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

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.

Deciduous trees may leaf out weeks earlier under future warming

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.
