The @usa-npn.bsky.social team will be celebrating #Pheology Week Mar 16-20 to coincide with the Spring Equinox. Join us for some fun and educational opportunities to celebrate the start of the spring season! www.usanpn.org/news/article...

All that cold the L48 recently experienced really slowed down the onset of spring. But we are starting to see things pick back up, with extra-early activity in the TX panhandle and through parts of AZ, CA, and up the west coast #statusofspring www.usanpn.org/data/maps/sp... @usa-npn.bsky.social

Predict when cherry trees will flower at locations around the globe and win prizes! Both remote and in-person participation opportunities this year! #phenology #ecologicalforecasting #statistics #statusofspring competition.statistics.gmu.edu

Our maps of heat accumulation provide a more scientific look at how much heat has accumulated so far this year. Our maps show that heat accumulation is ahead of schedule in much of the west, on time in the Midwest and upper Northeast, and behind schedule in the East.

According to predictions from NOAA's Climate Prediction Center, Phil may be right for parts of the Northern Great Plains - more cool temperatures are on the way! Much of the SW and SE should see above-avg temps in coming weeks and the NW, MW, and NE should see avg temps.

To watch the progression of spring across the country, check out our spring forecast maps - updated daily! usanpn.org/data/maps/sp...

Punxsutawney Phil has made his annual prediction of what the next six weeks of weather will bring. According to Phil, more winter is on the way! But what does the science say? #GroundhogDay Keep track of Spring's arrival: usanpn.org/data/maps/sp...

Cedar fever got you feeling crummy? @usa-npn.bsky.social is collecting of Ashe's juniper pollen development and release through the NASA-funded PollenCAST project! Your observations of when junipers release pollen in TX will support real-time forecasts of airborne pollen usanpn.org/nn/campaigns...

And we're off! Spring has started to arrive in the most southern states, and in parts of TX, LA, and MS, it's >two weeks earlier than "normal" (the last 3 full decades). I feel like a broken record, we say this nearly every spring... #phenology @usa-npn.bsky.social usanpn.org/data/maps/sp...

Awesome @usa-npn.bsky.social partners Toby Ault and Carlos Carillo at @cornelluniversity.bsky.social released their long-lead forecast for spring; they are predicting a pretty early start to springtime activity in much of the U.S. six-ecrl-24.s3.amazonaws.com/index.html #phenology

Spring wildflowers are blooming earlier than in the 1800s... and it's the ones that flower earliest in the season that are showing the greatest shifts in their activity. Great work by Ryan Utz, @jmheberling.bsky.social, and crew: www.alleghenyfront.org/early-spring... #phenology

Writing for NYT, Margaret Roach looks at changing landscapes & weather patterns with new eyes, referring to "Phenology" author Theresa Crimmins' advice to "weave a practice of observing seasonal cycles of plants and animals into your life to contribute to science as well as soothe your soul":

Calling #NaturesNotebook participants! We have an opportunity for 18 observers to be interviewed by undergraduate students at UCLA this spring. The observer profiles will be featured on the @usa-npn.bsky.social website and in future newsletters. Interested? docs.google.com/forms/d/e/1F...

Amen! New Rules for the New Year www.nytimes.com/2025/12/31/r... #phenology #climatechange #sustainability #keepingittogether

December is a time when ‘… of the Year’ pieces appear in all kinds of publications. Nature Plants joined the trend, highlighting the importance of ground-based observations, like the @usa-npn.bsky.social 's plant and animal #phenology reports, in ground-truthing www.nature.com/articles/s41...

Definitely don't miss the virtual gathering of folks involved in tracking #phenology in the U.S. in Jan - it's going to be great!

goodmenproject.com/featured-con... Mt Auburn is a really special place, and their volunteers that track #phenology and other phenomena are really special people!

Amazing interview with Amanda Wanlass, Executive Director of Indiana #Phenology! www.wishtv.com/beo-show/loc...

I had such a great time at the Colorado Native Plant Society meeting this past weekend! Made some great friends and enjoyed seeing some glimpses of fall color 🍂#phenology

Applications now open for our Local Phenology Leader Certification Course, an interactive, online 10-week course on planning and implementing a long-term phenological monitoring program for your organization or community. Course runs Sep 29-Dec 5. Apply by Sep 21. www.usanpn.org/nn/LPLCertif...

The 2024 #BulletinAMS State of the Climate Assessment is out today. @usa-npn.bsky.social contributed data & info about how #phenology is changing in the U.S. The timing of plant and animal activity such as leaf-out is a strong indicator of species and ecosystem response to changing conditions.

Hooray @lpzoo.org! Congrats on 5 years of #phenology observations on native hibiscus! www.lpzoo.org/phenology-an...

Thank you so much, Michelle Sutton, for the wonderful review of my book, _#Phenology_, in City Trees Magazine! read.dmtmag.com/i/1537178-ju...?

Now, as always, getting outside is good for you and your mood. Thankful for the opportunity to write for Arizona Daily Sun. #phenology azdailysun.com/opinion/colu...

@jeremyclark.bsky.social helped the @usa-npn.bsky.social explore options for generating commercial revenue. It's tough for programs exist to serve the public. I hope our experience can help other programs suddenly struggling with $ loss. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

It's not uncommon for spring to start out early and then slow down, or vice-versa... see where either of those sequences of events occurred in the L48 states this past spring: www.climate.gov/news-feature... #phenology @usa-npn.bsky.social @climate.noaa.gov

Call for papers! Special issue in new @SpringerNature journal _Discover Life_ : Plant #phenology in an era of rapid global change: new perspectives and frontiers. Co-editing this collection with the fabulous Rob Guralnick and @diji.bsky.social link.springer.com/collections/...

Join us for a talk by Theresa Crimmins on how we can all participate in documenting the timing of seasonal life cycle events—with benefits including mental health and supporting climate change action! @theresacrimmins.bsky.social @usa-npn.bsky.social

No need to dig for your next read: @empressofdirt.bsky.social provides recommendations from her #garden and #nature bookshelf, including "Phenology" by @theresacrimmins.bsky.social and "The Urban Naturalist" by @schilthuizen.bsky.social:

I invite you to track seasonal changes in plants and animals -- #phenology -- in your yard, to support science, and more importantly, because it is good FOR YOU. Excited to share my #TEDxUofA talk from last October: youtu.be/3l0fMlv2-5Q

Really nice to have @empressofdirt.bsky.social mention my book, #Phenology, on her spring book list! Thank you! empressofdirt.net/reading/

Thanks for digging this out of the archive! #phenology

Spring didn't really start out very interesting (arriving later than average in much of the south & west), but is showing up early in the middle of the country and creeping into the NE early now! #phenology #statusofspring @usa-npn.bsky.social www.usanpn.org/data/maps/sp...

First signs of spring make their way northward across the U.S. www.climate.gov/news-feature... #phenology @usa-npn.bsky.social

Thank you so much, @m-kebell.bsky.social! Are you seeing any signs of spring yet? It's been sooooo dry here, but still there are some encouraging things to note - I'm having to look at bit more closely to see!

In anticipation of the first day of spring, The New York Times interviewed @theresacrimmins.bsky.social on the subject of her new book, "Phenology," and how gardeners can piece together a more textured sense of spring's start from real-time clues found in their backyard:

Excited for this event next week! Not too late to register! And it will be recorded, in case this time isn't great for you :) #phenology

Watching for signs of spring increasing desperation...because nature can soothe our weary souls. #phenology www.nytimes.com/2025/03/12/r...

We are seeing a real herky-jerky start to spring this year! Things might finally start picking up in the middle of the country after a long, cold spell... but the start to the season definitely is not notably early #phenology Learn more: www.usanpn.org/data/maps/sp...
