Frogs and trees cross roads

The severe storms of mid February wrought havoc and mayhem in North Wales.Thousands of trees were blown down blocking railway lines,roads and severing  electricity power lines. Dol y moch was without power for almost two day resulting in Frederick Bird and Spongate Primary school groups having to return to Coventry. However the good news is that both schools have had their courses re-scheduled for the summer.
At one stage road access to Dol y Moch was completely blocked by several fallen trees. (See below)

This is where the coach stops when dropping off or picking up school groups

Sadly the lovely old cherry tree that once stood in front of the house and which produced spectacular displays of pink blossom each spring, is now no more, along with many oak trees in the Dol y Moch woodland.

The end of the Cherry Tree

But even in stormy February a few spring flowers were braving the weather, Lesser Celandine making an appearance on the 16th and Daffodils on the 20th.

In March the Jet Stream slipped northwards heralding a change to calmer conditions and a feeling that spring had finally arrived.(Well almost)

Wood Anemones in bloom were spotted on the 20th March, a single white Bluebell on the 30th, and on the 2nd April,  Bluebells proper were beginning to flower.

A surge of unseasonal warm, dusty air coming up from Africa and the Mediterranean took my shade thermometer to just under 22 C on the 30th March; However, I understand that officially,  Porthmadog was the warmest spot in Britain with 21C recorded!

Heavy rain on the evening of 31st coupled with the warm air brought masses of migrating frogs out onto the steamy roads......quite a wildlife spectacle but hellishly difficult for driving.That night I drove from Caernarfon to Porthmadog and had to dodge hundreds of frogs wandering across the road; fortunately their light coloured skin under their chins stood out in the car headlights so I was able to miss them by driving slowly and safely. However, noting the speed of other cars that evening it would appear that their drivers were either unaware of the frogs or unconcerned.............in both cases that was a pity.

Our migrant bird species began arriving on the 20th March but more about that in my next blog very soon.

Bluebells and Global Warming

This morning there were whining sounds of chainsaws from across the Glaslyn floodplain, the woodmen dealing with the trees that have succumbed to yet more gales.Ironically as I listened to the chainsaws I too was cutting and chopping wood from trees blown down in the storms of 2012!
The west coast of Wales has certainly taken a battering of late.Two days ago (1st Feb ) a Force 9 gale lashed the local coastline but today the wind had dropped to Force 5-6 . With the sun giving a rare appearance, I decided to venture down to the little  seaside town of Criccieth to see how it had fared.
As expected the tide was very high, and huge waves were thumping against the seawall and esplanade,but no obvious damage was visible.However the cliffs on the west side of Criccieth had suffered severe erosion with large sections having collapsed into the sea.
Further along the coast where the land is lower the sea had surged  over the top of the beach, scouring the land and dumping masses of sand, pebbles and sea borne plastic rubbish over a wide area.Most of the damage that I saw was actually caused by the severe storm on Boxing Day.
Although the weather so far this winter has been exceptionally wet and stormy, it has been mild and that has encouraged the spring flowers to start growing earlier. Our Snowdrops have been in flower since Jan 8th and the Daffodils are now 20 cm high.Bluebells have also made an appearance,their bright green shoots pushing up to 5 cm above ground as shown in the photo I took today (4th Feb )

There are also two other spring flowers in this photo; on the left with feathery leaves is Pignut and on the right,the heart shaped leaves of Lesser Celandine.
So the spring flowers are on the way but the Frog spawn is already here.............see below.

This small healthy clump I spotted today but I guess that it has been there for a couple of days..............so deposited probably at the beginning of Feb. Last year I noticed spawn in the same pond on 6th Feb.
It's lovely to hear the birds singing once again especially the Mistle Thrush calling from the tree tops.I even saw a pair of Robins mating which is very early indeed.There are plenty of ducks down on the marshes including Teal,Wigeon and Shovelers. Flocks of Canada Geese,Whooper and Mute Swans are busy grazing the farm fields.
On the 30th Jan I heard a Vixen barking at dusk from the woodland
near my house;checking my notebook I heard a vixen on the 20th January last year from exactly the same place.
If you are a regular follower of the Season Watch blog you will be aware that I record the occurrence of seasonal life cycle events of particular animals and plants  as mentioned above.
Recording events like these and  their relationship to seasonal climate and habitat influences is called Phenology and has proved useful in the study of Climate Change and Global Warming.
Using records compiled over many years has enabled scientists to monitor trends in animal and plant life cycles that can indicate  changes in global temperatures.For example,the early growth of spring plants and arrival of migrating birds species indicate that Spring is beginning earlier as winters become milder.




  

Seals, Snakes and Long-shore Drift

Back in November the children from Stoke Heath Primary school spotted this young Common Seal in the Dwyryd estuary near Borth y Gest. It would have been born during the summer, probably further along the coast of the Llyn Peninsula. Single pups are born on tidal rocks or sand banks and are able to swim and dive from birth.The other species of seal seen around our coast is the Grey Seal.The Common Seal can be distinguished from the Grey Seal by its smaller size and short muzzle with a concave profile between forehead and nose. Also the closely set nostrils form a V as clearly shown in the photo. Another unusual encounter occurred higher up the estuary when a canoeing group from Ernesford Grange school came across a huge wooden sphere, almost a metre in diameter, partially submerged in the river channel. Unbeknown to the students they had discovered a work of art on a journey through the landscape! The journey began in the 1970s when a local sculptor, David Nash, carved the giant ball from a huge fallen oak in woodland near Dol y Moch. When completed, the ball was rolled into the nearest stream with the idea of following its progress and interaction with the environment over time. I well remember watching its eventful journey down the stream over the years as I often visited that tributary  stream with groups of students studying freshwater biology. People from all over the world would come to photograph the ball on it's journey as David Nash is a world renowned artist. Eventually the ball was washed into the River Dwyryd to begin its journey to the sea and beyond. Over the intervening years there have been many sightings as the ball was moved by the ebb and flood of the tide, but it  would also disappear for years on end. So, by finding it, I think that the students from Ernesford Grange have made a significant contribution to the history of the Giant Ball! 

Tremadog Bay from Criccieth with the Rhinog mountains in the background.  November 2013

When the wind is light and from the east  Tremadog Bay looks like this..........a mill pond. On Christmas Eve the scene was very different. Gale force south westerly winds heaped the sea into large  destructive grey waves that battered the coastline. It is at these times that whole beaches can be swept away together with the sea walls they protect. A beach is a very important front-line sea defense structure. Criccieth beach, shown in the foreground, has a series of groynes ( wooden barriers) that prevent the beach from being swept away. Waves crashing onto a beach  pick up the sand and pebbles, moving them sideways along the shore line.This process is called Longshore Drift. Longshore drift on Criccieth beach (foreground), and Harlech beach (background) moves beach material from right to left, both converging on Blackrock Sands (far left in the photo).
The groynes on Criccieth beach trap the eroding sand and pebbles and so maintain the beach. The beach in turn  protects the Sea Wall, Guest houses and Hotels behind it. Next time you spot a groyne at the seaside, check the beach level on both sides: the highest side is the side collecting most transported material and therefore faces the direction of Long-shore Drift.

Moving inland now to my compost heap! I recently had a pleasant surprise when I discovered the remains of a snake skin (shown below) on the end of a bramble shoot that I  pulled out of the heap. Snakes periodically moult their skin which can be used to identify the species to which it belonged.

The three native snakes in Britain are the; Grass Snake, Adder or Viper and the Smooth Snake. The latter species is very rare and confined to southern England. Therefore, the skin must have come from either a Grass Snake or Adder. Checking the shape of the preanal belly scale indicated that it came from an Adder, a very beautiful creature.

REMEMBER!
A bite from an Adder(Viper) is rarely fatal.
Keep calm.
Get help.
Avoid vigorous activity and never  cut or suck a snake bite.

In general as high summer merges into autumn the air temperature trends downward while rainfall and windy conditions increase.  The predominant wind direction was south of west bringing warm, moist air from the Atlantic.However these data show that September was a quieter month weather wise.

Smells and Spores

During the first week of November Snowdon received it's first significant snowfall but since then it has been washed away by lashings of rain. Down at Dol y moch we experienced our first frost of the season when the temperature edged below zero to minus 0.2 C on the 9th of November.I live a few miles west of Dol y moch towards the sea and here the temperature only got down to plus 3 C thanks to the warming effects of the 'Gulf Stream'.Without the frosts the trees are still hanging on to their leaves.....the birches and Larch trees have turned a warm yellow and look striking against the dun hues of oaks.You might remember that I mentioned in my last blog the scents and smells of autumn.Since then I have taken the opportunity when out in the countryside to try and recognize  individual scents and smells.For example,this morning I went for a bike ride to Aberglaslyn; my route took me across boggy flood plains, passed farms, through oak woodland dripping with dew, beneath tall beech trees standing in carpets of fallen leaves and finally into the gorge of the Afon (River) Glaslyn with its clear, cold  water cascading over  moss covered rocks.They all seemed to emanate their own distinct smell......it was fascinating.Next time you go for a walk, why not educate your nose!
Still on the topic of smell,over the last few weeks Ivy has been in flower producing a very distinctive musty ( not unpleasant ) scent.

Mushrooms and toadstools (fungi) are of course one of the star attractions of autumn and the damp, relatively warm weather has promoted the development of their above-ground spore producing structures (fruiting bodies).

Sulphur Tufts, Hypholoma fasciculare

There is a fantastic range of shapes, colours, textures and smells. Some fungi are edible but some are deadly poisonous. The Sulphur Tufts shown above are not edible and can be mistaken for the Honey Fungus, Armillaria mellea a deadly parasite of trees.Both species look very similar and both grow around the base of trees.
One way to tell the difference is to check the colour of their spores by making a spore print like the one shown below.

To do this ,carefully remove the cap from the stalk of the mushroom and place it gills downwards on a piece of white paper  and leave for a day.The spores will be released from the gills and deposited on the paper making a beautiful pattern identical to the gills.In this case the spore print colour is purple/brown which indicates that the mushroom is the Sulphur Tuft.In contrast,the Honey Fungus produces a  pale cream spore print.

Down on the Glaslyn marshes I saw Greylag Geese, Goosanders, Little Grebe, Redshank, Heron, Wigeon and Turnstone. Lower down, at Borth y Gest, the children from All Saints and Earlsdon Primary Schools spotted a pair of Cattle Egret.
And finally there are still a few butterflies about like the Red Admiral in the picture below that was feeding on fermenting fallen apples in my garden between the 10th and12th of November.

Mists and Mellow Fruitfulness

I really look forward to the colours and smells of autumn and to those quiet days when the early morning mist hangs above the River Glaslyn.

The Afon Glaslyn looking north towards Moel Hebog 

The mists had lifted when I took this photo but just out of view and to the right,Snowdon was still wearing it's cap of cloud.

On the left bank of the river, I could see patches of Michaelmas Daises  mauve against the seasonal browns and ochre.

The flowers of Red Campion still linger along the roadsides at least until the first heavy frost. Red Admiral,Tortoiseshell and Comma butterflies are still on the wing and feeding on Sedum spectabile in my garden.

I mentioned in my last blog that 2013 has proved to be a 'Mast' year where bumper crops of fruit and nuts have been produced. Millions of acorns have been raining down from the oak trees bouncing off car windscreens and making walking and riding a bike a bit tricky as they act rather like marbles......and have you ever tried walking on marbles! At least there is plenty of food for the squirrels, mice, pigeons, jays, pigs and deer to name a few. Acorns do however contain toxins which can kill cattle if too many are eaten.

The species of oak tree that grow in Dol-y-Moch woodland, and in north and west Britain, is the Sessile Oak,(Quercus petraea).In Warwickshire and lowland Britain the dominant species is the English Oak (Quercus robur).How do you tell the difference?

Look at the photo above of Sessile Oak acorns and note that they are attached directly to the twig. Acorns of the English Oak have a little stalk 4-6 cm long.Go and check out the oaks in the Memorial Park!

Earlier this year while biking through deepest Shropshire I came across a most magnificent ancient English Oak shown below.

I was keen to find out the age of this massive living thing.There is a method of estimating a tree's age by measuring the circumference of the trunk about one metre above the ground.By using a scale of 1 inch = 1 year an estimate of the tree's age can be derived.Unfortunately we did not have a measuring tape so we used our arms instead and arrived at a circumference of 240 inches which is equivalent to 240 years! So our oak tree was an acorn in the year 1775..........wow! What was happening in 1775? Magnificent trees like this one are part of our heritage and we must look after them.

I can't finish this autumnal blog without a few words about seasonal smells. Of late I have been enjoying kicking through piles of fallen leaves heaped about the woodland paths and tracks.I remember doing just this as a child and I still feel the same pleasure. Autumn scents are so evocative of childhood memories, especially the smell of a bonfire of dried leaves. Of course it is much more environmentally friendly to make a compost heap rather than a bonfire.

However, kicking through the autumn leaves releases lots of lovely scents into the air and this got me thinking about trying to describe the various smells that make up the scents of Autumn. If  the fragrance could be bottled like wine, how would it be described on the label.............................'handcrafted by mother nature over millenia to create a mellow fruitfulness.........with hints of over-ripe apples and crisp dry leaves.........overtones of mushrooms and wood smoke with a long damp earthy finish. Best enjoyed in season and an excellent accompaniment to a brisk walk before breakfast'.

Berries,Butterflies and Badgers

Rowan Berries

Along the wayside and in the woodland the Rowan trees are heavy with plump ripe red berries  providing a feast for the Blackbirds.2013 has been recognized as a 'Mast' year where plants have produced bumper crops of fruits and nuts such as acorns, blackberries, hazel nuts,apples hips and haws.The combination of the wet summer last year and the dry warm one this year are thought to be responsible.Not only will there be lots of apples and blackberries for us,but also for the birds,badgers,foxes,squirrels,mice and many others including insects.In the orchard, wasps and butterflies are feeding on the sugars of fallen,fermenting apples and plums.The generally warm and sunny weather of August and September has been kind to our butterflies trying to recover from the disastrous weather of last year.Still the white species predominate but other species seen include.....Red Admiral, Small Copper,Comma,Brimstone,Speckled Wood,Peacock,Painted Lady and Small Tortoiseshell.
Back in August I was fortunate to observe the courtship behaviour of the Small White butterfly.After alighting on a leaf wings open, the female surprised me by suddenly extending her abdomen upwards so that the tip was elevated about ninety degrees above her body as shown in the photo that I managed to take.

Small White Butterflies (male left,female right)

The male fluttering above her descended several times positioning the tip of his abdomen against that of the female.In that position sperm can be transferred and stored in the female ready to fertilise her eggs.Another remarkable fact I learnt about butterflies recently concerns the migratory behaviour of the Painted Lady. On it's spring   migration from  Southern Europe and Africa to the UK and as far north as the Arctic Circle,and the return autumn migration, this butterfly has been shown to fly at an average height of  350 m above ground level with some individuals flying at  an amazing altitude of 1 km!The incredible round trip of 9000 miles is under taken not by individual butterflies,but as a series of steps by up to six successive generations of butterflies.
And lastly I  discovered a hole in my lawn recently and initially suspected 'Peter Rabbit' was to blame.However, on closer inspection I noticed several dis orientated bumble bees crawling about in the hole whereupon my suspicions turned to another inhabitant of the Wild Wood. A large paw mark in the excavated soil confirmed my suspicions ........Mr Brock was the culprit! It is well known that badgers will raid bumble bee nests for their honey and wasp nests for the grubs.
