Preliminary Little Yampa Canyon Field Map Series

John Husband made a preliminary inventory of leafy spurge in the Little Yampa Canyon during 2016, sketching areas of infestation viewed from the river directly onto paper maps. These maps have now been superseded by the YRLSP Leafy Spurge GIS field mapping project.

For a river-mile-by-river-mile report, view John's 2016 LYC Inventory Report.
