Natures Note Book Project new letter up date!

Greetings! It seems like each week brings new challenges these days! Many of you will be busy getting kids set up with school, either online or in person, starting the college semester, or just holding things together! Outside, plants and animals continue their seasonal cycles, reassuring amid these uncertain times.  We are so grateful to see your observations continue to roll in. The data that you collect are critical to our understanding of how plants and animals are responding to environmental changes from hurricanes to extreme heat to wildfires. As many research efforts have been put on hold or otherwise impacted by the COVID-19 pandemic, your data are more important than ever in documenting phenology. Below are a few examples of how researchers are using your data and how you can explore the data yourself through our Visualization Tool.  Stay safe and hang in there!  What your data are telling us Invasive species have the upper hand Invasive shrubs are overwhelming native shrubs in eastern states. Researchers have suspected that early leaf out and late leaf fall gives invasives shrubs an advantage over natives.  In 2015, we worked with Penn State researcher Erynn Maynard-Bean to create the Shady Invaders campaign to document this phenomenon of extended leaf phenology. Over three years, 800 Nature's Notebook observers in 20 states contributed data on invasive and native shrubs across the Eastern U.S. Dr. Maynard-Bean recently published her results with colleagues in Biological Invasions. This knowledge will aid managers in targeting invasive shrubs with early leaves in the spring and late leaves in the fall for removal and treatment.

Check out this great short video from KARE 11 in Minneapolis, MN that explains why this campaign is important and how folks in the Midwest and Northeast can get involved. Watch the video » What's new at Nature's Notebook and USA-NPN Explore Seasonal Stories on the Viz Tool Our Seasonal Stories show you examples of what we can learn from the plant and animal phenology data that you contribute to Nature's Notebook. Find out whether invasive shrubs leafed out earlier than native shrubs in the Eastern U.S. this year, whether White-winged Doves arrived in time to feed on saguaro flowers in Arizona, and whether maples leafed out earlier at southern latitudes than northern latitudes.  Explore Seasonal Stories » Recent happenings in the field of phenology Allergy season and the start of spring In order to see whether the timing of spring onset is associated with rates of asthma-related hospital admissions, a team of researchers looked at hospitalization data, the timing of spring as measured by satellite data, and pollen monitoring data to determine the length of pollen season. They found that early spring was associated with a 17% increase in hospital admissions for asthma, while a late start of spring was associated with a 7% decrease. Researchers can use information about the timing of spring season to anticipate the severity and timing of allergy season, providing personalized early warning systems that may reduce asthma hospitalizations.

A new study from researchers at University of Wyoming found drought can shorten the duration of spring green-up, which may be a new threat for migrating deer. Learn more » Nature's Notebook Nuggets When does a leaf count as colored? When it comes to reporting on colored leaves, any amount of color (regardless of the reason) means a 'yes'. If reporting on intensity, consider the percent of color in the canopy respective to the canopy at 100% potential fullness—and it might take a year to know what this looks like for your plant.  Learn more » See all Nature's Notebook Nuggets » More ways to get involved Indigenous Speaker Series We've seen a lot of interest recently in indigenous approaches to ecology and phenology, including the Indigenous and Western Approaches to Phenology NCTC series that we co-organized with the Indigenous Phenology Network and the Indigenous Phenology and other Indigenous-focused sessions at the Ecological Society of America meeting.  If you'd like to learn and connect further in this area, two great options are the NWIC and UW Indigenous Speaker series and Rising Voices. Learn more » Indigenous knowledge aids stewardship A million species across the globe are threatened with extinction, according to a preliminary report from the United Nations. The report also found that biodiversity is declining at a much lower ate on lands governed by indigenous peoples. An article from Scientific Americandiscusses how Traditional Ecological Knowledge is complementary to western science in supporting sustainable management and maintaining biodiversity.
