Eel-Grass Family:-

Eel-Grasses or Grass-Wracks are " the only flowering plants that grow completely submerged in the sea, looking at low tide like patches of grass or green seaweed. Unlike seaweeds, however, they have roots. They are all perennials, with alternate, long, narrow, grass-like leaves. Their inconspicuous flowers are petalless, and reduced to 1 anther or 1 style with 2 stigmas, alternate in 2 flat rows, partly enclosed in sheaths, towards the bottom of some of the lower leaf-like branches. Male and female flowers are separate on the same plant." from Collins Pocket Guide to Wild Flowers by David McClintock and R.S.R. Fitter assisted by Francis Rose - ISBN 0 00 219363 9 - Eleventh Impression 1978

Jellicles Part 3

Old Possum's Book of Practical Cats by T.S. Eliot, Second Impression published by Faber and Faber Limited in November Mcmxxxix.

The Song of the Jellicles - Part 3:-

• Jellicle Cats come out to-night,
  Jellicle Cats come one come all:
  The Jellicle Moon is shining bright--
  Jellicles come to the Jellicle Ball.

Jellicle Cats are white and black,
Jellicle Cats are of moderate size;
Jellicles jump like a jumping-jack;
Jellicle Cats have moonlight eyes.
They're quiet enough in the morning hours,
They're quiet enough in the afternoon,
Reserving their terpsichorean powers
To dance by the light of the Jellicle Moon.

Jellicles Part 4

World Atlas of Seagrasses by Edmund P. Green and Frederick T. Short - "a group of about sixty species of underwater marine flowering plants, grow in the shallow marine and estuary environments of all the world's continents except Antarctica. The primary food of animals such as manatees, dugongs, and green sea turtles, and critical habitat for thousands of other animal and plant species, seagrasses are also considered one of the most important shallow-marine ecosystems for humans, since they play an important role in fishery production. Though they are highly valuable ecologically and economically, many seagrass habitats around the world have been completely destroyed or are now in rapid decline. The World Atlas of Seagrasses is the first authoritative and comprehensive global synthesis of the distribution and status of this critical marine habitat. "

Over 300 accounts of the Flora of the British Isles have been published in Journal of Ecology.

Tommy Cooper statements:-

My friend drowned in a bowl of muesli. A strong  currant pulled him in. 

UKButterflies Larval Foodplants website page lists the larval foodplants used by British butterflies. The name of each foodplant links to a Google search. An indication of whether the foodplant is a primary or secondary food source is also given.

Please note that the Butterfly you see for only a short time has grown up on plants as an egg, caterpillar and chrysalis for up to 11 months, before becoming a butterfly. If the plants that they live on during that time are removed, or sprayed with herbicide, then you will not see the butterfly.
 

Plants used by the Butterflies follow the Plants used by the Egg, Caterpillar and Chrysalis as stated in
A Butterfly Book for the Pocket by Edmund Sandars.
Published by Oxford University Press London: Humphrey Milford in 1939.

THE LIFE AND DEATH OF A FLAILED CORNISH HEDGE
This details that life and death from July 1972 to 2019, with the following result for
UK wildflowers, birds, butterflies and moths:-

• "Of the original 186 flowering species (including sub-species), the 5 colour forms and the 8 unconfirmed species, (193 flowering species in total) only 55 have persisted throughout the 35 years of flailing since 1972. Of these 55 species:-
• 3 species are unchanged.
  11 species have disastrously increased.
  41 species are seriously reduced in number, most by over 90%. Of these, 18 are now increasing under the somewhat lighter flailing regime. 13 are still decreasing, and 35 have only a few specimens (from 1-12 plants) left.
• Of the rest of the original species:-
• 37 species and 3 colour forms have disappeared, then reappeared after varying lengths of time. Of these, 20 have fewer than 6 plants, most of them only 1 or 2, and are liable to disappear again. Only 6 of the recovered species look capable of surviving in the longer term.
• 23 species have reappeared, then disappeared again due to being flailed before they could set seed or to being overcome by rank weeds.
• Only 3 species have reappeared for a second time, and one of these has since disappeared for the third time.
  68 species and 2 colour forms disappeared and have never reappeared to date (2008).
• Of the 83 flowering species (excluding 11 rampant species) and 3 colour forms now present in the survey mile, around 50 are unlikely to survive there in the long term, certainly not in viable numbers, if flailing continues.
  Unless the degradation of habitat, high fertility and spread of ivy and other rampant weeds can be reversed, it appears highly unlikely that more than a dozen or so of the lost floral species can ever safely return or be re-introduced.
• The only birds sighted more than once so far this year along the mile have been magpie, rook, crow and buzzard, and a swallow (probably the same one each time) hunting between the hedges now and then at the sheltered eastern end of the mile. One wren heard June 21st, one blackbird seen June 27th (these also at the eastern end) and one greenfinch today July 31st. On this hot sunny high-summer day counted only 7 hedge brown butterflies (6 of them males), one red admiral and one large white. Half a dozen small bumblebees, two carder bees, half a dozen hoverflies of two common Eristalis species, one flesh fly, one scorpion fly and one dragonfly, Cordulegaster boltonii, not hunting, zooming straight down the road and disappearing into the distance.
• Only 8 butterfly species so far this year, and only one specimen each of five of them (red admiral, speckled wood, large white, ringlet and large skipper, the latter seen only once since 1976). Only small white, hedge brown and speckled wood have managed to appear every year since the flail arrived.
  For some years I have been noticing very small specimens particularly of hedge brown and speckled wood. This year nearly all the hedge browns seen in the mile ('all' being a dozen or so in total) are of this stunted size, some of the males appearing really tiny. I am wondering if this might be a response to general environmental stress, or due to inbreeding as flail-reduced numbers are so low. The hedge brown does not fly far from its hatching place so mating opportunity is now extremely limited. With the few species of insects now seen in the hedges there seems to be a high proportion of males to females, at least five to one.
• So far this year only a single moth has come to the house lights. It was a Drinker, and it killed itself against the bulb before it could be saved.

September 21st. Most of the survey mile closely flailed today along both sides of the road.

End note, June 2008. I hear spring vetch has been officially recorded somewhere in West Cornwall and confirmed as a presence in the county, so perhaps I can be permitted to have seen it pre-1972 in the survey mile. I wonder where they found it? It's gone from hedges where it used to be, along with other scarcities and so-called scarcities that used to flourish in so many hedges unrecorded, before the flail arrived. I have given careful thought to including mention of some of the plants and butterflies. So little seems to be known of the species resident in Cornish hedges pre-flail that I realise some references may invite scepticism. I am a sceptic myself, so sympathise with the reaction; but I have concluded that, with a view to re-establishing vulnerable species, it needs to be known that they can with the right management safely and perpetually thrive in ordinary Cornish hedges. In future this knowledge could solve the increasingly difficult question of sufficient and suitable sites for sustainable wild flower and butterfly conservation - as long as it is a future in which the hedge-flail does not figure.
Times and attitudes have changed since the days when the flail first appeared on the scene. The plight of our once-so-diverse wildlife is officially recognised as a priority; agricultural grants may embrace conservation measures, and perhaps economic strictures will tend more to a live-and-let-live policy in future with less of the expensive, pointless and desecrating "tidying-up". We now have an enthusiastic generation keen to help nature recover its diversity, but often unsure as to how this is best achieved. [Please see CHL "Restoring Biodiversity in Cornish Hedges"] 21st September 2007.
There is still widespread ignorance of the effects of such destructive machinery as the flail-mower and other rotary trimmers and strimmers. Few people but the elderly now remember or understand the life that ought to be abundant in the everyday hedges, verges, field margins and waste places. The simple remedy of returning to the clean-cutting finger-bar scythe used in late winter, trimming alternate sides of the hedge in different years, not trimming green herbaceous growth and leaving the cut material (mainly dead stems and twigs) on or near the hedge, is largely unrealised. This wildlife-friendly type of trimmer is still available from some suppliers.
Cornwall County Council has changed from being (in this instance) the chief offender to employing said-to-be environmentally-aware officers concerned with reconciling conservation and development. In recent years the council has issued instructional leaflets about hedges and their wildlife, including one entitled Cornish Roadside Hedge Management (since altered, perhaps not entirely for the better). This leaflet largely embodied the principles that our petition of 1985 asked for. Ironically, it is no longer the council's employees who are carrying out the work. Although this advice is now available, it does not necessarily reach the farmers and contractors out on the job. The flails are still in destructive action at any time from June onwards, though on the whole the work does seem to be being done later rather than sooner. Some farmers are now correctly leaving it until January and early February, a good time to allot to road work while other farm jobs may have to wait for drier weather. Most farmers, despite the bad publicity they tend to suffer, truly wish to do the best they can for their wildlife. Sadly for all, the flail is still the universally-available tool.
Those ignorant of the flail's real effects may imagine that 'sensitive' use of it is all right, as some common plant and insect species return temporarily and a few others increase when the work is switched to the less damaging time of year and done lightly. In the longer term, this is delusive; even in winter an unacceptable number of individuals are killed at every flailing and the habitat still inexorably degrades. No matter how or when or how seldom the flail is used, species continue to die out.
Until naturalists and environmentalists understand the catastrophic and cumulative effects of the flail they will continue to say they don't know why, despite all well-intentioned efforts, the numbers and diversity of wild flowers, songbirds, bats, butterflies, moths and bumblebees are still falling.
Nature lovers have to stop thinking mainly in terms of schemes to benefit a handful of charismatic species at special sites, and start looking at what the flail and other rotary mowers have done to thousands upon thousands of acres of the British countryside and billions upon billions of its most essential, ordinary inhabitants. It has struck at the major heart of the core existence of our native species, slaughtering them wholesale in that very sanctuary of the hedges and verges. These species had already mostly gone from the rest of the local area; the hedges where they had all taken refuge were their last resort. The remnants of species and their precarious survivors are still being wiped out, smashed to death every time the flail is used. It is the utterly wrong tool for the job and it has to be scrapped.
A brand-new flail-mower operating in February 2008. Right time of year for trimming, wrong kind of trimmer. As long as it is manufactured and turned out into the roads and fields the flail will decimate wild flowers, massacre the small creatures remaining in the hedges and verges, destroy their habitat and ruin the ancient structure of Cornwall's hedges.
Since the last yellowhammer flew across the road in 1980, I have never seen another while walking the survey mile. Since the last grasshopper in July 1981, I have never seen or heard another in these hedges. Since all the other species this diary recorded absent disappeared, they have not been seen again except in the few instances stated in the text. Most of the remaining species are declining. Fewer than half of them are likely to survive in the longer term if present trends continue. The long-vanished flowering species are likely never to return, as repeated flailing before seeding has exhausted their dormant seed stocks. The survey mile is typically representative of a majority of Cornish roadside hedges.
The photographs - in the pdf in their website - illustrating many of the flowering species lost were not taken in the survey hedge,for the obvious reason that they were no longer there. Most were taken in the house's wild garden adjoining, while those that did not grow there were obtained only with extreme difficulty, by searching all over West Penwith in a roughly thirty-mile radius for un-flailed pockets of survival. Along the roadside hedges, in this whole distance I found just one or two plants or patches of only a few of the species sought - common toadflax, field scabious, tufted vetch, scentless mayweed, red clover, self-heal - species that before the flail were so commonly seen along the whole length of hundreds of hedges in West Cornwall, now growing only where for some unusual reason of situation the flail had missed.
Some of the photographs of invertebrate species killed out by the flail in the survey mile were taken in the garden adjoining, where, despite nurturing since pre-flail days, the majority have now disappeared due to over-predation. In the survey mile this year, for the first time since 1992, the hedges remained un-flailed throughout the summer, giving a few common invertebrates the chance to reappear. No adult moth is illustrated because only half a dozen individuals were seen during the whole summer season of 2007, unfortunately at moments when the camera was not in my hand or they were fluttering out of reach. The drinker caterpillar alone was found posing beautifully and goes down to posterity as the only visible surviving moth larva noted in the survey mile this year, illustrating the millions of his kind killed by the flail.
Along this one typical mile of Cornish lane alone my records show that the flail has been the outright death or caused the persisting non-appearance of

• 90 flowering herbaceous species,
• 5 shrub species,
• 20 grass species,
• 60 moss species,
• 40 bird species,
• 23 butterfly species,
• 250 larger moth species,
• many scores of other invertebrate species, and untold thousands of individuals.
• It has condemned the hedge itself to a long-term, silent, living death, wrecked its antique stone construction and destroyed its great beauty. Along the whole of the estimated 30,000 miles of Cornish hedges the deaths of individual plants and creatures from flail-battering and the loss of their generations represent truly astronomical figures. The degradation of habitat resulting from flailing prevents revival in most species even where a few individuals manage to escape the physical impact of the flails. Although the effect in Cornwall with its solid hedge-banks and their more complex ecology may be worse than with the English hedgerow, the flail-induced wildlife crisis is nation-wide - and still almost universally unrecognised or unacknowledged.
• There is no hope of recovery for our countryside wildlife until the flail type of machine is consigned to the black museum of history. To achieve this it will probably have to be banned by law.
• The finger-bar scythe has to be reinstated and any trimming (except where needed for road-junction or access visibility) must be carried out in winter, the later the better between November 1st and February 28th. Trimming must take away the woody scrub growth on the sides of the hedge, leaving the herbaceous growth on the sides and the bushes on the top untouched. Only then can the flail-ruined hedges and verges begin to see a real return to some kind of healthy and abundant life."
