Most plants change with the seasons. When there is
plenty of sun and rain they grow rapidly by putting out new shoots and
leaves. As the weather turns cold or dry, plants often look as if they
have stopped growing altogether. Wildlife know when winter is approaching.
Their behaviour occurs in response to the reduction in the amount of sunlight
during the day. In the UK, the length of the day decreases in summer and
autumn every year as a result of the Earths' movement around the sun.
Animals respond to this; for example heathland birds such as the tree
pipit and nightjar will migrate to spend the winter in Africa. Plants
also respond to the shorter days. Leaf shedding in deciduous trees is
a means of conserving water duri
ng the winter months.
Sunny mornings in spring and early summer are an excellent time to look
for basking snakes and lizards: the adder is a snake commonly found on
several of the Coversands heathlands, as is the common lizard. Look for
a sheltered, south-facing slope on warm early spring days. Heathland birds
include whitethroat, tree pipit, stonechat and woodlark; all may be seen
perched on top of heather or gorse, and sing during spring and early summer.
Summer evenings are a good time to watch hobbies catching dragonflies;
or listen out for the churring of the nightjar. In boggy areas, search
for sundew - a carnivorous plant which increases its nutrient uptake by
catching insects. Autumn & winter can be quiet on heathland, but some
birds may be more visible due to the lack of cover. Look out for the great
grey shrike which is a rare visitor from Scandinavia, and the colourful
green woodpecker.
What is the weather like today? Is it cold or warm, is it raining or is
it sunny? What do the clouds look like, is it early or late in the day,
what colours can you see in the sky? Is the wind strong? Which way is
the wind coming from? Look for clues to help you find out. What can you
see that will help you? What season is it? Do you think this affects what
plants you will find? Look at the site, are there plants on the ground
or is it bare? Are there many birds or other animals around? What are
they? What is the temperature? You will have to use a thermometer to tell
you how warm or cold it is. If you hold it in the air for several minutes
and then read the number at the top of the line this will tell you what
temperature it is.
