Biological Monitoring Research Methodology [Biological Monitoring Background] Date:_____________________ Collector:___________________________ Stream Name:________________________(city and/or county):___________________ Landmarks and Description of Sampling Site: The sampling site is in(woods, meadow, yard, etc.): Weather Conditions This Date: Temperature of the Stream (Degrees Celsius or Fahrenheit): Width of Stream at Sampling Site (meter.centimeter): Depth of Stream Center at Sampling Site (meters.centimeter): Stream Flow: Swift    Moderate    Slow Are there fish in the stream? Yes    No Are there plants in the water? Yes    No Plants on stream bank: Trees   Grasses   Flowers    Shrubs     None The water is: Clear    Muddy    Cloudy     Oily Is there trash around or in the sampling site? Yes     No Describe the trash: Additional Observations: Assessing the Stream's Health Directions for Part One: Identify the Macroinvertebrates found at the stream sampling site using the form or the identification key, and put the number of each type in the box beside the name of each type you find. Count how many you have of each type and record the total on the line. Very Sensitive to Pollution Stonefly _____ Mayfly _____ Caddisfly _____ Riffle Beetle _____ Water Penny _____ Planarian_____ Gilled Snail_____ Dobsonfly _____ Somewhat Sensitive to Pollution Crayfish _____ Sowbug _____ Scud _____ Alderfly _____ Crane Fly _____ Fishfly _____ Aquatic Beetle _____ Dragonfly _____ Clam or Mussel_____ Damselfly _____ Watersnipe Fly _____ Whirligig _____ Not Sensitive to Pollution Aquatic Worm _____ Midge Fly _____ Leech _____ Lunged Snail _____ Black Fly _____ Directions for Part Two: Enter how many different types (not the number of each type) of macroinvertebrates you checked in each sensitivity group above. Multiply by the number in the table to get a group score. Add the three group scores. Look at the total score and circle the correct rating. Sensitivity Groups Number of Types Scoring Value   Group Score Very Sensitive   3 =   Somewhate Sensitive   2 =   Not Sensitive   1 =       Total Score =   Excellent Good Fair Poor (23 or more) (17 - 22) (11 - 16) (10 or less)
