|Black Poplar Planting||We are indebted to Roger Jefcoate CBE for providing this black
poplar cutting which we hope will take root and grow to rival the
champion black poplar in Brecon which at 110' high by 90' across is
our largest native tree. This is Populus nigra ssp betulifolia, our
rarest native tree, not to be confused with hybrid black poplars.
We chose a male so as not to inflict the floating seeds on local
asthma sufferers. We planted this at the bottom of the playing
field while our President, Sir Angus Stirling and a number of
Friends applauded. Mr Jefcoate also gave Graham Vincent three
further cuttings to grow on and plant where appropriate. The
Kensington News and Post has promised to carry a piece about the
planting. [Winter 2007]
|Pink Palms, Porcelain and Poached Eggs||
The slimy Beech Tuft, affectionately known as the Poached Egg Fungus, scientific name Oudemansiella mucida, emerges from the heartwood of the trunk where it has likely lain dormant. The peculiar dark hue of the fallen logs points to this. An infestation of the living tree by air borne spores getting into a wound could cause the tree to tumble down in strong winds – all parts of Nature's mysterious ways.
"Every cloud has a silver lining" is a traditional British saying reflected here by the stormy weather this year when many favourite mature trees in Holland Park crashed down. Soon, fresh gaps became familiar views; logs rotted in artistic piles – testaments to those former glories.
As Autumn arrives, however, sorrow for our fallen giants is replaced by a lightning jolt of wonder when the beech logs near the Northern Enclosure crosspaths magically sprout a truly spectacular display of shining ivory white fungi, a gleaming mass over the rotting logs, a lively resurrection.
Thick tufts of elegant mushrooms, technically "sporophores", with gelatinous caps, like lightly poached egg white in texture, with a diffused flushed centre, mature in varying stages, starting as a mass of pearl-like immature buttons pushing forth from the mycelium mass.
The maturing spherical cap broadens out to a mutch-like shape, ragged at the edges and diaphanous like a small white jellyfish, flattening out further to a saucer-like shape. It is a beautiful clear white, the fawn held up to the light, hence its alternative name : The Porcelain Fungus.
The veil enclosing the immature egg-like cap disintegrates leaving a slight ring around the tough, strongly rooted stipe, while the bone china white gills are widely spaced shedding white spores. The fungus will gradually break down the log performing its unique role, in its unique niche, in the ecological re-cycling by Nature.
Another very beautiful fungus feeding off fallen elm appeared this autumn in Holland Park. The striking Rhodotus Palmatus is an unusual fungus, in a class all of its own. With an apricot-tinted cap, it looks like a soft, ripe apricot, from a distance, - and even has a distinctive perfume of apricots!
The cap has an unusual detachable glutinous cover, wrinkled in a
curious maze-like pattern. Strange rose-red droplets lied in tiny
typical pittings of the cap and pinkish-white, often excentric,
curved stripe. The spores are uniquely pink and spiny. As it
matures, the cap lightens in colour, especially if washed out by
rain, becoming concave, to resemble a pink palm, as its name
reflects, from palmatus, Latin for hand-like.
An excellent photographic field guide published as a joint project by Collins Natural History and The Wildlife Trusts describes the distribution of Rhodotus Palmatus as "Uneven"; its scarcity as "rare to very rare"
Stunningly attractive fellow travellers appearing mysteriously in the moisture and warmth of sunlit groves in Holland Park to "walk with us" for some fleeting days along the same path of life, they are also both valuable companion rotters of the very best kind!
NB : It must be stressed that eating fungi from the wild is potentially lethal so must be seriously avoided without truly expert identity guidance.

|Trees, trees, trees||
The Borough, by which we mean largely the Ecology Centre, has been very busy drawing up management plans. While there is always a temptation to think that time would be better spent on practical matters, it has to be admitted that the Friends have long asked for better planning and therefore welcome this activity.
We have been consulted on the draft of RBKC's Local Biodiversity Action Plan 2007 - 2011. This is a document that descends from an international convention in 1992 via UK and England plans to Borough level and is concerned with maintaining and improving biodiversity of all life forms. There is an emphasis on native plants and it is true that aliens such as Japanese knotweed and grey squirrels can do immense damage, but, as any gardener knows, slugs are not particular about the provenance of their breakfast. So the contribution of a plant to biodiversity should be measured by its usefulness to other life forms: we can with a good conscience both plant native trees and expand our collection of exotics.
The LBAP covers all parts of the borough, parks, woodlands, cemeteries, riverside, private gardens and waste ground but we are concerned with the first two. Habitat preservation and improvement is of the first importance to nurture desirable species. There is a clear message that biodiversity needs to be considered throughout our parks and not confined to designated "wild" corners. Hence the borough's unwillingness to use weed killers and pesticides even in formal gardens.
The borough produced a Tree Strategy in 2005 which has a brief section on trees in parks and especially Holland Park but for any detail we need to go to the HP Woodland Management Plan 2006 – 2011, covering the northern enclosures (but not the Oak Enclosure, the Arboretum or the path verges). This is still in draft form and a further Tree Plan has yet to be produced. The Friends have been consulted about the Woodland Management Plan and we are especially pleased to see that the draft acknowledges that one of the major objectives is "to preserve the tranquil and natural atmosphere of the park". We are also pleased that, following our representations, it is now agreed that one of the historical reasons for the woodland creation, namely screening from the world outside the park, is still relevant. This is especially important in view of the uncertainty regarding the school site and other developments. The draft includes "prescriptions" for managing each enclosure, thinning some, thickening others, maintaining on the whole desirable exotics within them but removing invasive species and planting natives.
When we include those gaps where trees have been blown down in recent gales, it looks as if there will be a good number of replacements needed and the park will be grateful for gifts of trees. To ensure that these contribute to the overall structure of the park, it has been agreed that we will draw up a list of required species and locations and donors will be invited to choose from that list. Native trees for the enclosures are likely to include hornbeams, sweet chestnuts, sessile oaks and broad leaved limes. There will be scope for exotics along the verges and maybe in the Oak Enclosure and the Arboretum. Horse chestnuts are unlikely to be approved while the leaf miner is so disfiguring but many chestnuts are distasteful to the miner including the fast growing and very decorative Indian Horse Chestnut.
The borough has procured a handsome book with loose-leaf pages
where donors can have gifts recorded with details of names and
occasions as they desire. The plan is to have it on display in a
glass topped case, where one page at a time can be seen by the
public, perhaps in the cafeteria or park reception, and from where
requests to see specific pages can be allowed.
The Friends' contribution to all the planning has been advisory but we have also done practical work on trees this summer, mainly in the form of producing a tree walk booklet in conjunction with the Ecology Centre and with input from other borough departments. This is a handsome production that will be on sale from the park open day on 2 September. The core of it is a self guiding walk formed from a list of 48 notable trees. Each tree is marked on a map and has a drawing of a typical leaf and sometimes another feature. The drawings are by a professional botanical artist, Nina Barranca, who is also a Friend; we are sure you will all admire them for both accuracy and beauty. Letta Jones, a garden historian, has written an historical introduction linking past plantings with the topography of the park today. Rhoddy Wood, advised by Dr Alan Harrington, has provided descriptive paragraphs for each tree.
The Friends have borne most of the cost of producing the 36 page
booklet but decided we were doing it as one of our aims - "to
educate the public in the history, natural history and other
aspects of the park". To enable it to reach the largest possible
readership, we are therefore selling it at the heavily subsidised
price of £2.00. Please do support us by buying a copy and then have
fun using it.
A Friend, Andrew Whiteley, is making a check list of all the tree species in the park. He has read all the back issues of the newsletter and received botanical and historical guidance from Alan Harrington and Rhoddy Wood. An enormous amount of work later, his database is nearing completion. It now contains approximate locations for more than 400 named trees from about 250 species and a few more whose identification is not yet certain. He is passing this to the Ecology Centre where it can be used in conjunction with the Tree Plan.
One of the delights of walking in the park is never knowing when
something new will turn up. So the participants on one of Alan
Harrington's tree walks on the West Lawn gazed in amazement at a
large shrub covered with red and yellow velvety fruit like lumpy
misshapen pears. In the excitement of the moment someone even
suggested cashews. Though this was quickly withdrawn, it does show
how we believe anything is possible in Holland Park.
We owe our tree to Nick Bentley, an erstwhile Arboricultural
Officer for RBKC. Nick now runs his own tree company and does some
work on tree maintenance for the park. One of his other clients
asked him to remove a Chinese cedar and he immediately thought of a
good home for it. Thank you, Nick. [Autumn
||It is a rare event in Holland Park for any of our peacocks to
lay eggs and bring off a brood of chicks, but this year it has
already happened twice and one of the peahens is presently sitting
on another clutch. Judging by the way the male peacocks display to
any passing pigeon, one might have given up hope that they would
even recognise a peahen! The five young birds are being cared for
in a special enclosure until they are old enough to be freed into
the Park. Seemingly peacock parents are not very expert in bringing
up their young. Perhaps they just don't get enough experience. [Autumn 2007]
Readers of the summer issue will remember that we were hoping to
be given black poplar cuttings to be planted in the park. This is now
confirmed for about 11.00 am on Monday 5 November. To honour the
return of this native, do come to watch the unusual planting
method. We will gather at the bottom of the sports field near the

gave Park visitors a fascinating display and explanation of
falconry with their large collection of falcons and owls. Our photo
shows a White Faced Scops Owl. [Autumn
|Swift boxes||If you have passed by the clocktower above the mural arcade in
the early morning or evening this summer, you may have been
mystified by the distinctive sound of swifts flying overhead while
being unable to see them. It is all part of an experiment to
attract swifts to nest in Holland Park. Suitable nesting sites are
now in short supply in London and swifts need encouragement to try
new locations. Nesting boxes have been installed within the
clocktower. To attract passing swifts to come down and have a look,
recorded swift calls have been broadcast from the clocktower. It
may take several seasons to judge whether the experiment has
worked, but now you are in the picture you too will be amused to
see people staring up into an empty sky, baffled as to where the
sound is coming from!
Ian Thomson showed us three newspaper pictures of our heron in
the Kyoto Garden. We would have liked to reproduce them for you but
the copyright is with Reuters whose fees are beyond us. The first
showed the heron alert on the bank, the second in the water with
his beak enclosing a koi carp and the third with his head up, the
fish firmly held and about to be swallowed. It is difficult to tell
exactly how large the fish was but certainly no minnow. We still
believe that the largest size we have of koi carp is too big to
swallow but we many have difficulty in growing fish to this size
while the heron is around.
Never say this newsletter has no influence! In the last issue, we wrote about how we hoped to replace some of the hybrid poplars lost in the January gale with native black poplars. One of our members copied this to a black poplar enthusiast who regularly roots cuttings and has now offered us at least one young tree together with information and advice. He listed an impressive number of prestigious sites, including Hyde Park and Buckingham Palace, where his trees had grown and flourished. It seems that the native is not so dependent on a moist site as we had thought but does like an open position. So positions in the woodlands would not be suitable but the edge of the playing field would be. Our first choice will be at the bottom of the sports field where in time it will grow to screen whatever is erected in place of, or in addition to, the Commonwealth Institute.
Our sincere thanks to our member for his initiative and to the enthusiast! [Summer 2007]
|Gales & Black Poplars||
He huffed and he puffed and he blew the house down – or at least 90 mile gusts on 18 January blew down a number of trees; Kew and Holland Park were both closed for fear of accidents. We lost seven large trees, all uprooted and displaying surprisingly small basal plates. Perhaps the saddest casualty was not one of these but a Hupeh crab damaged by a falling Robinia; the crab has had to be trimmed to a bare trunk of maybe twenty foot. Before that its white cloud of blossom peeped over other trees surrounding the West Lawn and was just visible from the steps to the Kyoto Garden. It was unusually tall for a Hupeh crab (the two by the Kyoto Garden entrance are of a more standard size) and Alan Harrington had recently suggested we should investigate whether it qualified as a champion tree. No more. We can only hope the stump may sprout.
|A Hedge with Two Faces||
Following our long hot summer of drought, autumn came early in Holland Park and with it many weeks of leaf clearance. The borough has imposed a ban on the use of mechanised blowers in the park (to minimise noise and pollution) and so we are back to using brooms to clear the paths. For weeks this seems like a never ending task and we pray for strong winds to bring down the remainder and help us win what seems like a losing battle!
Please contact Rhoddy Wood if you would like to see a complete list of the hedge species.Stella Fear
