Estimated dates of (A) flowering and (B) senescence of cheatgrass, and (C) flowering and (D) senescence of red brome for 2019

Estimated dates of (A) flowering and (B) senescence of cheatgrass, and (C) flowering and (D) senescence of red brome for 2019 calculated using photothermal time models and daily gridded Daymet climate data from 2019 and then adjusted by continuous heat-insolation load index. Phenology model projections were clipped to the estimated suitable habitat boundaries for each species from the invasive plant habitat suitability webtool INHABIT (Jarnevich et al., 2023, https://gis.usgs.gov/inhabit/).
