Woodlands, Wildness & Red Squirrels
One thing that has been ever evident through the years has been the direct correlation between disintegration through rot and the power of wind, water and I am sure, other elements beyond our knowledge. Wind and water work together to first enter the tree at the point where divided stems fill with water and wind driven particles that compost in that crotch. A weak point develops and slowly rots into the wood inside. Beetles and worms do their work too. here you can see the initial rot in fully rotted entry. Following that came the newer area as the rots [permeates the fibres. Insects enter freely now and so too the bacteria and other parasitic workers. This is where good management can intercede in localized forestry and woodland management. If the rot is discovered early enough, limbs can be removed and the stem bolstered by limbing and sealing.
Notice at the top of the remaining stem where the rot had started and weakness gradually established its hold…
…and then here on the start of one of the forks where the weakness was. Good wood nearer to the lens and gradient levels of rot up toward the farthest point5 feet further on
I like the concept of seeing into unsawn wood because I see better the internal structure in its many diverse and complex layers. It is impossible to peel the tree and the many years of growth; say like an onion.
As the wood lies like a sprawling corpse I met a friend, Craig, who catches the grey squirrels, removes them from the region and has worked for fifteen years to reestablish the indigenous red squirrels that were ousted by the introduced American greys.
Today we have no reds in the National Trust woodlands at Penrhyn Castle, but soon we will see them return as they cross the two bridges from the Island of Anglesey where Craig and his supporters have worked so hard to help the red squirrels reestablish them with viable new life. No greys are on the Island now. You can read more about the work on their website and follow the progress as we go here.
Paul, I’ve taken a look at that book in my lunch hour and you’re right; it’s a fascinating read. It’s gone straight into my wish list (I’m busy buying timber for my workbench at the moment so funds are tight). My family and I were recently in Denham country park – a chance to blow away the cobwebs and take in the quiet. There were several trees that had come down in the recent storms and I spent some time with my children looking into the past with them as we examined the insides of the split trunks and branches. I don’t know about you, but I’m always torn between feeling a bit sad that such beautiful things have been pulled down and cheered by the promise that the saplings nearby will now have a chance for growth. This feeling then spills over into my workshop life as I remember that the wood I’m working with was once a living thing and it deserves the best that I can do rather than ‘that’ll do’. Sometimes, I take that too far though as I try to make every scrap of wood count and end up locking myself into a paralysis of indecision but that’s something I’m working on. Happy times Paul – hopefully you’ll be seeing some Reds in the woods where you are before too long.
With dedicated people like Craig in the loop I am sure I will see them.
Here in Eastern North America acid rain compounds have had terrible effects on hardwood growth. Whilst some varieties seem to persist into old age many younger trees of the same species will now snap somewhere up around the middle section when their diameters reach 6 to 12″ even during moderate winds. This was not something I witnessed as a younger person who hiked extensively in New England forests. Many young trees now seem to die even before they are 3′ in diameter.
Even a lay person seeing this sort of damage knows there is probably something happening to the cell structures of these trees that surely must be causing this brittleness. The Ginko tree was planted along many city streets here years ago because it seemed to survive auto fumes better than many of our own hardwoods. It survived the dinosaur extinction and probably will outlive our own. I have cut and used many trees in my lifetime but I continue to plant as I attempt to replace more than I take. I am not familiar with Bruce Hoadley’s work but thank you Paul for pointing it out.
just the book i have been looking for .i am surrounded by my national park here in killarney Ireland and would often not be able to identify one tree from another although i do know its one of the oldest natural oak woodlands in europe and i have a grasp of biology this is an ideal read to understand the true nature of what i am actually looking at .thank you
