There’s a lot to do in the NPTC assessments. They have to learn to read the forces in wood to stop their saws getting stuck, they need to be able to use the saws accurately and safely, and they have to know how it works, and how to maintain it inside out.
L-R Kane, Jack, James and Finlay, who all worked very hard from hitting the ground running on Monday morning to taking their ROLO written tests on Friday afternoon…. Well Done!!
FOCUS on...tree ‘sleep’.
In addition though, recent research has highlighted something a bit different, that is going on in birch trees:
This article, and I would suggest you have a look at it, is from last year. It is very interesting, and the research is ongoing. Scientists used laser scanners to look at the shape of trees during the day, and at night. What they found was fascinating, trees appear to relax at night, and their branches droop. It could simply be that water pressure in trees changes at night, but it could also be that trees are actually deliberately resting because they don’t need to use the energy they would normally use to hold their branches at the correct angle to the light, which is very energy intensive.
The research is now focussing on which of these scenarios is accurate.
Do trees sleep? - watch this space!!!
