About this Blog

This blog reflects our twin interests in walking and natural history, especially botany.



"Ich wandle unter Blumen

Und blühe selber mit ..."

Heinrich Heine





Walking is important to us as a way of being in direct touch with the environment, experiencing species and habitats in their ecological and historical context. By walking between different flower sites we experience the character of the general countryside, getting to know as much where flowers are not as where they are. Walking allows for the serendipitous - chance encounters with animals, meetings with local people, unexpected species - which enrich the experience.

We set up this blog to share a variety of mainly day-long walks centred on "iconic" flower sites and locations of rare plants, where these are publicly accessible. The accounts include descriptions of the routes taken, key plants seen, other wildlife encountered, and anything of general environmental or historical interest. All the walks allow time for looking around (some flowers need searching for), photography etc, and usually include a half-way stop for refreshment at some suitable establishment. The walks are seasonal, depending on the flowering/fruiting times of different species, although one cannot hit the peak time for all species seen on one walk, and the best timings will vary from year to year. Lengths vary but the walks may be anything up to 12 miles or more, so an early start is recommended.



A certain knowledge of our flora is assumed, but those less familiar should be able to identify most of the plants mentioned with the help of one of the good field guides - Blamey, Fitter and Fitter Wild Flowers of Britain & Ireland (A&C Black) or Francis Rose The Wild Flower Key (Warne) - although occasionally recourse may be needed to more technical tomes such as Clive Stace New Flora of the British Isles (Cambridge) or the specialist volumes published by BSBI (Botanical Society of the British Isles) on grasses, sedges, umbellifers etc.



While examining plants it is interesting to note the galls, leaf-mines and fungi (rusts etc) that are often specific to particular taxa. For galls we use Redfern and Shirley British Plant Galls, for leaf-mines http://www.ukflymines.co.uk/ (which also includes lepidopteran and other mines), and for fungi Ellis and Ellis Microfungi on Land Plants, although this is a technical tome rather than a field guide.

Our completed walk around the coast and borders of England is described on http://www.coastwalking.blogspot.co.uk/ and our current walk around the coast of Wales is on http://www.coastwalkwales.blogspot.co.uk/

Berkshire: Windsor Great Park


7 May 2013                                                OS 175: Reading & Windsor
Length: half day.
We visited two sites - Savill Gardens for its naturalised daffodils, and Cranborne Chase and the open park for its veteran trees.  It is possible to walk between the two, although we drove separately to each, saving repetition of the walk back.
          The car park at Savill Gardens is signed from the main roads at SU977706.  There is an entrance fee, but the car park is free for the first 90 minutes.  We found we could walk round it in an hour.  In front of the Savill Building where the entrance and shop stand is a welcoming "Sedum roof" that at this time was carpeted with flowering stems of meadow saxifrage Saxifraga granulata.

After entry we descended the grass slope towards the lake.  On this slope a group of daffodils with 1-3 flowers per stem, of medium size, appeared to be the cultivar 'Sweetness' (see picture). 
'Sweetness' daffodil
 By the bridge over the lake we visited a bank with cuckoo-flowers Cardamine pratensis being visited at the same time by orange-tip butterflies, while dark alder flies emerged from the lake that had been the home of their larvae.  Here among field woodrush Luzula campestris and the leaves of common spotted orchid Dactylorrhiza fuchsii, there were plants of a pale purple form of wood anemone Anemone nemorosa, which can occur naturally, but may have been selected for this horticultural situation.  There were also many well-naturalised specimens of the miniature species Narcissus bulbocodium with its distinctive megaphone-shaped flowers, also known as the "hoop-petticoat daffodil".  These were scattered all across this bank and we were to find them similarly naturalised in many other grasslands in the gardens, particularly in the area beyond the lake called The Glades.  It appears that they seed and germinate readily, although native to SW Europe.  The Glades consist of a large meadow on both sides of a small stream where N. bulbocodium is rife, along with a few specimens of another miniature Narcissus minor.  It was pleasing to see a formal garden like this allow these species to spread and acclimatise, looking as though they were in their natural meadow habitat instead of a garden-bed, and this as a matter of policy.

 In the lake below flowered bogbean Menyanthese trifoliata and marsh marigold Caltha palustris, which may have been native to these waters.

In The Glades the N. bulbocodium was accompanied by bluebell Hyacinthoides non-scripta, cowslip Primula veris, and fritillaries Fritillaria meleagris, a good many the white form that hints that these, like the daffodils, were introduced, as the white form constitutes only a very small percentage of "native" or at least long-established populations.  Other introductions in this meadow are Erythronium revolutum, a lily with marbled leaves, and Asian skunk-cabbage Lysichiton camtschatcensis in the brook.  St Georges Mushroom Calocybe gambosa also grew here.

The other species daffodil long-naturalised in the Gardens is the cyclamen daffodil Narcissus cyclamineus, so named for its swept-back petals.  There is a large plot of this beyond the Glades as you approach the Spring Garden.  Unfortunately this plant had flowered much earlier and it took a diligent search to find one last fading bloom to photograph.
Narcissus cyclameneus
We completed the tour of the garden past the Queen Elizabeth Temperate House and back to the river and its lakes.  Striking plants included the following.
Rhododendrons augustinii cv 'Electra' (upper)
& 'Baden Baden' hybrid 'Essex Scarlet' x forrestii 'Repens' (lower)
Lily of the valley
Acer palmatum 'Dissectum'
'Salome' daffodil with pink trumpet
'Coleman Hybrid' daffodil
'Baby Moon' daffodil
'Toto' daffodil
 
Inside the warm Temperate House mossy clubmoss Selaginella kraussiana was spreading like a weed, although we did not see it escaped, as it does occasionally in the south-west.

By the stream American skunk-cabbage Lysichiton americanus is well naturalised, and we saw one small patch of blinks Montia fontana, quite possibly native.

As we returned to the entrance we noticed a fenced grass plot where another species daffodil was being naturalised, this time the multi-flowered creamy Narcissus triandrus from the Iberian peninsula.

We then drove to the car-park on the A332 at SU948727, opposite a pink lodge called Cranbourne Gate.  This provides access to a small part of the old woodland of Cranbourne Chase.  Immediately by the entrance to the car-park is one venerable pollard oak Quercus robur, over 700 metres girth, which is split but apparently in good condition.
 
 
There are similar pollard oaks all along this part of the A332, easily seen from a car.

Also near the entrance was shining cranesbill Geranium lucidum, but the ground flora in this area is generally poor with thin acid soils and improved grassland.

To the south more old oaks in various states of disrepair were visible in cow pasture.


In the semi-open woodland west of the car-park roamed cattle that looked very like the Chillingham breed, closest to the original wild cattle.  We also saw roe deer.

We followed a sandy riding track (there seem to be no footpaths) through the woodland, past a fine display of bluebells.

Most of the veteran trees here are oak, but we did see the odd beech Fagus sylvatica, hosting the common willow bracket Phellinus igniarius.

While the veterans are oak and beech, the younger growth trees are mainly sycamore Acer pseudoplatanus with hawthorn Crataegus monogyna scrub, while ash seedlings Fraxinus excelsior dominate the ground layer, showing a very different wood developing.  There were also some tall old apple trees, but Malus domestica, not the true crab apple.
Apple blossom
The riding track bent back round to the road opposite Rangers Gate.  We crossed the A332 here and found by the gate some clumps of early scurvy-grass Cochlearia danica, a sign of road-salting.  By the lodge was another impressive old oak.

We entered the main part of Windsor Great Park, an odd artificial landscape of straight hedgerows, wide grass rides with vistas and statues, improved grassland and intensively farmed fields, where the vegetation is very low in diversity, a landscape for riding and hunting rather than walking.  The main flowers in the low grass were dandelions Taraxacum officinale agg and the introduced slender speedwell Veronica filiformis.
 
Vista towards Windsor Castle along Queen Anne's Ride
We took the path to Queen Anne's Ride and up there to The Village, where grotesque lime-trees Tilia x europaea, much lopped and pruned against their natural growth, were festooned with large clumps of mistletoe Viscum album.  They stand near the Millstone statue commemorating the planting of 1000 trees along this ride in 1992, replacing veterans that were taken down because they looked decrepit, not recognising they were invaluable for invertebrates and fungi in that state, and even have a certain Gothic scenic value.
Mistletoe limes by The Village and the Millstone
We went east from this spot towards the 1829 copper statue of George III on Snow Hill.  We passed an excellent large veteran oak which was not far under 10 metres in girth.  The emergence holes in some of the dead wood showed that it was being well used by beetles.

Bark of the veteran oak
This route also passed some old hornbeams Carpinus betulus and some fragments of wood stained blue by the Green Elfcup fungus.  There was another long vista to Windsor Castle from the top by the statue.  We walked south from here and circled around the other side of The Village, sometimes with ring-necked parakeets flying over with their harsh cries, and occasional views of brown hare, pheasant and red-legged partridge.  From here it is just a short walk back to Cranbourne Gate.

Berkshire: Maidenhead Thicket & Few-flowered Leek


3 May 2013                                                OS 175: Reading & Windsor

Length: 1 hour.
 
We started from the car-park by the northern arm of Maidenhead Thicket (National Trust) at SU855816.  Across the road was an open access field carpeted with cowslips Primula veris, one of the best cowslip meadows we have seen, thick with vigorous plants.  This is Pinkneys Green Common, managed by the National Trust.

Cowslips, Pinkneys Green Common

 Having drunk in this spectacle - which is likely to be full of more flowers in the summer - we walked NW through the thicket to the north end and then followed the west edge southwards.  The wood is largely of young trees with occasional mature beech.  Plants common here are red currant Ribes rubrum, ramsons Allium ursinum in large masses but still only in bud, wood anemone Anemone nemorosa, woodruff Galium odoratum, spindle Euonymus europaeus, gooseberry Ribes uva-crispa, bluebell Hyacinthoides non-scripta, lesser celandine Ficaria verna, sanicle Sanicula europaea and our target few-flowered garlic Allium paradoxum.

 The few-flowered garlic, which happened to be in peak condition on this date, was concentrated down the western edge, sometimes spilling out of the wood into the grassland.  This must be one of the best places to see this plant in all its glory.  Most plants consisted of a head of bulbils with several white papery bracts, from which emerged one or two slender stalks with single small white bell-shaped flowers - few-flowered indeed.

Some plants of hybrid bluebell Hyacinthoides x massartiana near the car-park made us wonder about the origins of the flora in this wood.  The few-flowered garlic is certainly an introduction and can spread rapidly, ramsons is native but also occurs widely as a garden escape, and the same applies to many other plants here, such as red currant and gooseberry.  Others like sanicle and woodruff are almost certainly native.  However it got to be this way, it is still a great spectacle in spring.

 

Afterwards a brief drive took us to Burchetts Green SP840815 (walking there is awkward because of the intervening motorway).  Here an old American red oak Quercus rubra stands at the crossroads opposite the Crown pub.  It was just opening its bright yellow leaves at our visit.

 We walked up Hall Place Lane from the oak, leading to a path through playing fields to Hall Place College.  On the crest ahead stretches a line of limes Tilia x europaea with large bunches of mistletoe Viscum album, standing out dramatically against the sky.  They border the eastern road into Hall Place and were originally planted in the C17th, although many have been replaced since.  The usual bush of shoots at their base is kept cut, unusually revealing the trunk.

The former mansion is now a further education facility teaching a huge range of work skills from farming to hairdressing to dog-handling and the park makes a very pleasant milieu.  A range of daffodils has been planted along the road verges.  We did not stop to identify most, but we were struck by the cultivar 'High Society', which has a trumpet which is pink, white, yellow, then green inside.

Berkshire: River Loddon & the Loddon Lily


30 April 2013                                             OS 175: Reading & Windsor

Length: half day.
 
This walk was essentially all about the rare Loddon Lily Leucojum aestivum, which is either native or long-established here along the Loddon and to a lesser extent by the Thames, although it occurs elsewhere casually as a recent garden escape.
 
We started at the car-park of Dinton Pastures Country Park just east of Reading SU785717 (just £2-40 all day).  The park was busy with dog-walkers, joggers and groups of walkers of all kinds.  With it being a sunny spring day after a long winter, flowers, bee-flies and butterflies (most of the spring species including holly blue) were out in quantity.
Comma on its food-plant

 We took the path west along the south side of the park, heading straight for the River Loddon, which forms its western boundary.  We passed some indigenous wood-carvings of a bird and snail.


Bluebells Hyacinthoides non-scripta were just out - our first of the year; lesser celandine Ficaria verna, garlic mustard Alliaria petiolata, greater stitchwort Stellaria holostea.  Many trees and shrubs were flowering: blackthorn Prunus spinosa, Norway maple Acer platanoides, field maple Acer campestris, ash Fraxinus excelsior, wild cherry Prunus avium.

By the streams, lakes and pools (these are former gravel workings) great pond sedge Carex riparia and hemlock water dropwort Oenanthe crocata were common.  At the first lake, ducks and geese congregated around the interpretation board where there was obviously regularly feeding.  They were largely mallard, Canada geese, Egyptian geese, coot, mute swans, herring gulls, tufted duck, a few gadwall, great crested grebe and a possible melanistic mallard.

Freshly-opened cuckoo-pint Arum maculatum posed for a picture and could not be refused.
 
When we reached the river, we first saw ramsons Allium ursinum on the banks, the flowers still in bud, wrapped in a white cowl, but soon afterwards we began seeing clumps of Loddon lily and these were at a perfect stage in their flowering season.  We saw these scattered the whole length of the river on both sides between the southern and northern boundaries of the Country Park.  Reminiscent of snowdrop with the green spot on their petals, most spikes had 2 or 3 bell-shaped flowers which hung their heads demurely.  The rare flower that happened to be gazing upwards revealed the striking orange anthers inside which normally remain unseen.

We explored the east bank and then crossed the river by the bridge at the south end of the park to follow the west bank north.  Where mud had been dredged from the river there were bleached remains of the River Snail Viviparus viviparus, restricted to major rivers like this and the Thames, and Swollen River-mussel Unio tumidus.  Deep in the stream could be seen the large submerged leaves of fringed water-lily Nymphoides peltata.

          After diverging from the river round a large field, we followed a path through an equally large marsh.  It was fortunate that the path was concreted here because the water was very high in the centre, coming over our feet, and it would otherwise have been difficult getting through.  It led to a rather decrepit wood (Sandford Mill Copse?) with some old trees that looked as though it had seen better times, but by going right at the entrance through fallen wood debris we came across a swamp with thousands of Loddon lilies crowded around, the largest colony we found (see picture).
 
 
Although neglected and with some rubbish, this copse also contained wood anemone Anemone nemorosa, primrose Primula vulgaris and moschatel Adoxa moschatellina.  Some of the latter had distorted stalks and the silvery spore-capsules (sori) of the fungus Puccinia adoxae.

Old willows had the common bracket fungi Willow Bracket Phellinus igniarius and Blushing Bracket Daedaleopsis confragosa.

At the top of the wood (having found the right route among the meandering paths) we were confronted by the apparent wreck of an aeroplane!




Having found a way around to the other side we discovered the Berkshire Museum of Aviation.  There were a couple of outside exhibits and much other stuff inside a hanger, but it was currently closed.  Just inside the fence by the entrance were the dead seed-stalks of tower mustard Arabis turrita, reportedly transferred here when land nearby where it grew was landscaped for the museum car park.  On a barish grassy bank opposite the entrance grew early forgetmenot Myosotis ramosissima, cornsalad Valerianella sp, thale cress Arabidopsis thaliana, common whitlow-grass Erophila varna, parsley-piert Aphanes arvensis, field woodrush Luzula campestris and leaves of tansy Tanacetum vulgare.

Nearby were garden yellow archangel Lamiastrum galeobdolon montanum, garden grape hyacinth Muscari armeniacum, honesty Lunaria annua, purple and white forms together, and curly leaves of crow garlic Allium vineale.

Honesty in purple and white forms

The museum has access to the lane from Reading to Sandford Mill, which we took past the latter, where a dell below the road as it passes over the Loddon had more Loddon lily, ramsons and marsh marigold Caltha palustris.  The bridge itself supported hartstongue Phyllitis scolopendrium and common mosses, while shiny cranesbill Geranium lucidum was common in the verges.

Just over the second bridge a path goes left along the east bank of the river again.  (Another path across the road re-enters Dinton Pastures just where there is a large bush of wild plum Prunus domesticus in full flower, with the leaves unlike blackthorn.)

Wild plum

 Back beside the river we saw alder-fly emerging and passed the corpse of a common shrew (these creatures always seem to die in mid-path).  From a bird-hide we could see across another of the gravel-extraction lakes where there was a narrow island adopted by a group of cormorants.  Other birds were great crested grebe, lesser black-backed, black-headed and herring gulls, Arctic terns, and moorhens.  A fox was scouting the far bank, perhaps looking for accessible nests to raid.  Frequent along the well-vegetated banks were the clambering vines of hop Humulus lupulus. 

River Loddon

At Whistley Mill a heron was fishing beside the wide old mill-pool.

The riverside path ends here and we had to divert westwards and then north along a wide track through more lakes reserved for angling clubs and protected by high fences, spoiling the experience for walkers.  Goldilocks buttercup Ranunculus auricomus was frequent on the pathside, and occasionally water chickweed Myosoton aquaticum. 

Goldilocks buttercup

 After passing underneath the main Paddington railway we were in Berks Bucks and Oxon Wildlife Trust's Loddon Reserve, with much planted western balsam poplar Populus trichocarpa with fresh bright green leaves and red currant Ribes rubrum.  One path rejoins the Loddon, where the banks were full of comfrey Symphytum sp not yet in flower.  In wet hollows was more Loddon lily and marsh marigold.
         The path eventually leads to the road on the west edge of Twyford, where we found a café for a snack.  Alongside the main road, between the pavement and a cottage wall were a few plants of early scurvy-grass Cochlearia danica.

Early scurvy-grass in Twyford

 This walk could easily be foreshortened by returning through Dinton Pastures after Sandford Mill (past the wild plum) without missing much of consequence and having seen the best the Loddon lily could offer.  By the car-park is a café that might then be useful.
         We afterwards drove to the pleasant old town of Wallingford and walked up the west bank of the Thames north to opposite Preston Crowmarsh, a place where Loddon lily has also been recorded, but we only found two well-separated plants and the banks were too built-up and bare to provide suitable marshy habitat.  However, we did find flattened meadow-grass Poa compressa and Mexican fleabane Erigeron karvinskianus growing on Wallingford bridge and saw mistle thrushes feeding in the grassy parkland beneath the bridge, while beside the street from the bridge into town was rue-leaved saxifrage Saxifraga tridactyla.
