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

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.
2024 “first leaf” date anomalies across the United States relative to (a) 2023 and (c) the 2011–20 baseline, estimated using the USA National Phenological Network (USA NPN) extended Spring Index (SI-x) model ( Day of year of spring (green shades) and autumn (orange and yellow) vegetation phenology indicators for (a),(b) Harvard Forest, Massachusetts, derived from PhenoCam (PC), ground observations (GO) of red oak (Quercus rubra), and the USA National Phenology Network (USA NPN) regional-scale means of red oak observations (calculated across the northeastern states of Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, and Maine, with ±1 std. error shaded)

@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.

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!

Today I got to witness a 5' gopher snake devour a young dove right from the nest - wow! #nature

Hi Henricus, it's been a while! good to reconnect!
theresacrimmins.bsky.social
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!

Yes you can download raw data from this tool: data.usanpn.org/observations...

And for the API-friendly folk, we have an R package (rnpn) and APIs for accessing our data too - more here: www.usanpn.org/data/code

Good question! All #phenology observations contributed to #NaturesNotebook are readily available! You can explore via a visualization tool: data.usanpn.org/vis-tool/#/ or download through an online query tool: data.usanpn.org/observations...

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.

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

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...
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...

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...
