Ponds
for wildlife
Almost any water body, whatever
its size, will have some wildlife value, even if only as a drinking
place. This value can, however, be greatly increased if the pond
is well designed and maintained. This leaflet describes how to make
and look after small wildlife ponds.
Planning a pond
You must decide what wildlife
you want to attract before you dig your pond because its position,
size and shape will affect its appeal to different species. There
is a lot of information available on the creation and maintenance
of ponds. Much of it is conflicting, in part because no-one knows
all the answers and also because different types of ponds are made
to attract different wildlife. First, you have to be sure what you
want from your pond. A relatively small garden or school pond, for
interest and pleasure, as a place where birds can drink, children
can be shown wildlife; or a more ornamental pond for fish.
In general, for wildlife, the larger the pond the better, provided
there is a wide variety of habitats.
Garden ponds
Most garden ponds are very
small, but they can still provide homes for wildlife. Mostly, this
will be of common, mobile and adaptable species, but none the less
interesting for that. Garden ponds can be important for frogs (they
became very important in the 1960s when frogs suffered a serious
decline). Dragonflies may breed in ponds, and a surprising number
of birds may drink and bathe in them. Such ponds can give enormous
pleasure, and give children and many adults their first real experience
of wildlife.
Where to site a pond
Warm, sunny sites are probably
best for wildlife, so try to make sure your pond has an open aspect
to the south side. Trees can be a problem: if your pond is sited
under mature trees, it may fill with autumn leaves, but if it is
under young trees you may have problems with roots puncturing the
pond lining. Low bushes near a pond can provide cover for bathing
birds, but remember that they can also harbour cats. For better
birdwatching, build your garden pond so that you can see it from
a window.
Do not automatically place your pond in a wet or damp hollow. These
areas may already be important for wildlife. Indeed, having more
than one wet area in a garden can be very good.
Pond shape
A pond should have gently
sloping sides to give the all important shallow areas on which much
wildlife depends. Birds will drink and bathe in the shallows, and
they are important for spawning amphibians. Sloping sides are also
important for safety, both for children and to allow wildlife such
as hedgehogs to escape. In general, the more varied the slopes and
the longer the shoreline, the better.
Although the shallow areas are important for insects and spawning
frogs, ponds should also have some water over 60 cm deep, so that
they do not freeze solid in hard winters.
