Spring Onset Advancing Across NPS
Spring has already advanced in three-quarters of the 276 parks examined, and half of the parks are experiencing an "extreme" early spring that exceeds 95% of historical conditions as measured by first leaf index and/or first bloom index from indicator plant species.

Is the timing of spring changing across the NPS?
Gridded Spring Indices (Berkeley Earth, Toby Ault version)
