Macroinvertebrate Survey Collection method used: Kick-Seine or D-Net (circle). If using a kick-seine, collect samples times. If using a D-net, collect 20 scoops and record the number of scoops taken from each of the habitat areas in the table Check all of the macroinvertebrates that you find in your stream and calculate the stream s water quality rating [you may also record the number of each captured, but to calculate the rating at the bottom, only count each kind of animal once, regardless of the quantity found]. Benthic Habitat Sampled Habitat Riffle Rootwads/ woody debris/ leaf pack Submerged Undercut s # scoops Other (specify): TOTAL 20 SENSITIVE LESS SENSITIVE TOLERANT to pollution of pollution Caddisflies (except net spinners) Caddisflies, common net spinning Crayfish Aquatic worms Mayflies Dobsonflies Scuds Black flies 2 Stoneflies Fishflies Aquatic sowbugs Midge flies Watersnipe flies 0 Crane flies Clams Leeches Riffle beetles Damselflies Mussels Lunged snails Water pennies Dragonflies isopods Gilled snails 7 Alderflies 4 # of check marks (# of kinds found) 8 # of check marks (# of kinds found) count both columns under less sensitive # of check marks (# of kinds found) # above x = _42 # above x 2 = _6 # above x = Now add up the numbers you calculated for all three categories, above, and write the total # here: WATER QUALITY RATING Circle the rating that corresponds to the total of your columns.
