Does spring index predict arbovirus season

Comparing the spring indices to our mosquito arboviral data to see if there is a correlation between when spring begins and mosquito and virus activity during the season

Informing property values and power line encroachment

Companies (NearMaps, possibly also EagleView) using high resolution satellite imagery with other data sources to help inform property value assessments want to know phenology so can get images without foliage in the way. May be other applications too, EagleView's TreeRisk is about veg encroachment on power lines.

15 million records submitted to the National Phenology Database

15 million records Nature's NotebookWe've just reached the milestone of 15 million records submitted to the National Phenology Database!


USFWS Refuge Phenology Dashboards

On the USFWS Phenology Network subsite, we created dynamically updating dashboards that display results from phenology data collection for partner refuges.

Si-x in the Refuges and Migratory Flyways

A new study from USA-NPN and USGS researchers published in PLOS One leveraged the USA-NPN's Spring Index models to understand trends in the timing of spring. We found that in recent decades, spring is arriving early in three-quarters of national wildlife refuges and extremely early in half of refuges. These changes are not consistent across the latitudinal extent of migratory flyways, with spring advancing significantly faster in the north for most flyways.

Audubon input on Bird Protocols and Activity Curves Visualization

Audubon CA's BirdSeasons CA observers, along with Sandy DeSimone, provided input on Nature's Notebook bird protocols and in-depth discussions led to the creation of the Activity Curves Visualization.

Phenology at AGU 2018

AGU Fall Meeting 2018



Several staff members of the USA-NPN will attend the Fall Meeting of the American Geophysical Union this December. 

The USA-NPN presentations include the following: 

B44B-01 Forecasting Invasive Species Activity for Natural Resource Planning and Risk Assessment


Managing for more variable springs

Placeholder for SI-x variation work - likely an Acadia example with Nick and others.

Timing pest management

Phenoforecast usage placeholder - what is our best example of this? Update spring 2019?

Timing Street-sweeping in Minneapolis

Homeowners in St. Paul, Minnesota, are tracking the timing of leaf drop in their neighborhoods using Nature’s Notebook. Municipal public works departments will use this information to effectively schedule streetsweeping activities, with the intent of improving the quality of local ponds and lakes.

2018 Active Local Phenology Program Evaluation

Thank you for creating, hosting, and using a long-term Nature's Notebook phenology monitoring program.

Please take a few moments to provide us with some feedback so we can better understand the impact your program is having.  We value you, your efforts and your responses. Happy observing!

USA-NPN's 10-year Anniversary Event

Nature's Notebook "Conflicting Observational Data" Survey

Observational data conflicts in Nature's Notebook occur when there is more than one observer entering data on the same day, on the same individual plant or animal, and each observer submits a different answer (e.g. one person says yes to leaves and another person says no). This places an internal flag on the data in the database.


Walking with Wildflowers, a Local Phenology Program of the USA-NPN is leveraging citizen scientists to collect data along the Pacific Crest Trail. This AAAS blog post by collaborator Nic Kooyers describes how the researchers behind this effort are working with local hikers to understand which high-elevation species may be vulnerable to shifting climatic conditions.

Call for Submissions: The Local Phenology Program PhenoChampions Award!

The National Coordinating Office (NCO) of the USA National Phenology Network recognizes the outstanding achievements of our Local Phenology Program Partners with the annual PhenoChampions Award!

Planning NEON Field Seasons

NEON needs to plan field seasons to capture relevant phenophases. In their training workshops they are using our gridded AGDD products, including the forecasts and anomalies to decide when to visit field sites.

Share your Workshop Resources!

Did you host a fantastic class, workshop, event, or program? Want to share your program or lesson plan with others? We'd love to see what you've made and hear how it went. Use this form to upload and share your agendas, powerpoints, activities, lesson plans, tabling event contents, evaluations, and more.

Tell us briefly how it went and what you'd recommend doing differently if you hosted the event again.

If you have more than one of each of these things to share, you can submit the form more than once.
