F. T. Richardson 1937 3 mi. W Paulina Lake (cont.) June 21, 1937 - Little mention has been made of the mammals of this region as their observation and collection has been second- dary to birds. The ubiquity of Glaucomys mopulus has been noticed. Both Townsendi- sundi and amoenus chipmunks have been collected. Their inactivity in the open on rainy or continually cloudy days has been noticeable. E. townsendii is comfortably far. Last night 46 mouse traps were set out along and on slopes near Paulina Cr. The catch may be summarized thus: 10 traps in timber S of Paulina Cr. -> 2 Peromyscus 12 traps just above steeper S edge of Paulina Cr. -> 1 Peromyscus 14 traps along creek border in Microtus grass + low rushes -> 2 Zapus 10 traps on brushy slopes N of Creek -> 7 Peromyscus The brushy country, and this is the heavily logged area, seems to offer most favorable conditions for Peromyscus. The grass and rushes are limited to the creek's immediate border and Microtus could probably be caught nowhere else. About half of the Peromyscus- are young - early breeding compared to birds, perhaps.
