Lower-trunk radial growth increment for ten redwoods at Montgomery Woods State Natural Reserve (MW; 1953 to 2015) and Landels-Hill Big Creek Reserve (LH; 1950 to 2016). Black lines represent calculated growth increment using crossdated cores at or below buttress. Blue lines represent the predicted growth increment based on the strongest climate drivers. Red lines represent the residuals centered on zero. Red circles mark fires at 2008 for MW, and 1985 and 1999 for LH.
