| Summary: | Field data and observational records emphasized three themes for research: a) behavior of individual animals (by sex and age) and groups of caribou (by size and composition) in the vicinity of man-made obstructions, b) reactions of caribou presented with deflection or choice situations, that is, when in proximity to an alternate method of passage over or under the pipelines, and c) reaction of maternal cows and calves when confronting similar structures. The responses of animals on subsequent encounters with the pipelines were studied for insights on the learning ability of caribou to pass beneath or over obstacles.
