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.

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.

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:

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.
