Natures Notebook for iOS

Nature's Notebook is a citizen science program for observing and recording plant and animal life cycle events, like flowering and bird migration (also known as phenology). We recommend that you create an account, and register your location, as well as the plants and animals you'll observe online at www.usanpn.org first, and then use this app for going out into the field to record your observations through the seasons. Find out more at www.usanpn.org/participate/observe.
