High risk of extinction across the flowering plant tree of life

Global biodiversity policies recognize the necessity to preserve evolutionary lineages as their diversity underpins current and future benefits to people and the future of life on earth. Plants are mostly absent from global biodiversity assessments resulting in a taxonomic imbalance that has undermined their conservation for decades. We present a tree of life and extinction risk estimates for all species of angiosperms, representing a global assessment of their threatened evolutionary history. We estimate that 21.2 % of angiosperm evolutionary history is at risk of extinction and identify 9,945 priority species that disproportionately account for total threatened evolutionary history. These prioritizations serve to redress imbalances between plants and animals, monitor conservation effectiveness, and optimize resource allocation in the face of increasing human pressures on biodiversity.

## Description of the data and file structure

The following provides all the data used to compile EDGE scores for all angiosperm species, including the cleaned backbone tree with missing families imputed, the list of missing genera, the 200 draws of extinction risk predictions, the 200 complete species-level phylogenetics trees, and the 200 extinction-risk-weighted species-level phylogenetics trees. It also includes the comprehensive results obtained from these compilations, including the EDGE scores for each species and associated data (Data S1-S2) and the EDGE family compilation (Data S3-S4). Details for each data set are as follows:

**Data S1:** Complete species list with Evolutionarily Distinct and Globally Endangered (EDGE) scores and rankings, including EDGE species, based on the compilation of EDGE scores considering both Internatio...,
