This report summarizes the results of the past fourteen years of population monitoring of noxious weeds at the U.S. Air Force Academy and Farish Recreation Area ("Farish"). Base wide monitoring has been conducted at the Academy at five year intervals: 2002, 2007, 2012 and 2018. (2002, 2007, 2012 and 2017 at Farish). In between years, arial mapping at known sites was conducted at the Academy for species with low cover and permanent plots were used to monitor wide spread noxious weed species at the Academy (2018) and Farish (2016). These data are used to determine population trends. The 2018 basewide survey included 26 species that were mapped across the Academy and Farish. Four new species of noxious weeds were included in the 2018 survey, three new noxious weeds at the Academy and one at Farish.
