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

Cemeteries: How the Dead Protect the Wild
From wildly popular to nearly forgotten, some of our cemeteries play an unexpected role in fostering biodiversity — and may provide climate solutions, too.

Mt Auburn is a really special place, and their volunteers that track #phenology and other phenomena are really special people!

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.
That's awesome! Thanks, Brian!

Spotlight on Climate: Moments in nature can still soothe your climate-weary soul
And just like that, spring is behind us. The first day of summer will be here this weekend. But around the state, we are lacking some of the classic harbingers

It's tough for programs exist to serve the public. I hope our experience can help other programs suddenly struggling with $ loss.

First blooms of the 2025 spring season were earlier than average across most of the United States
According to a long-term index of flower timing, most U.S. areas saw flowers emerge earlier than average, except for a few, mostly coastal areas.

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:

Hi Henricus, it's been a while! good to reconnect!
Ooooh! Thanks for clarifying :)
Great question! Best bet is to preserve as much detail as you can - for example, rather than only retaining the date you first saw something if you also have dates you *didn't* see something, retain both. Would be happy to have a chat about this, if it would help!

Is Spring Falling Out Of Sync?
The delicate timing between plants, wildlife, and seasons can be thrown off balance by warming temperatures.

First signs of spring make their way northward across the U.S.
While the first day of spring arrives on March 20, many places across the United States see their first signs of the season much sooner. The Spring First Leaf Index, provided by the USA National Pheno...

Yes! This map indicates whether the conditions associated with spring were met early or late this year. They were reached early for a period in the S due to warm temps, then it got cold & things stalled out & conditions were reached late. This piece explains it well: www.climate.gov/news-feature...
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...
