Adult Caddisflies

Yesterday (23 Aug 2018)  Craven Conservation Group had "An insect day at Broadrake Farm. We looked at "Bycatch" in the moth trap.

I took some Caddis-flies round for Sharon Flint to identify.
Potamophylax cingulatus 

Here is a Potamophylax tying to escape, crawling onto Sharon's book.

Potamo (Greek) = river
phylax (Greek) = guardian, sentinal
cingula (Latin) = girdle. belt




Limnephilus sparsus  
Limnephilus sparsus  
Limne (Greek) = lake or pond
philus = loving
sparsus = scattered


This now increases my life list of adult caddis flies from one to three.
The first one I have remember seeing is

Limnephilus lunatus

Limnephilus lunatus



Limnephilus lunatus has a half moon shaped transparent area at the end of the wing.

The Permian Bockram Breccia - rocks newer than Carboniferous near Westhouse

Wheyyy - not just pretty flowers and sedges and lichens in this blog.  

Today it's geology..

I am going to write up how I learned that there are rocks newer than Carboniferous around here..

Roger and Liz Neale led an excellent day for Craven Conservation Group on the special rock formation which shows up in the stream bed near their house.

The Permian Brockram breccia





Here is what I wrote for a press release:

Craven Conservation Group were led on an exciting trip to see the “Permian Brockam Breccia” exposure at the gill below Fellbeck Farm near Westhouse on Sunday 12th August. 

The fact that the stream was (almost) dry meant the group could explore the sunken stream bed. 

Twelve members and friends attended the day led by Roger and Liz Neale of Bank House, Westhouse. 

Roger gave an introduction to Local geology in the morning and the group helped him sort specimens and look at how different types of local rock were used in different parts of the building.

Oyster Mushrooms, Horsehair Fungi and Field Mushrooms were spotted on the walk.



Roger had run the event the previous day for Cumbria Wildlife Trust- Kirkby Lonsdale Group

Roger explained how

Breccia is rock that is made out of angular pieces of rock that have been cemented together with sand.  At the base of the hills at this end of Craven - e.g. Ingleborough - are ancient sandstones/slates. On top of these are rocks formed in the Carboniferous period:  limestone, then the Yoredale Series (sandstone, shale and limestone layers) and then millstone grit at the top.  In the next geological period, the Permian, (which began 289.9 million years ago) desert conditions prevailed. There was a huge fault (cliff) maybe 6000ft high. In the desert occasional flash floods brought a jumble of sand and rocks over the limestone cliff. Some of the cracked rocks got cemented together to from the breccia, now called the Permian Brockram.




 oooooooooooooooooooooooooooooooooooooo

The next meeting of Craven Conservation Group is An Insect Day at Broadrake Farm (Near Ribblehead  SD 740792) on  Thursday 23 August, 2018.   10am - 4pm. We plan to open the moth trap at 10am.

30 Days Wild - Day 16 - St Robert of Knaresborough's Cave and the delights of the Nidd Gorge

Knaresborough lies on the River Nidd.


The Anglican Centre in Rome  has a library, organises courses and hosts meetings when important Anglicans go to Rome for Catholic events. They have support groups in the UK . The Ripon Support Group decided to have a special meeting this year at the Parish Church of St John the Baptist in Knaresborough to celebrate   800 years after his death, the life of Knaresborough's own saint, Saint Robert.



The day event on 16 June comprised:


  •  A talk about the Anglican Centre in Rome
  • A talk by Peter Lacey on the life of St Robert (.. or more precisely the life and conditions of the people living around Knaresborough at that time)
  • A talk by Ruth Beckett on “A Great Cloud of Witnesses: Theologies of Sanctity; Theologies of Healing”
  • A walk to  visit Robert's Cave


Click here for  background material on St Robert and Knaresborough 
and more here


We met at the Parish Centre just beyond St John's Church



Peter Lacey is preparing to give his talk



Peter has written a novel, or rather a set of short stories about people who knew Robert, called "Tales of the Celebrity  Hermit". Robert stayed within the north of England
From the forward of this book:-

Robert Flower (c1160 -1218). or St Robert of Knaresborough as we have come to know him lived 800 years ago. He was brought up in a well to do family in a prosperous and growing region of Europe that was still taking shape after the Norman Conquest of the British Isles. Robert's home town of York and his adopted town of Knaresborough provide the immediate setting for our stories, but the influences and reflections from a larger canvass are never far away... when established in St Robert's Cave, sometime in the 1190s he was becoming something of a celebrity. He was visited and spoken about across Europe...


The river Nidd marked the line between the town of Knaresborough to the north and the Royal Hunting Forest -Knaresborough Forest to the south. This was not necessarily forest - It was land where the King had rights to hunt, and where there were draconian laws against people who broke the rules.


Peter presented a comprehensive picture of the environment and life in those times. Climate graphs to show what the climate was like in those days; He talked about economics - and how the people and economy were suffering as King John had had to borrow money for the wars he had been fighting (and mostly losing) and now had to pay it back (using taxes etc, so that a lot of the silver coins which were being used in the currency were then removed)

He painted a picture of some of the economic and social problems of the time - which have parallels today.


At lunch time I left the lecture room/parish room and went onto the patio outside - and was amazed by the view





The speakers and organisers sit on the patio
The castle beyond
The castle was first built by a Norman baron in c. 1100 on a cliff above the River Nidd. In the 1170s Hugh de Moreville and his followers took refuge there after assassinating Thomas Becket. In 1205 King John took control of the Castle. It was here in 1210 that the Maundy Money was instituted.


Lunch





Gives her talk



We set off on the 1 1/2 mile walk to the cave. (Most people drive). We descend lots of steps then walk on the road by the river. Looking back, The Parish Centre is under the left arch. 


I have now just set off on the mile and a half walk to Robert's Cave. I had not realised the gorge was so impressive. The original route of the Nidd is through the gravel beds of what is now Staveley Nature reserve two miles to the north (where I am due to give a grasses workshop next month), but during the last Ice Age, the Ice sheet flowing down the Vale of York blocked up the river, it was diverted, and with all the extra melting water formed this gorge through the magnesian limestone.




There are big trees in the gorge - Sycamore, Ash, Oak and others.


Some trunks have been carved


Kingfisher



Eventually the land flattens out. Robert was given some of this land to farm with his small community. 

A while after his death a Priory was set up. Trinitarian Priory of the Holy Trinity and St Robert, founded pre-1252. It was destroyd by the Scots in 1318, and suffered at the Black Death. It was dissolved in 1538. It was destryed at the dissolution of the monasteries, but there are bits of masonary used in buildings along the route, and vuildings named after it.





Still walking along the road



Leave the road and descend the river bank to the cave

 On the way back I look at the chapel carved into the cliff. The tiny medieval Chapel of Our Lady of the Crag lies a stone's throw from the Nidd, in Abbey Road about half a mile from the centre of Knaresborough. It was carved from the cliff face by John the Mason in 1408, permission being granted by King Henry IV.






A lot of work is being carried out on the steep garden below - a section on medicinal plants, a section on plants with a story or religious title, a a section to remember people.

I wonder how many plants will continue to grow with the dense shade of the trees above... But do go and see them now whilst they are fresh and flowering


Another splendid view as I return


30 Days Wild - Day 15 - Part-1 What do Nidderdale AONB Botany Volunteers discover today?

On 15th June we set off for Bank Cabin Wood, via the road to Harewell Hall.
Passing a wall with Klebsormidium crenulatum on the way 
 Bank Cabin Wood is a "SINC" site (Site of Imporance for Nature Conservation). We had lunch on the path through the bracken  (that had recently had some saplings planted in it), identifying grasses that grow on acid soil (and attempting to identify a willow-herb). there  were a few plants of Climbing Corydalis in the bracken.

Then we progressed down through the bracken to the stream. Here was woodland on wet acid soil - Alder and possibly Grey Willow.

Then we found a BIG sedge.
This is one of the participants scratching her head. I two was scratching mine.

It was big. Not big enough for  Carex pendula.
Not red enough at the leaf tips and based for Carex binervis, but awfully like it. Anyway Carex binervis grows on Heather moorland, and this place was rather too shady and damp for heather
Not shining yellow green enough for Carex vesicaria
Add caption







It is a tall tuft, growing amongst the Luzula sylvatica. The male and female heads show up against the black trousers. 

It turned out to be Carex laevigata - growing in exactly the habitat it should - damp woodland.



Carex laevigata


The sheaths and stems are much more sharply triangular than Carex binervis. Carex binervis does have a flat /tongue shaped tip of the inner-face of the sheath so is a bit similar this way.


Carex laevigata has a long acute ligule, whereas C binervis has a short one.




The dead leaves and scales at the base of the shoots are brown, not reddish orange as in C binervis
Here is a view I took the following day. We were in the valley below the mast
We also found some Carex pallescens - Pale sedge


Mentha verticillata - Whorled Mint (A cross between Mentha aquatica and Mentha arvensis)





Scutellaria galericulata -
Common skullcap - this has blue flowers

  




Finally an invertebrate -

Eriophyes laevis a gall on alder leaves caused by a mite

    
We had only tackled a tiny part of the site but had had a good day.

--I may write about the invasive plant Cotula alpina that I checked up on, "on the way home" later that day

The next day I would be going to Knaresborough to see the cave of St Robert....

30 Days Wild - Day 14 - Waves - and Mr Fox


. Strong winds this morning
Waves travel down the cross section of grass revealed by the grass cutter
By evening the weather settles down and I walk by the Ribble. 
There is a light breeze.
Why are there ripples on this side of the river but not the other?
Is it to do with depth of water?

I must read more of the excellent book "How to read water" by Tristan Gooley


I watch the family of ducks.. Mrs Duck is quacking, and her "teenage" children stay with her. Are they are they staying in the deeper water?  I realise I am not the only one watching them. On the far side, Mr Fox comes down to the waters edge.. 
Sadly my Olympus Tough camera that does such brilliant close-ups for some reason won't focus when the camera is set to telephoto so my video comes out blurred.. this is the best shot I can manage

The arrow marks the fox

 If the river gets much shallower, Mrs Duck won't be able to avoid Mr Fox..  but then maybe in a few more weeks her ducklings will be able to fly.
These are not waves, rather potholes worn in the limestone bed of the river
 - they are normally covered by water.


Coming shortly:- Tales of the Nidd ..
