You can now explore gridded maps of the Spring Indices and Accumulated Growing Degree Days for Alaska on the USA-NPN Visualization Tool. Spring arrived in coastal areas of the southern part of Alaska in April, and is moving north across the state.
If you live in Southeastern Arizona, you can help the US Fish & Wildlife Service document flowering of agave and saguaro cactus during the spring and summer flowering periods, an effort called Flowers for Bats. This information will be used by the FWS to conserve and promote habitat for lesser long-nosed bats. Observers in other areas can visit the Nature's Notebook campaigns page to find out how to participate in other campaigns.
