THREATS

Loss and fragmentation of habitat appear to be the main historical causes of decline for the Buena Vista Lake

shrew. Conversion of historical range to agricultural land has sharply reduced the available habitat.

The few remaining populations of Buena Vista Lake shrew are cut off from each other, and thus more

vulnerable to environmental perturbations such as fire, drought, and disease. Habitat alterations such as

removal of dense vegetation or drying of marshy areas could also threaten the subspecies.
