In this multimedia video produced by the Wisconsin Educational Communications Board, Nina Leopold Bradley recounts how she learned as a child to record first flower blooms and the arrival of birds on her family's land along the Wisconsin River. She introduces the practice of phenology, or the study of the timing of life cycles of plants and animals, and explores evidence of climate change from records her family has kept since 1935.
