  • To restore riparian vegetation communities and associated values, managers desire a better understanding of the linkages between flow variables and vegetation response.

  • Significant increase in riparian vegetation; riperian vegetation. Big floods in 1983, and has increased since then.
  • 1980 infrared photos show that riparian vegetatin had taken up much of the flood plain down to power plant capacity flow levels.

  • 2013 USGS Report to AMWG--
  • More riparian vegetation exists than in previous 5 decades at the lowest elevation zones (<45k ft3/s)
  • Riperian woody vegetation expanded shoreward
  • HFEs of present magnitude/ duration do not appear to affect the longer term trend of expansion
  • Vegetation change is significantly related to river hydrology at lower elevation zones (<45k ft3/s)and regional climate at higher elevations (>97k ft3/s)
  • Remote sensing datasets allow both large-scale change detection and local-scale analysis to quantify
