Current Research

  • Crowd-sourcing techniques to amass large data sets for use in multi-scale applications such as NorWeST
  • Spatial database management for research on climate change effects on stream temperature dynamics
  • Establishment of stream temperature monitoring networks and methods to quantify long-term temperature trends and increase efficiency of data collection
  • Application of eDNA techniques to determine rangewide bull trout distribution
  • Technology transfer of applied science tools and procedures

Research Interests

I am interested in using data to influence management decisions so that stream habitats are conserved in the face of climate change using the most cost-effective and biologically relevant approaches. I enjoy collaborating and coordinating with resource managers and scientists to create data and information sharing opportunities for the benefit of research and land management. I also find disturbance ecology fascinating, especially the short and long-term effects of wildfire on stream habitat and aquatic communities.

Past Research

Fish habitat inventory procedures and database development, wildfire and prescribed burn effects on large woody debris and other habitat characteristics, and implications of using various fuel reduction practices in riparian areas.

 

Why This Research is Important

In most aspects of fish and fish habitat research, we are not data poor, but rather, lacking in data organization and coordination. Given 1. There are huge quantities of historical data in addition to continuing data collection, 2. The massive expenditures associated with such data collection, and 3. The vital importance of long-term, and spatially explicit and extensive data sets, it only makes sense to tap these data to address time-sensitive conservation questions that require large long-term and reliable data sets.

    Anyone familiar with the Columbia River’s massive salmon die-off a few summers ago might also be concerned about how climate change will affect fish habitats. The 2015 die-off killed more than 250,000 fish and was blamed on record low streamflows and high water temperatures. While coldwater fish such as salmon and trout can adjust to slightly warmer-than-normal temperatures for short periods, abnormally high temperatures for prolonged periods lower oxygen levels, increase the likelihood of deadly diseases, and cause life-threatening physiological stress.
    The website provides: 1) A large list of supporting science behind eDNA sampling. 2) The recommended field protocol for eDNA sampling and the equipment loan program administered by the NGC. 3) A systematically-spaced sampling grid for all flowing waters of the U.S. in a downloadable format that includes unique database identifiers and geographic coordinates for all sampling sites. Available for download in an Geodatabase or available by ArcGIS Online map. This sampling grid can be used to determine your field collection sites to contribute. 4) The lab results of eDNA sampling at those sites where project partners have agreed to share data.
