Principal components (PC) analysis ordination diagram of the six most prevalent, non-correlated sedimentary pollen taxa (dark brown) from Markwood Meadow, California, USA. Distance biplot shows dated pollen sample points, where dates are mean calibrated age assigned from the age-depth model rounded to the nearest decade. Modern (1850–2019; dark grey dates). LIA = Little Ice Age (1200–1850; blue dates). MCA = Medieval Climate Anomaly (900–1200; orange dates). Pre-MCA (400–900; purple dates)
