Teesdalian Botanophilia: Part Two

This is a follow-on from Part One here.

Widdybank Fell is spoken of in hallowed terms by botanists. A visit there was high on my list of must-dos in Upper Teesdale. The site is easy to access by road and there is a car park (but no loos or other facilities) at Cow Green Reservoir (Grid Reference NY810309).

Cow Green reservoir, so tranquil today, was the site of a bitter controversy back in the 60s. Upper Teesdale has internationally rare assemblages of alpine plants; remnants of a once more widespread post-glacial flora. Plans to construct the reservoir meant a part of this relic flora was to be inundated. Local conservationists fought a fierce battle to save the area, letters were written to The Times, scientific papers were published, ministers consulted, but despite all their efforts, the reservoir was built. Government 1: Rare Plants 0. However, the land surrounding the reservoir was designated as an NNR (Moor House and Upper Teesdale) and is now a Global and European Geopark.

Looking ahead is the dam, behind which is Cauldron Snout waterfall. The path to the dam is tarmacced and easy going. (From thence, the going gets harder; the 'path' down the water fall is a scramble over rocks so most people walk carpark to dam and back.) The plants I have photographed were all found just along or near to the path.

Widdybank Fell is a delectable feast of dainty delights. Consequently, much of my time was spent in the botanical position; head down, bottom up, with wet knees.

Adorable mountain pansies (Viola lutea) were dotted about in the short damp grassland.

Here's the petite pink bird's eye primrose (Primula farinosa); only found on limestone in upland Britain. Most plants were past their best but we found a few still flowering.

Another diminutive alpine plant (see UK distribution map here) found on damp calcareous upland grassland is Scottish asphodel (Tofieldia pusilla). Sowerby's English Botany (1799) states that it was first found in England in County Durham. Mr Thomas Tofield after whom the genus is named, was an 18th century botanist and civil engineer from Doncaster.

The tiny white stars of spring sandwort (Minuartia verna) were dotted about where underlying limestone rocks were exposed.

A plant I didn't expect to find in the mountains was sea plantain (Plantago maritima) with its distinctive yellow anthers and linear leaves. This photo (below) was taken leaning over a fence as they only grew in exclusion zones, fenced off from sheep. The exclusion zone was tiny and hinted at the botanical riches we could enjoy if grazing pressure was reduced.

Also growing in exclusion zones were carpets of alpine bistort (Persicaria vivipara). You can see its dark browny-red bulbils under the white flowers.

Woolly-fringe moss (Racomitrium lanuginosum) is characteristic of upland moors and below is growing with wild thyme.

The red spangly spoon-shaped leaves of carnivorous sundews (Drosera rotundifolia) sparkled in boggy areas. Drosera mean 'dewdrops'. They are always a treat to see.

On exposed rocks by the water we found yellow saxifrage (Saxifraga aizoides)....

Once past the reservoir dam, the footpath is rockier. The Tees tumbles noisily down the cataract of Cauldron Snout right next to the path.
It then flows over its rocky bed through open country. We didn't meet another person on this stretch of the path. 
There were scattered juniper trees (Juniperus communis) in the rocks.

Further along, a distinctly chubby viviparous lizard (Lacerta vivipara) was sunning herself on a short stretch of boardwalk. She'd clearly regrown her tail at some point.

I was thrilled to see ring ouzels along the way; here ahead of us on the path.

After a few miles we left the River Tees and started to follow the track back round to Cow Green. The picture below looks back to Widdybank Farm (reserve office for the National Nature Reserve/Natural England).
During our day-long walk through this beautiful upland area we didn't see a single raptor in the sky; not one. I thought this very suspicious, as the habitat seemed perfect. In fact raptorless skies were a notable feature of our entire week in Upper Teesdale.

The last stretch of the walk was along the road and the best views were to be had by looking backwards. Here is the view back down Teesdale with its white-washed farmhouses.
This fluffy juvenile wheatear was sitting on rocks near the car park. Cute!

  1. Marvellous.... just the kind of habitat I looked for when I was up in the Dales last (and failed to find because I hadn;t done my homework).

  2. You've sussed my secret. A bit of planning did help. M
