Climate, fire, and tree center dates compared. Reconstructions of a ENSO and b Summer PDSI are given at annual (thin lines) and decadal (black lines, 10-year running mean) scales for comparison with fire history and tree establishment. Panels c–e compare relatively large fire events, scarring 10% or 25% of recording samples, with tree center dates by species. Tree center dates are at coring height, 40 cm. Species codes are given in Table 1. ENSO is the reconstructed El Niño-Southern Oscillation index and PDSI is the reconstructed summer Palmer Drought Severity Index. These indices are described in the text
