J.R. Alcorn 1939 Nov. 11 Microtus montanus In Community Pasture, 7mi. SE Fallon, Churchill Co., Nev. This afternoon I went down to the experimental plot of the community pasture where grasses, clover had been planted and not harvested or grazed. My father W. H. Alcorn said many meadow mice were in this location. We set 75 traps and within 1/2 hr. we had two mice. Many runs were noted in the Lesino Clover but in Meadow Fescue (a grass) were few runs, yet both were growing side by side. The Strawberry Clover was growing in a plot next to the Lesino Clover and both clovers contained approximately an equal amount of runways. The Meadow Fescue, Lesino Clover, Strawberry Clover were all in long narrow strips (30 ft.) adjoining each other. The soil texture was about the same on each plot, each had been irrigated the same day by the flooding method. Irrigation took place each week during summer months & less frequent during fall
