Shy Oaks

Example of Crown Shyness in Oaks
Crown Shyness

Well lovelies, it’s been rather some time since we last got together on the blog, how the devil are you all?

Like a good swathe of the country we have been enjoying a splendid snowfall. I say enjoying, I know it makes travel, work and school difficult, but from an aesthetic point of view it has brightened a dark and gloomy run up to Solstice. I still have a child like delight when it comes to snow and this year, unlike others, it came on a Sunday which was most considerate. No panic about the commute or how to get the children to, or from school, and, as I can work from home (plus said children are now at Uni) even a snowy Monday could be enjoyed rather than endured.

Originally I had thought this post would be wordless in a Wednesday kind of way, however when I was looking through the numerous pictures I’d taken over the last few days this one perhaps deserved a little explanation.

On the one hand, it’s just a group of oak trees, lightly dusted with snow against an almost azure blue sky, clinging precariously to the ridge of a hill. Nothing much needed by way of an explanation there, on the other, it’s an example of Crown Shyness*. Not the finest example you’ll ever see (to actually get directly beneath them I would have had to be a mountain goat with crampons) but an example none the less.

When we talk about Crown Shyness, it has absolutely nothing to do with a suited and booted actresses meeting her future in laws for the first time, but, a phenomenon occurring when tree crowns avoid touching or overlapping their neighbours.

Nobody seems to know why it happens, although there have been various theories in the last 100 years, from self pruning where branches rub together, the effects of differing light levels within the canopy and evolved self preservation to prevent the spread of parasites and diseases travelling from crown to crown. The only things I concluded from looking at this particular group of Oaks is that they seemed to be the same age, rather beautiful and probably just do what they do with no regard to the inquiring minds of humans.
