Additional images of Pogonomyrmex salinus attempting to remove a balsamroot plant (flowerless in this case) from the nest vicinity. Two nest entrances can be seen to the left and behind the plant in the top image. Note that the plant is within the ring of chaff (discarded seed pods, etc.), which usually marks the boundary of the nest-mound for these ants. As previously mentioned, this plant was observed to still be standing two months after these images were captured. Also note the tansy-mustard (Descurainia sp) plant, in upper left of top image.
