Riparian vegetation along streams provides a suite of ecosystem services in rangelands and thus is the target of restoration when degraded by over-grazing, erosion, incision, or other disturbances. Assessments of restoration effectiveness depend on defensible monitoring data, which can be both expensive and difficult to collect. We present a method...
Stronger peak ground motion, beyond the threshold to initiate a response, does not lead to larger stream discharge responses to earthquakes
Christian H. Mohr, Michael Manga, David J. Wald
2018, Geophysical Research Letters (45) 6523-6531
The impressive number of stream gauges in Chile, combined with a suite of past and recent large earthquakes, makes Chile a unique natural laboratory to study several streams that recorded responses to multiple seismic events. We document changes in discharge in eight streams in Chile following two or more large...

Mathieu Bonneau, Regis Sabbadin, Fred A. Johnson, Bradley Stith
2018, PLoS ONE (13)
Conversion of wild habitats to human dominated landscape is a major cause of biodiversity loss. An approach to mitigate the impact of habitat loss consists of designating reserves where habitat is preserved and managed. Determining the most valuable areas to preserve in a landscape is called the reserve design problem. There exists several...
Value of sample information in dynamic, structurally uncertain resource systems
Byron K. Williams, Fred A. Johnson
2018, PLoS ONE (13)
Few if any natural resource systems are completely understood and fully observed. Instead, there almost always is uncertainty about the way a system works and its status at any given time, which can limit effective management. A natural approach to uncertainty is to allocate time and effort to the collection...

Outburst floods provide erodability estimates consistent with long-term landscape evolution
Daniel Garcia-Castellanos, Jim E. O'Connor
2018, Scientific Reports (8) 1-9
Most current models for the landscape evolution over geological timescales are based on semi-empirical laws that consider riverbed incision proportional to rock erodability (dependent on lithology) and to the work performed by water flow (stream power). However, the erodability values obtained from these models are entangled with poorly known conditions...
