Summary
This summer, Gina Collignon and I worked with Dr. Eric
Berlow on a preliminary study of pack stock impacts on alpine meadows
in the Sierra Nevada Mountains. It was a great way to experience ecological
research in a beautiful environment! We did transect surveys of two meadows
in the Fish Creek Basin: Duck meadow and Ram meadow. In these two meadows,
we found that more common impacts like sod fragmentation tended to be
less severe, and that rarer impacts like rills and gullies tended to be
more severe. In Ram meadow, we found an association between impacts and
water sources and wet areas of meadows. Finally, we got the chance to
use the spatial software ArcView to visualize these impacts across the
landscape. All in all, it became clear that there is a need for much more
research on alpine meadows and their use by pack stock and hikers in order
to back policy decisions up with sound science.
