Abstract:Nutrient data was collected monthly between April 2001 and December 2002 in collaboration with volunteers from the Ipswich R. watershed association. All samples were collected on the same day. Samples were analysed for NO3, NO2, NH4, PO4, and Si at UNH using Lachat methods. Headwater stream sites included a range of land uses in the contributing area. Samples were generally collected on the last Sunday of the month.
