Biotime or biological time runs at a very different pace or rhythm to human time. It can be observed by recording events in the natural world. These can be as varied as the day the first spring bulb opens, the last frost before summer, or the first sighting of a species of bird or insect in a new habitat. These events can be part of a larger natural rhythm, like the turning of the seasons, or an indicator of slow changes in an ecosystem, like unusual weather patterns or an increase of average temperatures. Gardeners find documenting weather events, especially the first hard frost of the year, very useful. It helps us plan our planting and alerts us to the need to protect our crops. Nature watchers too like to compare notes year on year to record natural rhythms like the migration times of birds and unusual events. On a larger scale, we can also reflect on our own biological rhythms relating to the waxing and waning of the moon and the seasons.
The Biotime Log provides a sound introduction to biotime and how to keep your own log. Beautifully illustrated, this ready-made book will last for years. Two days are allocated to each page in a month-by-month annual cycle. Over time, by recording events year after year, you build a fascinating record of your local natural world and its rhythms and mysteries. Your observation will deepen your connection with the natural world around you, your understanding of its cycles, and your appreciation of your local ecosystems.
