Brief Description: The Age-Only BDA module simulates tree mortality following major outbreaks of insects and/or disease, where major outbreaks are defined as those significant enough to influence forest succession, fire disturbance, or harvest disturbance at landscape scales. This version of the BDA will work with both age-only and biomass succession in LANDIS-II. However, it only uses cohort age information. Partial cohort removal and growth reductions are not possible. This implementation therefore behaves similar to that described in the Sturtevant et al. (2004) paper, and in the LANDIS 4.0 User’s Guide, with the exception of a variable temporal resolution where cohort ages are not limited to 10-year time steps.
