You don't need a lot of space to put in a pond. Preformed ponds are available in sizes as small as a metre wide, and are quick and easy to install.
Of course if you do have space to spare, the bigger the pond, the more wildlife will be attracted – and a large wildlife pond could provide a stunning feature in a big garden.
With the construction of any wildlife pond, there are a few important points to be aware of. Firstly, it's essential to have areas of shallow water at the edges of the pond. If the pond's sides are too steep, visiting wildlife will struggle to get out –hedgehogs and other small mammals may even drown.
Putting in some native plants, such as starwort or water crowfoot, will oxygenate the water, keeping it naturally clear and clean. Some non-native plant species are highly invasive, so these should be avoided.
And ponds are very attractive to young children, especially when the water is teeming with fascinating creatures. Pond dipping is a fun and educational activity, but children should always be carefully supervised near water, even if the pond is shallow.
All new ponds, big or small, will begin attracting wildlife almost immediately. And after just a few months, you could have your own little army of slug-munching frogs and toads helping out on your plot.
