Comparison of variable weights from 2 datasets for grizzly bear local abundance.

Importance (weight) of variables influencing grizzly bear abundance in northwestern Montana, USA, in 2004. Only candidate variables for abundance, not detection, are shown. Weights for variables that were in the model ≥50% of iterations are in bold. Data include only cells with both types of sampling. HT = Hair Trap, BR = Bear Rub. See Graves et al. (In Review) for more details on specific variables. We did not include further details to maintain focus on the influence of different detection methods.
1Experts assigned a value 1–10 to ownership categories based on efforts to protect bears including 1) attractant storage management, 2) enforcement of food storage regulations, and 3) road density and use management. Glacier National Park = 10, US Forest Service = 7, other public land = 3, and private = 1.
