Chlorophyll is the green pigment primarily responsible for photosynthesis. The grass on the path, the conifers and some of the lower hazel (Corylus avellana) leaves on the bottom right, are clearly still green in colour. Chlorophyll usually masks the other colours, making plants look green but other pigments are present throughout the year, but only show up once the chlorophyll is being broken down.
Once the chlorophyll is less dominating, Xanthophyll starts to show, which is primarily a yellow colour. The hazel bottom left is a glorious butter yellow colour.
In the background is a type of southern beech, the Raoul (Nothofagus procera). It is not a native tree, but has been planted in some forestry areas, because in its native South America, it is an important timber tree. This goes a spectacular crimson caused primarily by carotinoids- yes you guessed it, the pigment that makes carrots orange. It is also present throughout the year, but masked by the green of chlorophyll.
As the chlorophyll is broken down, the tree starts to produce anthocyanins. These are not present all year, but are synthesised as the leaves break down their green pigment. These contribute to the dark reds such as the purple colour of the beech (Fagus sylvatica) to the right of the Raoul.
Once combined across an entire woodland you get:

There was an article in the Guardian online
It appears that the supermarket chain Iceland, and Greenpeace the environmental group, had got together to produce a Christmas advertising campaign highlighting the destruction of forests for palm oil plantations, and the ongoing slaughter of orangutans and the loss of their habitat. Some might applaud this as a change from the norm, but unfortunately it appears that this advert has fallen foul of an advertising watchdog, and been banned for being overtly political.
Apparently saving forests, or our now critically endangered relation, is considered to be in breach of the Broadcast Code for Advertising Practice (BCAP), and so we will be denied the chance to see the advert on television, or get the chance to raise awareness and educate those who could make a difference, by choosing the products they buy.
I suggest that you take a look and make your own mind up
This lovely bracket fungus, is mainly found on oaks. It has a very shiny almost plastic like surface, and brown cocoa powder-like spores. It seems to cause removal of the lignin from the tree, which reduces the wood almost to a paste, which can cause the stem or roots to fail. This tree had been reduced to a stem, as it was adjacent to a kid’s playground!!
