USA National Phenology Network
October 6, 2016
The USA-NPN is part of a new study published in Ecosphere that shows spring is advancing in 75% of 276 National Parks studied. This shift is "extreme" in half of the Parks. The study used the Spring Indices, an index of spring developed by the USA-NPN and its partners. Secretary Jewell announced the study at Shenandoah National Park, and an Arizona-focused article appeared in UANews.
The first section of the Phenophase Primer is now available for download. This beautifully illustrated guide provides detailed information on how to identify each of the phenophases we ask you to observe on the Nature's Notebook datasheets. Please note that this is a draft version; a final version with information about conifers and more photos will be released next year. Once all three sections are complete, we will offer a printed and bound copy, much like we do for the popular Botany Primer.
