Mapping

Distribution

A series of slides has been developed by Aaryn Olsson that portray images of buffelgrass infestation and its development over time in a community in the Catalina Foothills. The pictures include county aerial photography and together form a time series going back to 1992.  Buffelgrass may be seen in some small patches visible on black and white imagery.  The extensive spread of buffelgrass in these communities is dramatic.
