Book 30, Question 15
How does a backyard pond fill up with life?
A backyard pond starts as a hole with a waterproof liner, filled with rain or tap water and a few plants.
Within weeks, insects arrive by air, birds drop in for a drink, and frogs may move in from nearby. Seeds and tiny creatures hitchhike on wind, feet, and feathers. A wildlife pond needs sunlight, native plants, and one sloped side so animals can climb out. Young children should always be supervised near any pond.
