Clear plastic bags hang from small spigots plugged into birch trunks in a  mixed stand of deciduous and coniferous trees on a hillside above the  Kispiox River in northwest B.C. Denzel Sutherland-Wilson and his  19-year-old niece, Hailey Wilson, pour the birch water collected  overnight from five trees into a 20-litre bucket, explaining they’ve  been doing this every day for a couple of weeks.
