Adapting species risk assessments to a changing climate: the underestimated vulnerability of foundational trees

This dataset supports a systematic review and risk assessment of 27
endemic and near-endemic California tree species under projected climate
change. It comprises two supplementary tables. Table S1 contains 52
records of species distribution model (SDM) outputs drawn from the
published literature, organized by species and source study. For each
record, the table includes the species' Latin and common names, the
citation, climate models and emissions scenarios used, the type of
distribution data (presence-absence), baseline period and year, and
projected percent contraction in climatically suitable habitat at
mid-century (~2055), end-of-century (~2100), and ~2125 time horizons,
reported as low and high estimates. Projected values are standardized to
common reference years to enable cross-study comparison. Table S2 provides
species-level summary data for all 27 focal species, including total range
area (km²), the proportion of range occurring within California, mean
projected habitat loss and area of persistence across time horizons and
estimate ranges, a demographic change score synthesizing field-observed
responses to climate change, and climate risk scores corresponding to IUCN
Red List Criteria A3 and B1. Risk scores are reported both across all
studies and separately for a focal subset (Rose et al. 2023).
