Fig 4. US National Wildlife Refuges with extremely early recent spring onset relative to the historical range of variability.

Shown is the combination of selected data from Fig 3A and 3B; extremely early recent spring onset is defined as earlier than 95% of historical (1901–2012) First Leaf Index (FLI) or First Bloom Index (FBI) values.
