going on. Yet the page from a 30 year old booklet describes it well.

 

Inosculation--a new word for me

Old booklet describes it.

 

It's an interesting world out there

Lousewort

Today I visited a meadow in the Holywell Green area,

it's a short grazed unimproved meadow with a great variety of species.

As I scanned around I totalled 26 points on the LWS Meadow Criteria List.

12 is considered good.

The highlights for me were Lousewort (Pedicularis sylvatica)

This is the third site I've been to in Calderdale with Lousewort.

 

Very clear in the short grass

 

Changing Forget-me-not (Myosotis discolor)

Now a common component of Wild Meadow Mixes

I rarely see it growing naturally but here it appeared en masse.

Bulbous Buttercup (Ranunculus bulbosus)

Our least common Buttercup which is usually scattered but here was abundant

Note the reflexed sepals below

There was also Heath Milkwort, Barren Strawberry, Bitter Vetch, Carnation Sedge and many more.

If you know of any hidden gems like this then please let me know.

White Holme and Turley Holes and Higher House Moor

On a walk along White Holme Drain, mainly looking for the beetle Carabus nitens (which at the second attempt this spring, I didn't see again), I did see several green tiger beetles and I'm fairly certain my first ever emperor moth.  It flew by at great speed as I walked along the track between Turvin Road and White Holme Res'.  I half - heartedly chased after it but it was soon lost over the moor.

Regards, Chris

This Month's Talk and walks - May 2016

AM poster

-----------------------------------

Weds 11th May. There is a Woodland Visit to survey for species with a view to creating a new Local Wildlife Site. The planned Grassland survey is cancelled, possibly to be  re-scheduled, as the meadow flowers are late.

This is to Parrock Wood, and Height Wood, west of  Hebden Bridge. Meet just off the A646 main road just after the Eastwood Sewage works on the bridge that  crosses the Rochdale Canal a few miles west of Hebden Bridge. Grid ref. SD968261. Park on the main road. 

Time 10.30 am for 10.40. Bring a packed lunch.

 Hugh Firman, Calderdale Conservation Officer, leading. Tel.07712867610

------------------------------

Saturday 14th May. The annual HSS ramble to Rishworth to see the very reliable Little Owl (sometimes the pair) and the Native Daffodils. Unfortunately the daffodils were in full flower a few weeks ago and are probably mostly over. This was due to a very mild early winter.

Many other interesting species to see and beautiful scenery.

Bring a packed lunch. We eat outside so a damp-proof sitting layer is useful.

 Meet at Mill Fold (Bowling Green) Car Park off the B6113 at Ripponden. 

10.30 for 10.40. Steve Blacksmith leading. Tel 07715005379

Tree Planting --- some reasons why

I have written this here rather than in "comments" to my other post on Tree Planting as things can get a bit lost in there.

I recognise there are many good new tree planting schemes done by organisations and individuals. But I think there is a need for debate and reflection, which is what I present below.

There is a scheme called "Keeping Rivers Cool"

http://www.woodlandtrust.org.uk/mediafile/100814410/pg-wt-060216-keeping-rivers-cool.pdf?cb=a8aa1f98391e4baa94a9fd973345c879 

which is designed to protect certain rivers from the effects of climate change, particularly the salmon and brown trout. The River Ribble is one of these, including all its headwaters and streams, which is why the little Wycoller Beck has been blizzard planted as in my previous photo.

Also this EA link is very good:-

http://www.asfb.org.uk/wp-content/uploads/2012/09/Keeping-Rivers-Cool_Guidance-Manual_v1.-23.08.12.pdf

If you read the above pamphlet by the Woodland Trust it does explain how this should be carried out. There is really good advice about leaving glades, self-seeding via fencing-off, avoiding flower rich habitats etc.

It also contains the recommended planting distances of 2 to 3 metre spacing. This is for quick canopy closure to gain 'control' (i.e. vegetation suppression) quickly. This spacing seems to be a general recommendation for most tree planting schemes. I don't know where this originated, unless it is a throwback to commercial FC conifer plantations but it seems very wasteful in terms of resources and labour.

And there lies the problem. This 'control' of vegetation on many sites is so complete it goes extinct, particularly when the planting body has no rights over the land and what the private owner may do (or not) after a few years. The planting scheme might have pleasant visions for the future but the actual landowner have none.

It may be better to recognise this probability and space the trees out in the first place.

Oak saplings don't need weed control, they will grow strongly through grass. The acorn is designed to do this for when Jays plant them outside existing woods, or in very open woodland glades.

Oak is a pioneer species, more so than Birch which prefers bare ground or is an opportunist in existing woodland. Paradoxically you won't get Oak saplings in an Oak wood. Just as you don't get Ancient Trees in Ancient Woodland.

What seems to happen on the ground, however much prior ecological surveying is done, is the usual uninspired close planting. The numbers of saplings are ruled by the Grant system.

There must be a way of designing (and paying) for new woodlands that will last for the future and actually work for people and wildlife--or what is the point in them?

Having said all this---- the most important thing for any woodland, new or old, to exist long term is to keep the sheep out.

Walshaw Moor Burning Off 10 15 to 03 16

Heres just a sample of the New Intensity of Burning Off on the Walshaw Moor Estate from Oct 15 to March 16,all for the sake of artifically boosting the numbers of Red Gouse which then can be Blasted Out of the Sky, for  so called Sport !!How this benefits Our Climate,and environment is totally beyond words.This victorian Practice needs consigning to the History Books Now,before there is nothing left !!  

Ramble this Saturday

There will be a walk this Saturday 30th April 2016 in the Tenterfield and Friendly area of Sowerby Bridge.

It is Peachysteve's "Friendly" flower identification ramble. Meet outside Sowerby Bridge Cricket Club at 10.30 for 10.40. HX6 1AN

Easy walk; families welcome; no picnic needed and no charge. Dogs will be attending so others welcome.

 Butterbur at Cromwell Bottom Nature                                                                                                              Reserve this week.

TREE PLANTING---IS IT TIME FOR A RE-THINK?

These newly planted trees are by the river in the Forest of Bowland. Not sure what to make of it really but it is very similar to many such tree planting schemes taking place everywhere. The other photo is of a similar blizzard of trees by the beck near Wycoller, planted amongst lovely wild flower riparian habitat.

 

One needs to ask what is the point of all these cheek by jowl trees; is there a management plan or a purpose in mind. As far as this scheme by the Hodder, I would guess there are upwards of 500 saplings planted in a small area that would support perhaps 30 mature trees to leave the necessary space for flora and understory.

It may be that 470 of these saplings will be coppiced as time goes on. But even that would be an excessive amount of coppice for a small area and the multi-stemmed stools would impinge on each other with no room for anyone to stand up, never mind wield a billhook. It will be interesting to see how it develops. Look at the attractive mature tree in the background; will any of these saplings ever provide a future replacement?

I have come across many such plantations before and it is never a pleasant experience. Umpteen years on the forgotten saplings have grown like tall matchsticks; the previous ground flora extinct because of the deep shade.

But worse than all that is the waste of time, because if the matchsticks are belatedly thinned out, the remainder bow to the ground in shame. All that can then be done is cut the lot down, throw all the supposedly bio-degradeable plastic tubes in the waste skip and start again.

Blizzards of trees don't make a woodland; space them out and you can have characterful trees with branches, as well as a ground flora. Also don't forget to create new pollards--these are the trees that have the potential to remain for centuries--long after the others have gone out of memory.

 

The old motto is wrong; it should read "You can't see the trees for the wood".

Request for the toad records and a joyful re-find!

I got just four toads last night at Boulderclough site. It seems to be coming to an end, but don't take my word for it - check the thermometer and your stretches of road. I'll be going out later tonight.

When you are convinced the migration is over the Hx. Sci Soc would greatly value your counts, including dead amphibians. Just basic numbers and species is OK, dates being very important.

I am named organiser only for Bolderclough Dam with Froglife; you can register with them and send in your own records, or I can send them to Froglife with my Bouderclough counts.
If you look on their website you will see they collect slightly more detailed records if you use their form. I only send fairly basic records as I don't have time to do everything they ask; I am recorder of birds with HSS as well !

I was unable to find a volunteer for the Thornhills Beck Lane site after Margaret had to go on holiday. But thanks for saving those you did, Margaret.

I offered to show people toadspawn who weren't lucky enough to spot any, and have some in a bucket here. Sunday 24th April late afternoon/ evening is a good time for me. I can bring it to Boulderclough, then to Woodhouse Rd. Todmorden, as a suggestion of possible arrangements. Or in Halifax if you're passing. Leave your comments below if anyone is interested.

________________________________________________________________________________

Daffodils, native and unplanted ones, were recorded at Hippins Clough, near Blackshaw Head.  This is in the Halifax Naturalist, which only ran until 1908, so the record is at least that old.

I've looked without success for several springs, and we found them on Sunday 17th April!  I spotted a clump of five, and Annie Honjo added another seven scattered about.

They are in the upper part of Jumble Hole Clough ( it becomes Hippins Clough at some point ) about 150 metres below the ruined Staups Mill.

They are half way up the steep slope on the side opposite the footpath. There are dandelions, Lesser Celandines and other woodland flowers around there. You need binoculars to be sure of the ID.

Perhaps they only escaped the collectors by the steep and wet situation they grow in.

There are about another half dozen sites, mostly around Halifax, in the old records.

Spring update

A brief update on a wood in Todmorden.

Couple of weeks ago 6 small tortoiseshell and 1 Comma, also Chiff-Chaff. Today a speckled Wood, male Blackcap, Nuthatch and Long Tailed tits and a few Swallows overhead and a Buzzard.

Only the odd few Meadow Foxtail in flower--very late for this grass and is beaten this year by Sweet Vernal, which rarely happens.

Mountain Melic in flower today, as are Kingcups. Lots of Tortrix moths flying about, which suggests the Oak buds are swelling.

Whiteholme and Turley Holes and Higher House Moor

With the sun out I thought I might try the moor in the slim chance of an early emperor moth and/or  the beetle Carabus nitens.  It was still rather chilly and damp up here and I didn't see either.  There weren't many birds about either, apart from red grouse, curlews, meadow pipits, a lone swallow heading west and a redshank was heard.  I did however find four species of sphagnum moss, including S. fallax, S. denticulatum, S. capillifolium and possible S. palustre.  There were also some (recent) significant carvings on Closet Stone (or thereabouts).

 S. denticulatum

 S. capillifolium

 S. palustre?
