Wether its hunting for conkers, kicking through drifts of leaves or witnessing stunning sunsets, Autumn is a magical time of year to experience woodlands.
As the days start to shorten and the once green leaves take on fiery shades, wildlife is making the most of the last warm days - with birds and mammals in search of fruits and nuts before winter makes an appearance.
Beech trees put on a particularly spectacular autumn display. Find beech woodlands on sites such as Deepdean Terrace.

Why do leaves change colour in autumn?
Shorter days and cooler nights trigger seismic changes in leaves during autumn, creating spectacular seasonal displays. As the days become shorter, the production of green chlorophyll begins to stop. Existing chlorophyll breaks down and the green colour fades. Yellow and orange 'carotenes' that you can’t normally see become visible, making the leaf change colour.
A layer of cork-like cells also form across the base of leaf stalks. Sugars then become trapped and concentrated in the leaves and are converted to 'anthocyanins', making them appear red, purple or pink.
Weather conditions can also have an effect on leaf colour. Sunny dry days and cold (but not freezing) nights create the best autumn colours.
why do conker tree leaves go brown first?
Come late summer, horse chestnut trees can look quite sorry for themselves. This has nothing to do with the changing of the seasons, but is actually down to a leaf-eating insect.
The horse chestnut leaf-mining moth was first identified in Wimbledon in 2002 and has since spread rapidly across England. The moth larva feed inside the leaves, causing brown or white blotch mines to develop between the leaf veins. Heavily infested trees will drop their leaves early.
Although it looks unattractive, research has show that the insects have almost no effect on the growth rate or health of the trees.
Conker or chestnut?
While horse chestnuts (conkers) and sweet chestnuts might look similar (both have a green spiky shell and a brown nut), they are in fact very different. Whilst sweet chestnuts are delicious when roasted, bitter conkers contain aescin and are mildly poisonous, so you don't want to eat them.
How to tell horse chestnuts and sweet chestnuts appart
Sweet chestnuts are often found two or more to a shell, which has many extremely sharp long densely clustered burrs. Conkers are rarely found more than two to a shell, which can have widely spaced short spikes or be completely smooth.
Sweet chestnut trees have single toothed leaves, whereas horse chestnuts have a compound leaf with 6 or 7 leaflets. Sweet chestnuts also have multiple spikes of yellowish white flowers in spring, whilst conker trees have single upright spikes of attractive blooms.
