Introduction
For most people who visit Epping Forest the ponds and lakes are a place to enjoy the ducks and
geese. However, my interests in these waters are not primarily with the larger life forms but those
that can only be discerned with the aid of a microscope. A microscope, which may cost a few
hundred pounds, can reveal a new world that can keep the naturalist/student busy for many years.
Investigating protozoa in ponds
Most of the ponds that are found in Epping Forest are artificial. The flora and fauna of the pond can
change rapidly depending on weather, chemistry and time of year. It is always a pleasant surprise
when fresh and interesting life forms present themselves, all with an interesting life story to unfold.
Please remember to take only what you need, a few jars with a small amount of algae and mud will
hold enough micro-organisms to keep you busy for quite some time. And remember not to place the
catch in direct sunlight and to make your observations as soon as possible.
