Fire Ecology

Table 1 Summary of posterior distributions from the multi-season occupancy model (400-ha scale). Results are organized by sub-model component (detection, initial occupancy, colonization, and persistence). SD standard deviation, LCL lower 95% Bayesian credible limit, UCL upper 95% Bayesian credible limit, f proportion of posterior distribution with the same sign as the mean (i.e., probability of effect being in the direction of the mean). All coefficient values are on the logit scale
