More Green Engineering



By C:

It is nice to know that one is appreciated.  This was what the local bird population made of our labours last week:


Since then, temperatures overnight have fallen considerably.  We have still not had any serious cold yet this year: negative Celsius readings yes, but not in double figures.  Nevertheless, first thing today, the air was cold and crisp.  “Like vodka”, as a character in a Russian novel was wont to say.  The character: possibly Viktor’s mother, in Life and Fate.  Or maybe not.  It’s an awful lot of pages to read to double-check!  The first hard frost of the season here anyway: 
Outside temperature at dawn: minus 4.3 C
Some plants which have been hanging on with Green-Gym tenacity ...
may have to admit the growing season is over?

The airflow over Britain has been from Scandinavia, veering from Russia, but the sun had warmed things up before session-start.  The site to which we had been summoned this week, looks mighty fine at first light.  These shots were taken earlier this month:
River Thames and the spire of St Peter's Church Wallingford

Wallingford Bridge.  In the background: remains of Wallingford Castle


Given its location – between the town of Wallingford and the increasingly urbanised village of Crowmarsh – I think Riverside Meadow would count as the kind of “urban nature” for which NDD-campaigners contend.  NDD: Nature Deficit Disorder (not a real medical condition – just a term used to describe post-industrial-age alienation from the natural environment.) 

To counteract NDD, there is nothing like working outdoors on a nature-conservation task.  One of our volunteers reflected how lovely it is just to be out and about in that beautiful surroundings, then added, “Actually it’s a good thing to be doing something!”  To which the inevitable reply was: “Well that is rather the point of Green Gym!” 

Shortly after, came one of those wonderfully surreal passages of Green-Gym conversation, among a group of members of pensionable years, on the question of which one of them was going to climb back over the barbed-wire fence to fetch an extra tool:
“… You stay there: it’s easier for me, on account of my junior age.”
– “And you’re taller.”
– “And you speak French.”
That led in turn to musings on what ‘Green Gym’ would be in French.  [Answer is: La Gym au Vert. – Ed.]   

Meanwhile, today’s task was more ‘green engineering’.  ‘More’ in the sense of further engineering works to complete a project, rather than adapting materials or methods to make the works carried out yet more eco-friendly.  We were aiming to complete a job started last month (25 October): installing/topping up the willow bundles on the larger of the two sections of bank which have in the past suffered from erosion.  

First, there was a trailer to unload:

This proved a little tricky, as the detachable sides proved reluctant to allow themselves to be detached.  Then the materials, which had settled during the ride, were reluctant to allow themselves to be taken off the trailer.

Bundles which had come undone in the year since they were fashioned, were re-tied.  And all were carried for the last leg of their journey, the short distance to that stretch of the river-bank under reconstruction.  At least one was greeted with a snatch of song:
“There’s a bundle coming in!”

There the willow-packs were laid parallel to what will be the new shore-line in due course:


Other Green-Gymmers raked up the remains of the tall-herb vegetation which had been given its cyclical cut:

The cuttings were spread over the willow-bundles in situ, to deter those members of the public who think the wood has been gathered and piled up specially for them to use as firewood for their bank-side BBQ parties.

All this activity stoked up an enthusiastic response to the magic words “Tea break!”  For weeks, one of our volunteers has been giving away apples by the boxful.  This week, he had recycled some of the surplus fruit from the apple tree in his garden:
Apple cake made according to the recipe in the WGG Cake Book (for which we cannot post a link – sorry! – because the book, which we wrote and self-published, is sold out)
By session end, the task had duly been completed.  And not only were we warm from the exercise, but as the last stakes were being hammered in to secure the bundles from floating away next time the river rises, the mercury had risen to 4.3 Celsius:

Mud Dogs and Englishmen



By the Session Leader:

Miserable day.  Raining.  Forecast not good.  We are supposed to work here:
The temptation is to spend the morning here instead:
But no: Green Gymmers work whatever the weather: mid-day sun or mid-day rain.  Besides, the rain has stopped, and the pub isn’t open yet ... 

So what was the task?  Water-channel clearing, again!  “I thought we did that last time 
we were here!” called out one volunteer.  – “Yes,” came the relentless reply from the site warden: “but that was last month.  The cress has had four weeks to grow since then …” 

He was teasing, of course.  Cress does grow year-round.  (Indeed it was planted to be a winter crop for local people: when frost threatened, they would submerge the plants beneath the stream, where the water remains at a constant 11 Celsius throughout the year.)  We, however, were set to work at a slightly different spot from last time, upstream.  

A squad of apprentices from RAF Halton had made an excellent start on this sector the previous week, but channels needed to be made still wider, growth on/by the banks cut back, and further progress made upstream, even to the education centre if that was possible …  So everyone to work!

As it was not feasible to deploy wheelbarrows in this zone, the team split into three.  The ‘cutters’ cut back the cress, and piled it onto the bunds to drain off some of the water:


The ‘porters’ then carried it by the forkful, or dragged it with the muck rake, over to the bank.  Some care had to be taken not to sink or trip in the mud, which had accumulated in the middle areas:


Floating cut vegetation along the stream with a muck rake was easier for the porter, but naturally meant that the cress was waterlogged again by the time it came to be loaded on to the bank.

The ‘stackers then piled it into neat rows at the back of the bank (but away from the fence, so that the neighbouring landowner’s fence-posts do not rot prematurely), leaving a path at the front:


By tea-break we had worked our way up to the dam across the stream:

Today’s cake from our star baker was so good that the sole photographer today [aka the Session Leader – Ed.] was too busy eating to remember to take a photo of the goodies!

In the second half of the session, progress on the bank was slowed down by some heavily overgrown ‘undergrowth’:

Even so, by session end there were some impressive mounds of cress (and mud) piled up along the bank:
The photograph does not convey the smell, which was particularly pungent at this end.  “Like rotting seaweed” according to one Green-Gymmer; described more positively by another as “reminiscent of summer childhood holidays.”  To get an idea of the scale of 
the operation, mentally multiply the pictured vegetation by a factor of 3 or 4.

We did not reach the education centre, but the site warden ‘promised’ us that we could continue up to there next time.
