Lilacs showed very early activity in 2012

Wed, Jan 15, 2014
News

Dedicated volunteers have been tracking the phenology of cloned and common lilacs for decades, and these observations have been invaluable in documenting plant responses to changing spring conditions. In 2012, we launched a campaign to garner more commitment among Nature's Notebook participants to tracking lilacs.

Deciduous trees may leaf out weeks earlier under future warming

Wed, Jan 15, 2014
Publication Summary

Warming temperatures are prompting many trees in temperate regions to put on leaves in the spring earlier than they have in the past. Climate change models predict continued warming of up to several degrees C by 2100. A team of researchers at Princeton University, led by David Medvigy, developed a nuanced model to predict the timing of leaf-out in the future.

Data from Nature’s Notebook are bringing landscape change into focus in Alaska

Wed, Jan 15, 2014
Publication Summary

Spring leaf-out phenology observations have proven valuable in predicting how arctic plant communities may change in coming decades. Models used to predict changes in plant communities have traditionally taken phenology into account, but have used a single date for leaf-out averaged across all plant species. As participants in Nature’s Notebook know first-hand, the timing of leaf-out varies by species.

In Memory of Joseph Caprio (1923-2011)

Mon, Oct 31, 2011

Joe Caprio initiated the first spatially extensive phenology monitoring in the United States. As a professor in the College of Agriculture at Montana State University, he collaborated with agricultural experiment stations in the 1950s to employ phenology to characterize seasonal weather patterns and improve predictions of crop yield. This project eventually included around 2,500 volunteer observers distributed throughout 12 Western states.
