Overview Pre-CanLaD v2 updates Canada's 1965-1984 forest disturbance history dataset initially published by Correia et al. (2024) with enhanced detection methods and improved temporal accuracy and coverage. 2. Key Updates in pre-CanLaD v2 2.1. Enhanced Detection Fractional land-cover change analysis identifies post-disturbance forest regeneration using 1985-2020 vegetation cover differences Dual detection approach combines automated polygon-based classification with manual photo-interpretation Incorporates National Burn Area Composite (NBAC; Skakun et al., 2022) 1972-1984 fire perimeters for improved fire year attribution 2.2. Detection Results See Table 1 in the update report, available in the download section below. This table presents the total disturbed areas, by disturbance type, for the periods 1950–1964 and 1965–1984. The “New detection” column represents disturbed areas for which no reliable previous data were available. The “Previously recorded” column represents disturbed areas already documented in the datasets described in Table 3 of Correia et al. (2024) and NBAC, for which the predicted disturbance year was subsequently adjusted. 3. Dataset description Four…
