Not only are there quite a few brown leaves, but the terrible wind and rain on Monday have brought down quite a lot of green leaves as well as a few smaller twigs. There’s clearly only one way this is going.
In the meantime the canopy still looks very full
Although close inspection shows a lot of browning
I was investigating the whole deciduous cycle of trees and came across another new word for me – Abscission, a noun meaning
As far as trees are concerned, they first withdraw valuable pigments, like chlorophyll, from the leaf, (hence the loss of ‘green’) and then form a thin band of dead cells at the base of the stem, separating the leaf from the stalk. The leaf tissue then dies and drops to the forest floor where it decomposes, any useful nutrients can then be reabsorbed through the roots.
One of the other words I’ve learnt by taking part in this meme, was ‘Mast’, and looking online I found an update in the Guardian about whether this is a Mast year. http://www.theguardian.com/environment/2014/sep/25/acorns-in-short-supply-say-forestry-commission-and-naturalists
And the answer, as I thought in my August post is no. Whilst 2013 was a mast year, 2014 definitely isn’t. Think I’d better stock up on some hazelnuts for the red squirrels.
