A familiar feature of many field corners, village greens and gardens, ponds are generally small in size. Unlike lakes, ponds are relatively shallow (being no more than 180 cm deep). The water in a pond is still. It does not flow like in a river or stream. Natural ponds are not connected to each other or to other water bodies and are only filled up by rainwater or groundwater.
In this fascinating clip, we learn that ponds are the perfect habitat for many plants and animals. Building a pond is a great way to attract wildlife into a garden. Some creatures will stay in a pond their whole life, while others will just visit to reproduce or feed. How would you build the ‘perfect’ pond? Watch the clip to find out.
