Table 1 Anatomical indicators present (%) on annual ring of fire years for redwoods in two old-growth forests at Montgomery Woods State Natural Reserve (MW) and Landels-Hill Big Creek Reserve (LH). Analysis includes lower-trunk cores with crossdated fire years. Indicator tallied for trees if present on at least one core. If at least one indicator is present, it is tallied for “any indicator” category. IADF means intra-annual density fluctuation.
