Collection Overview: NCALM Seed Project PI: Rebecca Lloyd, University of Arizona. The survey area is two experimental watersheds, Shotgun Creek and Twin Creek located in the Clearwater National Forest of Northern Idaho. These areas are roughly 70 km southwest of Missoula, MT. The survey polygon for Shotgun Creek is approximately 15.8 square kilometers and for Twin Creek is 26.34 square kilometers. The data were collected to study the effects of watershed restoration on hillslope stability and ecohydrological functions.Publications associated with this dataset can be found at NCALM's Data Tracking Center
