18/9/10: 'The Old Orchard' south of Hall Place, east of the A2

Another visit to the scrubland south of the railway track that runs past Hall Place, on some maps called the 'Old Orchard'. I spent a bit of time here watching the trains go by when I was a teenager. In those days (the mid 70s) people used to dig here for old bottles, so I presume it was a Victorian rubbish dump. Now it has a diverse - if somewhat eclectic - flora with large bushes, medium-sized trees and some areas of thin soil, sparse vegetation and rubble, backed by oak woodland on what I assume is the southern valley side of the River Cray floodplain.

Noticeable today - having 'clocked' it for the first time on a recent LNHS trip to Bookham - was a lot of Red Bartsia, a plant I've not found in Bexley Borough before. There were still a few flowers hanging on.

There were Common Toadflax, a few pale cream Lucerne x Sickle Medick hybrids, two Asparagus, four Lesser Swine Cress, Hop and a lot of Common St. John's-wort, the latter in flower. A single, 'dwarfed' plant of Upright Hedge Parsley was found in a rabbit-grazed patch. Other singletons were a Hoary Ragwort and a Vervain. A few Marjoram plants were still in bloom, both pale purple-violet and white variants. Geranium rotundifolium was noted, and several Geranium pyrenaicum occurred along the track between the railway and pumping station towards Crayford. Shrubs included a Spindle, Dogwood and Sloe. Field Maple was also present. A few clusters of fungi were also noted.

Subtle colours of some fungal fruiting bodies

Deciding to explore more of the site than previously, I eventually headed up a track at the west end of the site, parallel to the A2 Rochester Way (which veers slightly more westward as the Dartford by-pass), which eventually led to a scrappy industrial site at the southern end of the remains of the original Rochester Way. A large White Poplar had fallen across the track, which was bordered on each side by non-native, planted shrubs and trees - including saplings of False Acacia and Tree of Heaven.

Towards the industrial estate I found some open ground smothered in Common Stork's-bill. There were also several Wild Parsnip and some Soapwort. Just before the estate were a couple of suspected non-native grasses and, the the northern end of the old Rochester Way, some Ribbed Melilot.

Looking rather like reed Canary Grass, the flowers of this largish unidentified species were far spikier

Round the corner, by the road into the industrial area, were Small Ranunculus moth caterpillars on Prickly Lettuce.

By poking about in an unpromising-looking, shady, shallow sandy pit where rubble etc. had been dumped some time ago, I found a single plant of Stone Parsley which I believe to be uncommon in the Borough, also Greater Celandine and the herbs Spearmint, Lemon Balm and Feverfew.

Further on was a larger, open sandpit with a couple of Vervain, some Wild Carrot, a few Sheep's Sorrel and a self-sown Snowberry.

After some more persistence I came across an out-of the-way track atop a south-facing steep sandy bank, overlooking a housing estate. This had several large Broom plants on it, and most interestingly, it was smothered with Hare's-foot Clover, a definite London rarity, and also lots of mining bee nests holes. A good end to the afternoon, by which time there wasn't enough light to take a decent picture on my mobile phone camera.

11/5/10: River Cray / Thames Road Wetland

Another river clean-up bash today.

4 Chiffchaffs heard along By-way 105. A male Blackcap later seen by the Willow Carr here, and a Wren on the north bank of the river.


The crucifer Barbarea sp. (above) in flower here (and another by Footpath 106)


2 Caper Spurge (Euphorbia lathyris) in flower on the river bank by Footpath 106


Thames Road Wetland (TRW) looking north

TRW site species noted today included:

A pair of Dunnock
2 Coot and 2 young
Good (and first) views of Reed (or Sedge) Warbler here, amongst the Reedmace. Have got a sound recording which I need to run past an expert for a definitive ID .....
Harlequin Ladybird
Water Figwort

Lots of Slender Thistle
Bird's-foot Trefoil in flower
The poppy Papaver rhoeas (white sap)
Buck's-horn Plantain
Geranium rotundifolium
Weld
seedlings

On the Sewer Embankment:

Lilac in flower

19/7/09: Finsbury Park flora: from Fig to Zigzag Clover

FINSBURY PARK is in the London Borough of Haringey, close to Hackney and Islington.

The Park is a Site of Nature Conservation Importance Grade II. The most interesting part, from a wildlife point of view, is Parkland Walk, which borders the railway line along the western margin - running along the eastern side of the East Coast Main Line. It is a Local Nature Reserve and an Ecological Corridor.

A report and pictures of some of the flora follows. It's a pity nothing is made of the wildlife value in the park guide downloadable here:

http://www.haringey.gov.uk/index/community_and_leisure/greenspaces/parks_and_open_spaces_parks_facilities/finsburypark.htm


According to the Management Plan that is also available here 'The Parkland Walk Local Nature Reserve is a footpath and cycle path running along the disused railway line from Alexandra Palace to Finsbury Park. [It] has been completely re-landscaped as part of the [park] restoration project. The area underwent complete site clearance and infill and mounding was achieved using the dredged material from the lake. A new footpath and cycle path was ..... constructed and native trees, meadow grasses and flowers were introduced.'

The walk starts at the Stroud Green Road gate by the railway bridge. Here a probably 'self-sown' Fig (Ficus carica) was holding its own against planted Berberis.

View of Parkland Walk looking south towards Finsbury Park station. Thinner (apparently stonier) soil in the centre, looked like former railway track bed.

Looking north across characteristic vegetation of Mugwort, Bird's-foot Trefoil, Yarrow, Ox-eye Daisy and Clovers.


Many of the other species found are common components of vegetation assemblages around where I live in Barnehurst (SE London), including Field Bindweed, Ribwort Plantain, Teasel, White and Red Clover, Lesser Trefoil, Black Medick, Spear Thistle, Evergreen Alkanet, Bristly Ox-tongue, Old Man's Beard, Broad-leaved Everlasting Pea and Creeping Cinquefoil.

LASHINGS OF LEGUMES

This Spanish Broom (Spartium junceum) might be self sown, or may have survived removal of some shrubs due to anti-social behaviour problems (there's a reference to this development in the Management Plan). There's a patch of Comfrey behind it on the left. Contrast the bank with the mown grass beyond.


At the top of the bank above this were three plants of Tufted Vetch (Vicia cracca)- the largest seen here to the right of a Creeping Thistle.


A highlight, given I've been looking out for it everywhere I've been lately (with no success hitherto), was this solitary specimen of strongly red-purple flowered Zigzag Clover (Trifolium medium), growing amongst White Clover and Bird's-foot Trefoil.


This Tall Melilot (Melilotus altissima) was only 6" high, presumably struggling in very poor soil.


Inside the railway fence, heading north, were several Goat's-rue (Galega officinalis).

At the far north end of this part of the site, on a bank to the right of the footbridge over the ECML, that accesses the continuation of the closed Alexandra Palace branch, were several Lucerne, this one growing next to Weld.


LIMITED NUMBERS

Also here was a fine patch of Common Toadflax


Other species found in very small numbers included Silverweed, Black Knapweed (2 - but may have been more that were not in flower and thus overlooked), Musk Mallow (a few inside the railway fence) and this Vervain (only one found - a very wiry plant that doesn't show up well in the photo).


More typical was Yarrow against a backdrop of Mugwort and grasses, with Ribwort Plantain seed heads - a pleasing symphony of green and white.

If you find yourself at Finsbury Park with an hour to spare, go and have a look.
