Fig. 3: PA effectiveness estimates derived from hurdle-mixed models.
From: Assessing the effectiveness of a national protected area network for carnivore conservation
Marginal regression coefficients (colored dots) and 95% confidence intervals (arrows) from hurdle-mixed models for the impacts of PA (as well as additional matching covariates and interactions) on (a) bear, (b) lynx, (c) wolf, and (d) wolverine densities (n = 1126 unpaired sampling units). (Estimates of covariates having a positive effect on carnivore densities are represented in green and estimates of covariates having a negative effect on densities are represented in black).
