Hay Meadow Walk : Saturday 21st July

Visit the lovely National Trust hay meadows and find out just what is growing in them with the help of Ranger Natalie Pownall. The current glorious weather may have had an adverse effect on the species growing in the meadows, but let's see what we can find!

Meet at 10.30am Clough Hole Car Park, Widdop Road, Hebden Bridge HX7 7AZ, then a half mile walk along the road to the hay meadows.  Car park charge of £5 for non-members of the National Trust, but new members signed up on the day will have the charge reimbursed.  Very sorry, but no dogs please.  Nearest loo is at Gibson Mill.  Stay for as long as you like up to 3pm.  Bring a picnic.

PS.  And yes, you're quite right, the picture ISN'T of Hardcastle Crags, but was taken a few weeks ago when the meadows were looking good at Mytholmroyd!

Lime Trees

Here is an extract from an information board at Silverdale. I find it astonishing that Small Leaved Lime can be thousands of years old. At one time is was the dominant tree of the wildwood in many parts of England and not the Oak.

I have planted a few Small Leaved Lime (Tilia cordata) and they are fast growing on suitable sites. They are insect pollinated and bees love the summer blossom. Stand under a Lime tree and listen to the hum of the bees.

I wish it were included in tree planting schemes but it seems a forgotten tree. It coppices and pollards reliably. It grows the tallest of any native tree and tolerates shade nearly as much as Beech. Maybe the Common Lime used in many roadside plantings have given it a bad reputation, particularly with car owners.

Let's speak up for T. cordata and include it in the new plantations.

Our next indoor meeting, a talk by David Glover, open to the public

Local nature stories

                                           Which came first, the stone shed or the conifer?

                                                  Nature will always take over the show. This is the notice board for the Southern Marsh Orchid site in Todmorden, where there are now fantastic numbers. I met with IET and Calderdale's Property Manager nine years ago to ask them to avoid planting where the orchids were.  Rather a shame the notice doesn't highlight the nature value of the site, although the moss value of the board is interesting.

Southern Marsh Orchids in Todmorden

Saturday's Walk 30th June

Gorpley Clough and Reservoir. Set in the bare wild hills west of Todmorden, this is a beautiful area but is threatened by industrial-scale forestry.

Come and see it before it is scarred forever by the hand of man.

Not that the walk leader is against all trees, but NATURAL NATIVE trees, growing along the water-courses would be aesthetically and ecologically more desirable.

I expect the stumps of  a grove of trees will be visible which grew before the peat formed. The peat shrinks down in very dry years. These trees are recorded also in the name of some nearby rocks, "Shaw Stones", where prehistoric people made cup-marks which can be still seen.

The area is rich in visible archaeological evidence, and is also geologically interesting. One tufa spring is easily seen, and I have found another higher up above the reservoir.

The entrances of old coal mines are now grid-covered to stop children playing in there, where they were once forced to work.

The walk is about 4.5 miles, but with some steep paths and one long flight of steps. We will not be going fast! Picnics will be eaten at the reservoir. Bring insect repellent for inside the woodland! Shorts are not recommended due to ticks.

Meet at 10.30 at the car-park on the left in Bacup Rd. at the bottom of Gorpley Clough OL14 7HL Come along and share your opinions if different from mine. We can have a civilised debate. Everyone has a voice at Halifax Scientific Society events.

Large Skipper

Photo at Ringby Lane, Ploughcroft, Halifax, today.

Foodplant for the larva is usually Cocksfoot grass. A common and easily-identified grass once you get your eye in for it. Apart from good for butterflies, summer is the best time to learn and appreciate the many kinds of grasses that flower in Calderdale. 

I should point out that despite being the "Large" Skipper it is only 12 -18 mm long on it's fore-wing. (M.Chinery)

The other two Skippers we get in Calderdale  - Small Skipper and Dingy Skipper (infequent) are very slightly smaller. The Large and the Small are quite common where sun-drenched long grass is allowed to exist.

Beech Leaf Miner

I am noticing many Beech trees that look to have brown leaves from a distance. On closer inspection parts of the leaves look to have been eaten out by a leaf miner and the remaining healthy tissue has many holes.

It isn't just confined to young saplings but old Beech are badly affected as well. It could be the result of the Beech Leaf Miner--Orchestes fagi. I can't say I have noticed this much damage to the leaves in previous years.

Less Chlorophyll will mean less photosynthesis and progressively weaken the tree. In combination with this lengthy dry spell and Beech having a shallow root system, it is not looking good.

Is this type of leaf damage noticeable throughout the valley or is it just Todmorden? Can anyone confirm this weevil is the culprit?

Balsam Bashing at Hardcastle Crags

Natalie Pownall, Academy Ranger at the National Trust, has asked us to advertise the forthcoming balsam bashing days which start on Monday 18th June.  Many HSS members volunteered last year to do this.  You can stay for as long or as short a time as you wish. 

This is what she says:

'We want as many people bashing at the Crags as possible to increase biodiversity and reduce flood risk. The aim is 1000 people!

The sessions are in the day this year instead of the midgey evenings!

Here’s the link to our balsam bashing drop in sessions which gives full details of timings, dates etc.

https://www.nationaltrust.org.uk/events/db73a812-a05f-4207-997e-11bcb9729860/pages/details

There are 6 sessions in the next two weeks 

Hope you can help us spread the word – share with your friends!'

Tree planting--what's the plan

Shedden Clough near Hurstwood has had a lot of tree planting that also includes the open moorlands. Most of this was done as part of the now defunct "Forest of Burnley" scheme.  Some trees lower down the valley sides may create a good effect but I do wonder what they are trying to achieve when saplings are planted on the moorland, especially as there are many Small Heath butterfly and quite a few Skylarks. Many of these saplings  are looking distinctly unhappy and will not survive. I am sure that wasn't the intention although it could be seen as a good outcome.

Within Shedden Clough there is a lot of Rhododendron that is spreading quickly. Some of this Rhodo was cleared about 10 years ago. As the photo shows, the resultant bare soil has created a great opportunity for a forest of self-seeded Birch. Note how this Birch has established without the assistance of tree tubes and stakes; perhaps it prefers to do what it knows best, which is grow.

Of the planted saplings, Hawthorn and Willow seem to be doing well. If these were planted as a kind of first wash on the landscape canvas, niches would be created for trees to arrive naturally and create a more structured woodland over time.

Instant woodland is fostered by the grant schemes and impatience but the question has to be asked---what will be the result?

The prospect of the "Great Northern Forest" sounds appealing but if it is like many other planted schemes that are done and then forgotten, the results may be the opposite of what is wished for. 

Anyone who is interested in how successful landscapes can be created, that work for all species, should 'Google' Knepp Wildland and watch the 15 min video. It is a revelation how such a landscape can evolve from a previous intensively farmed one.

House Martin Nests 2nd June

A whole terraced street full of House Martin nests at Portsmouth, nr. Todmorden. Lennox Rd. near the level crossing and the former Roebuck Inn. About ten nests and about 30 birds flying around, many building, others clinging onto the walls under the eaves, chattering.

Withens Clough and Cragg Vale

I went to check to see if there were any surviving butterwort after the wall collapse and subsequent repairs.  Sadly I couldn't find a single star of leaves and it looks like it is lost.  Having known it at this site since a lad in the 1980s, I don't mind admitting I feel gutted about it.  Some consolation was the Jacob's Ladder nearby, which I first saw at this location in the 1980s too (the bumblebee is Bombus pascuorum).
Below Little Manshead Hill, the hay-meadows looked stunning with their displays of meadow buttercup.
