Conductivity was monitored in four streams draining watersheds with 1 (N01B), 2 (N02B), 4 (N04D), and 20 (N20B) year target burn frequencies. Bison grazed these treatments since May 1992. Early samples were preserved with phenyl mercuric acetate.

Location of Sampling Stations: Swede Creek Quadrangle (USGS): NE1/4, NE1/4, NE1/4, W1/2, Sec 19, T11S, R8E; N01B flume: (N-22); N02B flune: (N-21); N04D flume: (L-22); N20B flume: (N-22); Shane Creek (SHAN): T-9.
Frequency of Sampling: If stream locations other than Edler Spring and hiking trail have flowing water, base flow samples are collected 3 times per week in the mornings. Edler Spring and hiking trail are sampled once per week when other sites are dry or have standing water. If the base flow collection time corresponds to a storm flow event, they are classified as such.
Variable Measured: NO3-N + NO2 -N, NH4 -N, total nitrogen (TN), soluble reactive phosphate (SRP), total phosphorus (TP), and dissolved organic carbon (DOC).
Methods: One vial is analyzed for inorganic nitrogen (N) and phosphorous (P). A second vial is run for dissolved organic carbon (DOC). The third vial is run for TN, and TP. At the completion of all analyses the vial with the maximum volume is frozen as an archived sample for 10 years from date of collection. Nitrogen and phosphorus nutrients are performed by colorimetric determination on a flow solution analyzer. Dissolved organic carbon is measured by high temperature combustion. Data is compiled annually, checked by the RA, and archived by the IM.
