On May 1, 2008, the students from Mr. Christopher Robinson's class in Philipsburg went on a CFWEP fieldtrip. They visited the following two sites: Flint Creek Campground and Douglas Creek. Below is a summary/average of the data gathered during the fieldtrip.
Flint Creek Campground, Philipsburg
Flint Creek Campground is classified as a recreational park, urban (highways), rural (dirtroads), and national forest land site that has been impacted by logging.
Water Chemistry - During the visit to the Flint Creek Campground site the air temperature was recorded at 1.07 degrees Celsius and the water temperature was recorded at 3.05 degrees Celsius. Based on the pH values, the stream seems to be neutral or slightly basic. The stream was not tested for copper, but it was tested for iron and nitrates and no concentrations were detected.
Vegetation - The common plants seen in both the riparian area and upland area were conifer trees. In the upland area Knapweed and Mullen were spotted. Most of the ground cover for both the riparian area and upland area are grasses.
Pollution Tolerance Index - The average pollution tolerance index was calculated to be 34. The top three macro invertebrates seen during the fieldtrip were Caddisflies, Mayflies, and Black Flies.
Soil Assessment - The soil texture is mostly loamy sand and is slightly acidic.
Douglas Creek
Douglas Creek is classified as a residential, urban (highways), rural (dirt roads), and Superfund/Environmental site impacted by development and mining.
Water Chemistry - During the site visit to Douglas Creek, the air temperature was 6.10 degrees Celsius and the water temperature was 4.20 degrees Celsius. Based on the pH data gathered, the stream was close to neutral. Copper concentrations were not recorded for this site; however, iron and nitrate concentrations were tested for and there was no detection of either element.
Vegetation - The common vegetation seen in both the upland area and riparian area were conifer, cottonwoods, and grasses. Knapweed was spotted in the upland area. The main source of the ground cover were weeds and grasses.
Pollution Tolerance Index - The pollution tolerance index was calculated to be 18, with Caddisflies being the most popular macro invertebrate seen during the field trip.
Soil Assessment - The soil is most like silty clay and based on the pH readings is neutral.
