purpose This dataset provides Percent Fire Return Interval Departure (pFRID) estimates based on Vibrant Planet's 2023 analytical approach, with data masked to highlight areas of significant departure. Using a p-value derived from a binomial distribution, the dataset only includes pixels where the null hypothesis significance test yields values ≤ 2.5% or ≥ 97.5%. This masking ensures that the dataset focuses on areas with statistically significant deviations from historical fire frequencies, offering a targeted resource for land managers and researchers.The dataset spans 17 western U.S. states, with partial coverage in 5 additional states, providing actionable insights for wildfire management and ecological restoration efforts.
