Unmanned Aerial Vehicle Based Vegetation Mapping, Middle Fork John Day

In early June, doctoral candidate Aaron Zettler-Mann and recent baccalaureate graduate James Major spent three days flying a UAV on the Middle Fork of the John Day. The object of the project was to produce an orthophotograph of floodplain vegetation along a 2.5 kilometer by 0.5 kilometer section of the Middle Fork Valley Floor. The orthophoto will be used to map distinct vegetation species on the floodplain, with species identification occurring in the field. The resulting floodplain vegetation maps will be compared to previous field surveys of floodplain vegetation dating back as far as 1996. Additionally, this map will serve as baseline vegetation data going forward. Active channel restoration occurred beginning in July of 2017 and the vegetation map will allow future monitoring of floodplain vegetation communities which are a good indicator of changes to ground water flow. Below, the orthophoto compose for the study area and some pictures from the ground of vegetation and floodplain terrain.
