Warning – trees in danger

A report out recently from the Forestry Commission (See Guardian 31 October 2012) warning of the prevalence of fungal diseases affecting a range of native UK trees, will not come as a complete surprise to anyone walking in the Thornthwaite Forest vicinity.

Last year I was warned that larch forests were at risk from a fungal infection and as a result the Forestry Commission was having to cut down a three acres site above the footpath that leads across the fields from Thornthwaite to Braithwaite.

Now even more serious is the threat to the native English ash tree, which could be decimated if the spread of the ash dieback fungus, appearing last month in East Anglia, is not stopped. The cause appears to be unregulated importing of plants from other countries. The Government needs to act soon to address this serious threat to the countryside. Spread the word if you can.

One positive development to note (See story in Guardian, 29 October 2012) is that a group of academics and developers has just developed an AshTag app for smartphones, which will allow users to send details and photos of suspected examples of the fungus (the leaves of the ash droop and go black) to a central point for the Forestry Commission to investigate. It’s a great example of crowdsourcing to deal with a potentially country wide problem and the app is from today available for download by clicking on the AshTag app website.

Rain forecast: stay inside?

You know the scene, only too well these days! You’re inside the house and have finished off a job, sent off some emails and now want to go to the shops, stretch your legs in the park, go biking or have a short fell run up Cat Bells above Derwentwater.

You put your hand out of the window. Is it spitting or just my imagination? You go outside and see a lot of clouds. Which way is the wind blowing? Will it pass over? Do I need a cag? How long have I got before the rain starts? The usual questions.

Well this last week, while we’ve been on the US west coast in Seattle, we’ve been introduced to the answer! It’s a new app for iPhones and iPads called Dark Sky. The design and a display are shown in the illustration opposite.

We were out in the city’s Discovery Park last weekend, with an overcast sky. Rounding a bluff as we reached the shoreline of Puget Sound, I asked my daughter ‘Is it going to rain?’ Pulling out her iPhone, she said ‘Hang on a moment. Yes I have it now. It’s saying could be sprinkling coming’. Thirty seconds later we felt the first drops! Amazing and it wasn’t the only time this happened.

The app uses GPS information for your position and deploys weather radar data and some sophisticated software and algorythms to predict type, extent and timing of the rainfall. It does not attempt to predict weather over more than one hour in advance. It is not clear how accurate it will be in very mountainous terrain where weather patterns can change very fast and unpredictably. The app was developed by a small company, kickstarter.com with financial backing from 1200 people. A detailed account and visualisation by the developers of what the app does can be found here.

It’s a must have app, but there is a snag for anyone outside the USA. It depends upon the developers getting the weather radar data, which can involve detailed and legal issues with individual countries. They want to extend the app for wider use and invite people to indicate an interest in getting the Dark Sky app in their own country.

Harnessing waterpower

With heavy storms and 6 cms of rain predicted, you’re most likely this weekend to have been thinking of flooded towns, marooned houses and spoilt travel plans. Essential for life, water can also of course destroy. Torrential rivers, tsunamis, melting icebergs and rising sea levels pose huge problems and threaten lives.

But these last two weeks I’ve been intrigued by two apparently unconnected examples of how the power of water has been harnessed to improve living conditions, grow produce or promote new industries.

The Romans were famous for their aqueducts, which were illustrated in Vitruvius’ treatise De Architectura, the only surviving book on Greco-Roman building techniques. Written between 30 – 20 BC, it was rediscovered in 1414 by the Florentine, Poggio Bracciolini; and was discussed recently in Melvyn Bragg’s In our time Radio programme (15 March 2012).

On a walking holiday in southern Turkey this month, we climbed on the hills above Patara, an important Lycian seaport c 120 BC in Roman times and had the opportunity to explore a huge aqueduct there, made up of hundreds of massive precisely shaped square stone blocks. (See top photo)

Their ‘cuff and sleeve’ design for each stone, which involved the male end of the first stone entering snugly into the female cuff end of the second stone and so on down the chain, enabled the Romans to transport via a syphon system over undulating land, huge quantities of water from the hills down to the port. (See second photo)

The surprise came this last week while I was doing some clearing at the top of the garden at The Larches.

Just over the wire fence behind the seat on the Buena Vista crag, I noticed a rounded moss covered shape on the ground.

Investigating further with a spade and brush, I discovered within a few minutes two lengths of cast iron pipe. Each one was 12½ feet by 12 inches diameter, with virtually the same cuff and sleeve design we had seen in Turkey.

I had known there had been been a pipe line from the old dam at the top of Comb Beck from sections I had seen further down the valley. This had been used for the Thornthwaite Lead Company’s mine at the bottom of the road and had been built in 1908.

Later in the 1930s when the mine was closed, the water pipe was used to power a small hydro-electric scheme for people living in Seldom Seen.

It’s fascinating to think that technologies developed by the Romans almost two millennia earlier were being used a century ago to develop new industries here in Cumbria on our doorstep.

Pity the South!

The sun may not be shining every day here in Keswick, but there’s been little rain and plenty of opportunity for us to be working on the garden and getting out on the hills. Today we had a beautiful Lakes morning with the sun rising over Latrigg against a blue sky.

A marvellous slew of colours too from the flowers and rhodedendron. It’s a joy to be out and what better place for us to have an early breakfast than on the Belvedere deck, as this morning’s photo shows.

The temperatures has not been what we would hope for near midsummer’s day, but compared to what we are seeing every night on the TV of the storms and flooding in the south of England, the North West is the destination to be heading for this summer and the coming holidays!

And if you make it up to The Larches this year, just look at the view of the Skiddaw range (below) from the Buena Vista Crag. You’re tucked away there and unseen at the top of our fellside garden; and if you don’t feel like making it to the top of the fells, you can always from the comfort of the seat travel the footpaths with a pair of binoculars!

C2C bikers check-in for lunch

We have had three C2C visitors this last week stopping by at the cottage on their way across the country on the marvelous coast to coast bicycle route.

Ian and Greg, good friends and former colleagues of mine at the WEA had with Les set off at 8.30 in the morning from St Bees on the Cumbrian coast and arrived, muddied and wet, at The Larches bang on time as predicted four hours later for a hearty lunch of soup and sandwiches.

We had pressed them to stay over for the night but 30 miles on the first day was too slow for an intended two day crossing, which was to land them up at Tynemouth on the east coast.

By the end of the first day they needed to have done 40 more miles and crossed the M6 to reach Great Salkeld beyond Penrith.

They were still arguing as they left about the exact distance they had to travel! But did not dispute that it was somewhere between 125 and 140 miles. Good going we thought for two days, particularly as they had to cross the high country of the Pennines via Consett in County Durham. Some stiff hills there!

The Larches is less than 300 metres from the C2C route, which cuts down through the forest from the Whinlatter pass and the Visitor Centre to reach the Thornthwaite road. It’s an excellent stop off for C2C bikers but is a good base too for anyone interested in road and track cycling in the northern lakes.

It’s also only ½ mile from the start of the Altura cycle trails through Whinlatter Forest, regarded by many as the best in the country. The garage provides good storage facilities for bikes and equipment. The photo opposite shows Ian in the garage after the bikes had been brought in from the rain.
