Spatial uncertainty in herbarium data: Simulated displacement but not error distance alters estimates of phenological sensitivity to climate in a widespread California wildflower

Devin Gamble & Susan Mazer
Herbarium records provide a broad spatial and temporal range with which to investigate plant responses to environmental change. Research on plant phenology and its sensitivity to climate has advanced with the increasing availability of digitized herbarium specimens, but limitations of specimen-derived data can undermine the inferences derived from such research. One issue that has received little attention is collection site uncertainty (i.e., error distance), a measure of confidence in the location from which a specimen...
