Mammals
Mammals
We seek to understand the distribution and abundance of mammals. Several monitoring projects are underway.
Elk- Elk numbers fluctuate through the year with herds of several hundred animals moving onto the ranch in the fall and winter. Fewer elk stay around to raise their calves in the spring and summer. We track herd size, the habitat they use for feeding, and the amount of biomass available to them for forage. We are curious about how elk habits will change in response to changes in vegetation communities as restoration activities proceed.
Bears- The lower elevation draws and drainages at MPG were de-vegetated by herbicide applications and sheep and cattle browsing. As of the summer 2012, we have planted more than 30,000 trees and shrubs in these drainages. The plantings will provide cover for animals using the draw bottoms as travel corridors between the upland forests and the floodplain forests. Many of the shrubs we have planted, such as hawthorns, choke cherries, and serviceberry, will provide food for bears. Our bear monitoring efforts seek to document how many bears we have now and where they travel.

We would like to do more small mammal research. Please contact us with ideas for collaboration. (Click here to contact us.)
Research Methods:
DNA extractionWe primarily use PCR DNA extraction.
Polymerase chain reaction (
PCR) is a technique used in
molecular biology to
amplify a single copy or a few copies of a segment of
DNA across several orders of magnitude, generating thousands to millions of copies of a particular
DNA sequence.
