Dodging raindrops


When clearing watercress channels, the only wet should be: the stream in which volunteers are wading; the moisture content of the vegetation being removed; and the sweat patches on our T-shirts (waterlogged plant-life ain’t alf eavy).

The weather could have been more unmannerly.  At dawn, the situation could most politely be described as “steady downpour” with a 90% chance of “heavy rain” mid-morning.   Precipitation, however, put itself on hold for session-start and end, and managed to keep itself tolerably in check in between.  (Was that the odd rumble of thunder we heard in the distance?)  And ducks are famously fond of the rain anyway:




The camera was not so enamoured of the atmospheric conditions when the moisture level rose:


Once more, the tasks for the humans on site – besides taking photographs – were to keep the water-channels open.  By cutting or pulling out excess plant growth.  Again.  Piling risings on to bank or bund, for water to drain off and invertebrates to make their getaway.  Again.  Wheelbarrowing cuttings to compost heap.  Again.  [I repeat myself when under stress.  I repeat myself when under stress.  I repeat myself when under stress.  I repeat myself when under stress.  I repeat –   Ed.]

The taskforce split into two, to work respectively up- and downstream from the road bridge.  Upstream, an enthusiastic group of volunteers from another organization had already shifted piles of cress on to all along the bank.  Welcome to our newest volunteer! who was getting stuck in straight away under the eye of one of the old and bold.



Downstream, Green-Gymmers were more spread out, and a tad more demonstrative about taking pride in their work.  One paused for a photo-call:


“I did!”

Upstream, cress was piled straight onto the bank.  Downstream, a team effort was required to barrow it across the beds, and transfer it to our waiting expat …
 

who in due course carted it away to the compost heap:



Further downstream yet, another volunteer was able to use the muck rack to drag floating cutting on to the bank – an admirable demonstration of technique and ingenuity:



The exertion plus humid weather worked up quite a thirst and appetite for cake – and conversation:


“I like it!”

Bravehearts


By ‘C’:

‘Why couldn’t it have been Green Gym yesterday?’ is a common enough lament from a session photographer. 

Somehow the light is always better the day before, or will be tomorrow.  Yesterday, a lingering mist may have disappointed some bank-holiday-weekenders.  For shutterbugs, however, the unusual light-conditions leant an eerie beauty to the Chilterns landscape:

(Dampness also meaning one could be walk all morning and meet with any number of rabbits and skylarks – both species supposedly in decline in Britain: evidently not in rural South Oxfordshire – but as for humans … Well I saw just three cyclists, two hikers, and one dog-walker; oh, and a wingwalker.)

The mist did, eventually, clear.  After warm sunshine in the afternoon, topped by a glorious sunset, it seemed reasonable to hope that conditions would be good today as well.  But no!  Good for doing Green Gym; not brilliant for recording it for posterity …

The site warden had told us he had “a range of interesting, challenging tasks which members of your team would not want to miss.”  If there was an element of gently irony in that statement, there was nevertheless a spread of tasks for volunteers to choose from, as we gathered on the banks of a characteristic Chilterns chalk stream.

If it had been a bright summer’s day, it would have been an idyllic scene.  You can let your imagination play with these images?





Even on a grey day, it was really rather a lovely place to be.  Especially as we were lucky enough today to have an acoustic backdrop of gentle birdsong, but almost nothing else bar the sound of the wind in the wild grasses, and the patter of the odd cute bunny scampering out of the way.  And it could have been quite challenging: witness, the surprise amber rain warning posted by the Met Office this morning.  Fortunately, Green-Gym fell into the category of the 30% of occasions when the prevailing conditions did not result in a downpour.


One option for volunteers today was to do some raking: to remove cut material from “patches” in the wildflower meadow, and transport it to the compost area.  The patches had been generated by an exercise to try to knock back the Meadowsweet (Filipendula ulmaria).  As the name suggests, it is a sweet-smelling flower; and does very well by the neat trick of producing a heady fragrance (which for many people is the scent of summer in the wild), but no nectar: the insects keep visiting it regardless.  Unfortunately, at this location it has been doing rather too well, and threatening to monopolise the meadow.

Two Green-Gymmers promptly peeled off to set about raking.  Then returned about 30 seconds later, remarking a little sheepishly, “We might need rakes.”  A sentiment with which their colleagues readily agreed!

Once fully equipped, the rakers did rather a good job:


Task 2, which absorbed most of the manpower available, was to weed a section of the stream which is supposed to be devoted to watercress:


Looking at that photograph, you may wonder what the curious object is, which can be made out in the background (top edge, in the middle).  It is in fact what I would call a ‘bug hotel’.  Only this one is more superior, and is billed as an ‘Insect Palace’:


The weeding is still done by hand, as it was in the days when this was a working watercress-bed:


The weeds are then moved – like the cut materials from the wildflower meadow – by muscle-power and wheelbarrow to compost heap:



And the definition of ‘weed’ in this context?  It was not as simple as ‘any plant which is not watercress’.  For the beds being worked on are substantially colonised by Crowfoot (Ranunculus aquatilis), aka White Water-Buttercup.  Which would normally be quite desirable in a stretch of Chilterns chalk-stream, just not in a zone right outside a Watercress Beds Visitor Centre!  OTOH, it is difficult to eradicate, and Green-Gymmers’ time and effort were better directed towards other species.

Which species, precisely, was a question which came up throughout the morning.  This specimen, for example, which one Green-Gymmer carried round the site looking for someone to identify it, and decide its fate:

It was with a friendly smile (or it would have been impossibly rude) that, inevitably, at least one Green-Gym colleague called out, “Are you sure that’s not too heavy a load for you?”

Not that I personally was of much more assistance.  All I could say was that it was a water-plant, but not watercress.  For if some of my fellow Green-Gymmers will cheerfully admit to being “botanically challenged”, they have nothing on me, who sometimes has difficulty telling animal from vegetable from mineral.  Yesterday, for example, I had no idea that this slimy blob on top of a poppy flower was not some creature which was going to bite or sting me if I examined any closer:

It was, almost certainly, just the outer covering of the flower which, in poppies, (usually) falls away as the flower opens.  Which just goes to show that this Green-Gymmer can be about as smart as a stick.  [Well you said it – Ed.]

As for the mystery plant in the stream, that was assigned to the category ‘weed’: “probably Mimulus [guttatus] – Monkeyflower.  It’s a garden escape.  Pretty, but a real pain.”  According to the NNSS (Non-Native Species Secretariat, a Defra agency), it is “very stoloniferous and so tends to form extensive stands in suitable conditions.”  In its native western USA, Canada, and Alaska, it is in the wild limited to eking out a living in marshy areas and high-altitude meadows.  In Europe, it grows rampantly beside river, rill, or stream, alongside ditches, on wet pastureland, in disturbed ground, etc.

Meanwhile, as the morning advanced, the third team was progressively reinforced until it became a regular chain-gang.  The gang was engaged on what had been billed as the mystery task of the day.  “Path levelling” the site warden had said: “major earth moving job – not for the fainthearted.”

He was not kidding.  I had not supposed that he meant this kind of ‘not for the fainthearted’:

And we know I can be as bright as Alaska in December.  Even so, I do not think I was the only one at Green Gym who had not envisaged the immensity of the operation.  It really was to remove an entire embankment – just like building a railway.  Unfortunately, impossible to convey the sense of scale by photographic image!

First item, vegetation removal:


(On the left, behind the brash heap, you may be able to make out one of the rakers on the wildflower meadow.)

Then earth-shifting:


Followed by … a break.  Being a navvy made even the strongest Green-Gymmers need to pause and take a breather, while being briefed on the bigger picture of the project:


The line of the new path was surveyed:


Then back to the hard toil:

– For those who were still stout-hearted, that is.  As for me, I don’t mind admitting that half a dozen spells on that were as much as I could manage. 

It was at that point I swapped mattock & shovel for camera again.  There was, after all, some vital photo-reportage to bring to a conclusion: to show how much was achieved over the course of the morning.  Results from raking are more easily seen by the naked eye than through the lens of a camera – sorry!  The effectiveness of navvying and weeding, though, yes that I could document:
