Modeled annual seed production estimates for Pinus edulis 1900-2024

These data are gridded estimates of annual seed production (or mast seeding intensity) in a conifer species of the southwestern United States. The extent of these predictions cover the range of Pinus edulis in the U.S. states of Colorado, New Mexico, Arizona, and Utah between 1900-2024. Also included is a map of the variance in bootstrapped predictions for the covered range, and the unpublished training data used in model validation. All other data sources are publically available and free to use. 

Methods
These data were collected with the purpose of validating an established forecast model of cone production in this species. The model was parameterized with existing data on seed production from Wion et al. 2020 (Ecography), and these known relationships between seed production and weather were extrapolated across the range of this species and hindcasted into the past. These data may be used to understand where climatic conditions were most likely favorable to mast seed production in this species for a given year, and where those mast years are likely to have occurred.
