#Evolvetheforest 2019

To say that the Evolve the Forest conference was a success would be an understatement.  The conference, organised by the Royal Forestry Society, ArtdotEarth and Timber Strategies and hosted by Dartington Hall, managed to do something that not even the organisers were sure they could pull off as they brought two seemly opposing worlds together: commercial forestry and art.

At first it seems like an odd combination but there was a common thread, namely our relationships to trees and woodlands and the threat that they currently seem to be under.

From a forestry perspective a tree is a crop.  It is grown in large quantities and harvested for economic and resource based reasons.  We all rely on wood and wood based products in our homes and going forward we may rely on them even more as we reduce our plastic usage and find other ways to create energy through biomass.  The seemly chaotic climate along with the increased threats from pests and diseases are a serious issue to this industry and organisations such as Forestry England are thinking hard about alternative trees and ways to grow them that will cope in an uncertain future.

The artistic perspective brought in the emotional aspect of our relationships with trees and woodlands.  It’s undeniable that we have been enamoured with trees for a very long time.  They are present in our myths and our stories and hold a special place in the hearts of many cultures.

It is this emotional response to trees that can be helpful, and sometimes unhelpful.  My own perspective has changed dramatically since I became a coppice worker.  Before, as a city dweller, I’d bristle at the thought of any tree being cut down.  But now I understand that a woodland is a living entity, and the individual tree is a part of that entity along with thousands of other lifeforms.  Even so, respect is due to the individual tree and allowing a certain amount of emotion and reverence for the life of that tree influences the decisions that are made about it.

The question of the conference seemed to be; how do we bring both of these perspectives together to create a culture of respect when managing woodlands and harvesting timber?  To encourage Each of the delegates were invited to step outside of their comfort zones and go to a lecture they may not be familiar with and that represented the ‘other side’.  There was a delightful moment when a grey haired gentlemen working for Forestry England gushed at how much he had enjoyed a particular lecture and that it wasn’t something he’d usually engage with.  Later on I saw the same gentleman enjoying a performance piece by Tom Marshman – We Need to Talk About Bambi, and I over heard him afterwards reflecting emotionally on the deer that he’d had to cull, a necessary but clearly not heartless act.  In another conversation an artist lamented over the need to kill deer at all and the forest manager student next to her explained why it was necessary to protect our woodlands from over browsing.

These were the moments that made this a very special and unique event, an event that will hopefully be repeated again in the future and perhaps include a speaker on the benefits of supporting coppice workers and the woodlands they manage.

Playing with Fire

It’s almost summer so it must be time for charcoal making!  This week I was at Westonbirt Aboretum where Brian Williamson has been restoring their coppice and making, among many other things, charcoal.

Copper grease is used on the bolts as normal grease would burn away at high temperatures.

Charcoal making has this air of romance.  I don’t know if its the plumes of smoke – that is actually mostly moisture – the site of people covered in black dust or the anticipation and skill in actually cooking the wood and not burning it all… or leaving it half baked, but it harks back to something earthy and oldy worldy.

In those olden days people would use earth mounds to cook their wood and this can still be seen at events such as Char Fest, which is hopefully being held again this year for new enthusisasts such as myself.  Up until recently the ring kiln was the charcoal makers tool of choice.  This involved lighting a fire inside the kiln and adjusting chimneys and vents to control the air flow and temperature.  It also involved climbing in the kiln to shovel out the charcoal… which, I am told, is a very messy job indeed!

These days we have a marvellous instrument called a retort.  Not only does it have an almost 100% converstion rate, (we only had two or three ‘brown ends’ – the name of undercooked wood – out of the entire burn) it also resuses the gases expelled by the wood as it cooks.  A fire is needed to start the whole thing off but when it reaches 420 celcius the retort will use the methane gas from the cooking wood and it becomes self-perpetuating until the gas has been used up.  And you don’t have to climb in the thing to get all the charcoal out.

I didn’t get a chance to try out the ring kiln but I did see how a retort, an oil drum and even a tin can will turn wood into charcoal and I’m looking forward to practicing the latter two when I get home.


“Why use charcoal?” I asked, hoping I wasn’t about to shoot myself in the business foot.  But Brian gave some good answers… charcoal burns at a hotter temperature, turns into embers quickly and has no smoke.  The charcoal that is made by local woodland and coppice workers also has the added benefit of being additive free, has reduced transport miles and of course it supports us woodland folk to support our woodlands.  Sounds good to me!
