The study of Natural History at Harrow is, to a large extent, undertaken by Conservation which meets on a Wednesday afternoon. Identification and surveys of plants, animals and fungi on the School estate are carried out on a regular basis and the timing of seasonal events are recorded and entered into a national database.
In addition to the work of Conservation, occasional talks and trips are organised under the auspices of the Natural History Society, which are open to all boys who might be interested.
