    Friday, January 15, 2016

    new video from NEON Education explains how on-the-ground observations of leaf phenology, camera images and satellite data are integrated to understand phenology across the globe. USA-NPN's Nature's Notebook program is highlighted for its on-the-ground observations of plant phenology at sites across the country.

    Researchers at the University of Twente in the Netherlands have described a new workflow to identify inconsistencies in data collected by volunteers. The method, published in PLoS ONE, will increase the usability of these data. 

  • New study predicting permanent early spring uses USA-NPN's Spring Indices
    Wednesday, October 14, 2015

    Researchers at UW Madison are predicting that early springs could become permanent in the face of climate change. The study uses the Extended Spring Indices, which were created based on historic cloned lilac data housed in the National Phenology Database. Implications of early springs include mismatch between animals and the plants on which they depend, as well as "false springs" that may cause extensive damange to plant growth inlcuding agricultural crops.
