Dear Supporter, 
This summer might not have been the barbeque one forecast by meteorologists - but this autumn looks set to be a sizzler in terms of autumn leaf colour.
So why do we sometimes have fantastic displays of reds, golds and yellows while other years seem to pale into insignificance? It's all linked to the weather and the way many kinds of trees shut down their food production at the end of the year. You can read a full explanation of how it works on our website, but if we have sunny dry autumn days with cold, but not freezing, nights then a riot of colour will be on the cards.
You can help us track the changes in the seasons and see the effect the changing climate is having by visiting our Nature's Calendar website. Our volunteers play a key role in helping to track changes in our climate and more volunteers are always needed.
Autumn is a great time of year for getting out and visiting a wood - from collecting conkers and kicking leaves, to just enjoying the seasonal spectacle that is autumn colours - there is plenty of fun to be had!
Happy autumn.
