<br />001/t95 <br /> <br />Arizona State University initiated field studies on impact of vegetation <br />management upon wildlife along the Lower Colorado River. A progress report <br />to Reclamation on the research program will be provided quarterly. Anti- <br />transpirant spot treatments on the Newlands Project near Lahontan Reser- <br />voir in Nevada demonstrated a reduction in transpiration rates for the <br />first thirty days. <br /> <br />An informal cooperative application of remote sensing to the Bernardo <br />Evapotranspirometer Study of the Bureau of Reclamation has been made <br />with the Bureau providing the evapotranspiration data and Geological <br />Survey providing the remote sensing and interpretation. The object of <br />this application is to test and develop methods of remote sensing and <br />interpretation as applied to evapotranspiration. The precise evapo- <br />transpiration data from the evapotranspirometer will be used as ground <br />proof. The initial fl ights were made on May 22 and 23. Infrared color <br />photography was obtained on May 22, and three flights using recording <br />radiometer were made on May 23. The data is now being compiled and <br />analyzed. <br /> <br />Sixteen USGS publications have been publ ished to describe the Gila River <br />Phreatophyte Project, and eleven additional USGS professional papers are <br />in various stages of completion. <br /> <br />Final action of the Vegetation Management Technical Subcommittee at the <br />San Francisco meeting was to elect new officers for the coming year. <br />Paul Leger of the U. S. Forest Service was elected Chairman, and the <br />Bureau of Reclamation's representative for 1974, was elected Secretary. <br /> <br />"JF"y..;~ _~I~--~. <br /> <br />Floyd Farrell, Secretary <br />Vegetation Management <br />Technical Subcommittee <br /> <br />21 <br /> <br />
