As in previous reports, the patterns show that E.coli counts are almost entirely related to range-cattle presence or absence and that E.coli counts that could be attributable to wildlife (in the absence of cattle) are negligible or frequently nil.
The multi-year, multi-month scope of this study is unusual in that most studies monitor over shorter periods.
Our 2015-2016 results together with our other reports going back to 2007 provide compelling evidence that
E. coli contamination in streams relates directly to the presence or absence of range-cows.Testing in 2015-2016 is a continuation of earlier studies, reported in earlier articles:
The 2013 Report has a full discussion of factors affecting stream contamination (in addition to tenure holders) including the roles of Ministry of Forests and Range, Forest & Range Evaluation Program, BC Cattlemen's Association.
