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.

Every March I end up on the phone with Theresa Crimmins of the @usa-npn.bsky.social National Phenology Network talking about the advent of spring. So when she said she wrote a book, I had to get it and add it to my summer list of books by people I know: www.barnesandnoble.com/w/phenology-...

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

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

Some updates from our Green Wave campaign! 🌱💚

Here's a Status of Spring Update🪻 All states are now seeing signs of spring! Maine still has minimal activity, with some areas seeing leaves a few days later than expected. Signs of spring in the West are still variable, with some places seeing leaves earlier than average and some later.

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...

The Northeast is finally seeing signs of Spring! Leaf-outs have been spotted as north as NY and MA about a week earlier than average.

Check your redbuds for blooms! 🌸 Some updates: Looks like you're seeing a higher proportion of flowers so far this year than last year. You're also seeing open flowers and young leaves earlier than last year.

Check out this Status of Spring update! Leaf out activity has expanded to more northern Midwest states like Nebraska and Iowa, with most of them seeing leaves earlier than the 20 yr average.

Tomorrow at 2pm eastern! Come ask me questions about how to use @usa-npn.bsky.social data in phenological research! #phenology #spring

Phenology week is coming @usa-npn.bsky.social! March 18, I'll be talking about Quercus Quest campaign for eastern North American white oaks, w/ Kim Pegram on Desert Refuge: Monarchs and Milkweeds and Nicholas Dietschler on Pest Patrol. Info and registration below: www.usanpn.org/news/article...

What interesting and exciting common garden / reciprocal transplant experiments do you know of? Who is conducting them? I'm interested in connecting with folks as we continue to work on our climate-focused bur oak experiment in OK, IL and MN w/ @cavenderg9.bsky.social, Heather McCarthy & colleagues.

Things are heating up in the Southeast! This is your weekly Status of Spring update 🌿 Spring leaves have continued to spread from the lower half of the Southeast upwards, with the lower half seeing lead outs later than average and the upper half seeing them earlier than average.

Need a break from the news? Getting outside helps... it's a great time to start observing #phenology. Just in time, @usa-npn.bsky.social has released the Phenophase Primer, an extraordinary 240-pg resource that addresses all of your questions. Download for free: usanpn.org/news/article...

This week's Status of Spring has already changed significantly since last week's, with the lower half of all southeastern states now experiencing spring leaves. Parts of AZ and CA are seeing leaf outs as well, with AZ's coming a bit later than average and CA's coming earlier.

Each year, people gather to hear Punxsutawney Phil's prediction of what the next six weeks of weather will bring. This year, Phil saw his shadow this morning and predicted six more weeks of winter! But what does the science say? Keep track of Spring's arrival: usanpn.org/data/maps/sp...

What do you predict Punxsutawney Phil will decide for Groundhog Day this Sunday? You can use your phenology observations, such as early/late leaf outs for your plants, to comment your prediction below. Comment 🌸 for early spring and ❄️ for six more weeks of winter!

It's time to start tracking the Status of Spring! While the U.S. has yet to see any blooms, Florida has begun seeing some spring leaves. We'll be providing weekly updates on the Status of Spring, so keep your eye out for spring activity near you!

Here we go with tracking the start of spring! So far, spring leaf out is up to 10d late in southern FL and TX compared to long-term avg (1991-2020). Spring arrival is variable in CA & AZ, arriving 5d late to 2 wks early. Track spring: www.usanpn.org/data/maps/sp... @usa-npn.bsky.social #phenology

We love when this happens! Feel free to observe all animals that interact with your plant, and vice versa 🦋 - Inspired by @americaswildliferefuges on Instagram!

Happy Holidays from Oklahoma! Fall is in full force here, and the difference between the phenology of these two plants next to each other in my family's yard amazing! If you can, go outside and compare and contrast the phenology of two plants near you today. 🍂

Alright, if everyone is putting together starter packs, here are some accounts to follow if you're interested in #phenology and how #climateChange affects the timing of biotic interactions! Please let me know if you want to be added or removed from the list 🌱🧪🌎 go.bsky.app/7TjLKe5
