Despite a strong anthropogenic fingerprint on 20th Century wildland fire activity in the American West, climate remains a main driver. A better understanding of the spatiotemporal variability in fire-climate interactions is therefore crucial for fire management. Here, we present annually resolved, tree-ring based fire records for four regions in the American West that extend back to 1400 CE. In all regions, years with high fire activity were characterized by widespread yet regionally distinct summer droughts. Overall fire activity was high in late Medieval times, when much of the American West was affected by mega-droughts. A distinct decline in fire activity in the late 16th Century corresponds with anomalously low temperatures during the Little Ice Age and a decline in Native American fire use. The high spatiotemporal resolution of our fire record discloses a time-frequency dependent climatic influence on wildfire regimes in the American West that needs to be accounted for in fire models. STUDY NOTES: These fire-scar records were provided via a USDI/USDA Interagency Joint Fire Sciences Program database project (Taylor, A. H., C. N. Skinner, A. M. Carleton, and S. L. Stephens. 2007. Fire climate interactions and predicting fire season severity in the Mediterranean climate areas of California, southern Oregon, and western Nevada. Rep. 03-1-1-22. Joint Fire Sci. Program, Boise, Idaho.). Fire scar-records were selected from individual trees that were recording fire prior to the year 1500. These records were compiled from data from the following original sites: Site Name, Latitude (degrees N), Longitude (degrees W), Principal Investigator Adin Pass,41.34,120.99,Skinner Bluff Lake,41.34,122.55,Skinner Cedar Basin,41.22,122.49,Skinner Coggins Saddle,42.15,122.69,Skinner Crater Creek,41.38,122.58,Skinner Dog Valley,39.59,120.03,Taylor El Capitan,37.73,119.76,Taylor Goosenest,41.53,121.85,Skinner Grayback,42.14,123.45,Skinner Hayfork,40.5,123.2,Taylor Lake Tahoe Basin,39.05,119.93,Taylor Prospect Peak,42.56,121.69,Taylor Stampede Reservoir,39.45,120.13,Taylor
