Great Basin Pocket Mouse
(Perognathus parvus)
Great Basin Pocket Mouse
The Great basin pocket mouse is restricted
in Montana to the extreme southwestern
portion of the state. Occupied habitats are
arid and sometimes sparsely vegetated.
Conservation concerns include: competition
for grasses (livestock probably compete with
pocket mice for grasses and reduce shrub
and grass cover); habitat loss by large-scale
removal of sagebrush; and lack of biological
information. Conservation strategies include:
managing land to maintain a mosaic of
sagebrush cover, size, and age classes,
especially if it promotes the growth of
grasses and forbs within sagebrush stands;
rotating livestock areas; and considering
a management plan for the great basin
pocket mouse or including it in another
comprehensive taxonomic plan.
